Hemp flour from Dacia Secuieni and Zenit varieties was added to bread in different proportions (5%, 10%, 15% and 20%) to improve its nutritional properties. The purpose of this paper was to present the advanced nutritional characteristics of these bread samples. The selected varieties of hemp, accepted for human consumption, met the requirements for the maximum accepted level of THC in seeds. The protein content of new products increased from 8.76 to 11.48%, lipids increased from 0.59 to 5.41%, mineral content from 1.33 to 1.62%, and fiber content from 1.17 to 5.84%. Elasticity and porosity decreased from 95.51 to 80% and 78.65 to 72.24%, respectively. K, Mg, Ca, P, Mn and Fe are the main mineral substances in bread with addition of hemp flour from the Dacia Secuieni and Zenit varieties. The total amount of unsaturated fatty acids in the bread samples with hemp flour ranged from 67.93 g/100 g and 69.82 g/100 g. Eight amino acids were identified, of which three were essential (lysine, phenylalanine, histidine). Lysine, the deficient amino acid in wheat bread, increased from 0.003 to 0.101 g/100 g. Sucrose and fructose decreased with the addition of hemp flour, and glucose has not been identified. The amount of yeasts and molds decreased in the first 3 days of storage. Regarding the textural profile, the best results were obtained for the samples with 5% addition. In conclusion, bread with the addition of hemp flour has been shown to have superior nutritional properties to wheat bread.

The advanced characterization of flour from hemp seeds (edible fruits of Cannabis sativa L.) from the Dacia Secuieni and Zenit varieties, compared to wheat flour, was studied in this research. The aim was to present the characterization of 2 varieties, out of the 70 accepted in Europe, for human consumption. The varieties selected from hemp meet the THC level requirement (0.3 or 0.2% of the dry weight of the reproductive part of the female flowering plant) in seeds. Hemp flour was obtained by grinding. The flour samples were evaluated for physicochemical parameters (moisture, crude protein, lipids, ash, crude fiber), the content of micro and macro elements, fatty acids, amino acids, and carbohydrates. The total proteins in hemp flour are found in larger quantities by over 35% compared to wheat flour, and the lipids reach the threshold of 28%. The amount of mineral substances exceeds 3% in hemp flour, and the fibers exceed 26%, compared to 0.61% for wheat flour. The predominant mineral substances were K, Ca, Mg, p, Fe, and Mn. The predominant fatty acids were the unsaturated ones, predominantly being linoleic acid, followed by oleic and gamma-linoleic acid. In the case of amino acids, the highest amount is found in glutamic acid for hemp flours. As for carbohydrates, sucrose is found in the largest amount, followed by glucose and fructose. In conclusion, hemp flours have superior non-traditional characteristics to wheat flour, being a potential raw material for fortifying food or using them as such, having beneficial effects of consumption on the proper functioning of the human body.

The study aimed at assessing effects of partial replacement (0–40%) of wheat flour with roasted flaxseed flour (RFSF) on the quality attributes of biscuits. Nutritional, antioxidative, volatile and sensory properties, as well as texture analysis and the contents of macroelements and microelement were studied. Increasing RFSF content in biscuits resulted in a significant increase (p &lt, 0.05) in protein (from 8.35% to 10.77%), fat (from 15.19% to 28.34%) and ash (from 1.23% to 2.60%) while the hardness and spread factor of the biscuits decreased with the increased level of roasted flaxseed flour. Moreover, the addition of 40% RFSF registered a positive influence on the fibre content of the final baked biscuits, increasing its value about 6.7-fold than in the control sample. Total phenolic content, antioxidant activity and biscuits’ aroma volatile profile increased their amounts with RFSF addition. The nutritional, textural and sensorial results of the present study demonstrated that 25% RFSF could be added in the biscuits manufacturing without affecting the biscuits aftertaste, offering promising healthy and nutritious alternative to consumers.

