Gluten-free and vegan bakery items have been gaining popularity. Their demand has increased over the past few years, with India being one of the largest gluten-free food consumers. The gluten-free pieces of bread available in the market are crumbly in nature and have a dry mouthfeel, reducing its overall acceptability among consumers. Therefore, the present study was undertaken to develop gluten-free and vegan bread and enrich it with a functional component such as flaxseeds and assess its overall acceptability and nutritional value compared to gluten-free bread available in the market. Once the product was standardized for its serving size and yield, various sensory evaluation trials were conducted using 9 points hedonic scale on bread attributes with the help of semi-trained(n=30)and trained panellists(n=3). Proximate analysis of macronutrients was conducted along with the microbial analysis. The proximate analysis showed that the experimental product had a higher protein content(18.26g)and a lower fat content (5.58g) as compared to the market-bought control sample of gluten-free bread (Total protein content was 3.44g and total fat content was 9.20g). The experimental bread microbial analysis indicated that the total plate count, yeast and mold count, and coli form count were in the acceptable range. Salmonella and E.coli were absent in the sample Statistical analysis using paired t-test was performed found a significant difference between the experimental and control group among the following characteristics: taste/flavour, texture/mouth feel, and overall acceptability (p≤0.05). A shelf-life study of the bread was conducted, and it was seen that the bread remained sensorial acceptable for three days at a refrigerated temperature and four days at room temperature. The bread had a higher nutritional profile than the control sample and received higher overall acceptability.

The production and determination of the nutritional properties of cookies produced by partial substitution of margarine with avocado pear pulp was studied. Well cleaned avocado pear was blended into paste and used to substitute margarine in the prepared cookies. The ratio of avocado pear pulp substituted was 20%, 30%, 40% and 50%. The substituted products and the control (100% margarine) were subjected to physicochemical and sensory evaluation. The results of the proximate analysis showed that the protein content ranged from 6.93% -7.83% with sample A having the highest protein content and fat content. Moisture content and ash content of samples were seen to be higher in sample E (50:50 ratio). Sample A had the least value of moisture, ash and crude fibre with moisture content of 11.13%, ash content of 1.40% and crude fibre value of 0.29%, while sample E  recorded the least value of crude fat  (16.00%). The carbohydrate content was recorded to be higher in sample C. The physical properties showed that cookies made with higher avocado pear pulp had less thickness compared to the control cookies. The sensory evaluation results showed that sample A had the highest values of 8.05%, 7.85% and 7.95% for appearance, taste and aroma respectively while sample E (50:50 ratio) had the least values in crunchiness, taste and aroma. The overall acceptability of the results showed that sample A recorded the highest value but not significantly different (p<0.05) from sample B (80:20 margarine avocado). The research concluded that the partial substitution of avocado improved the nutritional value of the cookies by lowering the saturated fat content.

Ogi was produced from composite flour of fermented Acha, roasted Soybean and Carrot.  The raw materials were blended in varying proportions. Proximate composition, functional properties and sensory characteristics of the formulated Ogi samples were evaluated. The results of the proximate composition showed a significant increase in moisture (5.36% to 9.94%), protein (3.94% to 16.98%), fat (1.89% to 10.23%), crude fiber (1.80% to 3.12%) and ash (0.35% to 0.99%); while a decrease was observed in carbohydrate (86.66% to 58.74%) with increase in supplementation with roasted Soybean flour and constant addition of carrot flour along with the milk flavor. The functional properties showed significant increase in foam capacity (5.99% to 7.97%), Swelling index (2.46 v/v to 3.08 v/v) and Least gelation capacity (8.10% to 14.0%); while a decrease was observed in bulk density (0.84 g/mL to 0.72 g/mL), water absorption capacity (1.40% to 1.10%) and foaming stability (3.39% to 2.79%). Sensory characteristics result revealed that there was no significant difference (p<0.05) in aroma and overall acceptability with increasing incorporation of roasted Soybean flour and constant addition of Carrot flour with milk flavor. Aside the control sample (containing 100% fermented Acha flour) there was preference for Sample C (70% fermented Acha flour: 15% roasted Soybean flour: 10% Carrot flour: 5% Milk flavor) and Sample D (60% fermented Acha flour: 25% roasted Soybean flour: 10% `Carrot flour: 5% Milk flavor) in terms of color (6.65 and 6.25), taste (6.95 and 6.35), aroma (6.45 and 6.30), mouth feel (6.10 and 6.35) and overall acceptability (6.50 and 6.50) respectively, among the blend formulations. Supplementation of fermented Acha with roasted Soybean and Carrot flour considerably increased the protein and fat contents of the blend; hence Soybean should be used for supplementation of cereal based product in order to improve their nutritional composition.

