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. |
