FIELD: process engineering.
SUBSTANCE: dehydrated initial protein, hydroxide of alkaline or alkali-earth metal, reaction catalyst and alcoholate of the same alkaline or alkali-earth metal are simultaneously loaded into reactor provided with mixer. Alcoholate is fed in recycling mode into reactor. Protein modification is executed by reaction of the exchange of protein with hydroxide of alkaline or alkali-earth metal followed by bonding of metal cation. Protein is separated from reaction medium to evaporate said catalyst. The product is flushed with water, product pH is adjusted by 3 M solution of hydrochloric acid to pH = 6-10, and dried.
EFFECT: product with hydrophilic and emulsifying capacity, simplified process.
