Aminopeptidase is produced by submerged fermentation of Aspergillus oryzae followed by purification, formulation and drying. The product is used for the debittering of protein hydrolysate, thorough hydrolysis of protein and preparation of bioactive polypeptide.
Mechanism and product standard
Aminopeptidase is an exopeptidase, splitting of amino acids off from N-terminal of peptide chain. The bitterness or taste of a peptide has something to do with its chain length and its amino acid composition. With the removal of amino acid from terminals, the functionality and taste of remaining peptides will change accordingly, rendering the hydrolysate desired properties. The aminopeptidase is often used together with endopeptidase.

The recommended dosage is 0.01-0.2kg/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals.Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided.If irritation or allergic response for skin or eyes develops, please consult a doctor.
