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.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 Processing of ethanol-containing waste of oil neutralization in the technology of hand cleaning paste(PC тесhnology сеntеr, 2021) Petik, Ihor; Belinska, Anna; Kunitsia, Ekaterina; Bochkarev, Sergiy; Ovsiannikova, Tetiana; Kalyna, Viktoriia; Chernukha, Anton; Ostapov, Kostiantyn; Grigorenko, Natalia; Petukhova, OlenaThe graphical dependence of the washing capacity of ethanol-containing soapstock on the concentration in an aqueous solution and the temperature of interaction with the polluted material has been determined. It is proposed to use a 40 % aqueous solution of ethanol-containing soapstock in the hand cleaning paste technology. This soapstock solution has a washing capacity of 92–98 % at the temperature of interaction with the polluted material of 25–40 °C. The regularity of the effect of the structurant content on the consistency of hand cleaning paste was investigated using an approximating polynomial. This made it possible to substantiate the effective concentration of carboxymethyl cellulose (0.4...0.6 %) and cetysltearyl alcohol (1.8...2.0 %) in the formulation. The obtained regression equation is useful for adjusting the content of structurants in the formulation, depending on the consumer's requirements for the viscosity of the developed detergent. A comparison of the quality indicators of the developed hand cleaning paste based on ethanol-containing soapstock with a sample of similar “Primaterra Automotive” commercial hand cleaning paste was carried out. The quality indicators of the developed paste are as follows: effective viscosity at 20...22 °С – 32.0 Pa∙s; foaming capacity – 23 mm, foam stability – 62.0 %; washing ability – 92.0 %. It was determined that these quality indicators do not differ significantly in the developed detergent and commercial analogue. The data obtained indicate the prospects of processing ethanol-containing soapstock into the hand cleaning paste based on natural surfactants. The developed detergent due to the content of ethanol, glycerin and hydrogen peroxide has antiseptic properties, which is a competitive advantage among analogues. Such utilization of ethanol-containing soapstock makes the process of oil neutralization environmentally safe and economically viable.
