Abstract: The present invention provides a process for the preparation of protein hydrolysate from soy flour, which comprises preparing an aqueous slurry of defatted soy flour having 6–12% w/v of solid content, hydrolyzing the slurry using fungal protease at pH 7–8 and temperature 43±5° C. to get 20–40% degree of hydrolysis (DH), further hydrolyzing using papain at a temperature of 53±5° C. under stirring till completion of hydrolysis to 30–45% DH, inactivating residual enzyme in a known manner, and separating the solids and drying the clarified supernatant thus obtained to get protein hydrolysate.

Abstract: A process for preparation of protein hydrolysate from soy flour. The process comprises the steps of hydrolyzing an aqueous slurry of defatted soy flour containing 6-30% solid content w/v using proteolytic enzyme of plant origin at a pH of 5-9 and at a temperature of 53±5° C. under stirring for 30 minutes to 6 hours; inactivating the enzyme by a known manner, neutralizing the pH value of the slurry, separating the solids by a known manner, and drying the clarified liquor so obtained to get the hydrolysate.
