The typicity of wines is related to their sensory characteristics, which allow them to be differentiated from other wines. Different sensory methods have been applied to try to detect the sensory characteristics responsible for the typicity of Protected Designation of Origin wines (PDO). However, so far, none of them has been completely successful. In this study, a new one-step method based on free profile and comparative analysis by pairs was applied to generate sensory descriptors of wines. The discriminant power of the sensory attributes generated among wines from 4 different PDO wines from the Spanish Autonomous Community of Castilla y León was evaluated. The study was carried out with wine experts and 159 white, rosé, and red wines were tasted. The judges generated 245 attributes which were reduced to 95 (11 defects, 20 visual, 48 olfactory and 16 taste and mouthfeel). A Multifactorial Analysis was carried out with the data of contingency matrices based on the frequency of citation. The results obtained showed that the sensory descriptors generated allowed the wines to be distinguished according to their origin, being the discriminant power significantly higher when the visual, olfactory and gustatory attributes were considered separately. • A new method to generate sensory attributes has been developed. • The method is based on free profile and comparative analysis by pairs. • The sensory attributes generated allowed to differentiate wines by their origin. • The method proposed can be used by Councils to stablish the typicity of their wines.

Red arils, derived from the yew tree (Taxus spp.), are renowned for their edible and nutritional properties. In this study, a novel red aril (RA) wine was produced and evaluated for its quality characteristics and sensory attributes. The flavor compounds in RA wine changed dynamically during fermentation, with a total of 26 differential volatiles identified. PLSR analysis indicated that ketones positively contributed to the citrus odor. Furthermore, RA wine exhibited high levels of organic acids, polyphenols, and amino acids after fermentation, influencing its bitterness and sourness profile. Molecular docking revealed that the activation of receptor OR1G1 by 6-methyl-5-hepten-2-one, a key ketone volatile, generated the citrus odor in RA wine. Furthermore, the taste profile of RA wine was inclined towards bitterness and sourness. Molecular docking analysis also demonstrated interactions between the key differential taste compounds with bitter-taste receptor TAS2R14 and sour-taste receptor OTOP1. Moreover, an intricate metabolic profile of RA wine was revealed through an overall metabolic map, providing insights into the underlying formation mechanisms contributing to RA wine quality. • A novel red aril (RA) wine was produced and its quality was characterized. • Ketones, particularly 6-methyl-5-hepten-2-one, elevated citrus aroma in RA wine. • Flavor compound-receptor docking revealed RA wine flavor formation mechanisms. • The characteristic metabolic profile during fermentation of RA wine was elucidated.

Beetroot is a tuber rich in antioxidant compounds, i.e., betanin and saponins, and is one of the main sources of dietary nitrate. The aim of the present study was to microencapsulate a ready-to-eat beetroot soup by lyophilization using different encapsulating agents, which supply the required amount of bioactive nutrients. Particle size distributions ranged from 7.94 ± 1.74 to 245.66 ± 2.31 µm for beetroot soup in starch and from 30.56 ± 1.66 to 636.34 ± 2.04 µm in maltodextrin. Microparticle yields of powdered beetroot soup in starch varied from 77.68% to 88.91%, and in maltodextrin from 75.01% to 80.25%. The NO3− and total betalain contents at a 1:2 ratio were 10.46 ± 0.22 mmol·100 g−1 fresh weight basis and 219.7 ± 4.92 mg·g−1 in starch powdered beetroot soup and 8.43 ± 0.09 mmol·100 g−1 fresh weight basis and 223.9 ± 4.21 mg·g−1 in maltodextrin powdered beetroot soup. Six distinct minerals were identified and quantified in beetroot soups, namely Na, K, Mg, Mn, Zn and P. Beetroot soup microencapsulated in starch or maltodextrin complied with microbiological quality guidelines for consumption, with good acceptance and purchase intention throughout 90 days of storage. Microencapsulated beetroot soup may, thus, comprise a novel attractive strategy to offer high contents of bioaccessible dietary nitrate and antioxidant compounds that may aid in the improvement of vascular-protective effects.

A participatory cowpea varietal selection was carried out in Eastern Uganda in Kumi district among farmers (n=30) in the sub-Counties of: Ongino, Kumi and Kanyum. A range of opinions were collected to identify farmers’ selection criteria based on different sensory attributes and their most preferred genotypes for vegetable use. A preference analysis was carried out to obtain quantitative preference scores of each plot. This was followed by organoleptic tests which included attributes like taste, aroma and texture of the genotypes at the vegetative and immature R4 stages. Focus group discussions (FGDs) were also held to find consensus of the independent evaluations made by individual farmers. Data for sixteen (16) cowpea genotypes were collected at the different above mentioned stages. Quantitative data were analyzed based on farmers’ scores made on the different evaluated attributes and ANOVA was used to provide mean differences between location, gender and genotype at a significant level of 5%. Preference score for each of the varieties tested was determined and presented. Data from FGDs were grouped, similarities and differences were later determined depending on their level of importance to the farmers. Significant differences (p<0.05) in farmer choices were observed for leaf taste, immature pod aroma, taste and texture; mature pod aroma, taste between farmer groups, age genotype and gender. Irrespective of age, gender, farmer group and genotype, farmers seemed to give more importance to the smooth texture, little hard leaves when chewing, sweet taste with a mild aroma (leaves) and a moderate aroma (pods). Majority (9%) of the farmers preferred Ebelat (landrace) at V4 stage; this was followed by Danila (8.7%). On the other hand, UCUCOW1 (13% at immature and 10.2% at mature cooked R4 stage) followed by Ebelat (9% and 9.8% for immature and mature R4 stage, respectively) were preferred by majority of the farmers. In terms of sensory attributes, farmers preferred genotypes with sweet taste, moderate aroma and tender texture. The information is a baseline for understanding key farmer selection criteria in utilization of cowpea as a vegetable which can be used in generating a demand-led variety design for the crop.

Formulation of foods from –low‐lysine cereals fortified with animal protein is a potentially sustainable approach to enhance protein quality in diet due to nutritional compensation while buns are valuable vehicles to deliver nutrients to human body because of their relatively noble eating quality and extended shelf life. The aim of this study was to evaluate the sensory attributes and consumer acceptability of sorghum‐wheat buns containing snail meat powder (SMP). Buns were prepared by replacing 5, 10, 15, 20, and 25% of sorghum‐wheat composite flour with SMP. Principal component analysis (PCA) revealed 99% total variation of 23 attributes for buns scored by a descriptive sensory panel, of which 98% was due to the proportion of SMP that replaced sorghum‐wheat composite flour in buns and the remainder 1% was due to the buns' physical appearance. Compositing sorghum‐wheat buns with SMP imparted positive consumer attributes of fine crumb, sponginess, and crumby texture. It also resulted in buns with reasonably high sensory acceptability as evaluated by 8‐ to 9‐year‐old school children. The buns can serve as supplementary rich sources of protein for alleviating the menace of protein energy malnutrition in sub‐Saharan Africa. [ABSTRACT FROM AUTHOR]

The Mediterranean fruit fly (Ceratitis capitata) is one of the major problems in the citrus producing and trading countries including Turkey. Commercial application of radiation processing can be the alternative and effective solution to overcome this problem. The objective of the present study was the determination of the sensory attributes, quality parameters and also cold storage shelf-life of ‘Jaffa’ oranges (Citrus sinensis (L) Osbeck) irradiated (0, 0.5, 1.0 and 1.5 kGy) as considering postharvest quarantine treatment for the Mediterranean fruit fly (Ceratitis capitata). The quality parameters of the control and irradiated oranges were determined in terms of weight loss, pH, titratable acidity, total soluble solids, reducing sugars, vitamin C content, total carotenoids, pectin, color of fruit during cold storage at 4 ± 0.1 oC and 85 - 90 % relative humidity (RH) on the 0, 15, 30 and 45 d of storage. Obtained results showed that, low dose irradiation is applicable regarding other significant quality parameters of ‘Jaffa’ oranges such as vitamin C, total carotenoids, invert sugars, pectin, weight loss, pH, acidity and total soluble solids did not affect consumption and commercial value of ‘Jaffa’ sweet oranges up to 45 d of storage at 4 oC. According to overall sensory attributes, irradiated fruit was still acceptable as judged by panelists and ≤1.0 kGy irradiation dose more suitable for keeping important attributes of processed ‘Jaffa’ orange fruit.

