The goal of the study was to develop a biotechnological process for the production of protein concentrates via bioconversion of pea flour and whey, a secondary product of starch manufacture. Standard and special methods were used to analyze the chemical and biochemical composition of protein concentrates (amino acid, carbohydrate, and fractional) of flour, whey and protein concentrates. It was established that pea flour contains 52.28-57.05% water-soluble nitrogenous substances, 23.04-25.50% salt-soluble, 2.94-4.69% alcohol-soluble compounds, 0-0.61% of soluble glutenine, 6.67-10.40% alkali-soluble glutenine and 5.96-10.86% insoluble sclerotic substances. A mathematical model and optimal parameters of the enzymatic extraction of pea protein with a yield of 65-70% were developed. Ultrasonic exposure increased the yield of nitrogenous substances by 23.16 ± 0.69%, compared with the control without ultrasound. The protein concentrate had a mass fraction of nitrogenous substances of 72.48 ± 0.41% (Nx6.25) and a complete amino acid composition. The microbial conversion by the Saccharomyces cerevisiae 121 and Geotrichum candidum 977 cultures of starch whey which remained after protein precipitation allowed us to obtain feed concentrates from biomass and culture liquid with a protein mass fraction of 61.68-70.48% (Nx6.25). Protein concentrates positively affected the vital signs of rats and their excretory products. A technological scheme was developed to test the complex pea grain and starch whey processing under pilot conditions. pea, protein concentrate, extracts, whey, bioconversion, Geotrichum candidum, Saccharomyces cerevisiae, chemical composition, amino acid composition

Из зерна нута получены белковые концентраты пищевого и кормового назначения с массовой долей белка на сухое вещество 83,22±0,35 % и 54,22±0,46 % соответственно и сбалансированным аминокислотным составом. Protein concentrates for food and feed purposes were obtained from chickpea grains with a mass fraction of protein per dry matter of 83.22±0.35 % and 54.22±0.46 %, respectively, and a balanced amino acid composition.

The article presents the data of domestic and foreign researchers for feeding of poultry used lupin and its processed products. It’s advisable to use energy-and-protein concentrates made of legumes and cereal grain mixtures to prepare complete feeds. Lupin is one of the main sources of plant protein with unique amino acid composition. In opinion of the majority of researchers lupin containing feeds made according to technic guidance support productivity increasing of poultry growing and improve the quality of the products.

This article presents the results of a study of the amino acid composition of green protein concentrates. The technique of recalculation of formulations for the replacement of expensive protein components by the protein concentrates from green plants. The authors drafted recommendations for replacement such feed ingredients like soy, meat and bone and fish meal by cheaper green protein concentrates. According to the protein content, the soybean is proposed to replace by green protein concentrates of canola, alfalfa, fodder beet; the meat and bone meal by green protein concentrates of canola and alfalfa, fish meal by green protein concentrates of rape.
