What is Proteases ?
Proteases are core biological agents that catalyze the hydrolysis of proteins into peptides or amino acids, and are widely used in various fields. According to the optimal pH value, it is mainly divided into three categories: acidic proteases, neutral proteases, and alkaline proteases, which can accurately adapt to different scene requirements.
Their difference is based on difference tolerable environment, characteristic and application;
Acidic protease: The optimal pH is 2.0-4.0, represented by pepsin and Aspergillus niger protease. Only highly active in acidic environments, targeting aromatic amino acid peptide bonds, the products are mostly small molecule peptides and free amino acids. Can be used in food for cheese curd and beer clarification; Improve the protein absorption rate of young animals in feed; Used in medicine as a digestive aid.
Neutral protease: The optimal pH is 6.0-8.0, represented by the fermentation products of Bacillus subtilis, and has a wide range of sources. Neutral environment has the highest activity, partially resistant to weak acids and bases, mild hydrolysis without odor, specializing in fatty amino acid peptide bonds. Used for meat tenderization and bread improvement in food; Decompose anti nutritional proteins in feed to reduce costs; As a compound digestive enzyme component in medicine.
Alkaline protease: The optimal pH is 9.0-11.0, and the mainstream is the fermentation product of Bacillus licheniformis. Resistant to 50-60 ℃ and surfactant, with high hydrolysis efficiency. Efficient removal of blood and milk stains in detergent; The textile and leather industry assists in silk degumming and leather softening; Assisted soybean protein hydrolysis and livestock protein digestion in food and feed, and can also be used for wastewater treatment.
