Patent ID: 7897728

Claim:
A process for making a gelatine hydrolysate, the process comprising: (a) contacting a gelatine starting material with a series of at least three different proteolytic enzymes having endopeptidase activity to form an endopeptidase digested gelatine product, the three proteolytic enzymes being selected from the group consisting of Endopeptidase from Bacillus subtilis , Bromelain, and Papain; and (b) contacting the endopeptidase digested gelatine product with a series of at least two different proteolytic enzymes having exopeptidase activity, the two proteolytic enzymes being selected from the group consisting of Exopeptidase from Aspergillus oryzae and Exopeptidase from Aspergillus sojae, wherein the endopeptidase and exopeptidase proteolytic digestions form the gelatine hydrolysate, the gelatine hydrolysate having an average primary amine content from 1.0×10 −3 to 1.0×10 −2 μMol of primary amine per μg of gelatine hydrolysate.
