ABSTRACT
Sunflower meal, a by-product of oil production, was investigated as a primary product for protein production. Sunflower protein isolates can be used as a component of cattle diets. Integrated processing of secondary products of sunflower oil production considered includes enzyme-assisted extraction. Enzyme-assisted alkaline extracts were obtained under various conditions. The influences of temperature, pH, and type of enzyme on the degree of protein extraction were studied and the optimal conditions were determined. The process studied allows obtaining light-colored protein extracts. Ultrafiltration for concentrating and removal of low molecular weight protein fraction and carbohydrates from crude sunflower extracts was developed. The concentrates obtained were tried out as a source of nitrogen in the nutrient medium for Bacillus cereus fermentation. Solid deproteinised meal can be subjected to chemical or enzymatic hydrolysis as a medium component for heterophase fermentation to produce protein-enriched fodder additive.
