Aminopeptidase (AP, EC, a kind of exopeptidase.


Small peptides in food industry are produced by hydrolysis of proteins, but these peptides taste bitter because of the occurrence of two much hydrophobic amino acids. Aminopeptidase can split such amino acids from peptides to decrease the bitterness of peptide products.


1. Debitter for hydrolyzed proteins

2. Aminopeptidase can be combined with protease and peptidase, cut amino acids at the N-terminal position of proteins and peptides, improve protein and polypeptide solubility, augment the flavor of hydrolyzed peptides.

3. Apply to nutrition food, health food, protein drinks and other soybean peptide products
