Документ Coping strategies of free style wrestlers of different manners of battles(Видавничий дім "Гельветика", 2023) Yevtyfiiev, Andrii; Bochkarev, Sergiy; Poliakov, Ihor; Yevtyfiieva, Iryna; Donets, Yuriy; Khirniy, SergiyPurpose: to determine psychological indicators of 14-15-year-old freestyle wrestlers of various manners of fighting in conditions of increased intensity of competitive activity. Materials and methods. The study of psychological characteristics of freestyle wrestlers was carried out in the pre competition stage at the sports base of the freestyle wrestling section of the public organization "SKVB "Kolizei"" in Kharkiv. 47 wrestlers aged 14-15 took part in the study, who were divided into conditional groups according to the criterion of fighting style: playing style (n = 13), tempo style (n = 15) and strength style (n = 19). Diagnostics of psychological parameters was carried out using: the Lazarus coping test, aimed at identifying strategies for getting out of difficult situations; the Eysenck personality questionnaire in order to determine the level of neuroticism and values of the extroversion/introversion scale, as well as the type of temperament; the Spielberg-Khanin test to identify indicators of personal and situational anxiety of wrestlers. Mathematical processing of the research results was carried out using the SPSS 23 program. The results. In the course of the analisys of the results of the coping test, it was established that the strategies of planning a problem solution (X=14.1, m=2.36) and seeking social support (X=12.3, m=2.78). Representatives of the tempo and force manner of fighting are characterized by the dominance of the confrontation strategy (X=13.3, m=2.89) and (X=12.9, m=3.84), respectively, acceptance of responsibility (X=12.1, m =2.59) and (X=13.1, m=3.55), respectively, and self-control in the tempo group of wrestlers (X=12.0, m=2.30). The study of types of temperament in wrestlers of different manners of conducting a match revealed the predominance of phlegmatics in all groups: playing style (61.5%), tempo (60.0%) and strength (52.6%). Conclusions. In the course of the study, reliable differences were found in the choice of a strategy for getting out of a problematic situation among representatives of different manners of fighting. These features should be taken into account when planning and implementing differentiated technical and tactical training of freestyle wrestlers aged 14-15 years.Документ Investigation of the influence of stabilizers on the viscosity of the recovered mixture of a hypertonic drink for athletes(Scientific Route OÜ, Tallin, Estonia, 2020) Bochkarev, Sergiy; Mazaeva, Viktoria; Ovsiannikova, Tetiana; Zviahintseva, OksanaWhen introducing plant and animal protein products, in addition to nutritional value, it is advisable to assess their physicochemical properties and technological indicators, in particular, homogeneity and consistency stability. The aim of research is to determine the effect of consistency stabilizers on the viscosity of reconstituted hypertonic drink for athletes based on flaxseed cake, sesame seeds and whey protein concentrate.The mass fraction of protein in the model dry mixture of a hypertonic drink, as well as in its individual components by the Kjeldahl method, the mass fraction of fiber – by the gravimetric method, the mass fraction of lipids – by the extraction-gravimetric method, the mass fraction of moisture – by the thermogravimetric method. The mass fraction of ash in the mixtures was carried out by the method of incineration followed by calcining the mineral residue at a temperature of 450 ... 600 °C. The effective viscosity in the reduced samples of mixtures without and with the addition of stabilizers was determined on a rotational viscometer "Rheotest 2". For the planning of the experiment and data processing, mathematical methods were applied using the Microsoft Office Excel 2003 software package.The chemical composition of individual components and a model dry mixture of a hypertonic drink for the nutrition of athletes, including the content of compounds that have a stabilizing effect on the restored product, has been investigated. It has been proved that the effective viscosity of the reconstructed model mixture in comparison with the effective viscosity of the individual components of the mixture nonaditively increases. The mutual influence of the consistency stabilizers (gum arabic (E 414) and carboxymethylcellulose (E 466)) on the val-ue of the effective viscosity of the reconstituted hypertonic drink was investigated. The developed model mixture of a hypertonic drink is recommended to be used for the development of competitive dry mixtures of hypertonic drinks of plant and animal origin for the nutrition of athletes.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 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.Документ Correction of technological characteristics of proteinfat mixture by expanding the component composition(РC Tесhnology сеntеr, 2018) Bochkarev, Sergiy; Varankina, Oleksandra; Bielykh, Iryna; Samoilenko, Serhii; Zviahintseva, OksanaThe object of research is the technological characteristics of the protein-fat mixture of increased nutritional value, depending on the addition of vegetable oil as a component. The protein-fat mixture is a mixture of dried, crushed flax seeds – 60.00±3.00 %, sesame seeds – 25.00±1.25 % and ground sunflower seeds – 15.00±0.75 % by weight of the seed mixture. One of the most problematic places in the production technology of this product is the fine grinding of raw materials, as well as the removal of the mixture from the chopper chamber due to the high viscosity of the mass. In the course of research, it is reasonable to expand the component