(57) [Summary] [Purpose] To develop a method for highly hydrolyzing proteins with enzymes. [Constitution] The protein is derived from Aspergillus oryzae, A method for producing a hydrolyzed protein, which comprises digesting with an enzyme preparation containing at least five proteases and peptidases, and then digesting with an enzyme preparation containing prolyl endopeptidase, prolidase and prolinase derived from a single microorganism. [Advantages] According to the present invention, a high degree of hydrolysis of a protein, which has conventionally required an enzymatic reaction of three or more steps, can be carried out by a two-step enzymatic reaction. |
