Product Description


Liquid Acid Protease AP-050


Halal & Kosher Certified




  • Acid Protease AP-050 is produced from selected strains of Aspergillus niger through submerged fermentation, extraction and refining processes. It can catalyze hydrolysis of plant and animal proteins under acidic conditions. AP-050 has found its wide application in food industry, including alcohol, fermentation, brewery, beer and wine production. It is also suitable for animal feed and leather industry.

Effect of Metal Ions

AP-050 is activated by Mn2+, Ca2+ and Mg2+ ions whilst inhibited by heavy metal ions such as Cu2+, Hg2+ and Al3+.


Applications and Benefits


[Alcohol Production]

  • Use of AP-050 in alcohol production from starch materials can speed up the fermentation and uplift yields of alcohol.


[Food Industry]

  • Use of AP-050 in food industry can help to increase amino acid content of food, thus improve flavors and qualities of bread, cookies, cakes and sausages.


[Beer Production]

  • Use of AP-050 in beer production can decrease the diacetyl content, thus shorten the brewing time.


[Animal Feed]

  • Use of AP-050 can convert proteins contained in the feedstuff into peptides, hence facilitates the digestion and absorption of protein by animals.


[Leather Processing]

  • AP-050 can be used to soften leather, enable easy dyeing, full hand-feel, improve leather and fur luster.



  • AP-050 is available in 25kg or 30kg HDPE drums and 1125kg IBC totes. Customized packaging is available upon request.



  • AP-050 has been specially formulated for optimal stability.
  • 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.


Safe Handling of Enzymes:

  • Inhalation of enzyme dust and mists should be avoided. Proteins present in AP-050 may cause allergic reaction in sensitized individuals which could necessitate immediate medical attention.
  • In case of contact with skin or eyes, promptly rinse with water for at least 15 minutes.
  • For detailed handling information, please refer to the Material Safety Data Sheet.
