Product Description


Acid Protease AP-520


 Cost-effective, Promote yeast growth, Enhance fermentation, Enable higher alcohol yields




  • Acid Protease AP-520 is a food grade acid protease enzyme produced from Aspergillus niger using submerged fermentation, extraction, and refining techniques. AP-520 can effectively hydrolyze proteins under acidic conditions.
  • AP-520 can be used in the production of potable alcohol, food and beverage where protein hydrolysis is needed under low pH conditions.




Declared Enzyme: Acid Protease
EC No.: EC


100,000 U/ml (minimum)

Appearance: Light brown Liquid
Product pH 3.5 to 6.0
Specific gravity 1.15 to 1.25 g/ml




  • The effective pH range for the activity of AP-520 is approximately 2.0 to 6.0, with an optimum performance at pH 2.5 to 4.0.



  • The activity of AP-520 is effective in the range from 30°C to 65°C, with an optimum performance obtained at 30°C to 50°C.
  • The exact temperature optimum will be influenced by several process variables including time, pH, and substrate nature andsubstrate concentration.



  • AP-520 is activated by Mn2+, Ca2+ and Mg2+ ions. Heavy metal ions such as Cu2+, Hg2+ and Al3+ will inhibitthe enzyme activity of AP-520.



  • In intermittent fermentations, the entire dose of AP-520 should be added all at once after the fermentation tank is filled approximately 30%. In continuous fermentations,
  • AP-520 should be added continually, with the dosage rate dependent on the amount of mash fed at the inlet of the fermentation tank.



  • The typical dosage rate for AP-520 is 0.01% to 0.02% w/w (dry solids basis) and this dosage level is recommended as a starting point for optimizing the enzyme dosage.
  • The optimum enzyme dosage will be dependent on both the raw materials used (substrate nature and concentration) and the processing conditions.


Certificate: Halal, Kosher
Package: 25kg, 30kg plastic drums or 1125kg IBC totes
Shelf-life and Storage:


Typical shelf-life is six months if this product is stored at 0∼ 10°C in its original packaging, sealed and unopened, protected from the sunlight. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided.
