product description

Acid protease is a kind of endoprotease obtained by submerged fermentation and culture of selected Aspergillus niger, and then refined and extracted by microfiltration, ultrafiltration and vacuum freeze-drying technology. Widely used in alcohol, liquor, beer, brewing, food processing, feed addition, leather processing and other industries.

mechanism of action

Acidic protease with high enzymatic activity belongs to aspartic acid and carboxyl mixed protease. Under acidic pH conditions, it can exert a strong hydrolysis ability, and decompose the protein into polypeptides or amino acids by cutting the peptide bond of the protein.

Solubility

Soluble in water, the aqueous solution is a clear light brown liquid.

application:

1. Food industry

Acid protease is often used as a starch modifier in food processing. The improved flour products are used in the production of bread, cakes, ham sausages, etc., which improves the flavor and nutritional value of the products.

2. Alcohol industry

In wine fermentation, the addition of acid protease can effectively hydrolyze the protein in the raw material, destroy the cell wall structure between the raw material particles, improve the wine yield, and at the same time increase the amino nitrogen in the mash after protein hydrolysis,

Promote the growth and reproduction of yeast

The fermentation speed shortens the fermentation cycle.

3. Feed industry

Acid protease can decompose animal or plant protein into small peptides and amino acids in a slightly acidic environment, which can supplement the deficiency of homologous enzymes in animals, enhance disease resistance, improve feed utilization, and reduce feed costs.