Studies on emotions linked to sensory characteristics to understand consumers' choice behaviour have grown in number rapidly. Internal consumer behaviour variables, namely mood, familiarity, acceptability, and attitude (MFAA), have been found to influence emotional response. The aim of this paper was to determine the impact of MFAA on consumers' emotional responses towards chocolate as well as the effect of the sensory characteristics of chocolate on consumers' emotional responses. Upon ethical approval, three chocolates were selected by a trained sensory panel based on 14 sensory attributes regarded relevant. Screened respondents (n = 149) completed an online survey based on the tasting of the chocolates by means of a home-use test (HUT). The questionnaire captured consumers' mood (Quick mood scale), familiarity (QFFQ), acceptability (FACT), the sensory characteristics of the chocolate samples and emotional response (EsSense25 Profile), and lastly attitude (ACQ). Descriptive and inferential statistics were examined to answer the hypotheses of the study. The findings indicate that emotions are related to the bitter sensory attributes of chocolate and that this emotional response is influenced by MFAA variables, supporting the known fact that consumer behaviour is complex and multi-dimensional. Internal consumer behaviour variables play an important role in the emotions experienced during the consumption of chocolate. Investigating the relative importance of consumer behaviour components in sensory studies could allow for the design of food products such as chocolates based on a more "holistic" view of the consumer.

The effect of Origanum syriacum L. essential oil (OE) on lipid oxidation, total volatiles, and sensory evaluation of cooked chicken meat was investigated. The treatments applied were 1) Control; 2) 200 ppm oregano essential oil (OEL1); 3) 250 ppm (OEL2); 4) 150 ppm sodium nitrite (E-250); and 5) 14 ppm butylated hydroxyanisole (BHA) mixed with ground chicken thigh meat. The raw meat was cooked, stored under refrigeration, and analyzed for lipid oxidation and total volatiles after 0, 4, and 8 days. In addition, cooked thigh meat patties were prepared separately for evaluation of specific sensory attributes. Generally, OEL2 was the most comparable additive to the synthetic E-250 regarding TBARS values. The total volatile (TV) profile showed that E-250 and OEL2 were the most effective at decreasing off odor volatiles (p < 0.05). Sensory data also revealed the greatest improvement in overall meat acceptability with the use of OEL2. The recommended level of OE in cooked chicken meat is approximately 250 ppm.

BACKGROUND: Maize tortillas are the staple food of Mexico and their consumption contributes to preserving the gastronomic patrimony and food security of the population. The aim of the present study was to generate a reference sensory profile for different types of tortillas and to evaluate the effect that these sensory characteristics have on consumer liking and how this influences their consumption preferences and purchase intent. Three types of maize tortillas were analyzed: traditional (T1), combined (T2) and industrialized (T3). The samples were characterized using the modified flash profile method. Sensory acceptability and preference tests were conducted on 240 urban and rural consumers. RESULTS: The judges characterized 19 attributes in the tortilla samples, eight of which were also identified by consumers. In the case of traditional tortillas, the matching attributes were maize flavor, color, thickness and moisture. Only rural consumers were able to perceive significant differences between the samples in terms of aroma and taste/flavor. The study has contributed to understanding the complex mechanisms of sensory acceptance through the use of tools that combine qualitative and quantitative data. CONCLUSION: Although 56% of rural and urban consumers prefer traditional tortillas for their sensory characteristics, purchase intent is also affected by socioeconomic, cultural and microbiological factors. © 2021 Society of Chemical Industry.

Honey consumption has started to increase in recent years in Romania, according to statistics. In this context, the main objective of the paper was to study consumer behaviour and sensory perception of honey by Romanian young segment. The research was based on blind sensory testing of two honey samples (one commercial sample with country of origin indicated as “Blend of EU and non-EU honeys” and one from a local Romanian beekeeper). The sensory analysis was complemented with a questionnaire survey. In total, 100 university students from Cluj region participated. The results showed that the majority of participants consume honey only occasionally and their annual consumption is lower than 1 kg. Honey is mostly used as sweetener in beverages (tea, lemonades). The most preferred type of honey is acacia, followed by linden honey. Sensory testing showed that young people perceived the quality of honey and their preference by using mostly the taste. In addition, interesting results were acquired by respondents which decision was based also on aroma. Almost 83% of them indicated preference for honey from Romanian beekeeper.

Hot Smoked Spiced Catfish (HSSC) samples prepared under optimal conditions (garlic, 7.29 g/100 ml; ginger, 7.50 g/100 ml; turmeric, 2.5 g/100 ml; soaking temperature, 38.68°C and soaking time, 7.51 min) were stored at ambient temperature (30±2°C) for a period of 20 days to evaluate storage stability; un-spiced hot smoked catfish served as control. Moisture Content (MC), Thiobarbutric Acid (TBA), Peroxide Value (PV), Free Fatty Acid (FFA), Total Viable Counts (TVC) and Mould Counts (MoC) were monitored at two-day intervals as a measure of the storage stability indices. Sensory attributes of the Optimized Hot Smoked Spiced Catfish (OHSSC), control (unspiced) and commercial hot-smoked catfish were determined using a preference test. The storage stability indices values for HSSC were in the range of 6.64 - 7.01% (MC), 4.50 - 13.77 mg MDA/kg (TBA), 0.20 - 2.84 mEq/kg (PV), 0.72 - 9.64% (FFA), 9.50 - 57.00 cfu/g (TVC), 8.00 - 34.50 cfu/g (MoC). The control sample values were in the range of 6.97 - 7.30% (MC), 5.51 - 14.92 mg MDA/kg (TBA), 0.23 to 2.86 mEq/kg (PV), 2.24 - 11.88% (FFA), 13.50 - 113.00 cfu/g (TVC), and 10.00 - 49.00 cfu/g(MoC). The sensory evaluation indicated that OHSSC was most preferred in all the evaluated sensory parameters. This study established the synergistic effects of garlic and turmeric on the keeping quality and sensory attributes of hot-smoked catfish with the prospect of reducing post harvest losses.

