Product Description

Description
AP-5000 is a high concentration Acid Protease 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-5000 has found its wide application in food industries, such as alcohol, fermentation and brewery, beer and wine production.
 
Product Characteristics
Declared Enzyme:
Protease
EC Number:
EC 3.4.23.18
Appearance:
Pale brown powder
Activity:
500,000 U/g
Moisture :
≤8%
 
Effect of pH
AP-5000 can work at pH ranging from 2.0 to 6.0. For maximum activity, its optimal pH range is 2.5 to 4.0 at 40°C, with an optimum pH at 3.0 (see Figure 1).
 
Effect of Temperature
AP-5000 works best at temperatures from 30 to 50°C with 0.5% casein at pH around 3.0, and its optimum temperature is 40°C. It is unstable above 50°C and inactivated quickly above 60°C (see Figure 2).
Effect of Metal Ions
The enzyme activity of AP-5000 is activated by Mn2+, Ca2+ and Mg2+, whilst inhibited by Cu2+, Hg2+ and Al3+.
 
Benefits
Use of AP-5000 can bring the following benefits for food industry:
  • Alcohol :  Helps to speed up fermentation and uplift yields of alcohol from starch materials.
 
  • Food Processing:  Enables an increased amino acid content of food, thus improve flavors and qualities of bread, cookies, cakes and sausages.
 
  • Beer Production:  Helps to decrease the diacetyl content, thus shorten brewing time.
 
 
Packaging
AP-5000 is packaged in 20kg cardboard drums inner plastic bags or 20kg kraft bags. Customized packaging is available upon request.
 
Storage & Shelf-life
  • Avoid direct sunlight and rain during transportation.
  • The storage room should be kept clean, cool and dry, preferably with air-conditioner.
  • Typical shelf-life of this product is twelve months if it is stored below 25℃ in its original packaging, sealed and unopened, protected from direct sunlight.
