Abstract:

The hydrolysis of milk protein by different enzymes was studied by with DH, nitrogen soluble index (NSI) and peptide content as indexes. The results showed that milk protein can be hydrolyzed well enough by alkalizyme, prozyme A and Protamex. Moreover, the bitterness of the hydrolysate by prozyme B or pepsin is weaker than that of hydrolysate by other enzymes.

Key words: degree of hydrolysis (DH), nitrogen soluble index(NSI), enzyme, milk, milk powder, oligopeptide, protein
