    Development of the method of obtaining grain flakes using UV-irradiation
    (2023) Bazhay-Zhezherun, Svitlana; Bereza-Kindzerska, Ludmyla; Bashta (Sheremet), Alla
    The 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%

    Improving the nutritional value of grains by biological activation
    (2016) Bazhay-Zhezherun, Svitlana; Romanovska, Tetiana; Antonіuk, Mariіa
    Introduction. Cereal products are a source of carbohydrates, protein, macro and micronutrients, vitamins, enzymes, dietary fiber, phospholipids. Sprouting grains is one of the methods for biological activation. Materials and methods. Grains of wheat, triticale and naked oats have been studied. Protein was determined by Bradford method, the starch content – by poalrimetric method. Fat was determined by exhaustive extraction with chemically pure hexane. Vitamins B1, B2, B3, B6 were determined by the method of fluorometry. Vitamins PP and E were determined colorimetrically. Determination of vitamin C was performed by a titration method. Results and discussion. An important task in the process of preparing raw materials for health products is increasing their food and biological value. We proposed a regime of hydrothermal processing of grain at temperatures 12–16 °C. Under these conditions, activation of the enzyme complex, reduction of grain density and increase of its per unit volume; activation of the synthesis of vitamins and vitaminlike substance take place. In the process of biological activation of grain the bioavailability of proteins, carbohydrates, fat increases due to their partial hydrolysis. It has been studied, that the content of fibres,which is natural food sorbent, in biologically activated grains of wheat, naked oats and triticale is respectively 2,68, 2,34, 2,62%. It has been found that in the proposed processing of wheat, triticale and naked oats the quantity of vitamin C increased more than twice. The content of tocopherols increases tenfold, routine – 2,5–3 times. It was established that after hydrothermal treatment the total number of colony-forming units of mesophilic aerobic and facultative anaerobic microorganisms in native and dried corn samples is within the norms established by standards. Conclusions. The results are of practical importance, as they allow to recommend the use of biologically activated wheat, triticale, naked oats for the production of food of health, functional and health-care purposes.

    The use of the biologically activated grain is in technology of health products
    (2016) Simahina, Galina; Bazhay-Zhezherun, Svitlana; Fedorenko (Mykoliv), Tetiana; Bereza-Kіndzerska, Ludmila; Antoniuk, Maria
    The concept of scientific, methodical and technological support for learning logic is presented. The concept founds on the notions ofThe basic stages of technological process of production of semi-finished products or mixtures from grain, enriched by microelements, grounded. The mutual influence of microelements on content of amino acid in germinated grain of oat is determined. Ways of the processing enriched with mineral substances of grain raw materials it is offered. intensification of synthesis of vitamins is experimentally investigational in the process of germinating of wheat grain with the use of plant extracts that contain phytoncides. The technology of manufacturing health products is worked out on the basis of the biologically activated grain of wheat "ZerniatkoPikantne" (the kernel) with the extract of garlic or onion extract. Представлена концепція наукового, методичного та технологічного забезпечення логіки навчання. Концепція ґрунтується на уявленнях основних етапів технологічного процесу виробництва напівфабрикатів або сумішей з зерна, збагачених мікроелементами, обґрунтованих.
