The EFSA Panel on Food Additives and Flavourings (FAF Panel) provides a scientific opinion on the safety of a proposed amendment of the specifications of enzymatically produced steviol glycosides (E 960c) with respect to the inclusion of rebaudioside D produced via enzyme-catalysed bioconversion of purified stevia leaf extract. Rebaudioside D (95% on dry basis) is produced via enzymatic bioconversion of purified stevia leaf extract using uridine diphosphate (UDP)-glucosyltransferase (UGT) and sucrose synthase enzymes produced by the genetically modified yeast K. phaffii UGT-A, that facilitates the transfer of glucose to purified stevia leaf extract via glycosidic bonds. The same enzymes from K. phaffii UGT-A may be used in the manufacturing process of the food additive, rebaudioside M produced via enzyme modification of steviol glycosides from stevia (E 960c(i)). The Panel considered that separate specifications would be needed for this food additive produced via the manufacturing process described in the current application, aligned with those already established for E 960c(i). The Panel concluded that there is no toxicological concern for Rebaudioside D produced via enzymatic bioconversion of purified stevia leaf extract using UDP-glucosyltransferase and sucrose synthase produced by a genetically modified strain of the yeast K. phaffii. However, based on the available data, the Panel could not exclude the possibility that some residual amount of DNA coding for the kanamycin resistance gene could remain in the final product. Should this gene propagate in microbiota due to the presence of recombinant DNA in the final product, this would be of concern. Therefore, the Panel concluded that the safety of Rebaudioside D produced via this enzymatic bioconversion was not sufficiently demonstrated with the available data given that the absence of recombinant DNA was not shown.

International audience; The substance isobutane is intended to be used as a foaming agent at max 4.5% to produce expanded polystyrene (EPS) to be used for packaging foods, such as fruits, vegetables, meat, fish and cheese, at room temperature or lower. Isobutane is approved in Europe as a food additive (E943b) to be used quantumsatis as a gas propellant only in vegetable oil pan spray (for professional use only) and water-based emulsion spray according to Regulation (EC) No1333/2008. The purity requirements for the use of isobutane as a food additive are described in Commission Regulation (EU) No231/2012. The substance is a gas at room temperature. It is a saturated hydrocarbon, obtained with a high level of purity, and is not expected to react under the processing conditions used to make foamed polystyrene materials and articles. Data on migration of isobutane from trays at 20 degrees C for 10days ranged from 0.2 to 0.4mg/kg food. Considering the intended applications, estimated exposure is extremely low based on migration data. In the absence of genotoxicity alerts and given the very low toxicity following repeated exposure with no observed adverse effect concentration (NOAEC) of several thousands of mg/m(3) by inhalation, it was considered that the use of isobutane as a foaming agent, at the expected exposure from food, does not raise a safety concern.

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process EstPak Plastik (EU register No RECYC150), which is based on the Starlinger Decon technology. The decontamination efficiency of the process was demonstrated by a challenge test. The input of this process is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, mainly bottles, containing no more than 5% of PET from non‐food consumer applications. In this technology, washed and dried PET flakes are preheated before being submitted to solid‐state polycondensation (SSP) in a continuous reactor (one single reactor or several reactors in parallel) at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the continuous SSP reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control the performance of the process are well defined and are temperature, pressure, residence time and gas flow for steps 2 and 3. Under these conditions, it was demonstrated that the recycling process under evaluation, using the Starlinger Decon technology, is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process intended to be used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long‐term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this PET are not intended to be used, and should not be used, in microwave and conventional ovens.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on phenylcapsaicin as a novel food (NF) pursuant to Regulation (EU) 2015/2283. Phenylcapsaicin is a chemically synthesised analogue of capsaicin intended to be marketed in food supplements and in foods for special medical purposes to the general population above the age of 11 years old at a maximum level of 2.5 mg/day. The highest intake of the NF is 2.5 mg/day which corresponds to 36 mu g/kg body weight (bw) per day for adults, and 58 mu g/kg bw per day for adolescents (10-14 years). The Panel considers that there is no concern with respect to genotoxicity of the NF. The reference point derived based on a 13-week rat study was the lowest of the model averaged BMDL20 values of 37.2 mg/kg bw per day in females for increased plasma alanine aminotransferase (ALAT) levels. The Panel concludes that the NF, phenylcapsaicin, is safe under the proposed uses and use levels. (C) 2019 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on a botanical extract derived from both Panax notoginseng and Astragalus membranaceus (AstraGin (TM)) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is a combination of an ethanol extract of the roots of A. membranaceus and a hot water extract of the roots of P notoginseng. The NF contains 1.5-5% total saponins, 0.1-0.5% ginsenoside Rb1 and 0.01-0.1% astragaloside I. Both plants that are used to produce the NF have a long history of use, especially in traditional Chinese medicine. Information on the production process and the composition of the NF is sufficient and does not raise safety concerns. The applicant proposed to use the NF as a food supplement for the general adult population, excluding pregnant women, at a maximum daily amount of 350 mg. Taking into account these conditions of use, the Panel considers that the consumption of the NF is not nutritionally disadvantageous. The provided genotoxicity studies do not raise concerns for genotoxicity of the NF. Based on the findings of a subchronic toxicity study, supported by a subacute toxicity study, the Panel identified the overall no observed adverse effect level (NOAEL) of the NF at 100 mg/kg body weight (bw) per day. By applying an uncertainty factor of 200, the Panel concludes that the NF is safe at an intake level of 0.5 mg/kg bw per day, corresponding to a maximum daily intake of 35 mg of the NF for the target population, i.e. adults excluding pregnant women.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on 6'-Sialyllactose (6'-SL) sodium salt as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of the human-identical milk oligosaccharide (HiMO) 6'-SL but also contains D-lactose, sialic acid and a small fraction of other related oligosaccharides. The NF is produced by fermentation with a genetically modified strain of Escherichia coil K-12 DH1. The information provided on the manufacturing process, composition and specifications of the NF does not raise safety concerns. The applicant intends to add the NF in a variety of foods, including infant and follow-on formula, foods for infants and toddlers, foods for special medical purposes and food supplements. The target population is the general population. The anticipated daily intake of 6'-SL from the NF at the maximum proposed use levels is unlikely to exceed the intake level of naturally occurring 6'-SL in breastfed infants on a body weight basis. The intake of 6'-SL in breastfed infants on a body weight basis is expected to be safe also for other population groups. The intake of other carbohydrate-type compounds structurally related to 6'-SL is also considered of no safety concern. Food supplements are not intended to be used if other foods with the added NF or breast milk are consumed on the same day. The Panel concludes that the NF is safe under the proposed conditions of use. (C) 2020 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on 3'-Sialyllactose (3'-SL) sodium salt as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of the human identical milk oligosaccharide (HiMO) 3'-SL but also containing D-lactose, sialic acid and a small fraction of other related oligosaccharides resulting in a fully characterised mixture of carbohydrates. The NF is produced by fermentation with a genetically modified strain of Escherichia coif K-12 DH1. The information provided on the manufacturing process, composition and specifications of the NF does not raise safety concerns. The applicant intends to add the NF in a variety of foods, including infant and follow-on formula, foods for infants and toddlers, foods for special medical purposes and food supplements. The target population is the general population. The anticipated daily intake of 3'-SL from the NF at the maximum proposed use levels is unlikely to exceed the intake level of naturally occurring 3'-SL in breastfed infants on a body weight basis. The intake of 3'-SL in breastfed infants on a body weight basis is expected to be safe also for other population groups. The intake of other carbohydrate-type compounds structurally related to 3'-SL is also considered of no safety concern. Food supplements are not intended to be used if other foods with added NF (as well as breast milk, milk, fermented milk-based products and selected cheeses retaining milk sugar (e.g. curd cheese) for infants and young children) are consumed on the same day. The Panel concludes that the NF is safe under the proposed conditions of use for the proposed target populations. (C) 2020 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of dried whole cell Euglena gracilis as a novel food (NF) pursuant to Regulation (EU) 2015/2283. E. gracilis is a single-cell microalga which occurs widely in nature and is commonly found in freshwater habitats. The NF, the dried biomass of E. gracilis, is produced by fermentation and its major constituent (> 50%) is a beta-glucan polysaccharide. The applicant proposed to use the NF in food supplements, in foods for total diet replacement for weight control and as a food ingredient added to a number of food products. The target population proposed by the applicant is the general population, except for food supplements and for foods for total diet replacement for which the target population is the general population from 12 months of age onwards. In 2019, E. gracilis was attributed the qualified presumption of safety (QPS)-status with the qualification 'for production purposes only, which includes food products based on microbial biomass of the microalga. Based on the information provided, E. gracilis is not expected to survive the manufacturing process. The submitted toxicity studies did not raise safety concerns. No adverse effects were observed in the subchronic toxicity study, up to the highest dose tested, i.e. 3,300 mg NF/kg body weight, considered as the no observed adverse effect level (NOAEL). The margins of exposure between this dose and the high (95th percentile) intake estimates, range from 33 for infants to 192 for adults. The Panel considers that in view of the QPS status of the source of the NF, supported by the compositional data and lack of toxicity observed in the 90-day study, the margins of exposure are sufficient. The Panel considers that the NF, i.e. dried whole cell Euglena gracilis, is safe at the proposed uses and use levels. (C) 2020 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Allergens (NDA) was asked to deliver an opinion on nicotinamide riboside chloride as a novel food (NF) pursuant to Regulation (EU) 2015/2283, including an evaluation of the safety of its use in food supplements as a source of niacin, and the bioavailability of nicotinamide from this source, in the context of Directive 2002/46/EC. The NF, a synthetic form of nicotinamide riboside, is proposed to be used in food supplements for the healthy adult population at levels up to 300 mg/day. The production process, composition, specifications, batch-to-batch variability and stability of the NF do not raise safety concerns. Animal and human data indicate that the NF contributes to the nicotinamide body pool. There are no concerns regarding genotoxicity. Human studies do not raise safety concerns. The proposed maximum use level corresponds to an amount of nicotinamide, which is sixfold lower than the tolerable upper intake level (UL) set for adults, excluding pregnant and lactating women. The margin of exposure (MoE) of 70 derived from repeated dose toxicity studies with rats and dogs is considered sufficient for the adult population, excluding pregnant and lactating women. Regarding these two population groups, the MoE of 76 derived from a developmental toxicity study in rats is considered insufficient in the absence of data which could justify accepting a MoE lower than 100. The Panel concludes that the NF is safe under the proposed conditions of use for the healthy adult population, excluding pregnant and lactating women, and that an intake of the NF up to 230 mg/day is safe for pregnant and lactating women. The Panel also concludes that the NF is a source from which nicotinamide, a form of niacin, is bioavailable. (C) 2019 European Food Safety Authority.