Background: An adequate dietary intake, especially of protein and energy, is important for maintaining health among elderly people, especially those in care homes. One strategy to ensure nutritional intake is to customise attractive products through enrichment to match the needs of elderly people in care homes. Objective: To evaluate liking and practical aspects of protein and energy enriched in-between meals designed for elderly people in care homes through the use of quantitative and qualitative assessments. Design: A broad range of energy and protein enriched in-between meals, including both savoury and sweet products, were included. The products were evaluated by a consumer test and a focus group discussion with elderly respondents. The products were also evaluated by a second focus group discussion with care staff. Results: The most liked products were ice cream and cheesecake. All products achieved high scores for appearance, taste/flavour and texture. No product included in the study was extremely disliked. However, the least liked product was tomato soup, which scored above the middle of the scale except for texture. It was clear from the focus group discussions that a colourful appearance, small portion size and texture were of primary importance. The temperature had an impact on liking and swallowability. Discussion: Most products were perceived by the elderly participants as appealing and tasting good, and possible to include in a daily diet. It was clear that the colours of the foods were of primary importance. In line with other studies, it was found that highly liked in-between meals were frozen, cold and sweet. These products were also easy to swallow. Conclusions: It is possible to produce highly liked energy and protein enriched in-between meal products designed for elderly people. The temperature had a great impact on the liking of texture, taste and flavour. In-between meals should preferably be colourful and have a small portion size.

Research background. It is desirable to increase the consumption of pelagic fish rich in long-chain omega-3 fatty acids. Partial replacement of traditionally used white fish species by pelagic fish will increase the content of omega-3 fatty acids, and thus improve the nutritional value but it may also affect the consumer acceptance. The aim of this study is to assess the physicochemical and sensory quality of novel fish cake prototypes prepared from haddock and mackerel mince. Experimental approach. Fillets of haddock and Atlantic mackerel were used as raw material for preparation of fish cakes. The fish fillets were minced, mixed together (in haddock/mackerel mass ratio of 100:0, 75:25 and 50:50%) with salt, potato starch, pepper and full fat milk. Physicochemical and sensory analyses were further performed. Results and conclusions. The fatty acid composition analysis showed that the recommended daily intake of 250 mg of eicosapentaenoic acid and docosahexaenoic acid can easily be reached by consumption of fish cakes enriched with mackerel. The oxidation levels of all fish cakes were low in terms of peroxide value and thiobarbituric acid reactive substance assay (TBARS). Fish cakes prepared with higher mass fraction of mackerel mince (>50%) had significantly (p50%) fish cakes due to higher myoglobin content in the fish muscle. Moreover, fish cakes with higher amount of mackerel mince had increased yellowness due to the accumulation of water-soluble (r=0.990, p

The influence of substituting sucrose with date palm fruit flour (DPFF) on the nutritional and sensory attributes in bread production was studied. Bread was baked in varying proportions of sucrose and date palm fruit flour as follows: (100% sucrose: 0% DPFF), (50% sucrose: 50% DPFF) and (0% sucrose: 100% DPFF). The results of proximate analysis showed that (100% sucrose: 0% DPFF) had 61.90% carbohydrate and fat (3.73%) contents significantly (p

Aging is one of the most important processes in the production of high-quality spirits, including whisky, brandy and cognac. The contact between wood and distillates is a crucial step for the migration of chemical compounds, which evoke the novel sensory properties of the final products. Novel taste is pleasurable for a vast group of consumers and depends on cultural preferences. In order to demystify the main chemical compounds for aroma contribution, connecting them with a sensory profile of aged spirits is a crucial step in hastening the very timeless process without decreasing the quality. Consumption patterns of spirit drinks have been influenced by changed consumers' preferences and increased availability of different types of spirits on the market. Consumers' choice of one type of spirit drinks over others is significantly shaped by extrinsic attributes and consumer-based factors, but the choice among different available options of the single type of spirit may be based on consumers' perception of its specific sensory attributes. Therefore, the combination of taste, aroma, color and other sensory attributes of a spirit drink can shape consumers' perceived quality of the spirit and impact the potential of its market success in general.

Whole grain flour is gaining an increase in demand for its nutritive and health promotion values in different food products for human consumption worldwide. Whole flour from wheat grain varieties (Gihundo, Kibatsi, Nyaruka and Reberaho), spent coffee grounds (SCG), juices of lemon fruit (L) and rosemary leaves (R), and dough fermentation were assessed for their impact on the texture profile, colour and sensory attributes of bread. Wheat grains (sampled from the stores of Rwanda Agriculture and Animal Resources Development Board, Kinigi, Rwanda) were conditioned to 15.5% moisture content and were wholly milled. The mixture of 200 g whole wheat flour, 4% spent coffee grounds, 1% juice of lemon fruit and 1% juice of rosemary leaves were fermented by using 2% instant dry yeast at 34 °C, 60% relative humidity (RH) for 60 min and at 39 °C, 85% RH for 120 min, separately. The dough was baked at 180 °C for 20 min. Data were subjected to one-way analysis of variance using SAS System. Treatment means were separated using Tukey’s test and the least significant difference was accepted at p ≤ 0.05. The control bread was made for 60 min of fermentation without incorporation of SCG and LR. The control bread was harder than the bread containing SCG and SCG+LR with the same time of fermentation. The long fermentation and the inclusion of SCG and SCG+LR in doughs, caused the supplemented bread to have lower L*, a* and b* values than control bread. Low L*, a* and b* values indicate minimum darkness, redness and yellowness of bread. Aroma, taste and appearance of SCG+LR bread from doughs fermented for 120 min were the most liked. Whole wheat bread obtained satisfied consumers’ preferences. Therefore, the application of spent coffee grounds, juices of lemon fruit and rosemary leaves in bread making represents a good opportunity at low cost.

The functional soup formulated with leaves of Solanum nigrum, an underutilized food crop, was studied for the comparison between two different types of sensory analysis to identify the sample with the most preferable sensory acceptability and to determine the sensory attribute that influences the overall acceptability of the product. Hedonic scale analysis and Fuzzy logic sensory analysis were performed on 11 combinations of formulated soup mix obtained by D-optimal mixture design. The hedonic and fuzzy logic analysis revealed that flavour and taste had higher contribution towards overall acceptability of the soup, based on hedonic sensory score and higher similarity index values. The consumers preferred these parameters primarily and these influenced towards the consumer acceptability of the product. Linear regression analysis and Pearson's correlation of the hedonic data expressed that flavour and taste had major influence and correlation to the overall acceptability. The soup samples with moderate levels of leaf powder (3%), starch (35%) and spice mix (62%) were found to be the most organoleptically acceptable hedonically amongst all 11 combinations with the highest hedonic sensory score of 6.4 but based on fuzzy analysis sample 3 of leaf powder (1%), starch (28%) and spice mix (68%) had higher similarity index of 0.92.

