- ДокументTHE ROLE OF SOIL MICROBIOCENOSIS IN THE COMPOSTING OF THE ORGANIC COMPONENT OF THE MUNICIPAL SOLID WASTE(2019) G. Krusir, T. Shpyrko, О. Sagdeeva, V. ZakharchukIn order to increase the efficiency of composting the organic component of solid municipal waste as a highly effective biotechnological method, and to compare the characteristics of the processes, it is suggested to use soil as an inoculum, as a microbiological additive - an extract from the soil. The original compost mixture is a multicomponent system, the decomposition and transformation of which depends on the functioning of a microorganisms complex, in particular, fungal and bacterial microflora. Since the main component of the organic fraction is cellulose, it is expedient, along with the definition of the total number of the microflora bacterial and fungal components, to determine the number of cellulose-decomposing microorganisms. An estimation of the change in the compost mixtures’ microbial population has been made, which shows that bacteria dominate over fungi in compost mixtures. A similar microbial complex is observed in soils. The article presents the results of the study of the soil microbiocenosis qualitative and quantitative composition in order to use it as an inoculum in the process of composting the organic part of solid municipal waste. The influence of microbiological additive on the process of the organic waste composting for acceleration in mesophilic and thermophilic temperature regimes with controlled parameters was studied. The results of the conducted studies allow us to conclude that the organic waste composting with the microbiological additive is appropriate, both in the case of thermophilic and in the case of mesophilic regimes. The period of the compost maturation with the use of a microbiological additive is 6 weeks. It was shown that the microbiological complex accelerates the process of composting the organic component of solid municipal waste by 3.3 times for the thermophilic regime and by 2.1 times for the mesophilic conditions of composting process, which testifies to the efficiency of its use in the operation of the solid municipal waste processing in order to improve the general level of environmental safety.
- ДокументTHE IMPROVEMENT OF THE WATER TREATMENT TECHNOLOGY FOR THE KVASS PRODUCTION(2019) O. Dulka, V. Prybylskyi, S. Oliynyk, A. Kuts, O. KovalenkoThe composition of water significantly affect the flow of the process and the main indicators of the finished drink. The article presents the results of theoretical and experimental researches on improvement of the technology of preparation of drinking water for the production of non-alcoholic fermented beverages, in particular, bread kvass. The high efficiency of the application of natural minerals – clinoptilolite, rock crystal and activated carbon with combined treatment of water in the technology of bread kvass is proven. The quality and usefulness of the product depend on the content of its impurities. The integrated action of investigated materials with adsorption, ion exchange and redox properties provides water conditioning and achievement of the intensification of the technological process and high organoleptic qualities of the finished product. The work presents the physical-mechanical characteristics of the investigated materials, technological parameters of treatment, the influence of filter materials on the organoleptic and physical and chemical parameters of water and finished product. The article also gives a taste-aroma profile of bread kvass, made from the use of prepared water. The materials of the conducted research testify to the expediency of water treatment for the production of bread kvass in the sequence of clinoptilolite, active coal, rock crystal with a filtration rate of 8–15 m / h. In this case, the total iron content is reduced by 5 times, the total stiffness decreases by 75%, permanganate oxidation is 9 times. It has been established that such processing allows for high organoleptic qualities of prepared water and end product and increases the tasting score of bread kvass by 7 times, with no unpleasant taste and aroma that is characteristic of chlorinated water and decreases the turbidity of the beverage as a result of a decrease in the overall rigidity of water.
- ДокументUSE OF OILSEED POLYFUNCTIONAL SUPPLEMENTS IN THE MANUFACTURE OF MEAT PRODUCTS(2019) O. Topchii, Ye. Kotliar, T. Honcharenko, A. Petryna, O. TarasiukNowadays, meat production is developing towards a wider range of products. Their components are optimised and combined in such a way as to increase the nutritional value, to preserve the most valuable components of raw materials, to make for some lacking macro- and micronutrients by including the functional ingredients in the recipe. A possible way to improve the meat products technology is making purposeful changes in the formulation of the product. This involves selecting certain types of raw materials and additional components in ratios providing the required nutritional value of the finished product. New functional ingredients having the desired physiological effects on the human body should be combined with new, modern means of processing raw materials that will provide the necessary technological characteristics, the quality and safety of the final product. Home-manufactured vegetable supplements obtained from seeds of different crops are a promising direction of research. Their unique chemical composition and functional properties allow achieving the expected nutritional value of the finished product in accordance with modern nutritional standards. This article presents the results of analysing and studying of oilseeds aimed at creating a balanced multifunctional supplement to be used in recipes of functional meat products. It has been studied how the functional and technological parameters of seeds change depending on the degree of their grinding. The organoleptic evaluation has allowed determining the optimum ratio of plant components in the mixture. The quality parameters of the supplement developed, its biological value, vitamin and mineral composition have been determined. The organoleptic characteristics and structural and mechanical parameters of meat model systems have been analysed, which has made it possible to recommend the right percentage of the composite oilseed mixture in the recipes of meat products, namely, pates and chopped semi-finished products.