Lactobacillus plantarum ATCC 8014 was used to ferment quinoa flour, in order to evaluate its influence on the nutritional and rheological characteristics of both the sourdough and muffins. The quantification of carbohydrates and organic acids was carried out on a HPLC-RID system (high-performance liquid chromatography coupled with with refractive index detector), meanwhile HPLC-UV-VIS (high-performance liquid chromatography coupled with UV-VIS detector), AAS (Atomic absorption spectrophotometry), aluminum chloride colorimetric assay, Folin&ndash, Ciocalteu, and 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity (DPPH) methods were used to determine folic acid, minerals, flavonoids, total phenols, and radical scavenging activity, respectively. Two types of sourdough were used in this study: quinoa sourdough fermented with L. plantarum ATCC 8014 and quinoa sourdough spontaneous fermented. The first one influenced the chemical composition of muffins in terms of decreased content of carbohydrates, higher amounts of both organic acids and folic acid. Furthermore, higher amounts of flavonoids, total phenols and increased radical scavenging activity were recorded due to the use of Lactobacillus plantarum ATCC 8014 strain. These results indicate the positive effect of quinoa flour fermentation with the above strain and supports the use of controlled fermentation with lactic acid bacteria for the manufacturing of gluten free baked products.

Lactobacillus Spicheri DSM 15429 strain was used to ferment rice flour, aiming at exploiting its influence on the amino-acids, minerals, lactic acid, total phenols, and antioxidant activity of the rice sourdough and gluten-free muffins. Gluten-free muffins were prepared by using 15% rice sourdough fermented with the above strain of lactic acid bacteria and compared with rice spontaneous fermentation. Methods like LC-MS (Liquid chromatography&ndash, mass spectrometry), AA (atomic absorption), HPLC (High-performance liquid chromatography), Folin&ndash, Ciocalteu, and 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity (DPPH) were used to fulfill the aim of the study. The addition of rice sourdough fermented with LAB was reflected in the chemical composition of the final baked good, improving its amount on bioactive compounds such as amino acids, mineral bioavailability, total phenols, and antioxidant activity. Total phenols and antioxidant activity increased their amount by 70.53% and 73.70%, respectively, meanwhile, lactic acid, minerals, and amino-acids increased their values at least twice. Thus, rice fermented with Lactobacilus spicheri DSM 15429 strain could be a tool to further increase the nutritional value of gluten-free baked products.

Walnut oilcake is a low-cost by-product of the edible oil industry but at the same time it is a valuable source of dietary fiber, natural antioxidants, and polyunsaturated fatty acids. In the context of health-friendly confectionary food products and to reduce the production cost, the aim of this study was to investigate the effect of walnut oilcake by-product on the quality characteristics and volatile profile of modified macarons. For this purpose, GC-MS and ITEX/GC-MS techniques were used to obtain the fatty acids methyl esters and the volatile profiles, physicochemical analyzes were performed to determine the nutritional characteristics and a nine-point hedonic scale test was performed for the sensory characteristics. The substitution of almond flour with 0%, 10%, 25% and 50% walnut oilcake powder increased the fiber, total phenolic content, and antioxidant capacity. Hedonic scores of the macaron samples made with different percentage of walnut oilcake decreased to additions of over 10%. Moreover, this result is emphasized by Pearson&rsquo, s correlation parameters indicating as optimal addition for modified macarons, percentages up to 10% of walnut oilcake. This approach could reduce the costs related to the acquisition of the ingredients due to the oilcake price which is 3% of the almonds flour price.