Hot Smoked Spiced Catfish (HSSC) samples prepared under optimal conditions (garlic, 7.29 g/100 ml; ginger, 7.50 g/100 ml; turmeric, 2.5 g/100 ml; soaking temperature, 38.68 °C and soaking time, 7.51 min) were stored at ambient temperature (30±2 °C) for a period of 20 days to evaluate storage stability; un-spiced hot smoked catfish served as control. Moisture Content (MC), Thiobarbutric Acid (TBA), Peroxide Value (PV), Free Fatty Acid (FFA), Total Viable Counts (TVC) and Mould Counts (MoC) were monitored at two-day intervals as a measure of the storage stability indices. Sensory attributes of the Optimized Hot Smoked Spiced Catfish (OHSSC), control (unspiced) and commercial hot-smoked catfish were determined using a preference test. The storage stability indices values for HSSC were in the range of 6.64 - 7.01% (MC), 4.50 - 13.77 mg MDA/kg (TBA), 0.20 - 2.84 mEq/kg (PV), 0.72 - 9.64% (FFA), 9.50 - 57.00 cfu/g (TVC), 8.00 - 34.50 cfu/g (MoC). The control sample values were in the range of 6.97 - 7.30% (MC), 5.51 - 14.92 mg MDA/kg (TBA), 0.23 to 2.86 mEq/kg (PV), 2.24 - 11.88% (FFA), 13.50 - 113.00 cfu/g (TVC), and 10.00 - 49.00 cfu/g(MoC). The sensory evaluation indicated that OHSSC was most preferred in all the evaluated sensory parameters. This study established the synergistic effects of garlic and turmeric on the keeping quality and sensory attributes of hot-smoked catfish with the prospect of reducing post harvest losses.

This study was aimed to use extrusion cooking as a pretreatment for non-conventional seeds (Indian horse chestnut flour) to blend them with whole grain flours (whole wheat flour, whole barley flour, and whole corn flour) for the development of a pregelatinized cereal bar (PCB). In this study, date paste (7.5–17.5%) and walnut grits (2.5–12.5%) were incorporated at varying levels to prepare PCB. The PCB was evaluated for its nutritional, color, textural (both three-point bending test and TPA), antioxidant activity, and sensory attributes. The flexural modulus, rupture stress, and fracture strain of PCB increased with the incorporation of a higher proportion of date paste. The protein and fiber content in PCB increased from 7.74 to 9.13% and 4.81 to 5.59% with the incorporation of walnut grits and date paste, respectively. The DPPH, total phenolic content, and water activity of PCB were determined, which progressively enhanced with increased levels of walnut grits and date paste. The correlation between sensory attributes and instrumental texture on PCB was also investigated. The correlation results showed a significant (p < 0.05) positive correlation between texture analysis and sensory hardness, springiness, adhesiveness, and negatively correlated to instrumental and sensory cohesiveness. For sensorial attributes, all PCB samples presented average scores of 7/10 and 4/5 for buying intention. Therefore, whole grain extrudates, date paste, and walnut grits can be efficiently used to develop PCB with improved nutritional, nutraceutical, and economic values.

The original Coffee Taster's Flavor Wheel was developed by the Specialty Coffee Assn. of America over 20 y ago, and needed an innovative revision. This study used a novel application of traditional sensory and statistical methods in order to reorganize the new coffee Sensory Lexicon developed by World Coffee Research and Kansas State Univ. into scientifically valid clusters and levels to prepare a new, updated flavor wheel. Seventy-two experts participated in a modified online rapid free sorting activity (no tasting) to sort flavor attributes of the lexicon. The data from all participants were compiled and agglomeration hierarchical clustering was used to determine the clusters and levels of the flavor attributes, while multidimensional scaling was used to determine the positioning of the clusters around the Coffee Taster's Flavor Wheel. This resulted in a new flavor wheel for the coffee industry.

Olives treated according to the Spanish-style are firstly treated with caustic soda and then fermented in brine to reduce phenols. Next, olives are packed and subjected to pasteurization. The effect of different high hydrostatic pressure treatments (400 MPa, 4 and 6 min) was evaluated in Spanish-style table olives fermented with olive leaf extract (OLE) and S. cerevisiae compared with thermal pasteurization (P) at 80 °C for 15 min. HHP and P led to a significant reduction in yeast and aerobic mesophiles after the conservation treatment and during storage (300 days). The physical–chemical properties changed slightly during storage, except for olive hardness; olives treated with HHP presented a higher hardness than pasteurized ones. The CIELAB parameter L* decreased until day 300 in most of the treatments, as well as phenols. The HHP treatment led to significantly higher contents of phenolics (even during storage) than olives submitted to P. Some sensory attributes (colour, aspect, hardness, and overall evaluation) decreased during storage. P treatment caused a decrease in appearance, aroma, hardness, and overall evaluation compared to olives treated with HHP. Thus, the application of HHP in table olives to increase the shelf-life can be considered a valid alternative to P. [ABSTRACT FROM AUTHOR]

Background: Enzyme injection is vital for improving the sensory attributes and processing characteristics of meat products by enhancing proteolysis. However, studies regarding the appropriate dose addition for accelerating protein degradation in grass carp are minimal. This study aimed to investigate the impact of Flavourzyme® on the flavor quality and antioxidant activity of salted grass carp via brine injection and brining. Results: Flavourzyme was added at doses of 0, 5, 10, 20, and 30 leucine aminopeptidase units (LAPU) per kilogram of raw meat. The results indicated that adding Flavourzyme promoted proteolysis, which was reflected by the enhanced total free amino acid content (from 3.7414 g kg−1 to 4.9160 g kg−1 in the brining group and from 3.8039 g kg−1 to 5.4061 g kg−1 in the injection group) and a decrease in salt soluble and insoluble protein (P < 0.05). The antioxidant activity was improved, and the thiobarbituric acid reactive substance value in salted carp decreased due to the higher content of the protein hydrolysis product (P < 0.05). All sensory attributes were improved significantly, especially when using brine injection (P < 0.05). Brine injection was helpful to diffuse the Flavourzyme, resulting in stronger proteolysis. Conclusion: The appropriate Flavourzyme dose was 10 LAPU kg−1 in the injection group and 20 LAPU kg−1 in the brining group. Therefore, moderate Flavourzyme addition was excellent in improving sensory attributes and storage characteristics, whereas injection represented a novel method to obtain a similar fish meat quality in a shorter time and with less added Flavourzyme. © 2021 Society of Chemical Industry.

The aim of this study was to evaluate the characteristics and eating quality of salted noodles that are incorporated with different formulations of flour. Up to 20% of wheat flour was substituted by composite flours of highly resistant starches, including heat moisture treatment corn starch (HMT-CS), high-amylose corn starch (Hylon VII), and green banana flour (GBF). The physical properties of dough, in conjunction with the eating quality and estimated glycemic index (EGI) of cooked salted noodles, were investigated in this study. The results concluded that the incorporation of GBF, HMT, and Hylon VII not only affected the water absorption and mixing tolerance of the dough, but also the maximum resistance to extension and extensibility in terms of the extensographic properties. Meanwhile, GBF, HMT, and Hylon VII incorporation significantly increased the resistant starch content and decreased the fat content of the noodle samples. The textural profile analyses of cooked salted noodles indicated that hardness, gumminess, chewiness, and shearing force increased; nevertheless, springiness declined with the increase in the proportion of flours from 10 to 20%. The sensory evaluation detected that wheat flour composited with 10% GBF and HMT flours could produce acceptable quality noodles as compared with normal typical control noodles. In the meantime, salted noodles incorporated with GBF, HMT-CS, and Hylon VII flour decreased the estimated glycemic index (EGI) dramatically. The result of this study concluded that incorporation of various sources of resistant starch flour could develop a low-GI noodle with good acceptability that may contribute to gastrointestinal health.