- ДокументTHE FATTY ACIDS CONTENT IN THE LIVER OF JAPANESE QUAILS AFTER THE CHEMICAL TREATMENT OF HATCHING EGGS(2019) V. Danchuk, V. Trach, S. Midyk, О. Danchuk, V. Ushkalov, O. KeppleThe five groups of Pharaoh quail (100 animals per group) were formed to fulfill the tasks. Quails of the control group were fed by the standard mixed fodder for quail (DSTU 4687:2006). The bird of the research groups (I–IV) received the same feed, but with the addition of 20 g/t of vitamin E. We selected the hatching eggs after 4 weeks of feeding research fodders. Eggs were weighed and laid for incubation using the standard mode after pre-incubation storage of the eggs of the quails obtained in the peak of egg production for 5 days. On the 14th day of incubation, the eggs of the quails were divided into 5 groups. Treatment of eggs I, II and III of the test group was carried out on the 14th day of incubation, respectively, with solutions of 1% sodium hypochlorite 2% perchloric acid 0,5% hydrogen peroxide. Egg of control and IV experimental group were not subject to chemical treatment. The material for research was hatching eggs of quail, liver tissue of 14 daily embryos and 1-day quail. The fatty acid composition of the lipids of tissues and egg yolk was determined in this biological material. Analysis of methyl esters of LC was carried out on a Gas chromatograph Trace GC Ultra (USA) with a flame ionization detector. Identification of fatty acids was carried out using a standard Supelco 37 Component FAME Mix. Quantitative assessment of the spectrum of fatty acids of yolk lipids was carried out by the method of internal normalization, determining their percentage content. Ontogenetic differences in the fatty acid composition of tissues are established. Processing of the eggshell on the fourteenth day of incubation with H2O2 solution is accompanied by an increase in the proportion of stearic acid in the liver of the 1-day quail and a decrease in the proportion of Neukosatrienoic and pre-fatty acids. Treatment of the shell with sodium hypochlorite and HCl is accompanied by an increase in the proportion of stearic acid by 0.96–1.00 % and аrachinic acid, with a decrease in the proportion of gondoinic and eicosatrienic fatty acids. At the same time, when treating with HCl and sodium hypochlorite, the ratio of the sum of saturated to unsaturated fatty acids decreases by 3.2–7.9% (p<0.05). So, the established changes in the fatty acid composition of the liver one-day quail indicate a significant effect of the chemical treatment of the egg shell on the exchange of fatty acids in the embryonic period.
- ДокументTECHNOLOGY IMPROVEMENT AND EVALUATION CONSUMER PROPERTIES OF DRY BREAKFAST(2019) K. Sakibaev, L. Pylypenko, T. Nikitchina, G. KasyanovThe assortment of ready-to-eat extruded products and the chemical composition of their ingredients according to the complex of basic and biologically active substances have been analyzed. The feasibility of developing new formulations of extruded breakfast cereals using non-traditional nut-bearing raw materials by means of adjusting the composition and types of leguminous and fruit components has been substantiated. The technology of multicomponent dry breakfast cereals based on wild nut-bearing raw materials of Kyrgyzstan and Ukraine, as well as cultivated types of plant crops, has been developed. The process of extrusion is improved through the use of CO2 with partial extraction of the lipid components of the raw materials. The composition of the six introduced formulations of dry breakfast cereals is substantiated by predictive forecasting of biological activity and preservation ability of the main food components after technological processing and storage of the extrudates. An increased nutritional value and a decrease in amino acids limiting the biological value of their proteins in formulations with leguminous, nut-bearing and fruit-grain components are established (formulations 1–3 − reduction in lysine deficiency by 18–26%, for methionine and cystine by 12–21%; formulations 4–6 − for lysine by 22–29%, leucine and valine by 17–36%). The absence of toxic effects and the increase in the integral biological activity of the Stylonichia mytilus test-culture in terms of its survivability by 18–31% for the developed formulations, compared with traditional extrudates, are shown. The antioxidant activity of the samples, determined volumetrically by the intensity of the isopropylbenzene oxidation, made it possible to establish the oxidation induction period and the concentration of antioxidants. According to the obtained results, the guaranteed shelf life of the developed types of dry breakfast cereals that meet safety requirements can be prolonged by 24–39% compared with the control, and the introduction of secondary raw materials to the formulations can improve technical-and-economic indicators. The nutritional and biological value, organoleptic and structural-mechanical properties, as well as the biological activity of the products developed, allow us to recommend introducing them into production.
