Документ Development of the method of obtaining grain flakes using UV-irradiation(2023) Bazhay-Zhezherun, Svitlana; Bereza-Kindzerska, Ludmyla; Bashta (Sheremet), AllaThe method of obtaining flakes of increased biological value from grain crops has been developed. This method includes preparation of grain for processing, which involves cleaning grain from impurities, sorting, airing, separation of ferromagnetic impurities, washing and disinfection, peeling, hydrothermal treatment at a temperature of 12 - 16° C. Hydrothermal treatment takes place in three cycles, each of which involves intensive moistening of the grain for 4 hours followed by dehydration for 4-6 hours with a total duration of 26 - 30 hours. After the first cycle, the grain is treated with ultraviolet radiation with constant stirring. The thickness of the grain layer is 15 - 20 cm. The wavelength of ultraviolet radiation 250 - 300 nm; radiation intensity is 200 - 260 W/m2. The distance from the grain placement plane to the radiation source is 25 - 30 cm, process duration 55 - 60 sec. The next stage is flattening of raw materials, drying of the flakes at a temperature of 45 - 65° C to a moisture of 12 - 14%, airing, packing. The main physico-chemical and organoleptic indicators of quality of wheat flakes of increased biological value are investigated. The nutritional value of the product is determined. It was investigated that the microbiological seedability of wheat flakes does not exceed the permissible values. Storage for 6 months does not significantly impair quality. The developed method of processing cereals for producing flakes allows to obtain a product with high biological value, namely, an increased content of water-soluble and fat-soluble vitamins, in particular, the content of vitamin E is 8.5 mg%, В1 - 1.12 mg%, В2 - 1.15 mg%; content of food fibers, which are natural food sorbents - 2.5%Документ Qualitative indicators of grain flakes of functional purpose(2019) Bazhay-Zhezherun, Svitlana; Simahina, Galina; Bereza-Kіndzerska, Ludmila; Naumenko, NataliiaThe influence of temperature regime and duration of cold grain conditioning on its biological value is determined. The dependence of basic physical and technological parameters of cereal flakes and organoleptic properties of finished samples of finished products on their component composition is investigated. The degree of maintenance of daily needs of the adult population in the macro and microcurrencies is determined, due to the consumption of 100 g of cereals. The indicators of microbiological stability of products are established.