Sodium nitrite (NaNO2) is a multifunctional meat-curing ingredient responsible for the unique reddish-pink color and flavor, microbiological safety, and shelf life extension of products. However, its use in the meat industry is controversial since NaNO2 is an exogenous source of nitric oxide, a nitrosating (nitrosamine-forming agent) and nitrosative stress agent (peroxinitrite precursor). Therefore, there is a great consumer demand for low-nitrite or nitrite-free meat products. Although it is difficult to remove the conventional NaNO2 owing to its beneficial properties, a partial or total substitute, without compromising the sensory attributes, may be effective. This review article presents and discusses the plant powders/extracts, atmospheric plasma, and pulsed electric field as new potential strategies for the total/partial substitution of conventional NaNO2 in meat products. The functionality of NaNO2 in meat products and the costs of its substitution are also provided. The information in this paper will open new vistas for scientists exploring the replacement of NaNO2, a hot topic for the meat industry. [ABSTRACT FROM AUTHOR]

To improve the water quality of micro-polluted lake water, an integrated process of dissolved air flotation (DAF)/modified attapulgite (M-ATP)/membrane filtration was applied to treat micro-polluted lake water with poor sensory attributes. The results showed that the average removal rate for water turbidity, color and odor using this process system were 95.8%, 83.1%, and 90.0% in order. Moreover, the M-ATP unit had the best treatment effect in turbidity and odor removal, with removal rates of 48.7% and 49.8%, respectively. While the DAF unit could remove 46.6% of the color at the same time. Based on the analysis of different processing units, the correlation between the removal rates of different processing units was explored using SPSS software. The results indicated that correlation between the three processing units is negative. In addition, in the three-month operation period, the initial transmembrane pressure (TMP) of the membrane device was about 2.3 kPa, and the final TMP was only about 4.5 kPa. This research provided technical reference for the treatment of micro-polluted lake water. [ABSTRACT FROM AUTHOR]

Today, the demand for functional products has increased. Apricot kernel is an important source of protein, oil, and fiber and has high antioxidant and antimicrobial properties. In this study, the effect of adding different levels (15% and 30%) of apricot kernel flour (AKF) to the cupcake formulation on the physicochemical, textural, and sensory attributes of the produced cupcake during 14 days of storage was investigated and optimized by the response surface methodology (RSM) to find the optimum cupcake production with respect to maintaining the quality attributes of produced cake during storage period compared with control sample. The results showed that increasing AKF significantly increased the consistency and apparent viscosity of the dough, as well as the volume, height, and percentage of cake baking loss, but the moisture content and hardness of the cake did not show a significant difference compared with the control sample. Also, the crust and crumb color of the samples containing AKF were significantly lighter than the control sample. The results of optimization process showed that addition up to 30% AKF improved the sensory properties such as the crust and crumb color, texture, porosity, aroma, taste, and overall acceptance compared with the control sample. Samples containing 30% AKF were selected as the best formulation by panelists. [ABSTRACT FROM AUTHOR]

The goal of this study was to assess the qualitative and sensorial characteristics of beef and pork sundried meat (SDM) with different salt (NaCl) levels (6%, 8% and 10%) and curing times (30 and 40 h). Samples from the beef strip loin (Gluteus medius) and pork loin (Longissimus thoracic) were cut to a thickness of 5 cm. Three levels of salt were applied, and the meat was allowed to cure for either 30 or 40 hours with three replications per treatment. The pH, shear force (SF), luminosity (L*), tonality (TON), saturation, loss of water by cooking (LWC), moisture, crude protein (CP), sensory attributes, and consumers' intention to buy were analysed. Beef and pork produced differences in L*, saturation, TON, and CP, appearance, and colour of the sun-dried product. The SDM cured for 30 hours was higher in moisture, LWC and L* (P =0.023), and had greater CP content than that cured for 40 hours. The appearance and salinity of the product were affected by the level of salt that was used in making it. In conclusion, various NaCl levels did not influence the physical-chemical and qualitative characteristics of the SDM, but these characteristics were influenced by the curing and meat type. In addition, the meat type and the salt level affected some aspects of the sensory evaluation. [ABSTRACT FROM AUTHOR]

Consumers increasingly address their attention to healthy fruits produced under organic agricultural managements. However, such produce may be less appealing in appearance influencing the purchase decisions of consumers. This research had the purpose to determine on three Italian local apple cultivars (Casciana, Rosa, Ruggine) the sensory appreciation of fruit through experiments conducted with blind (BC) and sighted (SC) consumers. The appreciation of apples differed between consumers with different visual ability. This aspect mainly concerned cvs Casciana and Rosa with contrasting fruit appearance traits. The BCs were inclined to better evaluate Casciana apples characterised by less attractive fruits. Conversely, the visual factor could have influenced the SCs' judgment, as they appreciated Rosa more by the best outer traits of fruits. Intriguing responses were obtained when SCs were blindfolded.

Objective: This study was conducted to investigate the effects of adding oregano (Origanum syriacum L.) and germander (Teucrium polium L.) to poultry diets individually and/or in combination: i) on cooked chicken meat quality and storage stability, ii) to compare this effect with those of the synthetic antioxidant butylated hydroxyanisole (BHA) and with the normal basic diet (Control: without supplements). Methods: Broilers (140 birds) were raised for 21 days and then equally divided into five different treatment groups of 28 birds each. The dietary treatments were as follows: i) control; ii) germander (GER, 1.5%); iii) oregano (ORE, 2.5%); iv) combination of GER and ORE (CM, 1.5%, and 2.5%); v) BHA (0.02%). Meat patties from the five treatments were prepared, cooked, and stored at 4°C prior to analysis. During storage, samples were measured for thiobarbituric acid-reactive substances (TBARS) and total carbonyl levels at 0, 4, and 7 days. In addition, cooked thigh meat was prepared separately to evaluate cooking loss and sensory attributes. Results: The CM dietary treatment showed the highest antioxidant effect, with decreasing TBARS values (breast and thigh meat) throughout the storage time (4 to 7 days). Furthermore, ORE showed a higher antioxidant effect, decreasing the rancidity development (TBARS values), compared to the GER during the storage period (days 0 to 7). The anticarbonyl effect of the CM supplement was the highest among all treatments from day 0 to 7. Generally, the antioxidant effect of GER was lower compared to that of ORE and BHA alone. The CM treatment most significantly decreased off-odor and rancidity development, with the lowest oxidation odor scores. Conclusion: The results indicate that the combination of oregano and germander in the diet of boilers improves meat quality and prolongs shelf life. [ABSTRACT FROM AUTHOR]