International audience; The food enzyme is an alpha-amylase (4-alpha-D-glucan glucanohydrolase; EC 3.2.1.1) produced with the genetically modified Bacillus licheniformis strain NZYM-AV by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme does not contain the production microorganism or its DNA; therefore, there is no safety concern for the environment. The alpha-amylase is intended to be used in starch processing for the production of glucose syrups and distilled alcohol production. Residual amounts of total organic solids (TOS) are removed by distillation and by the purification steps applied during the production of glucose syrups (by > 99%). Consequently, dietary exposure was not calculated. Genotoxicity tests did not raise a safety concern. The subchronic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rodents. The Panel derived a no observed adverse effect level (NOAEL) at the highest dose level of 796 mg TOS/kg body weight (bw) per day. The allergenicity was evaluated by comparing the amino acid sequence to those of known allergens and one match was found. The Panel considered that, under the intended condition of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood is considered low. Based on the microbial source, the genetic modifications, the manufacturing process, the compositional and biochemical data, the removal of TOS during the intended food production processes and the toxicological and genotoxicity studies, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; The food enzyme is a glucose oxidase (beta-D-glucose:oxygen 1-oxidoreductase; EC 1.1.3.4) produced with a genetically modified strain of Aspergillus oryzae strain NZYM-KP by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme does not contain the production organism or DNA; therefore, there is no safety concern for the environment. The glucose oxidase is intended to be used in baking processes. Based on the maximum use levels recommended and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.156 mg TOS/kg body weight (bw) per day in European populations. The food enzyme did not induce gene mutations in bacteria or chromosome aberrations in human lymphocytes. The subchronic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rodents. A no-observed-adverse-effect level was derived (341 mg TOS/kg bw per day), which compared with the estimated dietary exposure results in a sufficiently high margin of exposure. The allergenicity was evaluated by comparing the amino acid sequence to those of known allergens and one match with a fungal contact allergen was found. The Panel considered that, under the intended condition of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood is considered low. Based on the microbial source, the genetic modifications, the manufacturing process, the compositional and biochemical data, the estimated dietary exposure and the findings in the toxicological studies, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety evaluation of the recycling process Gneuss 1 (EU register No RECYC0143). The input is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% of PET from non-food applications. They are extruded under vacuum into pellets or sheets. Having examined the challenge test provided, the Panel concluded that the decontamination in the extruder under vacuum degassing is the critical step for the decontamination efficiency of the process. The operating parameters to control its performance are well defined and are temperature, pressure, residence time, throughput rate, rotor speed and satellite screws speed. The operating parameters of this step are at least as severe as those obtained from the challenge test. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 mu g/kg food. Therefore, the recycled PET obtained from the process Gneuss 1 intended for the manufacture of articles made with up to 100% recycled post-consumer PET and intended for contact for long-term storage at room temperature with all types of foodstuffs is not considered of safety concern. Trays made of this recycled PET are not intended to be used, and should not be used, in microwave and conventional ovens.

International audience; The food enzyme considered in this opinion is an endo-l,4-beta-xylanase (4-beta-D-xylan xylanohydrolase; EC 3.2.1.8) produced from the genetically modified Bacillus subtilis strain LMG S-27588 by the company Puratos N. V. The production strain was not detected in the food enzyme. The endo-1,4-beta-xylanase is intended to be used in baking processes. Based on the maximum use levels recommended and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.325 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests with the food enzyme indicated no genotoxic concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rodents. A no observed adverse effect level (NOAEL) was derived (443 mg TOS/kg bw per day), which, compared with the dietary exposure, results in a sufficiently high margin of exposure. The allergenicity was evaluated by comparing the amino acid sequence to those of known allergens; no match was found. The Panel considered that there are no indications for food allergic reactions to this endo-1,4-beta-xylanase by dietary exposure. Based on the genetic modifications, the manufacturing process, the compositional and biochemical data, the dietary exposure assessment, the findings in the toxicological studies and allergenicity assessment, the Panel concludes that this food enzyme does not give rise to safety concerns under the intended conditions of use. The Panel noted that recombinant DMA was present in all batches of the food enzyme tested.

