HGA-101PU contains glucoamylase and starch debranching enzyme-pullulanase. Glucoamylase is made from controlled fermentation of selected strains of Aspergillus niger. Pullulanase is made from selected strains of Bacillus licheniformis. Glucoamylase can hydrolyze alpha-1,4 glucosidic linkages from the non-reduction end of starches to release glucose. Pullulanase can specifically cleave the α-1, 6 glycosidic bond of the branching point of amylopectin, and cut out the entire branch structure to form amylose. Thus it has higher conversion rate from starch to sugar.
HGA-101PU is mainly used for the production of starch sugar.
Glucoamylase activity: 100,000U/ml (minimum)
Pullulanase activity: 800BU/ml (minimum)
Appearance: Yellow brown Liquid
Product pH: 3.0 to 5.0
Specific gravity: 1.10 to 1.25 g/ml
Effect of pH:
The effective pH range for HGA-101PU is 3.0 to 5.5. For maximum activity, the optimal pH range for HGA-101PU is 4.0 to 4.5, optimal pH is 4.2. See Figure 1.
Effect of temperature:
Effective temperature range for HGA-101PU is 30 to 65°C, normal temperature range is 55 to 65°C, optimal temperature is 60°C. It will be inactivated above 65°C. Normally, this enzyme will be completely inactivated if the saccharified liquid is boiled for 5 minutes at 80°C. See Figure 2.
HGA-101PU is packaged in 25kg, 30kg food-grade HDPE plastic drums or 1125 kg IBC totes. Customized packaging is available upon request.
The product is stored below 25°C, avoid sunlight directly.
If it is stored properly, its shelf-life will be 18 months.
Safe handling of enzymes:
Inhalation of enzyme dust and mists should be avoided. In case of contact with skins or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.
