Product Description

Chymosin (CAS No.9001-98-3, EC No. 3.4.23.4) is derived from the Kluyveromyces lactis strain.

It’s a food grade enzyme which produced from submerged fermentation. This product is mainly

used in cheese processing, which can make milk clotting.

Action Principle  

The clotting of milk by chymosin can be divided into two stages.

First, the enzyme specific hydrolysis the peptide bond in Phe105-Met106 from k-casein polypeptide chain in milk to form stable para-k casein.

Second, para-k casein, α-casein and β-casein will precipitate to form clotting with the action of Ca+2.
