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 on oxidative stability of proteinfat mixture based on sesame and flax seeds for use in halva technology(Технологический центр, 2019) Belinska, Anna; Bochkarev, Sergiy; Varankina, Oleksandra; Rudniev, Vasyl; Zviahintseva, Oksana; Rudnieva, Kateryna; Bielykh, Iryna; Khosha, VadymThe analysis of the main methods of modeling the formulations of protein-fat mixtures for special purposes has been conducted. Considerable attention is paid to the choice of methods for stabilizing their lipid component from oxidative damage. The urgency of increasing the oxidative stability of the protein-fat mixtures due to natural antioxidants is emphasized. The feasibility of comprehensive studies of their effect on the stability to oxidation of the most labile biologically active substances of protein-fat mixtures is substantiated. The content of furan antioxidants in the sesame seeds of Ilona, Kadet, Boyarin varieties has been determined. The correlation between the content of free and bound sesamol (sesamolin) has been determined. The content of α-linolenic acid and tocopherols in seeds of Southern Night, Kivik, Sympatik flax varieties has been also investigated. The choice of sesame and flax varieties for the creation of protein-fat mixture for special-purpose, which is a source of ω-3 group polyunsaturated fatty acids and antioxidants (sesamol and sesamolin), is justified. The effect of sesamolin content and moisture in the seeds of Ilona variety sesame on the oxidation resistance of its lipid component has been studied. A mathematical dependence describing such effect has been obtained. A regularity of increasing oxidation stability of sesame lipids with increasing its moisture content from 4.0 to 9.5 % has been revealed. This can be explained by sesamolin hydrolysis intensification with the release of sesamol and samin antioxidants. The stabilization effect of α-linolenic acid of flaxseed (Southern Night variety) by free sesame sesamol in the protein-fat mixture for special-purpose has been studied. It has been proved that a rational ratio of ω-3 fatty acids and sesamol has a significant effect on the inhibition of lipid oxidation of the protein-fat mixture for special purposes. The content of the protein-fat mixture for special-purpose in sunflower halva at the level of 20 % has been substantiated using a sensory evaluation method. The oxidative stability, organoleptic and physicochemical quality control parameters of the product have been investigated. It has been determined that the oxidation stability (and, accordingly, the predicted shelf life) of model samples of sunflower halva depend on the content of protein-fat mixture in them.Документ Research of rheological properties of mayonnaise sauce with grape skin powder(Полтавская государственная аграрная академия, 2017) Ananieva, Valeriya; Varankina, Oleksandra; Bielykh, Iryna; Samoilenko, Serhii; Zviahintseva, OksanaВизначено залежності реологічних показників якості майонезного соусу з порошком шкірки винограду від концентрації комплексного загусника некрохмальної природи.
