Документ Development of amino acid balanced food systems based on wheat flour and oilseed meal(PC тесhnology сеntеr, 2020) Papchenko, Victoriia; Matveeva, Tatiana; Bochkarev, Sergiy; Belinska, Anna; Kunitsia, Ekaterina; Chernukha, Anton; Bezuglov, Oleg; Bogatov, Oleg; Polkovnychenko, Dmytro; Shcherbak, SergeyThe analysis of the main methods of increasing the nutritional and biological value of wheat flour has been conducted. Considerable attention is paid to the issue of adjusting the protein content in flour due to additives. The relevance of improving the amino acid composition of flour protein is emphasized. The feasibility of comprehensive studies for the development of food system formulations with a balanced amino acid composition based on wheat flour and oilseed meal is substantiated. The amino acid content has been experimentally determined and the biological value of raw materials proteins for food systems which are sunflower and soybean meal has been calculated. The mixture composition of sunflower and soybean meal with an improved amino acid composition has been scientifically substantiated. It has been found that the protein composition of the meal mixture is maximally close to the reference in terms of the content of leucine, lysine and the amount of sulfur-containing amino acids (methionine, cystine). The score of isoleucine, tryptophan, phenylalanine and tyrosine in the protein composition of oilseed meal is 1.1–1.47 times higher than the reference. The amino acid composition has been calculated and the biological value of the protein of food systems containing 80–90 % wheat flour and 10–20 % composition of soybean and sunflower meal with improved amino acid composition has been determined. It has been found that the formulation of the food system containing 20 % of the composition of meal mixture and 80 % of wheat flour has the greatest biological value in comparison with wheat flour. In this food system, the limited amino acids – lysine and sulfur-containing (methionine and cystine) are the closest to the reference one and are 67.68 % and 70.12 %. The fatty acid composition has been experimentally determined. The biological effectiveness of the fats of the developed food systems has been calculated. The closest to the fatty acid ratio recommended by nutritionists is the food system with a ratio of meal mixture: wheat flour of 20:80. The resulting formulations of food systems will be useful in technologies of flour products with high biological value.Документ Identification of patterns in the production of a biologically-active component for food products(PC Тесhnology сеntеr, 2020) Kovaliova, Olena; Tchoursinov, Yuriy; Kalyna, Viktoriia; Koshulko, Vitalii; Kunitsia, Ekaterina; Chernukha, Anton; Bezuglov, Oleg; Bogatov, Oleg; Polkovnychenko, Dmytro; Grigorenko, Natalia; Polkovnychenko, DmytroThe study reported here has established patterns in the intensive technology for making a biologically active component (the sprouts of legumes) whose germination involved natural fruit acids (citric, malic, grape). The choice of high-quality and safe stimulants is important for the germination of different grain raw materials. Such substances are the fruit acids of natural origin. Their application has made it possible to obtain a high-value component for healthy foods, namely, the sprouts of a variety of legumes. The experimental research has proven the effectiveness of using fruit acids as the effective intensifiers and disinfectants for the process of obtaining the legume sprouts. It has been shown that their use makes it possible not only to intensify the germination of legumes but also contributes to the more active formation of sprouts, and disinfects the seedbed. Thus, the use of aqueous solutions of fruit acids at the concentration of 0.25–1.25 % led to an increase in the following indicators: the germination energy, by 4–7 %; the ability to germinate, by 5–8 %; the length of the sprouts, by 3–11 mm; the weight of the sprouts, from 1 to 12 % depending on the crop. In addition, the composition of the sprouts has been investigated, which confirmed the biological usefulness and rationality of their introduction to the composition of food products as a biologically active component. The reported study has shown that they contain the elevated content of amino acids (by 3–50 % depending on the amino acid), vitamins(В1, В2, В3, В6, В12, РР, Е, С, А), the high content of protein (32 %) and extractive substances (44 %). This testifies to the biological and nutritional value of the sprouts obtained using intensive technology. The investigated technology for making legumes sprouts is innovative. The sprouts obtained can become highly nutritious components for new health food products.Документ Implementation of the plasmochemical activation of technological solutions in the process of ecologization of malt production(PC Тесhnology сеntеr, 2020) Kovaliova, Olena; Pivovarov, Olexandr; Kalyna, Viktoriia; Tchoursinov, Yuriy; Kunitsia, Ekaterina; Chernukha, Anton; Polkovnychenko, Dmytro; Grigorenko, Natalia; Kurska, Tetiana; Yermakova, OlenaThis study has established patterns in the plasmochemical activation of technological solutions in the process of malt production. Of importance is the application of innovative technologies to purify water and technological solutions used at malt enterprises that consume large quantities of water resources. A promising technology is the plasmochemical treatment of water and technological solutions in order to purify them and, partially or completely, destroy pathogenic microflora. Due to the use of plasmochemical activation, it has become possible not only to improve the malting process but also to reduce the consumption of water resources for technological purposes by 2‒3 times. This is achieved by improving the technological malting process and by the possibility of reuse of wastewater after its filtering and plasmochemical treatment. The experimental laboratory tests have proven the effectiveness of using plasmochemical activation of technological solutions in order to improve the qualitative indicators of wastewater and the possibility of reuse of such solutions after their plasmochemical activation. Applying the proposed method for treating technological solutions decreased the level of contamination of wastewater from malt production. Sewage contamination after activation decreased. Thus, pollution indicators decreased as follows: per dry residue – by 65‒95 %; the content of suspended substances – by 33‒66 %; residue after roasting – by 58‒79 %; total nitrogen – by 58‒80 %; P2O5 (phosphorus) – by 75‒88 %; K2O (potassium) – by 75‒ 92 %; CaO (calcium) – by 81‒92 %; Na2O – by 67–83 %; Cl- – not detected; oxidation – by 78‒95 %; BOC5 (biochemical oxygen consumption) ‒ by 92‒97 %; pH became alkaline. In plasmochemical treatment, there is a disinfection of wastewater, namely, during an activation mode of 60 min the phytopathogenic microflora (Aspergillus, Alternaria, Penicillium, Fusarium, Mucor) were destroyed. This indicates the effectiveness of the purification and decontamination of technological solutions. Its application is the key to the environmental safety of malt production when all its stages meet the requirements of "green" technologies.
