Synthetic Evaluation

To improve the antioxidant activity (AA), digestibility, and quality of fiber-rich dumpling wrappers, potato, okara, and konjac flours were added to wheat flour. The contents of these additional ingredients in the dumpling wrapper were optimized using the response surface methodology and the synthetic evaluation method. The dietary fiber content (DFC) and AA of blend flours and the optimized cooking time (OCT), cooking loss (CL), hardness, chewiness, firmness, color, and sensory evaluation (SE) of dumpling wrappers were evaluated as response quality parameters. The optimized flour was identified containing 17.5 g of potato flour, 8.5 g of okara flour, and 1.2 g of konjac flour per 100 g of blend flour, which resulted in a higher synthetic evaluation index value (0.71 compared with 0.68 for wheat flour). The qualities of the optimized flour dumpling wrappers were compared with those of wheat flour dumpling wrappers to verify the practicality of the optimized flour. The results showed that the optimized flour showed better comprehensive qualities, especially regarding DFC (9.59%, fourfold higher than that of wheat flour) and AA. Furthermore, the predicted glycemic index (GI) of the optimized flour (74.93%) was lower than that of the wheat flour (81.47%). Overall, the addition of potato, okara, and konjac flours can significantly (P<0.05) improve DFC, AA, and digestibility of wheat flour. The optimized flour not only maintains excellent dumpling wrapper quality but also increases the utilization of potato and okara flours, which has great potential for industrial applications.

Гибриды сахарной и сверхсахарной кукурузы являются хорошим сырьем для производства функциональных пищевых продуктов, в том числе диетического и детского питания. Важными показателями высокого качества этих продуктов являются повышенное содержание белка и ценного масла, незначительное количество плохо усвояемого кукурузного крахмала и высокое содержание антиоксидантов, а также отменные вкусовые качества. В работе представлены данные по оценке антиоксидантной активности большой группы новых перспективных гибридов сверхсахарной кукурузы среднеспелой группы, созданных с целью получения ценных источников сырья для консервной промышленности. Значения показателя общей антиоксидантной активности варьировали в широком интервале значений (от 31,8 % до 60,4 %, 568,4–1008 мкг/г семян), что указывает на перспективность использования этого важного биохимического параметра в селекции сверхсахарной кукурузы на качество. Hybrids of excess sugar maize are good raw material for the production of functional food products, including baby food and diet. Important indicators of high quality of these products are high protein content and a valuable oil, a small amount of poorly digestible maize starch and a high content of antioxidants, and also excellent taste qualities. The paper presents data on the evaluation of the antioxidant activity of a large group of promising new hybrids of excess sugar maize of mid-group created in order to obtain valuable raw materials for the canning industry. Index value of total antioxidant activity varied over a wide range (from 31,8 % to 60,4 %, 568,4–1,008 mg/g of seed), which indicates on promising use of this important parameter in the breeding of biochemical excess sugar maize on quality.

This investigation was conducted to determine the effect of organic fertilizers on the content of chlorophyll a, chlorophyll b, antioxidant activity, crude fibre, and zinc in two onion cultivars, Stuttgarter Riesen and Rote Laaer, during 2016, 2017, and 2018. In this research, the following treatments were used: B-Stimul (contains Azospirillum Tarrand et al., Azotobacter Beij., Bacillus Cohn, Chlorella vulgaris Beij., and Herbaspirillum Baldani et al.), EkoBooster 2 (contains biostimulators and mineral salts of nitrogen, phosphorus, and potassium) and Vermifit A (extract of compost of Californian earthworm). The results showed that the application of biofertilizers to onion resulted in the highest chlorophyll b content in 2017 in Stuttgarter Riesen. EkoBooster 2 positively affected crude fibre content in both cultivars, but only in 2016. Antioxidant activity was not significantly affected by the interaction of experimental factors. The application of the biostimulating fertilizers can have a positive impact on the quality parameters of onion, but the kind of fertilizer must be suited to seasonal conditions and the cultivar.

