| Type:: | Enzyme Preparations | Form:: | Powder Form |
|---|---|---|---|
| Application:: | Food Addtive | Other Names:: | Alkaline Proteinase |
| Purity:: | 100% | Appearance:: | White Powder |
| High Light: | alkaline serine protease,bacterial protease enzyme |
||
Alkaline protease, also known as serine protease.Stable at pH6 to 10 and quickly inactivated below 6 or greater than 11.Because of the specificity of the enzyme, it can only hydrolyze proteins, not acting on starch, fat and other substances.The appearance of the powder is generally powder, and some are microspheres.
【Function】
1.Function mode:It can rapidly hydrolyzed protein as peptone, peptides, and eventually become amino acids.
2.Function conditions:the optimal temperature range 40°C~50°C; the optimal PH range 6.5~7.5.
3.It has a stronger effect on pelt.And the temperature of leather depilation: 36~40°C in summer;and 40~42°C in winter.It also can be stacked for leather depilation in the normal temperature.
