Alkaline protease

Alkaline protease is also known as 2709 protease and bacillus licheniformis protease. It is a biological enzyme preparation made by bacillus licheniformis after fermentation, culture and fermentation and refined by biotechnology. It belongs to serine endonuclease.At a certain temperature and PH value, it can hydrolyze macromolecular proteins into peptides and amino acids.Suitable for food processing, daily chemical, feed, medicine and other industries.

Consulting the telephone


Do you have this kind of problem?
  • Fake labeling

    Product labeling 100000 enzyme activity, the actual enzyme activity, 60000, caused by hydrolysis does not reach the designated position, indirectly increase the cost of using enzymes.

  • Unstable Quality

    Lack of protection technology of enzyme, enzyme activity is not stable, caused the product quality fluctuation.

  • Unsatisfying Effect

    Pertinence is not strong, the structure of the different materials is different, lead to a single monomer enzyme digestion effect, low yield, bitter taste, taste bad.

  • Long Delivery

    With no experience in enzyme and enzyme distribution technology, tests repeatedly, has led to an increased research and development costs, indirect extend the production cycle.

  • Poor Sevice

    Due to the particularity of enzyme preparation, how to use, after use, should be timely answer, but many enterprises can't timely solutions to customers.
