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 Brewing]

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


[Leather Processing]

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



Effect of pH

  • The effective pH range for AP-050 is 2.0∼6.0. Its optimum pH range is 2.5∼3.5. See Figure 1.

Effect of Temperature

  • AP-050 can work at 30°C∼65°C, with an optimum temperature range 40oC∼50°C. The exact temperature optimum depends on actual processing time, pH,  nature and concentration of substrates. See Figure 2.

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




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


Storage & Storage

  • 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.
