FIELD: feed production.
SUBSTANCE: claimed method includes protein extraction from protein-containing raw materials, extract separation, extract treatment with acid solution (e.g., anolyte or hydrochloric acid solution) to adjust pH 2-4 and protein deposition, insoluble protein deposit separation; drying thereof using air spray drier, wherein as protein-containing raw material peas is used. Protein extraction is carried out 2-4 times with catholyte solution of pH 11-12 for 10-12 min in ratio peas/catholyte of 1/5-7 wt pts. Protein solutions in catholyte obtained after each extraction are blended and precipitated simultaneously.
EFFECT: more effective method for production of protein additive from peas due to reducing of extraction time and waste amount; increased yield of peas additive.
