Product Description

HGA-130 is a non-GMM glucoamylase produced from controlled fermentation of classic strains of Aspergillus niger. It can catalyze the release of glucose units from the non-reducing ends of soluble dextrins by hydrolyzing α-1,4 glucoside linkages and also slowly hydrolyzing α-1,6 glucoside linkages. 
HGA-130 does not contain glucosidase, thus enables high starch-to-sugar conversion rate.
Product Characteristics
Declared Enzyme:  
Systematic Name:
EC, 1,4-alpha-D-Glucan glucanohydrolase
130,000U/ ml (minimum)
Light to dark brown liquid
Product pH:
4.0 to 4.5
Specific gravity:
1.10 to 1.15 g/ml
Effect of pH
For maximum activity, the optimal pH for HGA-130 is in the range of 4.0∼4.5. See Figure 1.
Effect of Temperature
HGA-130 can work at temperatures from 40 to 65°C with its optimum temperature range from 58 to 62°C. This product can be inactivated quickly at temperatures above 65°C and completely inactivated at 70°C. See Figure 2.
Use of HGA-130 can be beneficial to the production of starch sugar as follows:
  • Capable to handle various starchy substrates incl. corn , wheat , cassava , potato, etc.
  • Reduce saccharification time and processing costs
  • Improve saccharification efficacy
  • Increase glucose yield
Dosage Guidelines
Typical dosage of HGA-130 is at a level of 0.3∼0.6kg/TDS. The exact dosage depends on the actual processing conditions such as raw materials, temperature, reaction time, pH and the desired results of the individual plant.
Packaging, Storage & Shelf-life
  • Standard packaging is 25kg, 30kg food-grade HDPE plastic drums or 1125 kg IBC totes. Customized packaging is available upon request. 
  • Typical shelf-life is eighteen months if this product is stored below 25°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, thereore should be avoided.
Safe Handling of Enzymes
Inhalation of enzyme dust and mists should be avoided. 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 Safety Data Sheet.