В России наблюдается повышенный интерес к продуктам питания, включающим нетрадиционное сырье. Спрос на продукты с добавкой семян конопли (Cannabis sativa L.) обусловлен их питательной ценностью и низкой аллергенностью. Исследованы химические и физико-химические показатели пшенично-конопляной муки, полученной из помольной смеси зерна яровой пшеницы сорта Радмира и семян конопли сорта Сурская в соотношении соответственно 95 : 5, 92,5 : 7,5 и 90 : 10%. В качестве контрольного образца была пшеничная мука без добавок. Размол помольных пшенично-конопляных смесей различного соотношения и зерна пшеницы проводили на мельницах лабораторного помола (МЛП-4) с нарезными (драные системы) и микрошероховатыми вальцами (размольные системы). Исследование химических и физико-химических свойств образцов пшенично-конопляной и пшеничной муки проводили на инфракрасном анализаторе SpectraStar 2500 XL. Установлено, что добавление семян конопли в помольную смесь существенно снижает выход пшенично-конопляной муки по сравнению с выходом пшеничной муки (при добавке 5–7,5% семян конопли выход снижается на 4,3–4,4%, а при добавке 10% семян конопли – на 10,6%), однако повышается содержание жира и белка во всех потоках пшенично-конопляной муки, полученной как с драных, так и с размольных систем. По сравнению с содержанием жира и белка в муке из зерна пшеницы, составившим 1,12 и 11,57% соответственно, при добавлении 5% семян конопли в помольную пшенично-конопляную зерновую смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 3,76%, а содержание белка – 12,74%, при добавлении 7,5% конопли в помольную смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 4,35%, а белка – 12,7%, при добавлении 10% конопли в помольную смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 4,97%, а содержание белка – 12,4%. Повышение содержания жира и белка в пшенично-конопляной муке будет способствовать повышению пищевой ценности хлебобулочного изделия из нее. Increased interest in food products, including non-traditional raw materials, is observe among the population of Russia. The demand for products with the addition of hemp seeds (Cannabis sativa L.) is due to their nutritional value and low allergenicity. Chemical and physico-chemical parameters of wheat-hemp flour obtained from a grind mixture of Radmira spring wheat grain and Surskaya hemp seeds in the ratio: 95 : 5, 92,5 : 7,5 and 90 : 10%, respectively, were investigated. Wheat flour without additives was use as a control sample. Grinding of grind wheat-hemp mixtures of various ratios and wheat grains was carried out in laboratory grind mills with rifled (torn systems) and micro-roughened rollers (grinding systems). The study of chemical and physico-chemical properties of wheat-hemp and wheat flour samples was carried out on the SpectraStar 2500 XL infrared analyzer. It was found that the addition of hemp seeds to the grind mixture significantly reduces the yield of wheat-hemp flour compared with the yield of wheat flour (with the addition of 5–7,5% of hemp seeds, the yield decreases by 4,3–4.4%, and with the addition of 10% of hemp seeds – by 10,6%), however increases the fat and protein content in all streams of wheat-hemp flour obtained from both torn and grinding systems. Compared with the fat and protein content in wheat flour, which amounted to 1,12 and 11,57% respectively, when adding 5% hemp to the wheat-hemp grain mixture, the weighted average fat content in wheat-hemp flour was 3,76%, and the protein content was 12,74%, when adding 7,5% hemp to the grind mixture, the weighted average fat content in wheat-hemp flour was 4,35%, and protein – 12,7%, and when adding 10% the weighted average fat content in wheat-hemp flour in the grind mixture was 4,97%, and the protein content was 12,4%. An increase in the fat and protein content in wheat and hemp flour will contribute to an increase in the nutritional value of a bakery product made from it.

in recent years, great attention has been paid to the quality of eaten meat and its products. There have been launched a lot of promotional campaigns aimed at providing opportunities for the consumption of traditional products. Based on the experiment, a significantly higher protein content was found in sausages produced by large producers (24.73 &plusmn; 1.98%). The fat content was significantly higher in traditional ham (16.25 &plusmn; 14.47%), compared with local ham (4.38&nbsp;&plusmn; 2.26%) and the mass (9.29 &plusmn; 5.25%). The samples of traditional and local ham had a significantly higher salt content (3.31 &plusmn; 0.72 and 2.90 &plusmn; 0.54%, respectively). No dye compounds were detected in any of the tested samples. There were no statistically significant differences in hydroxyproline and l‑glutamic acid content between traditional and conventional samples of meat products. Analysis of nitrate (V and III) showed a statistically significant difference in the average contents of these compounds. Significantly higher levels of nitrates were revealed only in traditional ham samples (12.60 &plusmn; 8.08 mg NaNO(V)/kg and 17.53 &plusmn; 27.91 mg NaNO(III)/kg of the product, respectively), wherein there was a large variation in the content of these compounds in the samples.

