FIELD: food industry.
SUBSTANCE: invention relates to food industry, particularly, to production of protein product from grain raw material. Method involves crushing grain raw material with extraction of peripheral fraction. Mixing peripheral fraction with catholyte to produce grain suspension followed by separation of liquid phase of suspension. For precipitation of protein, HCl is added to separated liquid phase. Protein is precipitated for 40 minutes. Precipitate is separated by centrifugation. Obtained precipitate is washed with water to obtain a suspension of protein paste.
EFFECT: technical result of present invention consists in avoiding use of alkalis, reduction of duration and simplified process, obtaining more balanced amino acid composition protein product, product with increased food value.