International audience; The food enzyme considered is a maltogenic amylase (glucan 1,4-beta-maltohydrolase; EC 3.2.1.133) produced with the genetically modified Bacillus subtilis strain NZYM-SM by Novozymes A/S. The food enzyme contains neither the production organism nor recombinant DNA. The maltogenic amylase is intended for use in baking processes and starch processing for glucose syrups production. Based on the maximum use levels recommended for the food processes and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-Total Organic Solids (TOS) was estimated to be up to 0.168 mg T'OS/kg body weight (bw) per day in European populations. The food enzyme did not induce gene mutations in bacteria or chromosomal aberrations in human lymphocytes. The subchronic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rodents. A no observed adverse effect level (NOAEL) was derived (320 mg TOS/kg bw per day), which, compared with the dietary exposure, results in a sufficiently high margin of exposure. The allergenicity was evaluated by searching for similarity of the amino acid sequence to those of known allergens. Three matches to occupational respiratory allergens were found, however, the Panel considered that there are no indications for food allergic reactions to the food enzyme. Based on the genetic modifications performed, the manufacturing process, the compositional and biochemical data provided, the dietary exposure assessment, the findings in the toxicological studies and allergenicity assessment, the Panel concluded that the food enzyme maltogenic amylase from Bacillus subtilis strain NZYM-SM does not give rise to safety concerns under the intended conditions of use.

International audience; The food enzyme is an endo-1,4-beta-xylanase (EC 3.2.1.8) produced with a genetically modified strain of Aspergillus niger (strain XEA), by DSM Food Specialities B.V. The food enzyme is intended to be used in baking and brewing processes. Based on maximum use levels recommended for the food processes and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.310 mg TOS/kg body weight per day in European populations. Genotoxicity tests with the food enzyme did not indicate a genotoxic concern. A repeated dose 90-day oral toxicity study in rodents, carried out with this endo-1,4-beta-xylanase, showed no concern with respect to systemic toxicity. The allergenicity was evaluated by searching for similarity of the amino acid sequence to those of known allergens; no match was found. The Panel considers that there are no indications for allergic sensitisation and elicitation reactions by dietary exposure to the food enzyme endo-1,4-beta-xylanase. Based on the microbial source, the genetic modifications performed, the manufacturing process, the compositional and biochemical data provided, the dietary exposure assessment, the findings in the toxicological studies and the allergenicity assessment, the Panel concludes that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process BTB PET direct IV+ (EU register number RECYC0152). The input of the process is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer food contact PET containing no more than 5% of PET from non-food consumer applications. In this technology, washed PET flakes are extruded into pellets which are further crystallised. Crystallised pellets are then preheated and fed to the solid-state polycondensation (SSP) reactor. Having examined the challenge test provided, the Panel concluded that extrusion, crystallisation and SSP are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and they are temperature, pressure and residence time. Under these conditions, it was demonstrated that the recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 mu g/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process, intended to be used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET are not intended to be used, and should not be used, in microwave and conventional ovens.

International audience; The food enzyme considered in this opinion is aquaiysin 1 (EC 3,4.21.111), produced from the genetically modified strain Bacillus subtilis LMGS 25520 by Puratos NV. The production strain was not detected in the food enzyme. Aquaiysin 1 is intended to be used in baking processes. Based on the maximum use level recommended and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme total organic solids (TOS) was estimated to be up to 2.13 mg TOS/kg body weight per day in European populations. Genotoxicity tests indicated no genotoxic concerns. The allergenicity was evaluated by searching for similarity of the amino acid sequence to those of known allergens and 23 matches were found (20 respiratory and 3 dermal allergens). However, the Panel considered that there are no indications for food allergic reactions to the food enzyme. The genetic modifications performed, the manufacturing process, the compositional and biochemical data, the allergenicity and the genotoxicity assessment did not raise safety concerns. The Panel considered the margin of exposure (MOE) calculated from the no observed adverse effect level (INOAEL) determined from the repeated dose 90-day oral toxicity study and the estimated dietary exposure as insufficient to conclude that there is no safety concern for this food enzyme under the intended conditions of use. The Panel noted that recombinant DNA was present in all batches of the food enzyme tested.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety evaluation of the recycling process Gneuss 2 (EU register No RECYC0144). The input is washed and dried poly(ethylene terephthalate)(PET)flakes originating from collected post-consumer PET containers, containing no more than 5% of PET from non-food applications. They are extruded under vacuum into pellets or sheets. Having examined the challenge test provided, the Panel concluded that the decontamination in the extruder under vacuum degassing is the critical step for the decontamination efficiency of the process. The operating parameters to control its performance are well defined and are temperature, pressure, residence time, throughput rate, the rotor speed and the satellite screws speed. The operating parameters of this step are at least as severe as those obtained from the challenge test. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 mu g/kg food. Therefore, the recycled PET obtained from the process Gneuss 2 intended for the manufacture of articles made with up to 90% recycled post-consumer PET and intended for contact for long-term storage at room temperature with all types of foodstuffs is not considered of safety concern. Trays made of this recycled PET are not intended to be used, and should not be used, in microwave and conventional ovens.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of poly((R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate) (PHBH), CAS No 147398-31-0 and food contact material (FCM) substance No 1059. This biodegradable copolymer is produced by fermentation of palm oil using a genetically modified microorganism (Cupriavidus necator). Overall migration was up to 5.4 mg/kg. Oligomers are hydroxyl-terminated or with crotyl- and hexenyl end-groups from dehydration of hydroxyl end-groups. In the absence of calibration standards, the total oligomer migration was set at the overall migration values. Other degradation products are crotonic acid and (E)-2-hexenoic acid. Crotonic acid is authorised for use in FCMs with a specific migration limit (SML) of 0.05 mg/kg food. For (E)-2-hexenoic acid, no indication for genotoxicity was identified by the EFSA CEF Panel in its group evaluation of flavouring substances in FGE.05Rev2 (EFSA CEF Panel, 2010b). The other migrating substances detected, ■■■■■, are from the authorised substance 'palm oil and/or palm fatty acid distillate' (FCM substance No 9) used as a carbon source for the fermentation and do not give rise to safety concern. A PHBH oligomer mixture was synthesized to simulate that migrating. It did not give rise to concern for genotoxicity. From the repeated dose 90-day oral toxicity study in rats, the Panel identified the no-observed-adverse-effect level (NOAEL) at the highest dose tested in males, 1,364 mg/kg body weight (bw) per day. The Panel concluded that the potential for bioaccumulation of oligomers is low. Overall, the CEP Panel concluded that the substance PHBH is not of safety concern for the consumer if it is used alone or blended with other polymers in contact with all kinds of food during more than 6 months at room temperature or below, including hot-fill or a short heating up phase. The specific migration of all oligomers

International audience; The food enzyme is an alpha-amylase (4-alpha-D-glucan glucanohydrolase; EC 3.2.1.1) produced with a genetically modified Bacillus licheniformis strain NZYM-AN by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme does not contain the production organism or recombinant DNA; therefore, there is no safety concern for the environment. The alpha-amylase is intended to be used in starch processing for the production of glucose syrups and distilled alcohol production. Residual amounts of total organic solids (TOS) are removed by distillation and by the purification steps applied during the production of glucose syrups (by > 99%). Consequently, dietary exposure was not calculated. Genotoxicity tests with the food enzyme did not raise a safety concern. The amino acid sequence of the food enzyme did not match to those of known allergens. The Panel considered that under the intended condition of use, the risk of allergic sensitisation and elicitation reactions upon dietary exposure to this food enzyme cannot be excluded, but the likelihood is considered low. Based on the microbial source, the genetic modifications, the manufacturing process, the compositional and biochemical data, the removal of TOS during the intended food production processes and the findings in the genotoxicity studies, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; This scientific opinion of the EFSA Panelon Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) deals with the safety assessment of selenium nanoparticles, FCM substance No 1070, which is intended to be used as an antioxidant. Selenium nanoparticles are incorporated into the adhesive middle layer of multilayer laminates with an outside polyethylene terephthalate (PET) layer and an inner polyolefin (food contact) layer. The final materials are intended to be used for contact with all food types that are susceptible to oxidation. The specific migration of total selenium was tested using multilayer pouches containing selenium nanoparticles at 0.002mg/dm(2) and filled with 3% acetic acid and 20%, 50% or 95% ethanol for 10 days at 60 degrees C. In all tests, migration of selenium was not detectable. Taking into account current knowledge on the diffusional properties of nanoparticles in polymers, the CEF Panelconcluded that there is no safety concern for the consumer if selenium nanoparticles are used in multilayer films and separated from the food by a polyolefin food contact layer for any type of food and under any food contact conditions.

