Acidic Protease CAS 9025-49-4

Acidic Protease is a kind of enzyme preparation that catalyse protein hydrolysis efficiently under low pH environment (pH 2.0-4.0), usually produced by microbial fermentation such as Aspergillus niger.It is mainly used in the food industry (e.g. beer clarification, soy sauce brewing), feed processing (to improve protein digestibility) and leather treatment (hair removal and softening), and is characterised by strong acid resistance and mild conditions of action.It needs to be dried and stored at low temperature to avoid inactivation of metal ions.
