Документ Influence of pumpkin cellulose on conformational transformations in dough and bread from wheat flour(2023) Shevchenko, Anastasiia; Litvynchuk (Vorontsova), Svitlana; Drobot, Vira; Shevchenko, OleksandrThe aim of the present study was to determine the effect of pumpkin cellulose addition to wheat flour on conformational transformations in the structure of dough and bread. The granulometric composition, functional and technological properties, and amino acid composition of pumpkin cellulose were compared with those of premium grade wheat flour. The influence of pumpkin cellulose in combination with phospholipids on conformational transformations in the structure of dough and bread was studied by method of infrared spectroscopy in the range of near-infrared regions. It was found that 96% of the particles of wheat flour of the premium grade passed through a sieve with holes of 132 microns, the remaining 4% – through a sieve with holes of 260 microns. Pumpkin cellulose was much coarser, because all 100% of its particles remained on a sieve (hole size 670 microns). Moisture binding capacity of pumpkin cellulose was 3.6 times higher, and moisture retaining capacity was 2.8 times higher than of wheat flour due to the presence of a significant amount of fibers. The amino acid score of lysine (the limiting amino acid in wheat flour) was 0.44. The amino acid score of methionine (the limiting amino acid in pumpkin cellulose) was 3.16, and the amino acid score of lysine was much higher than in wheat flour 3.49. Partial replacement of wheat flour with pumpkin cellulose (5–15%) increased this indicator for lysine by 6.5–15.2%. It was found that infrared spectra of dough samples after kneading (control sample and sample with the partially flour replacement by pumpkin cellulose) practically overlapped throughout the range of wavelengths. During the fermentation process conformational changes of functional groups occurred intensively as well as changes in structural and mechanical properties. The dough ball of the control sample thinned faster. Shape-retaining ability improved with increasing replacement percentage of wheat flour with pumpkin cellulose. The partial replacement of wheat flour with pumpkin cellulose enhanced the biological value of bread and changed the structural and mechanical properties improving shape-retaining ability of dough but decreasing dimensional stability of bread.Документ Reduction of acrylamide formation in molded potato chips of increased nutrition value(2022) Kovtun, Alina; Kovbasa, Vladimir; Bortnichuk, Oleg; Shevchenko, Oleksandr; Duboriezov, OleksandrМетою дослідження є визначення оптимальних температурних режимів випікання-висушування картопляного тіста для зменшення акриламіду в формованих картопляних чіпсах з підвищеною харчовою цінністю. Для підвищення харчової цінності формованих картопляних чіпсів розширено традиційну сировинну базу за рахунок застосування різних висівок зернових, жмиху, харчових волокон, порошків овочів, тощо. Рекомендовані оптимальні параметри оброблення картопляного тіста при температурі 125°С та тривалості 4,5 хв без застосування рослинних олій на відміну від традиційних способів виробництва формованих картопляних чіпсів. Визначено кількість аспарагінової кислоти - 190,5 мг/1г білка і редукувальних цукрів - 0,6 % в картопляній крупці. У висівках жита та ячменю кількість аспарагінової кислоти 77,5 та 72,6 мг/1г білка, у жмиху гарбузового насіння - 80,5 мг/1г білка, у кріопорошках броколі та червоного буряка - 72,5 та72,9 мг/1г білка. Масова частка редукувальних цукрів у висівках жита та ячменю складає 0,74 та 0,8 %, у жмиху гарбузового насіння - 0,5 %, у кріопорошках броколі та червоного буряка - 0,3 та0,5 %. Отримані продукти, в яких не виявлено акриламіду за рахунок зміни класичної технології і параметрів виробництва формованих картопляних чіпсів. Досліджено, що при застосуванні класичної технології формованих картопляних чіпсів кількість акриламіду у готових виробах - 61 мкг/кг в 100 г продукту. В формованих картопляних чіпсах без додавання висівок, жмиху та кріопорошків, які випікалися-висушувалися, кількість акриламіду 9,35 мк/кг в 100 г продукту. The aim of the study is to determine the optimal temperature regimes for baking and drying potato dough to reduce formation of acrylamide in molded potato chips of increased nutritional value. In order to increase the nutritional value of molded potato chips, the traditional raw material base has been expanded using various cereal bran, meal, dietary fibers, and vegetable powders. The recommended parameters for processing potato dough are: temperature of 125°C and a duration of 4.5 minutes without vegetable oil addition, in contrast to the traditional methods of molded potato chips production. The amount of aspartic acid in potato grain is 190.5 mg/g of protein and reducing sugars – 0.6%. The amount of aspartic acid in rye and barley bran is 77.5 and 72.6 mg/g of protein, respectively, in pumpkin seed meal – 80.5 mg/g of protein, in cryopowders of broccoli and red beet – 72.5 and 72.9 mg/g of protein. The content of reducing sugars in rye and barley bran is 0.74% and 0.8%, respectively, in pumpkin seed meal – 0.5%, in cryopowders of broccoli and red beet – 0.3% and 0.5%, respectively. After addition of non-traditional materials to the recipe, products were obtained in which no acrylamide was detected due to changes in the classical technology and parameters of molded potato chips production. It was investigated that when applying the classical technology of molded potato chips, the amount of acrylamide in the finished products is 61 μg in 100 g of the product. In molded potato chips without the addition of bran, meal and cryopowders, which were baked and dried, the amount of acrylamide is 9.35 μg in 100 g of the product.Документ Trends and expected benefits of the breaking edge food technologies in 2021–2030(2021) Ivanov, Volodymyr M.; Shevchenko, Oleksandr; Marynin, Andriy; Stabnikov, Victor; Stabnikova, Elena; Gubenia, Oleksii; Shevchenko, Anastasiia; Gavva, Oleksandr M.; Salyuk, AnatolyThe review considered the major trends in the world development of new food processing technologies in 2021–2030: more strict regulations of food safety including QPCR and DNA-sequencing detection of emerging food-borne pathogens, comprehensive control of minor chemical pollutants of food; production of functional food including food for babies, children, pregnant women, elderly, for sport activities, military food, meals ready-to-eat, microelements-enriched food, nutraceuticals, and clinical food; emerging environmentally-friendly and energy-saving food processing; biotechnological food processing using enzymes proteinases, glutamine transferases, galactosidases, enzymes, microbial metabolites, and new sources of food such as insects and artificial meat; personalization of food processing and distribution including adaptation of the food processing to the nutritional needs of different customer groups.Документ Phase transitions in food production technologies(2020) Sokolenko, Anatoly; Shevchenko, Oleksandr; Vasylkivskyi, Kostyantyn; Koval, Olga; Maksymenko, Iryna; Shevchenko, AnastasiiaThe paper deals with information about the general state of technologies for the utilization of secondary energy resources and environmental resources.The analysis of isoenthalpy drying processes led to the conclusion that it is expedient to keep the total potential of the vapor-gas mixture in closed circuit, but with the feature that the drying potential of the medium will be renewable.Документ Modeling and synthesis of systems of intensive mass exchange(2019) Sokolenko, Anatoly; Shevchenko, Oleksandr; Vasylkivskyi, Kostyantyn; Boiko, Oleksii; Shevchenko, AnastasiiaThe paper analyzes the physical basis of methods and ways of intensification of processes in liquid and gas-liquid systems and phenomenological generalizations based on known laws of nature with mathematical formalization of relationships between geometric, kinematic and hydrodynamic parameters.