The paper examines the effect of native and germinated pumpkin and watermelon seeds on the quality of semi-finished and finished bread products. Native and germinated seeds, pre-dried and ground into flour, were used as an additive to bread in the amount 5%, 10%, 15% by weight of the flour. Pumpkin and watermelon seeds were added in order to enrich the bread with micronutrients. The influence of these additives on the quantity and quality of gluten has been analysed. It has been found that the addition of pumpkin seed flour in quantities of 5%, 10% and 15% by weight of wheat flour leads to a decrease in the gluten content and an increase in its elasticity. The study has shown that adding native pumpkin seeds does not have a significant effect on the moisture and acidity of semi-finished and finished products, and adding germinated seeds leads to a slight increase in these parameters. Thus, the moisture content of the crumb with native pumpkin and watermelon seeds added increased by 0.2–1.3%, as compared with the reference sample, and with germinated seed flour added, it increased by 0.5–2.2%. The acidity of the crumb changes slightly, within experimental error. According to the physicochemical quality parameters, the most practical amount of the additives is 5% by weight of wheat flour. A comparative analysis has been carried out to establish how addition of 5% of native and germinated pumpkin and watermelon seeds changes the organoleptic properties of bread. The analysis has shown that ready-made bread products containing native pumpkin seeds taste better and have better olfactory properties than products with germinated seeds. The nutritional and calorific values of the reference sample and of bread with 5% of pumpkin and watermelon seed flour have been compared and characterised. It has been found that the addition of native pumpkin seeds will increase the content of minerals: of iron by 230%, of magnesium by 116%, and of potassium by 118%. The addition of native watermelon seeds will increase the phosphorus content by 13%. As a result of this research, the prospects of using flour of native pumpkin and watermelon seeds to fortify wheat bread have been shown

Solvent Retention Capacity

The physicochemical, microbial, and antioxidant properties of a Korean wheat variety (Jokyoung) were measured according to milling yield (60–90%) by adding fractions from millstreams. As the milling yield increased, the wheat flour showed low quality on physicochemical properties in general. Significant differences in proximate analysis, color, solvent retention capacity, pasting property, and antioxidant activity were observed as the yield increased to maximize the production of wheat flour from wheat kernels. Adding clear flour and shorts did not significantly affect the quality of the wheat flour in comparison with straight flour samples. However, as brans were added to the flour portion, the wheat flour quality parameters decreased significantly in color, solvent retention capacity, and pasting properties. On the other hand, antioxidant properties increased as brans were added. Maximizing wheat flour yield is a key to minimizing the production cost of Korean wheat flour, which is approximately three times more expensive than imported wheat flour. Adding clear flour and a certain portion of shorts did not seem to significantly influence the overall quality of wheat flour from Korean domestic wheat variety.

Quality of minimally processed jackfruit bulb was evaluated during storage at different storage times, temperatures, and types of packaging. The jackfruit pulps were first dried at 45 °C, stored in polypropylene plastics, zipper bags and plastic boxes. Quality parameters were evaluated every 5 days and based on phytochemical changes such as vitamin C, polyphenol, and antioxidant activity. Results revealed that polypropylene plastics were the best packaging product for retention of vitamin C content (5.837 mg/100g) antioxidant activity (7.458%) and phenolic compounds (2526.603mg/100g) after 30 days of storage. Figures for plastic boxes were 5.641 mg/100g, 5.249% and 2361.657 mg/100g, respectively. Similarly, zipper bags were 5.32 mg/100g, 5.895 % and 2173.867 mg/100g respectively. Sensory evaluation in terms of taste, color, texture, and overall acceptability showed that polypropylene packaging gave favorable scores and the products were highly accepted by trained evaluators.

Rational Composition

In the production technology of bakery products for the enrichment of products useful for the human body substances use a number of components. Many of them significantly increase the nutritional and consumer value of bread. An important area of research should be the identification of optimal ratios of wheat flour with other components to obtain products with increased antioxidant activity. Studies have been conducted with the aim of determining the rational composition of a mixture of wheat flour of the highest grade and flour made from grain of naked pigmented barley of the variety Granal 32, which has increased antioxidant activity, for use in the production of bread. For research used options with the addition of wheat flour of the highest grade barley in the amount of 10, 20, 30, 40%. The results showed that in flour mixtures as the barley flour component increased, the gluten content decreased. The quality of gluten was characterized by a tendency to increase elasticity. In mixtures with the maximum content of barley flour (30 and 40%), the protein content is reduced relative to the control and the previous variants. The strength of the flour decreased, starting with the variant with the amount of barley flour of 20%. The tendency to decrease in the values ??of indicators in the variants with the barley flour component was also observed when evaluating the physical properties of dough on the farinograph. The quality number of the farinograph decreased in the variant with the inclusion of 10% barley flour by 35, and in the subsequent ones - by 56–67. The volume of bread and the total bakery grade were less reduced in the variant with the addition of barley flour in the amount of 10%. Indicators of moisture and acidity of bread in this embodiment were slightly different from those of the control (without the addition of barley flour). The variant with the addition to wheat flour of the highest grade of 10% wholemeal flour from grain of naked pigmented barley of variety Granal 32 is recommended for use in breadmaking with the aim of enriching wheat flour with highly nourishing barley flour with enhanced antioxidant activity.
