Neutral Protease

 

Neutral protease is extracted from Bacillus subtilis through fermentation and belongs to the class of endopeptidases, which can be used for various protein hydrolysis treatments.

 

Proteases can be classified into acidic proteases, alkaline proteases, and neutral proteases based on their optimal pH values, with neutral protease being the first to be produced industrially.

 

When used as an industrial enzyme preparation, it offers advantages such as fast catalytic reaction speed, mild reaction conditions, and no industrial pollution, resulting in high demand for its applications.

 

It can function under mild conditions at a pH range of 6.0-8.5 and can be widely used in the hydrolysis of animal and plant proteins to produce HAP and HVP for high-grade seasonings and food fortifiers. In addition, it can also be used in leather dehairing and softening, and degumming of wool and silk.

1. High-Efficiency Catalysis
It can significantly improve protein digestion and absorption rates, reducing resource waste. It exhibits excellent biological activity, solubility, and emulsifying properties.

 

2. Safe and Environmentally Friendly

• This enzyme preparation is of biological origin and meets food-grade and pharmaceutical-grade standards.
• Neutral protease reduces industrial pollution.

 

3. Versatile Applications
Its mild operating conditions are suitable for various production scenarios, avoiding corrosion of equipment caused by strong acids/bases.

 

4. Activation and Inhibition
Ca²⁺ and Mg²⁺ promote enzyme activity, while chelating agents such as EDTA can inhibit activity.

 

5. Cell Integrity
Neutral protease primarily hydrolyzes non-collagen proteins in the extracellular matrix, preserving cell membrane integrity and avoiding excessive damage to the cell surface structure.