Gluten free products available on the market have a low textural quality associated with high crumbly structure, low-flavor, aroma, poor mouthfeel, less appearance, in comparison with the conventional final baked products. The aim of this study was to assess the influence of rice sourdough fermented with Lactobacillus spicheri DSM 15429 strain on textural, volatile profile, and sensorial properties of gluten free muffins in order to obtain baked goods with improved quality characteristics. Lactobacillus spicheri is a novel strain isolated from industrial rice sourdough but unexploited for bakery products manufacturing. The results showed that Lactobacillus spicheri DSM 15429 was able to growth in the rice flour influencing the texture and the volatile profile of gluten free muffins as well as their sensory characteristics. Both, textural parameters and volatiles recorded significant differences comparing to muffins obtained with a spontaneously fermented rice sourdough. Hardness and cohesiveness decreased while springiness and resilience of gluten free muffins improved their values. The volatile profile of gluten free muffins was significantly improved by utilization of the rice sourdough fermented with Lactobacilus spicheri DSM 15429. 3-methylbutanal, 2-methylbutanal, acetophenone and limonene were the main volatile derivatives responsible for aroma and odor scores of sensory analysis.

The aim of this investigation was to incorporate mustard flour into bread in order to improve its quality. For this purpose, wheat flour 650 type for bread making was replaced with mustard seed flour at the level of 5, 7 and 10%. Bread quality through physico-chemical and sensory characteristics was analyzed and compared to those of bread without mustard flour. The protein content of mustard flour bread increased with 5.03% as a result of mustard flour incorporation, coupled with an increase in ash content. Sensory evaluation results revealed that the sample containing 7% mustard flour scored highest in most of the attributes including overall acceptability. The study reveals that incorporation of 7% mustard flour gave desirable results in terms of phisyco-chemical and sensory caracteristics of mustard flour fortified bread.

Tonic wines are true natural elixirs, having the property to fortify the organism. To achieve a complex product and to supplement the antioxidant properties of the wine, the hawthorn fruits were added. They completed the product by maceration, so that the tonic wine got major active substances which have great medicinal value being effective in treating cardiovascular diseases. The content of polyphenols of tonic wine is about six times higher than in simple wine, the hawthorn representing a product rich in polyphenols (510.2 mg GAE/100g). Antioxidant capacity increased when hawthorn fruits were added, as they have an important contribution in terms of new product antioxidant properties. Hawthorn, honey and rosemary added extra minerals in the total dry extract. The relative density increased due to the substances present in hawthorn. The concentration of alcohol slightly increased due to the fermentation which triggers during maceration. The acidity of the new tonic wine developed here was higher, as compared to the simple wine. Higher acidity also contributed to the palatability, the new tonic wine showing a pleasant refreshing taste.

BACKGROUND The aim of this study was to investigate the influence of different packaging materials on storage stability of flavoured phytosterol-enriched drinking yogurts. White vanilla (WV) and blood orange (BO) phytosterol-enriched drinking yogurts conditioned in mono-layer and triple-layer co-extruded plastic bottles were stored at +6 ± 1 °C for 35 days (under alternating 12 h light and 12 h darkness) to simulate shelf-life conditions. Samples were collected at three different storage times and subjected to determination of total sterol content (TSC), peroxide value (PV) and thiobarbituric acid reactive substances (TBARs). RESULTS TSC was not significantly affected by packaging material or storage time and met the quantity declared on the label. PV was significantly influenced by yogurt type × packaging material × storage time interaction and TBARs by packaging material × storage time interaction. CONCLUSION Between the two packaging materials, the triple-layer plastic mini bottle with black coloured and completely opaque intermediate layer offered the best protection against lipid oxidation. © 2015 Society of Chemical Industry

Sunflower tahini faces quality problems due to the tendency of oil to exudate, causing accelerated rancidity and low marketability. In this study, the colloidal and oxidative stability of different trimodal particle size distributions of sunflower tahini (cumulative volume percentages of small, middle and large class populations of 9.61–16.67, 43.03–55.03 and 47.36–28.3) was evaluated during storage at three different temperatures. Decreasing sample particle size decreased the sunflower tahini colloidal stability. The coarsest prototype, being the most stable tahini in terms of oil separation, was included in the oxidative stability storage test together with a commercial tahini. The peroxide values of the studied sunflower tahini samples increased significantly (p

