METHOD OF PRODUCING FORAGE PROTEIN PRODUCT ON GRAIN RAW MATERIAL FERMENTOLYSAT

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to biotechnology and can be used in production of forage protein products. Method includes preparation of grain raw material (bran, substandard grain, fodder flour) by its milling to particles with size 1-20 mcm by means of mill under pressure with shift and preparation of water suspension of grain raw material with concentration of dry substances 15-16% with ratio of grain raw material and water 1:5. Carrying out fermentolysis of grain raw material by means of liquid α-amylase and glucoamylase with formation of glucose to 10-13%. Introduction of nitrogen and phosphorus sources into obtained fermentolysat; as nitrogen and phosphorus sources used are ammonium or phosphate salts or fertilisers, including ammophos, diammophos, nitrophosphate, with obtaining nutritional medium. Introduction into nutritional medium of culture-producent, as such used is strain of yeasts Saccharomyces cerevisiae Y-3585, and continuous growing in multisectional growing apparatus with supply of nutritional medium simultaneously by several sections with further concentration of suspension on vacuum-evaporator and drying. Moisture, released at stages of vacuum-evaporation and drying, is re-used for preparation of water suspension of grain raw material.;EFFECT: invention makes it possible to increase content of raw protein in finished product and simplify method of production of forage protein product.;5 cl, 7 tbl, 9 ex