International audience; The food enzyme is an alpha-amylase (4-alpha-D-glucan glucanohydrolase; EC 3.2.1.1), produced with the genetically modified Aspergillus niger strain NZYM-SB by Novozymes A/S. The food enzyme does not contain the production organism or its DNA; therefore, there is no safety concern for the environment. The alpha-amylase is intended for use in starch processing, beverage alcohol (distilling) processes and baking processes. Residual amounts of total organic solids (TOS) are removed by distillation and by the purification steps applied during the production of glucose syrups (by > 99%). Consequently, dietary exposure was not calculated for these two uses. Based on the maximum use levels recommended for the baking processes and individual consumption data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-TOS was estimated to be up to 3.075 mg TOS/kg body weight per day in European populations. The food enzyme did not induce gene mutations in bacteria or micronuclei in human lymphocytes. Subchronic toxicity was assessed by means of a repeated-dose 90-day oral toxicity study in rodents. A no observed adverse effect level (NOAEL) was derived that, compared with the dietary exposure, resulted in a sufficiently high margin of exposure (MOE). Similarity of the amino acid sequence to those of known allergens was searched and two matches were found. The Panel considered that the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood is considered low. Based on the genetic modifications, the manufacturing process, the compositional and biochemical data, the findings in the toxicological and genotoxicity studies, as well as the estimated dietary exposure, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the Linpac recycling process (EU register number RECYC0148), which is based on the Linpac super clean technology. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, containing no more than 5% PET from non‐food consumer applications. In this technology post‐consumer washed and dried PET flakes are heated in continuous driers under gas flow before being extruded. Having examined the results of the challenge test provided, the Panel concluded that the decontamination in the driers (steps 2 and 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters controlling its performance are well defined and are residence time, ‘air flow per mass of flakes’ and temperature in the driers. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.15 μg/kg food, derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when used at up to 100% to make articles intended for contact with all types of foodstuffs, except packaged water. These articles should be used at conditions covered by migration testing of 10 days at 20°C. The articles are not intended to be used, and should not be used, in microwave and conventional ovens.

International audience; his scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the 4PET recycling process (EU register number RECYC0139), which is based on the EREMA Basic technology. The input to this process is hot washed and dried poly(ethylene terephthalate) ( PET) flakes originating from collected post-consumer PET containers, containing no more than 5% PET from non-food consumer applications. In this technology, post-consumer washed and dried PET flakes are heated in a continuous reactor under vacuum before being extruded. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor step (step 2) is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.15 lg/kg food, derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when the final thermoformed trays and containers and PET beverage bottles manufactured with the recycled pellets and not used for packaging water or ready-to-feed liquid infant formulae contain up to 90% recycled post-consumer PET. These thermoformed trays are not intended to be used and should not be used in microwave and conventional ovens.

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the substance phosphorous acid, mixed 2,4‐bis(1,1‐dimethylpropyl)phenyl and 4‐(1,1‐dimethylpropyl)phenyl triesters. The substance was evaluated by the CEF Panel in 2011 and 2,4‐di‐tert‐amylphenol, an impurity and hydrolysis product was re‐evaluated by the CEF Panel in 2015. In this application, the applicant requested an increase of the specific migration limit of the substance, currently established at 5 mg/kg food, to 10 mg/kg food, and provided new toxicological studies. Findings from three new in vitro mutagenicity assays on the oxidation products support the conclusion from 2011 that the substance and its oxidation products are not genotoxic. A new toxicokinetic study on the substance supports the consideration from the evaluation in 2011 that the substance does not raise concern for accumulation. The outcome of a new delayed neurotoxicity study on a structurally related substance, phosphorous acid, tris (2,4‐di‐tert‐butylphenyl) ester, which was considered not to cause neurotoxicity in hens, strengthens the conclusion of the Panel in 2011 that the substance does not represent a concern for neurotoxicity. From a new two‐generation reproduction toxicity study and a prenatal developmental toxicity study on the substance, a new subchronic toxicity study on its oxidation products that completes the one submitted in 2011 on the substance itself, and a 2‐year oral toxicity study on the structurally related substance, the lowest NOAEL was 58–147 mg/kg bw per day (from the 2‐year oral toxicity study). Compared to the requested increase of the migration limit, this gives an acceptable margin of safety of 348. Therefore, the CEF Panel concluded that an increase of the specific migration limit of the substance from 5 to 10 mg/kg food is not a safety concern for the consumer.

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on proline-specific oligopeptidase (Tolerase (R) G) as a novel food ingredient submitted pursuant to Regulation (EC) No 258/97 of the European Parliament and of the Council, taking into account the comments and objections of a scientific nature raised by Member States. The novel food is an enzyme preparation of prolyl-oligopeptidase produced with a genetically modified Aspergillus niger self clone strain. The target population is the general adult population. The results from a bacterial reverse mutation test and of an in vitro chromosome aberration test did not indicate genotoxicity. The Panel considers that the reported effects observed in a 90-day rat study are treatment-related effects and can be attributed to the higher energy consumption by these animals. Taking into account the intended maximum use level for Tolerase (R) G, its daily consumption would correspond to 2,746 mg TOS/person or to 39.2 mg TOS/kg body weight (bw) per day, when considering a default body weight of 70 kg for an adult person. The margin between this value and the dose in the rats, which caused effects attributable to the excess energy intake, is approximately 45. Noting this margin, the Panel considers that it is unlikely that such effects would occur in human at the intended use levels. The Panel concludes that the NF, Tolerase (R) G, is safe for the intended use at the intended use level. (C) 2017 European Food Safety Authority.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety evaluation of the recycling process Coexpan Montonate (EU register No RECYC0141), which is based on the Starlinger Decon technology. The decontamination efficiency of the process was demonstrated by a challenge test. The input of this process is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, mainly bottles, containing no more than 5% of PET from non-food consumer applications. In this technology, washed and dried PET flakes are preheated before being submitted to solid-state polycondensation (SSP) in a continuous reactor at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the continuous SSP reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and are temperature, pressure, residence time and gas flow for step 2 and 3. Under these conditions, it was demonstrated that the recycling process under evaluation, using the Starlinger Decon technology, is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 lg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process intended to be used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this PET are not intended to be used, and should not to be used in microwave and conventional ovens.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000 Commission Regulation No 1565/2000 of 18 July 2000 laying down the measures necessary for the adoption of an evaluation programme in application of Regulation (EC) No 2232/96. Official Journal of the European Communities L 180, 19.7.2000, 8–16. . The present consideration concerns a group of 29 aliphatic secondary alcohols, ketones and related esters evaluated by JECFA at the 59th and 69th meetings in 2002 and 2008. This revision is made due to the inclusion of nine additional substances cleared for genotoxicity concern in FGE.205 Revision 1. The substances were evaluated through a stepwise approach that integrates information on structure–activity relationships, intake from current uses, toxicological threshold of concern and available data on metabolism and toxicity. The Panel agrees with the application of the Procedure as performed by JECFA for all 29 substances considered in this FGE. For all substances, the Panel concludes that there is ‘no safety concern at the estimated levels of intake as flavouring substances based on the MSDI approach’. For all 29 substances, the specifications for the materials of commerce have also been considered and found adequate. Ten out of the 14 substances for which use levels became available exceed the modified theoretical added maximum daily intake (mTAMDI) and more reliable exposure data are required to finalise their evaluation. On the basis of such data, additional toxicological data might become necessary. For 15 substances, use levels are needed to calculate the mTAMDIs in order to identify those flavouring substances that need more refined exposure assessment to finalise the evaluation.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the recycling process Alimpet (EU register number RECYC0136), which is based on the EREMA Multi-Purpose Reactor (MPR) technology. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% PET from non-food consumer applications. In this technology, post-consumer washed and dried PET flakes are heated in a continuous reactor under vacuum. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor step (step 2) is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.15 lg/kg food derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when used in extruded PET sheet for thermoforming trays and containers made with up to 100% recycled post-consumer PET, and used for contact with all types of foodstuff except packaged water, for long-term storage at room temperature. Thermoformed trays are not intended to be used and should not be used in microwave and conventional ovens.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. The present consideration concerns a group of four flavouring substances consisting of isopulegone and three other substances evaluated by JECFA at the 55th meeting. This revision is made due to additional toxicity data available for (1R,2S,5R)‐isopulegol [FL‐no: 02.067]. The substances were evaluated through a stepwise approach that integrates information on structure–activity relationships, intake from current uses, toxicological threshold of concern, and available data on metabolism and toxicity. p‐Mentha‐1,4(8)‐dien‐3‐one [FL‐no: 07.127] is no longer supported by the flavour industry and was not evaluated. In agreement with JECFA, the Panel evaluated the candidate substances in this Flavouring Group Evaluation (FGE) via the B‐side of the Procedure. Based on a no observed adverse effect level (NOAEL) from a 90‐day oral toxicity study on [FL‐no: 02.067], adequate margins of safety for the three candidate substances could be calculated. Therefore, the Panel agrees with the JECFA conclusion, ‘No safety concern at estimated levels of intake as flavouring substances’ based on the maximised survey‐derived daily intake (MSDI) approach. Besides the safety assessment of these flavouring substances, the specifications for the materials of commerce have also been considered and found adequate. For the three substances evaluated in this FGE, use levels have become available and the modified theoretical added maximum daily intakes (mTAMDIs) were estimated. For [FL‐no: 02.067 and 07.067], the mTAMDI exceeds the toxicological threshold of concern for their structural classes and need more refined exposure assessment to finalise the evaluation.