Apples produce volatile chemicals that are responsible for the characteristic flavour of the fruit, as well as for the attribute of the final flavour. The aroma induced by the volatile compounds is important in determining the quality of the fruit, and especially for determining consumer acceptability. Fruits from three apple varieties were analysed (Ionathan, Golden Delicious and Starkrimson) at technological maturity and consumption maturity. The analysis method was developed on a Shimadzu QP-2010 GC-MS gas chromatograph, equipped with an AOC - 5000 (CombiPAL) autosampler. The results showed that there are differences between varieties in terms of number, type and concentration of volatile compounds. Fruits at technological maturity have a high content of aldehydes while fruits at consumption maturity have a higher content of esters.

The aim of this study was to evaluate the level of thiobarbituric acid reactive substances (TBARs) in flavored phytosterol-enriched drinking yogurts during storage, with particular attention to matrix interference. Two phytosterol-enriched drinking yogurts (with white vanilla- WV and blood orange-BO) were kept under controlled conditions (16 h light at 25 °C/8 h dark at 15 °C) for 64 h. During the TBARs assay, a yellow complex was formed. The UV–Vis spectra showed two absorption bands around 450 and 530 nm, respectively. In both flavored phytosterol enriched drinking yogurts, the more intense absorption was around 450 nm. In conclusion, the development of TBA adducts leads to a higher overestimation of TBARs at 450 nm. The study of TBA reaction with some of the matrix compounds shows that propanal, pentanal, hexanal, p-anisaldehyde, and vanillin favor TBARs450 formation. Instead, acetaldehyde, nonanal, lactose, decanal, t-cinnamaldehyde, octanal, limonene, and lactic acid favor TBARs530 formation. The interference of volatile compounds in the TBARs assay is much higher in BO.

Two types of flavoured malt vinegar were obtained, one of them with turmeric and the other one with rosemary, pepper and grain mustard. In order to characterize the new products, several physicochemical analyses were conducted (antioxidant capacity, total extract and acidity).

The effect of sunflower seed flour supplementation on the quality characteristics of wheat flour cracker biscuits was studied. For this purpose, four experimental variants obtained by substituting wheat flour with different proportions (0%, 15%, 25%, and 35%) of sunflower seed flour, were used. The cracker biscuits with sunflower seed flour and the control samples were subjected to physico-chemical and organoleptic analyses. The cracker biscuits, prepared with sunflower seed flour up to a 35% level of supplementation in wheat flour, were found to be acceptable with respect to all sensory attributes. In the present study, significant improvement in the chemical composition (ash, fat, and crude protein) of wheat-flour cracker biscuits supplemented with sunflower seed flour was observed. This reflects the potential for use of sunflower seed flour, as a partial replacement for wheat flour, for enhancement of these nutrients/chemical constituents

This review aims to provide an overview of the current European Union (EU) legislation on novel foods and novel foods ingredients. A brief presentation of Regulation (EC) No 258/97 of the European Parliament and of the Council of 27 January 1997 concerning novel foods and novel food ingredients was attempted: the scope of the Regulation-the foodstuffs that apply/not apply of this Regulation-, the conditions for marketing, the application procedure and the labelling requirements.

