what is Protease enzyme powder?
Protease enzyme powder is one of the proteolytic enzymes. White to light yellow powder. The main function is to break down proteins into peptones, peptides, and amino acids. The most suitable temperature is 45 ℃. The optimal pH value is 2.5. When trace amounts of copper or manganese ions are present, they have a strong activating effect, while silver and mercury ions have inhibitory effects. Used as a beer clarifying agent to improve beer storage time and cold resistance. It is also used as a clarifying agent for fruit wine and a meat conditioner. Produced by deep fermentation of Aspergillus niger.

What are the use of Protease enzyme powder?
|
|
In the brewing of vinegar, soy sauce, yellow rice wine, Baijiu and other foods, the use of Protease Enzyme Powder has a significant role in promoting more robust growth of bacteria, improving the saccharification and fermentation capacity of koji, and can achieve the role of improving the utilization of raw materials and improving the flavor. Recommended dosage is 0.15-0.2L (kg)/t of raw material (enzyme activity is calculated as 100000 units), added at the beginning of koji making or fermentation. In the process of wool reduction and refinement, acidic protease can destroy the scales on the surface of wool fibers, making wool less prone to felting and more conducive to dyeing.