International audience; Benzophenone [FL-no: 07.032] has been evaluated as a flavouring substance, in FGE.69, by the EFSA Panelon Food Additives, Flavourings, Processing Aids and Materials in Contact with Food in 2008. Benzophenone was evaluated also by JECFA ([, 2011]) and by IARC ([, 2013]) based on studies that were not considered in the EFSA opinion on FGE.69. Therefore, the Commission requested the CEF Panelto carry out a review of existing literature on the safety of this flavouring substance. In the framework of the evaluation of benzophenone as a food contact material, the CEF Panelestablished a tolerable daily intake (TDI) of 0.03 mg/kg body weight (bw) per day (2009). In the present Opinion, the Panelconsidered the already existing evaluations by EFSA, JECFA, IARC and available literature data on benzophenone toxicity. Moreover, new data on the use levels of benzophenone as a flavouring substance have been provided. The Panelconsiders that there is no concern with respect to genotoxicity. The Panelconsiders the endocrine activities of benzophenone and its metabolite 4-hydroxybenzophenone as weak and not directly related to the observed toxic effects including the neoplastic effects in rodents. The Panelconfirms that the conservative approach taken by EFSA (2009) to derive a TDI of 0.03mg/kg bw for benzophenone is appropriate to cover the non-neoplastic effects in the chronic toxicity studies and the neoplastic effects induced in the rodent carcinogenicity studies. The TDI is in the same order of magnitude as the chronic dietary exposure of adults and children to benzophenone (10-20 mu g/kg bw per day) for the amount of added flavouring substance. The Panelconsiders that the calculated TDI and exposure estimate are based on conservative assumptions. The Panelconcludes that there is no safety concern for benzophenone under the current condition of use as a flavouring substance.

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to carry out the additional assessment for taxifolin‐rich extract from Dahurian Larch as a food ingredient in the context of Regulation (EC) No 258/97. The novel food (NF) is a taxifolin‐rich water–ethanol extract from the wood of the Dahurian Larch and contains a minimum of 90% taxifolin. The Panel considers that the taxifolin‐rich extract is sufficiently characterised and that its compositional data and specifications do not raise safety concerns. The NF is intended to be added to non‐alcoholic beverages, to yogurt and to chocolate confectionery. The Panel considers that the data on genotoxicity do not raise concern. In a subchronic rat study performed in accordance with OECD standards, the highest dose tested (i.e. 1,500 mg/kg bw) was considered to be the NOAEL. The margin of exposure (MOE) of the combined intake (158 mg) from the intended food uses (including 100 mg from food supplements) would result to about 660 for an adult weighing 70 kg. For adolescents, taking into account a default body weight of 45 kg, the MOE of the combined intake (146 mg) would be about 460. In the absence of a high percentile intake estimate for children between 9 and 14 years of age, the Panel considers the P97.5 intake estimate from the intended food uses (except from food supplements) for children between 10 and 17 years, i.e. 46 mg/day. Taking into account a default body weight of 29.4 kg (P5 body weight for children aged 10–14 years as suggested by EFSA Scientific Committee ()), the resulting MOE would be about 960.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids was requested to evaluate 53 flavouring substances attributed to the Flavouring Group Evaluation 07, including four new substances but‐3‐en‐2‐ol, non‐1‐en‐e‐ol, hex‐1‐en‐3‐one and 1‐nonene‐3‐one [FL‐nos: 02.131, 02.187, 07.161 and 07.210] in this Revision 5, using the Procedure in Commission Regulation (EC) No 1565/2000. None of the 53 substances was considered to have genotoxic potential. The substances were evaluated through a stepwise approach that integrates information on the structure–activity relationships, intake from current uses, toxicological threshold of concern (TTC), and available data on metabolism and toxicity. The Panel concluded that all 53 substances do not give rise to safety concerns at their levels of dietary intake, estimated on the basis of the ‘Maximised Survey‐derived Daily Intake’ (MSDI) approach. Besides the safety assessment of the flavouring substances, the specifications for the materials of commerce have also been considered and found adequate. For 50 substances, further information is required based on comparison of the ‘modified Theoretical Added Maximum Daily Intakes’ (mTAMDIs) with the TTCs. This would include more reliable intake data and then, if required, additional toxicological data.

International audience; This scientific opinion of the EFSA Panelon Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process PEGRA-V (EU register number RECYC0137), which is based on the Starlinger IV+((R)) technology. The input of the process is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% of PET from non-food consumer applications. In this technology, washed PET flakes are dried and crystallised in a reactor, then extruded into pellets which are further crystallised in a second reactor. Crystallised pellets are then preheated in a third reactor and fed to the solid-state polycondensation (SSP) reactor. Having examined the challenge test provided, the Panelconcluded that the three steps, drying and crystallisation, extrusion and crystallisation and SSP are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and they are the temperature, the gas flow and the residence time for the drying and crystallisation step, and the temperature, the pressure and the residence time for the extrusion and crystallisation step and the SSP step. Under these conditions, it was demonstrated that the recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1g/kg food. Therefore, the Panelconcluded that the recycled PET obtained from this process intended to be used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET are not intended to be used, and should not to be used in microwave and conventional ovens.

