Use Of Alkaline Protease Products

Alkaline protease, also known as serine protease. There are two common types, one is Novo protease and the other is Carsberg protease, both of which are similar in nature and structure, respectively containing 275 and 274 amino acid residues (biological enzymes) and composed of a polypeptide chain. It is stable at pH 6～10, and inactivated quickly when it is lower than 6 or greater than 11. Its active center contains serine, so it is called serine protease. It can not only hydrolyze peptide bonds, but also hydrolyze amide bonds, ester bonds, and transesterify and transpeptide functions. Due to the specificity of the enzyme, it can only hydrolyze proteins, but cannot act on substances such as starch and fat. The appearance is generally powdery, and some are microspheres.

1: Leather depilation raw hides - + water washing - → degreasing - + alkali swelling - + plucking - → splitting - → dealkalization - + enzymatic hair removal - → water washing - + pickling - + tanning. Enzymatic hair removal has the advantages of simplifying the production process, shortening the cycle, improving the quality of finished products, increasing the yield of leather, reducing production costs, changing labor costs and environmental sanitation, and turning sewage into fertilizer.

2: Food processing is used in the hydrolysis of animal and plant proteins in the food industry to generate polypeptides or amino acids to form protein hydrolyzed liquids with unique flavors, which are widely used in seasoning liquids and health care products industries.

3: The daily chemical industry adds protease to washing powder, detergents and other washing products, which can greatly improve the washing and decontamination ability, especially for protein-based dirt such as blood stains, sweat stains, milk stains, oil stains, etc. It can also be used as a medical reagent to clean biochemical instruments etc., has a unique washing effect.