Context: Crude glycerin (CG) is an energetic byproduct that generates glycerol, an energy product that is absorbed by the ruminal wall and conducted to the liver, where it is metabolised and it is converted to glucose, by the action of the enzyme glycerol kinase, in a gluconeogenesis process. Aims: The study objective was to determine the effect of CG inclusion, replacing corn bran, in a total mixed ration to lambs, on carcass traits, physicochemical properties and the fatty acid (FA) profile of lamb meat. Methods: Forty-four uncastrated crossbred Santa Ines × indigenous lambs were distributed in a completely randomised study, with four CG inclusion levels (0, 70, 140 and 210 g/kg in the lamb diet). Key results: The addition of CG up to a level of 70 g/kg to the lamb diets promoted greater slaughter bodyweight, hot and cold carcass weight, carcass traits, and meat lipid content, and improved Warner–Bratzler shear force in meat. Inclusion of CG in the diet did not affect (P > 0.05) the pH and colour parameters (lightness, redness, yellowness and chroma) of meat. The FA composition of the longissimus lumborum of lambs C14:0, C15:1, C16:0, C18:1 cis and ΣFA medium-chain were greater, and FA meat concentration of C14:1, C15:0, C17:1, C18:0, C18:2 n −3, C18:2 n −6, ΣPUFA, ΣFA-old-chain and elongase enzymatic activity were lower in lambs fed without CG and with 70 g/kg CG, compared with lambs mainly fed 140 and 210 g/kg CG. The heath indexes, atherogenicity index and desirable FAs improved by dietary CG inclusion of 210 g/kg to the diet of lambs. Conclusions: CG obtained from biodiesel production can be incorporated in lamb diets up to 70 g/kg total mixed ration, replacing corn bran to improve the weight gain, meat lipid content, Warner–Bratzler shear force and FA profile of lamb meat. Meat fat-related consumers health indices improved from the biggest inclusions of CG to the diet of lambs However, the use of CG at levels 140 and 210 g/kg total mixed ration reduces the performance, carcass weight and morphometric measurements. Implications: It is recommended the inclusion at a maximum level of 70 g of CG/kg DM as total mixed ration replacing corn bran improves the weight gain, cooking weight loss, Warner–Bratzler shear force, meat lipid content and consequently FA meat composition. Crude glycerin is a byproduct of biodiesel production that can be used in the diets of ruminants to replace corn bran, because it has the potential to be a gluconeogenic and, therefore, energetic substrate. Enhancing the diet's energy density may improve the performance of animals, increasing the carcass fat content and thereby improving the physicochemical composition. Meat parameters, such as colour and shear force, generally represent the appearance, sensory traits and fatty acid profile of lamb meat. Other parameters can predict the meat acceptance by the consumer market. [ABSTRACT FROM AUTHOR]

Baltic sprats (Sprattus sprattus balticus) are a good source of protein, vitamins D3, B12, minerals, and unsaturated fats. In response to consumer demand, various types of fish products of stable quality are available all year round. Pre-treatment with brine containing acetic acid, salt (NaCl), and/or granulated CaCl2 in various concentrations and proportions can be used to stabilise quality. The aim of the study was to evaluate the effect of various pre-treatment methods on smoked Baltic sprat sensory and technological parameters. Prior to smoking, fish was treated in a solution of additives in various proportions for 30 min. Untreated sprats were used as a control sample. The use of pre-treatment allowed reduction of the smoking losses; the combination of NaCl and acetic acid resulted in about 26% smoking loss. If no pre-treatment was applied, the drying losses after 24-hour storage were 1.6%, while using the solution of NaCl and CaCl2 it decreased to 0.3%. Both the pre-treatment method and freezing affected fish pH. The pH of smoked fresh sprats was 6.73 and for smoked frozen sprats, it was 6.38. Sensory testing using the Just About Right (JAR) method demonstrated that the use of acetic acid made smoked fish texture firmer. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the effect of chitosan coating impregnated with Thymoquinone (TQ) and Eugenol (EUG) on the quality of rainbow trout fillets during cold storage (4ºC). In-vitro and In-vivo techniques were used to evaluate biopreservative effects of chitosan coating containing TQ, EUG and their combination. In-vitro evaluation of chitosan (2%) solution containing TQ, EUG demonstrated antibacterial and antioxidant effects. In-vivo assays on coated rainbow trout fillet as a food model demonstrated that the growth of spoilage bacteria, lipid oxidation and formation of volatile nitrogen bases reduced significantly in treated samples during 12 days cold storage in comparison with control samples and the treated samples were consumable until the 12th day without adverse sensory changes (P <0.05). Chitosan coating containing TQ and EUG can be used as a high quality packaging material to increase the shelf life of various foods, including fish, seafood, meat and meat products.

In this study, the effect of cinnamon essential oil (CEO) at 0.3 and 0.6 mg/mL concentrations loaded in the nanostructured lipid carriers (NLC) against Penicillium citrinum and Penicillium expansum involved in tangerine decay was investigated. The minimum inhibitory concentrations (MIC) of the CEO and CEO-loaded NLC against both P. citrinum and P. expansum were about 0.425 and 1 mg/mL, respectively. Moreover, the minimum fungicidal concentrations (MFC) of the CEO and CEO-loaded NLC were 0.675 and 1.5 mg/mL, respectively, and the values were approximately the same for P. citrinum and P. expansum. According to the chemical and sensory analysis during 25 days of storage at 25 °C, the CEO-loaded NLC reduced the weight loss (from 30.7 to 26.3% and 27.1% at 0.3 and 0.6 mg/mL CEO, respectively) and there was no detrimental effect on the organoleptic and chemical properties such as titratable acidity, pH, TSS, and ascorbic acid content due to the treatment with CEO-loaded NLC. The tangerines were inoculated with P. citrinum and P. expansum spores and the percentage of the infected wounds were evaluated during 25 days of storage at 25 °C. The fungal spoilage of tangerine fruits reduced during storage, significantly (from 100% on the 10th day to 31% and 33% on day 25 for P. citrinum and P. expansum, respectively). Therefore, CEO-loaded NLC has the potential to be introduced as a new treatment for increasing tangerine shelf life. [ABSTRACT FROM AUTHOR]

Neo-formed contaminants (NFCs) occurrence in coffee, a highly consumed beverage worldwide, has raised concern among different food safety agencies because a high intake of these toxic compounds may represent a long-term risk for the consumer health. The mechanisms responsible of NFCs formation in roasted coffee also trigger the generation of its desirable aroma and flavor characteristics. Hence their mitigation in coffee beverage while preserving these organoleptic properties represent a food safety challenge. This article performs a systematic review of the different strategies proposed for the NFCs mitigation in roasted coffee considering their effect on the bioactive compounds content and the sensory characteristics of the final product. The mechanisms of NFCs formation are addressed as the main axis for the rational design of technologies for their mitigation. Available technologies for decreasing the NFCs (acrylamide, furfuryl alcohol, furan and 5-hydroxymethylfulfural) levels in roasted coffee were grouped in two main categories: (i) mitigation (before or during roasting) and (ii) reduction (after roasting). The understanding of the mechanisms responsible of NFCs formation allowed to establish different alternatives for their mitigation in roasted coffee. However, the greatest challenge still lies in guaranteeing a final product low in NFCs with desirable sensory and bioactive characteristics. The rational design of strategies that decrease the occurrence NFCs in roasted coffee without affecting its nutritional and sensory quality must consider the inclusion of pre-roasting stages such as fermentation and drying into the mitigation technology. • NFCs control technologies in coffee can be grouped into mitigation and reduction. • The NFCs mitigation in coffee needs a global approach, not in a particular way. • Pre-roasting stages such as fermentation can be key to mitigate NFCs in coffee. • Some technologies mitigate NFCs of coffee affecting their sensory properties.