This study compares the effects of different levels (0 to 50%) of Gliricidia sepiun leaves on the processing, proximate composition, and organoleptic characteristics of male and female rabbits using a 3 x 2 x2 factorial design. The effect of 8 weeks of cold storage at - 20+20 C on acceptability of the rabbit meat was also evaluated. The data obtained showed that the live-weight, dressing percentage, and fat content of the rabbits fed 25% Gliricidia sepium were higher than those from 0 % (control) or 50 % level at 10 weeks old. The total cooking losses were higher by 15 to 24% in the frozen roasts, due mainly to increased drip and evaporative losses which were also slightly higher in the female carcasses. The expressible moistrue index (EMI) increased in the frozen samples, and no significant difference (P>0.05) was found to be attributable to diet. The final moisture content and cook yield of the frozen samples decreased, whereas the ash content was not significantly affected by sex or diet. However, the protein and fat contents, and pH increased regardless of sex in all the cooked samples. The sensory evaluation results are suminarized as follows: (1) fresh roasts from rabbits fed 25% Gliricidia sepiun were preferred, possibly, influenced by tenderness scores and slightly higher fat content; and (2) meat roasts from the frozen samples did not differ on overall acceptability, although the palatability scores diminished at the end of 8 weeks of frozen storage, and panelists did not detect any significant differences (P>0.05) attributable to diet or sex.

This study was aimed to investigate the functional properties of peanut seeds, and physicochemical, nutritional and sensory analysis of processed peanut milk. Standard methods were used in this research to determine the functional properties and proximate composition, while minerals were determined by a flame photometer and colorimeter. Firstly, the functional proprieties of the whole and defatted kernel of peanut seeds were studied, and the best results were found in the defatted sample. Peanut milk samples were divided into four samples depends on the percentage of powder milk addition (3, 6, 9 and 12%) as well as the control sample without addition. The pH, total soluble solids, viscosity, and density of samples were (6.2-6.5, 6-16%, 3-8 mPa/s, and 1.01-1.05 g/cm3, respectively), increased with the increasing of milk powder. About the proximate analysis, the highest values of ash, protein, fat, total carbohydrates (0.8, 6.3, 6.3, and 7.5%, respectively) were found in the sample of 12% powder milk. Sodium, potassium, and calcium in the samples (3, 6, 9 and 12%) were found in the range 38-58, 55-89, and 10-18 mg/100 g, respectively. Sensory evaluation results revealed great acceptance for peanut milk made with 3% powder milk addition, while we're not found a significant difference in the color and taste of all samples and control. This study proved the possibility of using Sudanese peanut as a milk substitute which was found to be a good source of nutrients. This study suggested using peanut milk as a milk substitute, and in yogurt manufacture, future work should aim at studying optimum storage conditions and stable packaging requirements.

In this study, a maize based local snack aadun was formulated from yellow maize flour and ripe plantain blends in a bid to improve its quality. The snacks were subjected to microbial analysis using pour plate method, proximate composition, mineral content and the sensory properties of the snacks were assessed. The results indicated bacterial count ranging from 1.20 to 2.80 x 102 cfu/g. Also, there were no coliforms and enteric bacteria on the aadun samples albeit, there were more bacteria on aadun supplemented with plantain. Two bacteria and three fungi were isolated from the aadun samples, they were Bacillus subtilis, Staphylococcus aureus, Saccharomyces cerevisiae, Aspergillus niger, and Rhizopus stolonifer. The protein and carbohydrate were comparable for the samples while the higher moisture, fiber, ash and carbohydrate were recorded in plantain supplemented aadun with significant increase at a higher content of plantain. Sample C had the highest moisture (6.72%), fiber (7.62%) and ash (2.39%) content in comparison with the other samples whereas, the plain aadun had higher crude fat (32.29%) compared with the aadun containing plantain. The level of calcium and magnesium in the plain and aadun containing plantain were similar without significant differences. However, the level of potassium and phosphorus were significantly higher in aadun supplemented with plantain than in the plain aadun whereas sodium was found to be higher in plain aadun (289.20 mg) than the supplemented samples. There was no significant difference in the appearance and aroma of the plain aadun and plantain supplemented aadun. However, aadun with 50% plantain was ranked as the most preferred samples in terms of taste, texture and overall acceptability with a score of 8.41, 6.31 and 8.33 while the plain aadun had 4.52, 4.22 and 5.79 respectively for these properties. These indicate that aadun may be improved with inclusion of plantainup to 50% proportion.
