| Product Name | Chymosin |
| CAS No. | 9001-98-3 |
Product Overview:
Chymosin (CAS No. 9001-98-3) is a food enzyme preparation produced through fermentation and refined extraction using the Kluyveromyces lactis strain. This product is primarily used in cheese processing to coagulate milk.
Mechanism of Action:
Chymosin coagulates milk in two stages:
1. The enzyme specifically hydrolyzes the peptide bond between Phe105 and Met106 in the κ-casein polypeptide chain, forming stable para-κ-casein.
2. Para-κ-casein, along with α-casein and β-casein, precipitates in the presence of Ca²⁺ to form curd.