This study aimed to evaluate the intake, digestibility, feeding behavior, performance, carcass traits, and meat quality of feedlot Santa Inês (locally adapted breed) and Dorper (transboundary breed) lambs. Twenty non-castrated lambs were used (10 from the Santa Inês genetic group and 10 Dorper), with approximately 3 months of age and an initial body weight of 22.95 ± 2.1 kg (mean ± standard deviation), distributed in a completely randomized design. Nutrient intake and digestibility, feeding behavior, and liver metabolism enzymes were similar (P > 0.05) between genetic groups. Dry matter (DM) feeding and ruminating efficiency were higher (P < 0.05) in the Santa Inês genetic group. There was also no difference (P > 0.05) in the subjective evaluation and morphometric measurements. Genetic groups showed differences and trend to differences (P < 0.05) in performance and commercial cuts. The physicochemical characteristics, centesimal composition, and sensory attributes of the Longissimus lumborum muscle did not differ between the genetic groups (P > 0.05). The Santa Inês genetic group showed higher feeding efficiency and productive parameters when compared to Dorper lambs. Therefore, Santa Inês lambs have greater potential for meat production than Dorper lambs, when kept in the same breeding system as the feedlot. [ABSTRACT FROM AUTHOR]

The present study was undertaken to see the impact of incorporation of aloe vera juice on the sensory and physico - chemical characteristics of juice blends. Aloe vera juice was incorporated into the best combination out of six different combinations of carrot - orange juice (CO) blends. Addition of aloe vera juice brought significant decrease in total solids, TSS, titrable acidity, reducing sugar and total sugar content of carrot orange - aloe vera juice (COA) blends. Ascorbic acid and beta carotene content of carrot - orange juice (CO) was found to be significantly higher than carrot orange - aloe vera juice (COA) blends. No significant difference was observed in the sensory attributes of CO and COA juice blends. [ABSTRACT FROM AUTHOR]

Background: Intranasal steroid (INS) is the most effective medication class for controlling allergic rhinitis (AR) symptoms; however, its effectiveness is limited by patient compliance. Previous studies have explored INS use, compliance, satisfaction, and experience. There is, however, no Asian study on these factors in entirety. Objective: We aimed to investigate the rate of compliance to usage of INS and explore the reasons for noncompliance in our local population. Methods: We conducted a prospective cross-sectional study on 65 AR patients in a tertiary hospital. Recruited patients were administered a questionnaire to collect data about symptoms, INS use, and concerns they may have. Statistical analysis was performed using SPSS. Results: The overall compliance rate to INS was 63.1%. Noncompliance was associated with increased frequency of dosing (p = 0.050), presence of sensory attributes (p = 0.041), and forgetfulness (p = 0.049). The top 3 most frequent sensory attributes experienced by patients include throat rundown (29.2%), aftertaste (21.5%), and immediate taste (20.0%). There was a significant difference between brands of INS with regard to sensory attributes experienced (p = 0.003) but no side effects (p = 0.070). Conclusions: Identifying risk factors for noncompliance to INS can help health-care providers address difficulties faced by patients and hence increase compliance, allowing better control of AR symptoms.

This study investigates the impact of two extraction processes (squeezing the whole fruit and centrifuging the seeds) of pomegranate juice and storage on sweet and sour pomegranate quality attributes. The pH, acidity, and levels of organic acids, sugars and anthocyanin differed in both varieties and changed during the storage period. Fructose and glucose were the primary sugars, and citric acid was the dominant organic acid in the juice of both cultivars. A high level of established anthocyanin content was 15.40, 18.53, 18.03, 16.92, 16,68 and 15.47 mg/L when the storage period was 0, 5, 15, 32, 48 and 72 h, respectively, in the juice of sweet fruits obtained by squeezing the whole fruit. The juice prepared from the sweet fruits by squeezing method outscored, in all sensory quality attributes, the juice prepared by centrifuging process. [ABSTRACT FROM AUTHOR]

This study was aimed at evaluating the effect of freeze-drying and lacto-fermentation on the texture parameters of images and sensory attributes of beetroots. The samples were imaged using a flatbed scanner, and textures from images converted to color channels L, a, b, R, G, B, X, Y, Z were computed. The discrimination of raw and processed beetroots was performed using models based on textures selected for each color channel. The sensory quality of processed samples was determined using the attributes related to smell, color, texture and taste. The highest discrimination accuracy of 97.25% was obtained for the model built for color channel b. The accuracies for other channels were equal to 96.25% for channel a, 95.25% for channel R, 95% for channel Y, 94.75% for channel B, 94.5% for channel X, 94% for channel L, 92.5% for channel G, 88.25% for channel Z. In the case of some models, the raw and lacto-fermented beetroots were discriminated with 100% correctness. The freeze-dried and freeze-dried lacto-fermented samples were also the most similar in terms of sensory attributes, such as off-odor, attractiveness color, beetroot color, crunchiness, hardness, bitter taste, overall quality. The results indicated that the image parameters and sensory attributes may be related. [ABSTRACT FROM AUTHOR]

Background. Herbs and spices are natural ingredients that have been widely used not just as food flavouring but also for their health attributes. The antioxidant, antimicrobial and anticancer components present in them enhance the health and medical status of human beings. The present study aims to produce Labneh fortified with cardamom and bay leaf powder to enhance the quality and shelf life. Materials and methods. Cardamom or bay leaf powder were added separately at the ratios of 0.25, 0.50, 0.75 and 1% (w/w) to Labneh and the treatments were compared with a control without cardamom or bay leaf powder during storage (at 5 ±1°C for 40 days). Results. The total solids, fat, ash, carbohydrate and fiber contents were insignificantly higher in Labneh containing cardamom or bay leaf powder than control. The titratable acidity of Labneh gradually increased, whereas the pH values decreased by increasing the concentration of cardamom or bay leaf powder during the storage period. No significant differences were found in any textural parameters between Labneh containing condiments and control, except for that containing 1% cardamom or bay leaf powder, which exhibited higher hardness during the storage period. Minerals, antioxidants activity (RSA%), total phenolic (TPC) and total flavonoids content (TFC) increased with the increase of the added percentage of cardamom or bay leaf powder compared to control. Due to the stimulatory effect of cardamom and bay leaves on Lactic acid bacteria (LAB), the viability of the total bacterial count (TBC) gradually increased as the level of those condiments increased. The control became moldy after 10 days of cold storage while Labneh containing condiments remained unspoiled with yeasts and moulds for up to 30 days of cold storage. Sensory evaluation indicated that 1% addition of cardamom and 0.75% of bay leaf powder to Labneh improved quality and extends the shelf life of Labneh up to 30 days at 5 ±1°C. Conclusion. Labneh supplemented with cardamom or bay leaf powder can be considered as a novel product with acceptable quality and extended shelf life. [ABSTRACT FROM AUTHOR]

Protein and vitamin A deficiencies are two public health concerns in Nigeria. This study investigated the quality attributes of biscuits prepared from yellow fleshed cassava flour (YFCF) and quality protein maize flour (QPMF). The proximate, mineral and antinutrient composition, β-carotene content and color attributes of the composite flour and biscuits were determined. Data were subjected to analysis of variance and the means separated by Duncan’s Multiple Range Test. The protein and β-carotene contents of the flour blends ranged from 5.69 to 8.54% and 1.45 to 2.76 µg/g, respectively. On the other hand, the biscuits contained 11.38 to 14.6% protein and 1.35 to 1.82 µg/g β-carotene. The protein, ash, crude fiber, spread ratio and mineral composition of biscuits increased as QPMF increased. The hardness of the biscuits decreased with increase in QPMF. Furthermore, the mean sensory scores of the biscuits revealed that they were liked moderately. However, the most acceptable biscuit was the one prepared from 20% YFCF and 80% QPMF.This study has demonstrated the possibility of producing acceptable biscuit from quality protein maize, which could be used in school feeding programmes in Nigeria.

