Product Name: Acid Protease

CAS No.: 9025-49-4

EINECS: 232-796-2

Description:

Acid protease means that the protease has a lower optimal pH, rather than that the acid group exists in the active site of the enzyme. The optimal pH of acid protease ranges from about 2 (pepsin) to about 4. From the analysis of enzyme activity pH curve, there are one or more carboxyl groups in the active site of the enzyme. Pepsin is the most thoroughly studied protease in this class.

Acidic protease is refined from the fine strains of Aspergillus niger, which can be hydrolyzed effectively under low PH conditions. It is widely used in alcohol, Baijiu, beer, brewing, food processing, feed addition, leather processing and other industries.

Main application 

1. Baijiu industry:

This product uses starch as raw material for the production of alcohol and liquor industry. It improves the yield of wine by 0.25% wine points and improves the fermentation speed.

2. Food industry:

Starch is used in food to improve food flavor and quality, because it can increase the content of amino acids

3. Beer production:

It can effectively block the formation of diacetyl and shorten the maturity of beer.

4 feed additives:

Improve feed utilization.

5. Fur softening:

Improve the coloring rate, feel plump and increase the luster of fur.