Halva is one of the most popular food products of Middle Eastern and North African countries. Worldwide, the most known halva contains roasted sesame seeds, while usually in Eastern European countries the most appreciated is sunflower halva. However, even if sunflower halva is an appreciated product, it has currently a quality below the expectations of the new generation of consumers. Sunflower halva main issue is caused by the oil which separates at the surface during storage, determining a low commercial aspect of the product. Thus, the aim of this work was to assess the influence of palm oil addition on sunflower halva stability and texture. Five samples containing different oil percentages [w/w] (1%, 2%, 3%, 4%, 5%) were prepared, as well as a control sample prepared using the standard recipe (no palm oil added). The texture of all samples was analyzed by an instrumental method, while the colloidal stability was determined by a gravimetric technique during 40 days of storage at two different temperatures (1-2ºC and 15-20ºC). After the storage test at 1-2oC, there were not significant differences between the samples, for all palm oil containing samples as well as for control the percentages of separated oil being below 0.6%. With respect to the control sample, the halva samples containing 1%, 4% and 5% of palm oil showed a decrease in their stability, while samples containing 2% and 3% showed an improved stability (3.44% and 1.78% of separated oil). During this study it was established that the sample containing 3% palm oil was the most favorable, regarding its textural properties, as well as its colloidal stability.

Acrylamide is a colorless (or white), odorless, highly water soluble vinyl monomer formed from the hydration of acrylonitrile. The chemical compound acrylamide is an amide with chemical formula C3H5NO and structure. Acrylamide is a white odorless crystalline, soluble in water, ethanol and ether. It is used in papermaking, ore processing, manufacture of permanent-press fabrics, and the manufacture of dyes. Acrylamide is also used to synthesize polyacrylamides which find many uses as water-soluble stabilizers, for instance in waste water treatment and in gel electrophoresis (SDS-PAGE). Acrylamide is also a probable carcinogen found in small quantities in some foods. It is believed to be created in foods when starches and other carbohydrates are overheated (far past 100°C) during cooking. Some sources claim that people in the modern world consume daily on average around 25 micrograms of acrylamide, and that this accounts for a significant number of cases of cancer.

This paper aims to present the researches carried on the buckwheat (Fagopyrum sagittatum Gilib., sin.Fagopyrum esculentum Monich. Based on the nutritional value relatively close to the other cereal beans used in man`s nourishment, the buckwheat grains are on the future raw materials for the production of expanded cereals in the food industry. The research has been performed on the buckwheat of local population, of the crop of the year 2001 by achieving the most adequate physical parameters for expanding: roasting time (factor A), steam pressure (factor B) and steam impregnation time (factor C). For the assessment of the factors influence throughout several graduations, we have used the EVOP statistical processing method and variance method. The best outcomes whereby the grain volume has increased by 10,25 times, have been obtained when combining the factors: A = 12 min., B = 10 atm., C = 3 min.

In recent years, world grain production faces with disastrous effects induced several toxicogene species of the Fusarium, Alternaria, Aspergillus si Penicillium genera. Food and Agriculture Organization (FAO) estimated that worldwide up to 25% of food crops are significantly contaminated by mycotoxins. The most important mycotoxins that pose a significant hazard to human health are synthesized by molds that grow on grains, especially wheat and maize, but also barley, oats and rice. Practice has shown that the storage of grain, grist products and bakery product appears under certain conditions a microflora which favors the growth of fungi and production of mycotoxins.The existing molds in grain storage are multiply when the relative air humidity is between 80-85%, and the temperature reaches above 26° C. The products appeal to turn the source of infection, accumulating toxins. Aflatoxins have been highlighted in bread, cereal, maize, and some types of bread diet. In grain near afltatoxine was discovered and ochratoxin A and other toxic metabolites of fungi, most of the genera Aspergillus and Penicillium, which passing in grist products, highest concentrations are recorded in the bran. And the flour stored in conditions of high humidity may occur fungi producing mycotoxins (Fusarium, Mucor, Penicillium, Aspergillus). The growth control of fungi and production of mycotoxins in grain production can be achieved by: monitoring of storage conditions, use of antifungal agents, use of natural factors of resistance. So, it is recommended to store grain at low temperature and humidity as to optimal. By increasing of CO2 concentration in the atmosphere by storing up to 40%, production of mycotoxins is minimized. Consumption of food contaminated with certain types of molds can cause human and animal health adversely, the emergence of forms of "exudative hepatitis" by the presence of liver cancer. Most mycotoxins have carcinogenic effects.
