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 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.
