Product Description


Acid Protease AP-520 for Alcohol and Brewing



  • Acid Protease AP-520 is an ideal cost-effective protease that can promote yeast growth, maximize fermentation and give higher alcohol yields. It 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.

  • 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.

it is stored as recommended.
Storage at customer's
Storage Conditions Typical shelf-life is six months provided that it is stored at 0∼10°C in its original packaging, sealed and unopened, protected from direct sunlight.
This enzyme has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, therefore should be avoided

Inhalation of dust or aerosols should be avoided due to enzymes may cause allergic reactions in sensitized individuals. Avoid formation of aerosols and dust. Pick up spills by mechanical means, preferably using a vacuum cleaner equipped with a high efficiency filter. Flush remainder carefully with plenty of water. Wear suitable protective gloves, safety glasses and nose covers. In case of contact with skin or eyes, promptly rinse with water for at least 15 minutes.