The food enzyme considered in this opinion is a β‐amylase (EC 3.2.1.2) from soybean submitted by Nagase (Europa) GmbH. This β‐amylase is intended to be used in the starch processing for maltose syrup production and the manufacture of a Japanese rice cake type. Based on the maximum use levels recommended for the respective food processes, dietary exposure to the food enzyme–total organic solids (TOS) was estimated on the basis of Japanese consumption data. Conservative average infant formula consumption, as reported in the EFSA Draft Guidance on risk assessment of substances present in food intended for infants below 16 weeks of age, was used to estimate the exposure to a fraction of soybean comparable to the food enzyme–TOS, resulting from the consumption of soybean‐derived foods. The exposure estimate to the food enzyme–TOS was found to be lower than the comparable fraction from the source material. Potential allergenicity of the β‐amylase was evaluated by searching for similarity of the amino acid sequence to those of known allergens, and no match was found. The β‐amylase is produced from soybean, which is a known allergenic food. Japanese rice cake, consequently, may contain traces of soybean allergens, which may give rise to safety concerns in soybean‐allergic consumers. Based on the origin of the food enzyme from edible parts of soybean, the manufacturing process, the compositional and biochemical data provided and the dietary intake estimates, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use, except that Japanese rice cake produced with this food enzyme may contain traces of soybean allergens.

International audience; The EFSA Panelon Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) was requested by the European Commission according to Art. 29 1(a) of the Regulation (EC) No178/2002 to carry out a review of existing literature on the safety of ethyl acrylate [FL-no: 09.037] when used as a flavouring substance. Ethyl acrylate [FL-no: 09.037] was evaluated in 2010 by EFSA in FGE.71 as a flavouring substance, based on the 2006 JECFA evaluation. The Panelconcluded that ethyl acrylate was of no safety concern at estimated level of intake as flavouring substance based on the Maximised Survey-Derived Daily Intake (MSDI) approach. The Panelhas evaluated the new literature available and any previous assessments performed by JECFA (2006) and EFSA (2010). Moreover, new data on the use levels of ethyl acrylate as flavouring substance have been provided. For use as flavouring substance, the chronic dietary exposure estimated using the added portions exposure technique (APET), is calculated to be 3,545 mu g/person per day for a 60-kg adult and 2,233 mu g/person per day for a 15-kg 3-year-old child. Exposure from food contact materials may be up to 6,000 mu g/person per day. The Panelconsidered that based on the available data, which covers all relevant genetic endpoints (i.e.gene mutations, structural and numerical chromosomal aberrations) there is no concern with respect to genotoxicity of ethyl acrylate. The Panelevaluated the available carcinogenicity studies conducted in rats and mice and agreed with the NTP evaluation (1998) concluding that the forestomach squamous cell papilloma and carcinoma observed in rodents were not relevant to humans. Additionally, there was no evidence of systemic toxicity in short-term and subchronic toxicity studies. Therefore, the Pane lconcluded that there is no safety concern for the use of ethyl acrylate as a flavouring substance, under the intended conditions of use.

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of dimethyl carbonate used as monomer for making a polycarbonate prepolymer with 1,6‐hexanediol and then reacted with 4,4′‐methylenediphenyldiisocyanate (MDI) and diols, such as polypropylene glycol and 1,4‐butanediol, to form a thermoplastic polyurethane containing 29% of the polycarbonate prepolymer. This polymer is intended for repeated use articles with short‐term contact (≤ 30 min) at room temperature for types of food, simulated by 10% ethanol and 3% acetic acid. In the third migration test performed at 40°C during 30 min, overall migration was below 2 mg/dm2. Complete migration of the residual dimethyl carbonate would have amounted to less than 1.5 μg/kg food. The migration of two cyclic hexanediol carbonate oligomers was below 50 μg/kg food when determined by the third migration test; that of all others was below 1 μg/kg food. Three in vitro genotoxicity studies performed in accordance with OECD Guidelines and covering the three endpoints gene mutation, structural and numerical aberrations were provided and were considered negative by the CEF Panel. The oligomers detected by the migration tests are formed from dimethyl carbonate and 1,6‐hexanediol (FCM ref No 1067) do not give rise to concern for genotoxicity. The CEF Panel concluded that the use of dimethyl carbonate does not raise safety concern in the application described above. It is aware that dimethyl carbonate may be used for other polycarbonates and/or under other conditions. These are likely to result in different migrates which need to be evaluated by the business operators. In such cases, the migration of dimethyl carbonate and the total polycarbonate oligomers below 1,000 Da is of no safety concern, if each of them does not exceed 0.05 mg/kg food.

International audience; his scientific opinion of the EFSA Panelon Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety assessment of the recycling process Krones pellet (EU register number RECYC0149). The input to the process is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers and containing no more than 5% PET from non-food consumer applications. In this technology, washed and dried PET flakes are extruded to pellets that are then crystallised and decontaminated in a reactor at high temperature under vacuum. Having examined the results of the challenge test provided, the Panelconcluded that two steps, the extrusion (step 2) and the decontamination in the vacuum reactor (step 4), are the critical steps that determine the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, residence time and, for the vacuum reactor, also pressure. Under these conditions, it was demonstrated that the recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 g/kg food. Therefore, the Panelconcluded that the recycled PET obtained from this process when used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET should not be used in microwave and conventional ovens.

The food enzyme considered in this opinion is a beta-amylase (EC 3.2.1.2), obtained from the grain of wheat (Triticum spp.) by Roquette (France). The beta-amylase is intended to be used in starch processing for production of glucose syrups containing maltose to be used as a food ingredient. Since the presence of residual amounts of total organic solids (TOS) in glucose syrups after filtration and purification during starch processing is negligible, no dietary exposure was calculated. As the food enzyme is derived from edible parts of wheat, no toxicological tests are required. Wheat is known as a gluten-containing cereal. However, the gluten content of the food enzyme was shown to be below the limit of quantification of the applied analytical method and well below the threshold value of 20 mg/kg for 'gluten-free' products. Furthermore, the potential allergenicity was evaluated by searching for similarity between the amino acid sequence of the beta-amylase and the sequences of known food allergens; no match was found. Although b-amylase from wheat is described as a potential occupational respiratory allergen, and oral wheat challenges in wheat allergic patients may result in clinical symptoms, the enzyme and the low levels of other wheat proteins will be removed from the final food ingredients through a downstream purification process. Based on the origin of the food enzyme from edible parts of grain, the manufacturing process, and the compositional and biochemical data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

