PROCESS FOR PREPARATION OF PROTEIN HYDROLYSATE FROM SOY FLOUR

摘要

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