Flavoured honey is an increasingly popular product among consumers. Enriching honey with other healthy ingredients such as spices, herbs, dried fruits, pollen and propolis is a way to create new innovative products, with benefits for both, beekeepers and consumers. The purpose of the study was to test four types of flavoured honey among young consumers segment in Slovakia: honey with cacao, honey with cinnamon, honey with turmeric and honey with pollen, by using an interdisciplinary approach. The research combined sensory analysis, consumer research and laboratory tests methods aiming to find the consumer interest and acceptability of these products. Based on overall sensory analysis, honey with cacao and cinnamon obtained the best evaluations in terms of aroma, taste and colour, while honey with turmeric obtained the worst. Laboratory tests showed that all four types of flavoured honey have higher antioxidant activity than normal pure honey. Communicating these results to consumers partially influenced their preferences. The results of consumer research indicate that flavoured honey was perceived as innovative and natural product and the majority of respondents would buy it.

Craft beer is an authentic product characterised by unique sensory features that distinguish it from industrially produced beers. The typical consumer also closely associates craft beers with the concept of traditional products, also in terms of consumption habits and the manner in which they are packaged. In this research, 482 beer consumers were interviewed face-to-face using a paper questionnaire during the Oktoberfest (Piedmont-Northwest Italy), a traditional beer festival that draws thousands of craft beer fans. Two consumer samples were defined on the basis of individual statements regarding their preferred method of beer packaging: The “traditional” consumer, loyal to the conventional beer packaging material (glass bottle) and the “innovative” consumer more inclined to packaging innovation (the use of aluminium cans). The preference scores towards beer attributes of the two identified samples were assessed using a 5-points Likert scale. In addition, the individual socio-demographic characteristics, together with craft beer consumption habits were recorded during the data collection phase. Significant differences between the two consumer samples were found using a non-parametric test; the Mann-Whitney Wilcoxon. In particular, traditional and innovative consumer groups expressed different preference levels towards beer clarity, colour, bitterness and body. For both samples, taste intensity resulted as the top attribute for beer evaluation, highlighting that, even when canned, the consumer is able to evaluate and appreciate the aromatic and quality characteristics of the product. Therefore, although glass remains the preferred packaging material for craft beer consumers, given the increasing acceptance of canned packaging by the traditional consumer, brewers could conceivably focus on canned product lines in order to exploit the inherent logistical and marketing advantages (i.e. graphical communications).

Ethiopia is known for its specialty Arabica coffees affected by mix-up. Physical and sensory properties of dry processed green coffee beans have been reported for the influence on the sensorial quality and coffee process optimization. The aim of this study was to investigate physical and sensory properties of sixteen varieties and to determine relationship of attributes. Physical properties of coffee beans were taken by measuring linear dimensions, densities and weight. Moreover, professional cuppers were analyzed sensory properties by using standard procedures. In this study, the longest (10.40 mm), the widest (6.82 mm) and the thickest (4.48 mm) varieties were Odicha, Feyate and Challa, respectively whereas the shortest (8.28 mm), narrowest (5.59 mm) and thinnest (3.52 mm) were 74110, Mocha and Bultum, respectively. The shape & make value of variety Bultum was “fair good” whereas variety Feyate was “very good”. Furthermore, the results of “shape & make” were significantly correlated with measured physical properties. The results indicate that most physical and sensory properties of coffee varieties have significant (P ≤ 0.05 differences. These properties were influenced by growing regions and variety difference. The outcome of this study can be used for coffee bean characterization and process optimization to improve beverage quality.

The data on 837 birds representing five crosses (Aseel x PD-1, Aseel x PD-2, Aseel x PD-6, Aseel x PB-1 and Aseel x PB-2) survived up to 12 weeks of age were evaluated for various growth, meat quality, meat composition, sensory attributes and carcass traits as an alternative to native chicken farming. Body weights and shank lengths significantly (P≤0.05) differed at all ages. Aseel crosses with coloured broiler lines (PB-1 and PB-2) had significantly (P≤0.05) higher body weights while Aseel x PD-1 cross recorded higher shank length at all ages. The fat and ash proportion varied significantly (P≤0.05) among the crosses. The pH values of the breast meat ranged 5.89 to 6.29. The Shear force values (SFV) and Hydroxyproline (HP) concentration differed significantly (P≤0.05) among the crosses. Meat colour differed significantly (P≤0.05) with respect to yellowness (b*) and red (a*) colouration. The proportion of legs, wings, back, neck, meat and bone significantly (P≤0.05) differed among the crosses. The cluster analysis of means of all traits revealed that least distance exists between Aseel x PD-1 and Aseel x PD-6. The study concludes that, Aseel x PD-1 and Aseel x PD-6 crosses may be a viable and suitable alternative for native chicken farming.

Defatted dabai (Canarium odontophyllum Miq.) parts are considered good sources of antioxidants. This study aimed to determine the nutritional values and antioxidant properties of dabai cocoa bars and the sensory profile scores of different parts of dabai fruits (oil, oleoresin, and kernel). The second part of this study included the formulation of dark dabai cocoa bars using different percentages (5%, 10%, 15%, 20%, 25%, and 35%) of dabai kernel. The antioxidant activities of the dark dabai and dabai cocoa bars were determined on the basis of DPPH free radical scavenging and thiobarbituric acid reactive species assays. The panelists of the sensory study were asked to score specific sensory attributes using a hedonic scale. Results of the triangle test indicated that the flavor score of the dabai cocoa bar with 40% dabai oleoresin was low and its other sensory scores (aroma and overall acceptability) were also lower than those of the other types of dabai and dark dabai cocoa bars. Furthermore, the dark dabai cocoa bars with 5–35% dabai kernel exhibited an improved formulation, and the cocoa bar containing 20% dabai kernel presented the lowest lipid peroxidation value and higher overall acceptability score than the cocoa bar with 5% dabai kernel. However, the cocoa bar with 5% dabai kernel achieved the highest estimated total phenolic content and DPPH radical scavenging capacity. The β-carotene bleaching inhibition of the dark cocoa (DC) bar was not significantly higher than the cocoa bar with 40% dabai oleoresin. Lastly, the sensory acceptance score of dabai cocoa bars was lower than that of the DC bar due to the crispiness of dabai kernel and the astringent taste of dabai parts. Thus, dabai kernel preparation should be optimized further.

Aroma is one of the most important sensory properties of tea. Floral-fungal aroma type, ripe-fungal aroma type and fresh-fungal aroma type were the main aroma types of Fu brick tea by QDA. A total of 112 volatile compounds were identified and quantified in tea samples by HS-SPME/GC–MS analysis. Ten voaltiles in floral-fungal aroma type, eleven voaltiles in ripe-fungal aroma type, and eighteen voaltiles in fresh-fungal aroma type were identified as key aroma compounds for the aroma characteristics formation in three aroma types of Fu brick tea. In addition, PLS analysis revealed that 3,4-dehydro-β-ionone, dihydro-β-ionone, (+)-carotol and linalool oxide Ⅱ were the key contributors to the ‘floral and fruity’ attribute, α-terpineol contributed to ‘woody’ and ‘stale’ attributes, and thirteen aroma compounds related to ‘green’ attribute. Taken together, these findings will provide new insights into the formation mechanism of different aroma characteristics in Fu brick tea.
