Product Description


Acid Protease AP-530 for Alcohol & Brewing



Halal & Kosher Certified





  • Acid Protease AP-530 is produced from Aspergillus niger through submerged fermentation and refining extraction process.
  • It can catalyze hydrolysis of proteins under acidic conditions. AP-530 is applicable to hydrolysis of proteins with acidic medium.

  Promote raw material particles dissolved

  •  AP-530 can hydrolyze the proteins of the raw materials, thus destroy the interstitial cell wall structure of starch granules, so as to release the starch wrapped in the granules, which is conducive to   saccharification.
  Beneficial to high concentration fermentation
  • In high concentration fermentation of alcohol, it is mainly nutritional deficiencies rather than the accumulation of alcohol that leads to the decrease of fermentation activity. 
  • Free amino acids (FAN) can not only shorten the fermentation cycle but also increase the output of alcohol, improve ethanol tolerance and survival rate of yeasts. 
  • Therefore, AP-530 is the best nutrient for yeast growth and accelerator for fermentation.

 Promote the growth of yeast with reproduction

  • Free amino nitrogen (FAN) is the most effective nitrogen source for yeast. 
  • Adding AP-530 during alcoholic fermentation can effectively hydrolyze proteins and peptides in the raw materials so as to generate FAN that yeasts can absorb, thus promote the growth of yeasts, increase the           quantities of yeasts in the fermented mash, and shorten the fermentation cycle.

pH Temperature Effect of Metal Irons
  • AP-530 works with pH ranges from 2.0 to 6.0 with its optimal pH from 2.5 to 3.5.
  • AP-530 can work effectively from 30 to 65°C with an optimal temperature range from 40 to 50°C.
  • AP-530 is activated by Mn2+, Ca2+ and Mg2+, and inhibited by Cu2+, Hg2+ and Al3+.




  • In intermittent fermentation, it should be added at one time when the fermentation tank is filled with one third materials.
  • In continuous fermentation, it should be added consecutively depending on the amount of saccharification mash fed at the inlet of fermentation tank.
  • 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.