composition of the protein-fat mixture of increased nutritional value by adding vegetable oil based on modeling and rationalizing the technological characteristics of the product. The following technological indicators of the product are identified in this research, as the effective viscosity and the separation degree of the mixture, depending on the mass fraction of added vegetable oil. Rational amount of vegetable oil in the formulation of protein-fat mixture of high nutritional value is proved. Compared with the production of protein-fat mixture without the introduction of this component, the proposed technological solution provides the ability to overcome difficulties in fine grinding of seeds, as well as the removal of the resulting paste from the chopper chamber. It is proved the necessary to use 15 % vegetable oil to obtain a protein-fat mixture with an effective viscosity and resistance to separation in accordance with the requirements of production. According to the content of flax seeds in the protein-fat mixture is 51.00±2.50 %, sesame seeds – 21.25±1.00 %, sunflower seeds – 12.75±0.60 %. The effective viscosity of the resulting protein-fat mixture is 16.0±1.5 Pa·s, and the degree of product separation is 0.20±0.01 %. Vegetable oil as a component of the protein-fat mixture improves its technological characteristics, which, in turn, simplifies the process of dosing and packaging the resulting product.Документ Development and research candies with increased biological value with protein-fat composite(Scientific Route, Estonia, 2017) Bochkarev, Sergiy; Cherevichna, Nataliya; Petik, Igor; Belinska, Anna; Varankina, Oleksandra; Zakhozhyi, Oleksandra; Ilina, Oleksandra; Shyrokova, OlenaThe composition of "truffle" cream candies enriched with polyunsaturated fatty acids of ω-3 group, sesamol and tocopherols antioxidants and plant proteins in the digestible form was developed. Cream candies contain a protein-fat composite based on flax, sesame and sunflower seeds. These products can be used both in everyday and in special nutrition of athletes, soldiers, heavy manual workers, children and young people. It was determined that the oxidative stability of the model creamy candy mass increased with the concentration of protein-fat composite in it. The positive effect of the plant supplement on taste, aroma and "mouth-feeling" sensation parameters was proved by the obtained profilogram of organoleptic quality control parameters of experimental samples of candy masses with different content of protein-fat composite. Thus, it was established that the protein-fat composite in the composition of sweets improved its organoleptic and physicochemical quality control parameters, and also increased shelf life. The development allows to increase the consumer evaluation of the quality of "truffle" cream candies and, accordingly, their competitiveness.Документ Research of quality indicators of proteinfat mixture from flax and sesame seeds for nutrition of athletes(Scientific Route, Estonia, 2019) Bochkarev, Sergiy; Belinska, Anna; Varankina, Oleksandra; Ananieva, Valeriya; Petik, Igor; Koshyl, Andrii; Yevstifieieva, Olha; Rudnieva, KaterynaThe aim of the research is to determine the microbiological stability of a protein-fat mixture of flax and sesame seeds that allows to correct its storage life. A protein-fat mixture has a high content of irreplaceable amino acids ВСАА and polyunsaturated fatty acids of ω-3group, so it may be positioned as a component of nutrition for athletes. Flax and sesame seeds, cultivated in Ukraine, were used as research materials. The product was created, based on comminuted flax and sesame seeds in ratio 1:1. There were determined organoleptic (outlook, taste, smell, color) and physical-chemical (mass share of moisture, ash, protein, fat, acidic, peroxide, anisidine number) parameters of the product. There was determined the microbiological stability of the protein-fat mixture of the increased food value for athletes nutrition after 6 months. It has been proved, that as opposite to the control sample, the protein-fat mixture of the developed composition manifests its microbiological stability by the following parameters: content of mesophilic aerobic and facultative anaerobic microorganisms, molds, yeast, bacteria of the colon bacillus group and pathogenic microorganisms. The control sample that is comminuted flax seeds doesn’t manifest at the end of the storage term any correspondence of microbiological parameters by the content of mesophilic aerobic and facultative anaerobic microorganisms, molds, and bacteria of the colon bacillus group. This regularity is explained by the presence of lignans, sesamol and sesamoline, with preservative properties in the developed product. The obtained data may be used for reasoning recipes of products, based on the protein-fat mixture and correction of the food supplements ratio in them.Документ Analysis of the influence of technological parameters of the chlorogenic acid extraction process from sunflower meal on the degree of its extraction(Технологический Центр, 2020) Labeiko, Marina; Gladkiy, Fedir; Bochkarev, Sergiy; Mazaeva, Viktoria; Litvinenko, Olena; Ovsiannikova, Tetiana; Zhyrnova, Svitlana; Sytnik, NataliaThe object of research is the efficiency of extraction of chlorogenic acid ‑ the natural antioxidant, depending on the conditions of its extraction from sunflower meal. The main problem of this issue is the fact that the extraction degree of the specified phenolic compound is influenced by many factors, such as the degree of grinding of the product, the type of raw material, the method of extraction, the nature of the solvent-extractant, the temperature and duration of the extraction process, the hydromodule in the system "raw – extractant" etc. The impact of each of these parameters requires careful consideration and appropriate research. This will determine the optimal values of the specified parameters of the extraction process and increase the efficiency of extraction of chlorogenic acid. In this work, the raw material for the production of chlorogenic acid is a meal made from sunflower seeds – a cheap second raw material of oil and fat production. Previous studies have found that a high-efficiency extractant of the specified antioxidant is a solution of ethyl alcohol with a concentration of 60 %, and the optimum temperature of the process of extracting chlorogenic acid from sunflower meal is the boiling point of the extractant. As a result of this study, the regularity of the influence on the extraction degree of chlorogenic acid of such technological parameters as the hydromodule in the system "meal – ethyl alcohol solution 60 %" (hereinafter referred to as "meal – extractant") and the duration of the extraction process were studied. Experiments to determine the dependence of the extraction degree of chlorogenic acid on the hydromodule in the system "meal – extractant" and the duration of extraction were carried out in accordance with the plan of the full factor experiment. Mathematical methods using the Microsoft Office Excel 2003 (USA) and Stat Soft Statistica v6.0 (USA) software packages have been applied for experiment planning and data processing. The dependence indicated in the paper is a quadratic function that predicts an increase in chlorogenic acid content during extraction, with an increase in the hydromodule in the "meal‑extractant" system from 1:5 to 1:10 and a decrease in the extraction time from 60 minutes up to 30 minutes. It is established that for the maximum possible increase in the extraction degree of chlorogenic acid from the meal of sunflower seeds, the optimal value of the hydromodule extraction ‑ 1:10, the duration of extraction ‑ 30 minutes. The obtained results allow to increase the extraction degree of chlorogenic acid from sunflower meal from 2.46 % to 5.58 %. This indicates the possibility of increasing the efficiency of extraction of antioxidant more than 2 times.Документ Research of influence of technological processing parameters of protein-fat base for supply of sportsmen on activity of protease inhibitors(Technology center, 2017) Bochkarev, Sergiy; Krichkovska, Lidiya; Petrova, Iryna; Petrov, Serhii; Varankina, Oleksandra; Belinska, AnnaThe object of research is the biological value of the protein-fat base for athletes, workers of heavy physical labor, military personnel, depending on the conditions of its preliminary processing. A technological audit, the purpose of which was to determine the change in the content of amino acids after enzymatic hydrolysis in samples of the protein-fat base, that had undergone pretreatment by microwave radiation, was conducted. The effectiveness of the protein-fat base pretreatment by microwave radiation was evaluated on the amount of α-amino nitrogen after enzymatic hydrolysis. Based on the analysis of the obtained data, the optimal conditions of the protein-fat base pretreatment were established: 250–350 seconds of microwave treatment time and its hydration to the 12–14 % of moisture content. Such processing will increase the biological value of the protein-fat base, namely, increase the degree of digestion and digestibility of proteins in the gastrointestinal tract.Документ Research of the oilseeds ratio on the oxidative stability of the protein-fat base for sportsmen(Technology center, 2017) Bochkarev, Sergiy; Matveeva, Tatiana; Krichkovska, Lidiya; Petrova, Iryna; Petrov, Serhii; Belinska, AnnaThe problem of improving physical performance and accelerating the course of recovery processes after physical exertion is one of the most pressing problems of medicine and sports. Nutrition is one of the main controlled factors that ensure the normal development of the body, health and quality of life. Nowadays the assortment of products is mainly expanded due to introduction of new technologies, application of new chemical compounds, development of genetic engineering. At the same time, daily food cannot provide the athlete's body with nutrients in the required amount. And, as a result, in recent years, to speed up regeneration, actively replenish spent plastic and energy resources, very often in sports use biologically active additives. One of the promising areas for improving the efficiency of athletes is the introduction in food rations qualitatively new food products that meet the needs of their body and at the same time have a long shelf life. The aim of this study is to evaluate the oxidation processes of the protein-fat basis, which can be used to organize the rational nutrition of athletes. The oxidative stability of the crushed sunflower seeds, sesame seeds, flax and mixtures was studied at various component ratios. It has been established that sesame seeds are the least susceptible to oxidation, and most of all – flax seeds. Among mixtures of seeds, the most prone to oxidation are mixtures that contain flax seeds and sunflower seeds. When adding sesame seeds to the mixture, the oxidative stability increases sharply. The optimal content (% by weight) of oil seeds in a protein-fat basis was calculated using the method of mathematical experiment planning in the software package "Statistica". The period of induction of oxidation of this mixture is 1.3–1.4 times higher than the induction period of sunflower seeds and 2.7–3.0 times higher than the induction period of flax seed. The use of such basis in food technologies, in particular the confectionery industry, opens up wide opportunities for expanding the range of specialized products for athletes.