International audience; The food enzyme considered in this opinion is a pullulanase (pullulan 6--glucanohydrolase; EC 3.2.1.41), produced with the genetically modified Bacillus subtilis strain NZYM-AK by Novozymes A/S (Denmark). The pullulanase food enzyme is intended to be used in starch processing for the production of glucose syrups. Since the residual amounts of total organic solids (TOS) in glucose syrups after filtration and purification during starch processing were considered negligible, no dietary exposure was calculated. Genotoxicity tests made with the food enzyme indicated no genotoxic concern. A repeated dose 90-day oral toxicity study in rodents, carried out with a pullulanase produced with a predecessor strain, showed no concern with respect to systemic toxicity. The allergenicity was evaluated by searching for similarity of the amino acid sequence to those of known allergens; no match was found. The Panelconsiders that there are no indications for allergic reactions. Based on the microbial source, genetic modifications performed, the manufacturing process, the compositional and biochemical data provided, the findings in the toxicological studies and allergenicity assessment, the Panelconcludes that this food enzyme does not give rise to safety concerns under the intended conditions of use.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids was requested to evaluate the genotoxic potential of one flavouring substance from subgroup 1.1.1(b) of FGE.19 in the Flavouring Group Evaluation 226 (FGE.226). The flavour industry provided genotoxicity studies for the substance 4,5‐epoxydec‐2(trans)‐enal [FL‐no: 16.071]. Based on these data, the Panel concluded in FGE.226 that 4,5‐epoxydec‐2(trans)‐enal did not induce gene mutations in bacterial cells but was positive in an in vitro micronucleus assay, so, 4,5‐epoxydec‐2(trans)‐enal is considered an in vitro genotoxic agent. The negative results obtained in an in vivo micronucleus assay cannot overrule the positive results of the in vitro micronucleus assay with and without S9‐mix due to the lack of demonstration of bone marrow exposure. Following this, the flavour industry has provided plasma analysis of a satellite group of rats treated with 4,5‐epoxydec‐2(trans)‐enal in order to investigate the systemic exposure of animals in the in vivo micronucleus assay. However, the plasma analysis did not provide enough evidence of target tissue exposure. An in vivo Comet assay in rodents was recommended in FGE.226, in order to investigate possible genotoxic effects at the first site of contact (e.g. stomach/duodenum cells) and in the liver. An in vivo Comet assay in liver and duodenum was provided that suggests that 4,5‐epoxydec‐2(trans)‐enal [FL‐no: 16.071] did not induce DNA damage in the duodenum of rats. However, the genotoxic effect observed in vitro was confirmed in the in vivo Comet assay in the liver of rats. The Panel concluded that 4,5‐epoxydec‐2(trans)‐enal [FL‐no: 16.071] does raise a safety concern with respect to genotoxicity and, therefore, it cannot be evaluated according to the Procedure.

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing aids (CEF Panel) deals with the safety assessment of 1,2,3,4‐tetrahydronaphthalene‐2,6‐dicarboxylic acid, dimethyl ester (TDCM) for use as a co‐monomer to manufacture polyester layers. The polyester layer is not intended to be in direct contact with food. The finished multilayer articles are intended for packaging aqueous, acidic and low alcoholic foodstuffs. Contact conditions include sterilisation followed by long‐term storage at room temperature. No thermal degradation of TDCM is expected during the manufacture of the middle polyester layer and of the multilayer articles. Total mass transfer of the substance from a polyester monolayer was calculated to be up to 0.032 mg/kg food. Based on three in vitro genotoxicity tests, the CEF Panel considered that the substance does not raise concern for genotoxicity. When tested behind a polypropylene layer, migrating TDCM‐related oligomers, their oxidation products and other related reaction products were identified. The major components were TDCM dimers. When tested behind a cyclo‐olefin polymer layer, none of the TDCM‐related substances were found to migrate. Based on the lack of genotoxicity of the co‐monomer, the ester nature of the oligomers and on (quantitative) structure–activity relationship ((Q)SAR) analysis, the CEF Panel considered that there is no indication of genotoxicity for the oligomers, their oxidation products and other TDCM‐related reaction products. The CEF Panel concluded that the substance is not of safety concern for the consumer if used as a co‐monomer for the manufacture of a polyester layer intended to be used as an inner (non‐food contact) layer of a multilayer material for contact with foods simulated by simulants A, B, C, D1 (as set in Regulation (EU) 10/2011). The migration of the sum of the substance and the dimers (cyclic and open chain) should not exceed 0.05 mg/kg food.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was requested to evaluate the genotoxic potential of flavouring substances from subgroup 2.2 of FGE.19 in the Flavouring Group Evaluation 208 Revision 2 (FGE.208Rev2). In FGE.208Rev1, the CEF Panel evaluated genotoxicity studies on p‐mentha‐1,8‐dien‐7‐al [FL‐no: 05.117], the representative substance for FGE.19 subgroup 2.2. The Comet assay performed in liver showed a positive result, and therefore, the Panel concluded that p‐mentha‐1,8‐dien‐7‐al [FL‐no: 05.117] is genotoxic in vivo and that, accordingly, there is a safety concern for its use as flavouring substance. Since p‐mentha‐1,8‐dien‐7‐al [FL‐no: 05.117] is representative for the nine remaining substances of subgroup 2.2 (p‐mentha‐1,8‐dien‐7‐ol [FL‐no: 02.060], myrtenol [FL‐no: 02.091], myrtenal [FL‐no: 05.106], 2,6,6‐trimethyl‐1‐cyclohexen‐1‐carboxaldehyde [FL‐no: 05.121], myrtenyl formate [FL‐no: 09.272], p‐mentha‐1,8‐dien‐7‐yl acetate [FL‐no: 09.278], myrtenyl acetate [FL‐no: 09.302], myrtenyl‐2‐methylbutyrate [FL‐no: 09.899] and myrtenyl‐3‐methylbutyrate [FL‐no: 09.900]), the Panel concluded in the previous revision of FGE.208 (FGE.208Rev1) that there is a potential safety concern for these substances. Subsequently, the industry has submitted genotoxicity studies on five substances of FGE.19 subgroup 2.2: p‐mentha‐1,8‐dien‐7‐ol [FL‐no: 02.060], myrtenol [FL‐no: 02.091], myrtenal [FL‐no: 05.106], p‐mentha‐1,8‐dien‐7‐yl acetate [FL‐no: 09.278] and myrtenyl acetate [FL‐no: 09.302], which are evaluated in the present revision of FGE.208 (FGE.208Rev2). The Panel concluded that the concern for genotoxicity could be ruled out for p‐mentha‐1,8‐dien‐7‐ol [FL‐no: 02.060], myrtenol [FL‐no: 02.091], p‐mentha‐1,8‐dien‐7‐yl acetate [FL‐no: 09.278] and myrtenyl acetate [FL‐no: 09.302], which will be evaluated through the Procedure. Genotoxicity data on myrtenal [FL‐no: 05.106] were considered equivocal, therefore, it cannot be evaluated through the Procedure, presently. p‐Mentha‐1,8‐dien‐7‐al [FL‐no: 05.117] and four substances not supported by industry (2,6,6‐trimethyl‐1‐cyclohexen‐1‐carboxaldehyde [FL‐no: 05.121], myrtenyl formate [FL‐no: 09.272], myrtenyl‐2‐methylbutyrate [FL‐no: 09.899] and myrtenyl‐3‐methylbutyrate [FL‐no: 09.900]) have been deleted from the Union List.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the recycling process Märkische Faser (EU register number RECYC0135), which is based on the Next Generation Group (NGR) technology. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% PET from non-food consumer applications. In this technology, post-consumer washed and dried PET flakes are melted and degassed in an extruder under vacuum (step 2) and decontaminated during a melt-state polycondensation under high temperature and vacuum (step 3). In step 4, the melt material is homogenised, extruded under vacuum and subsequently pelletised. Having examined the results of the challenge test provided, the Panel concluded that the steps 2, 3 and 4, are the critical steps for the decontamination efficiency of the process. The operating parameters which control the performance of these steps are well defined and are the temperature and pressure in all steps and the exposed surface area of the melt and its residence time of step 3. It was demonstrated that the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 μg/kg food. The Panel concluded that recycled PET obtained from the process Märkische Faser is not of safety concern when used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature. Thermoforming trays are not intended to be used and should not be used in microwave and conventional ovens.

