Compound Glucoamylase HGA-101P
Food Grade Glucoamylase/Pullulanase Compound For Starch Sugar
A food-grade glucoamylase / pullulanase compound enzyme for the
production of starch sugar, enables a greater conversion rate from
starch to glucose, suitable for the production of glucose with DX value above 96%
Use of HGA-101P ensures the following benefits for the production
of starch sugar:
- Greater conversion rate from starch to glucose
- Maximize utilization of raw materials
- Can be used in the production of glucose with DX>96%
- Stable activity ensures stable dosage rate, no need to adjust
dosage for each batch
HGA-101P contains glucoamylase and pullulanase. Glucoamylase is
made from controlled fermentation of selected strains of
Aspergillus niger. Pullulanase is made from 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
|Glucoamylase activity:||100,000 U/ml (minimum)|
|Pullulanase activity:||600 BU/ml (minimum)|
|Appearance:||Light to dark brown liquid|
|Product pH:||3.0 to 5.0|
|Specific gravity||1.10 to 1.25 g/ml|
EFFECT OF PH AND TEMPERATURE ON ACTIVITY
The effective pH range for HGA-101P is 3.0 to 5.5. For maximum
activity, the optimal pH range for HGA-101P is 4.0 to 4.5, optimal
pH is 4.2.
Effective temperature range for HGA-101P is 30 to 65℃, normal
temperature range is 55 to 65℃, optimal temperature is 60°C. It
will be inactivated above 65℃. Normally, this enzyme will be
completely inactivated if the saccharified liquid is boiled for 5
minutes at 80℃.
HGA-101P can be added into liquefied starches of substrates such as corn, wheat, barley,
tapioca, rice, potatoes, etc. and convert the starches into
Recommended optimal temperature for industrial operations is 58 to
62°C, pH 4.0 to 4.5.
First, adjust pH prior to adding HGA-101P.
A general recommended dosage rate is 0.4 to 0.8kg / TDS.The exact
dosage rate depends on the raw materials and actual processing
conditions. It is recommended to conduct several trials to
determine the actual optimal dosage rate.
HGA-101P is packaged in 25kg, 30kg food-grade HDPE drums or 1125 kg
IBC totes. Customized packaging is available upon request.
STORAGE AND SHELF-LIFE
- Typical shelf-life of HGA-101P is six months if it is stored below 25°C in its original
packaging, sealed and unopened, protected from sunlight.
- The shelf-life of HGA-101P is eighteen months if this product is
stored properly at 0 ∼10°C.
- Prolonged storage and/or adverse conditions such as higher
temperatures may lead to higher dosage requirement, therefore
should be avoided.
SAFETY & ENZYME HANDLING
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.
