PRODUCT DESCRIPTION
The flavor improving protease is produced by submerged
fermentation of Aspergillus oryzae followed by purification, formulation
and drying. It contains exo-peptidase activity that splits off the amino acids
from peptide chain terminals and can be used for the debittering of protein
hydrolysate or taste improvement. It can also be applied for DH increase during
protein hydrolysis or preparation of bioactive polypeptide.