International audience; This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the EREMA recycling process (the EREMA Multi-Purpose Reactor (MPR), EREMA Basic and EREMA Advanced technologies), with EU register number RECYC0134. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% PET from non-food consumer applications. In the MPR technology, post-consumer washed and dried PET flakes are heated in a continuous reactor under vacuum. The EREMA MPR decontamination technology can be combined with an extrusion line for pellets or sheet (EREMA Basic) or with an additional reactor (EREMA Advanced). The decontamination efficiency of the main continuous reactor (EREMA MPR technology) was determined by the challenge test. The Panel noted that this reactor is the critical step that determines the decontamination efficiency of these three EREMA technologies. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 mu g/kg food, derived from the exposure scenario for infants, and 0.15 mu g/kg food, derived from the exposure scenario for toddlers, when recycled PET is used at up to 100%. The Panel concluded that recycled PET obtained from the process is not of safety concern when used to manufacture articles intended for food contact applications if it is produced in compliance with the conditions and the percentage of recycled PET added to virgin PET specified in this opinion.

The food enzyme considered in this opinion is an endo‐1,4‐β‐xylanase (EC 3.2.1.8) produced with a genetically modified strain of Aspergillus niger. The genetic modifications do not give rise to safety concerns. The food enzyme contains neither the production organism nor recombinant DNA. The endo‐1,4‐β‐xylanase is intended to be used in baking processes. Based on the maximum use levels recommended for the respective food process, dietary exposure to the food enzyme–total organic solids (TOS) was estimated on the basis of individual data from the EFSA Comprehensive European Food Consumption Database. This exposure estimate is below 0.013 mg TOS/kg body weight (bw) per day in European populations. No safety concerns were identified in relation to the genetic modifications performed, the manufacturing process, the compositional and biochemical data provided, allergenicity and exposure assessments. The allergenicity was evaluated by comparing the amino acid sequence to those of known allergens; no match was found. The Panel considered that the likelihood of allergic reactions to dietary intake of endo‐1,4‐β‐xylanase is low and, therefore, does not give rise to safety concerns. The systemic toxicity was assessed by means of a repeated dose 90‐day oral toxicity study in rodents. A no observed adverse effect level was derived (4,095 and 4,457 mg TOS/kg bw per day for males and females, respectively), which, compared with the dietary exposure, results in a sufficiently high margin of exposure. However, the genotoxicity data were incomplete. Due to the absence of the recommended combination of microbial strains used in the Ames test (i.e. lack of Salmonella Typhimurium TA102 and Escherichia coli WP2), no conclusions can be drawn on potential DNA oxidising or cross‐linking mechanisms giving rise to gene mutations. Consequently, no final conclusions can be drawn on genotoxicity.

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was requested to deliver a scientific opinion on the implications for human health of the flavouring substance 4‐amino‐5‐(3‐(isopropylamino)‐2,2‐dimethyl‐3‐oxopropoxy)‐2‐methylquinoline‐3‐carboxylic acid [FL‐no: 16.130], in the Flavouring Group Evaluation 407 (FGE.407), according to Regulation (EC) No 1331/2008 of the European Parliament and of the Council. The substance has not been reported to occur in natural source materials of botanical or animal origin. It is intended to be used as both the parent compound and its hemisulfate monohydrate salt as a flavouring substance with modifying properties in specific categories of food. The chronic dietary exposure to the substance estimated using the added portions exposure technique (APET), is calculated to be 882 μg/person per day for a 60‐kg adult and 547 μg/person per day for a 15‐kg 3‐year‐old child. There is no concern with respect to genotoxicity. A 90‐day dietary administration study in rats showed no adverse effects for doses up to 100 mg/kg body weight (bw) per day, providing an adequate margin of safety. Developmental toxicity was not observed in a study with rats at the dose levels up to 1,000 mg/kg bw per day. The Panel concluded that [FL‐no: 16.130] and its hemisulfate monohydrate salt are not expected to be of safety concern at the estimated levels of dietary exposure calculated using the APET approach. This conclusion applies only to the use of the substance as a flavour modifier as requested and when used at the levels as specified for foods from different food categories.

Following a request from the European Commission, the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was requested to deliver a scientific opinion on the safety assessment of the flavouring substances caffeine [FL‐no: 16.016] and theobromine [FL‐no: 16.032] in the Flavouring Group Evaluation 49, Revision 1. Consequent to the 2015 scientific opinion from the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) on the safety of caffeine from all dietary sources, the CEF Panel considered it inappropriate to evaluate the two substances through the Procedure. For caffeine, the Panel based its assessment on the safety threshold of 5.7 mg/kg body weight (bw) per day for adults, except pregnant/lactating women, and 3 mg/kg bw per day for children, adolescents, pregnant and lactating women, as established by the NDA Panel. The safety evaluation of theobromine takes into account that approximately 11% of an oral dose of caffeine is metabolised to theobromine and that both substances have a similar pharmacological profile. For the exposure assessment, a brand loyalty model was chosen. In this model, it was assumed that a consumer is exposed on a long‐term basis to a specific category of food (i.e. non‐alcoholic beverages), containing caffeine or theobromine at their respective maximum use levels. For the rest of the categories, normal use levels applied. Daily dietary exposure to caffeine and theobromine (excluding systemic exposure) added as a chemically defined flavouring substance ranged 0–2.3 and 0–0.4 mg/kg bw, respectively, across all population groups. The Panel concluded that caffeine [FL‐no: 16.016] and theobromine [FL‐no: 16.032] would not be expected to present safety concern based on their estimated levels of intake from their use as flavouring substances.

International audience; The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the European Food Safety Authority was requested to evaluate 12 flavouring substances in Flavouring Group Evaluation 12, Revision 4 (FGE.12Rev4), including two additional substances, using the Procedure in Commission Regulation (EC) No 1565/2000. The present revision includes two additional flavouring substances: 12-beta-santalen-14-ol [FL-no: 02.216] and 12-alpha-santalen-14-ol [FL-no: 02.217]. None of the substances was considered to have genotoxic potential. The substances were evaluated through a stepwise approach (the Procedure) that integrates information on structure–activity relationships, intake from current uses and the toxicological threshold of concern and available data on metabolism and toxicity. The Panel concluded that none of the 12 substances [FL-nos: 02.134, 02.186, 02.216, 02.217, 05.157, 05.182, 05.183, 05.198, 08.135, 09.342, 09.670 and 09.829] gives rise to safety concerns at their levels of dietary intake, estimated on the basis of the maximised survey-derived daily intake approach. Besides the safety assessment of these flavouring substances, the specifications for the materials of commerce have also been considered. Specifications including complete purity criteria and identity for the materials of commerce have been provided for all 12 candidate substances

The EFSA Panel on Food Additives and Flavourings (FAF) provides a scientific opinion on the safety of buffered vinegar as a new food additive. Buffered vinegar is a liquid or dried product prepared by adding sodium/potassium hydroxides (E 524 to E 525) and sodium/potassium carbonates (E 500 to E 501) to vinegar, compliant with European Standard EN 13188:2000 and exclusively obtained from an agricultural source origin (except wood/cellulose). The primary constituents of buffered vinegar are acetic acid and its salts. No biological or toxicological data obtained with the proposed food additive were submitted by the applicant as part of the dossier as, following oral ingestion, buffered vinegar dissociates into the acetic anion and acetate a natural constituent of the diet, and of the human body for which extensive data on their biological effects exist and for which EFSA in 2013 has previously concluded that the establishment of an acceptable daily intake (ADI) is not considered necessary. At the proposed maximum/typical use levels, the mean exposure to buffered vinegar from its use as a food additive expressed as acetic acid equivalents ranged from 8.9 mg/kg body weight (bw) per day in infants to 280.3 mg/kg bw per day in children. The 95th percentile of exposure to buffered vinegar ranged from 27.9 mg/kg bw per day in infants to 1,078 mg/kg bw per day in toddlers. The Panel concluded that there is no safety concern for the use of buffered vinegar as a food additive at the proposed maximum/typical use levels. The Panel could not conclude on the safety for the proposed uses at quantum satis as Group I food additive since the resulting exposure could not be estimated.
