Product Description

Description

HA-580LFG is a high concentrated food-grade alpha-amylase produced from Bacillus licheniformis through submerged fermentation and refining extraction processes. It is an endoamylase that can hydrolyze starch, glycogen and its degradation products within the alpha-D-1,4 glucosidic bonds to produce soluble dextrins and oligosaccharides, thus decrease the viscosity of gelatinous starch solutions rapidly. Use of HA-580LFG in the liquefaction of starch materials enables lower dosage level, less storage and handling costs for the production of alcohol.

Product Characteristic

Declared Enzyme: Alpha-Amylase

Systematic Name: EC 3.2.1.1, 1,4-α-D-glucan glucanohydrolase

Activity: 400,000 U/ml (minimum)

Appearance: Sepia brown liquid

Product pH: 5.0 to 7.0 S

pecific gravity: 1.10 to 1.25 g/ml

Effect of pH

HA-580LFG can work at pH from 4.8 to 6.0, with its optimal pH range from 5.0 to 5.9. The exact pH optimum depends on the actual processing conditions, including temperature, substrate concentration and processing time.

Effect of Temperature

For interval liquefaction, HA-580LFG works at temperatures from 80 to 100°C with it optimum temperature range from 83 to 86°C. HA-580LFG can liquefy starch substrates promptly at 90 to 95ºC and maintain highly active at 100ºC. For consecutive liquefaction, HA-580LFG demonstrates its exceptional thermo-stability at a temperature range of 105 to 110ºC and keeps on liquefying efficiently for 5 to 7 minutes.

Inhibitors

Copper, titanium, and cobalt ions are moderate inhibitors for HA-580LFG; aluminum, lead and zinc ions are strong inhibitors for this enzyme.

Dosage Guidelines

First adjust pH to 5.0 to 5.9, and then add HA-580LFG. Heat the slurry for liquefaction at a temperature range from 83 to 86ºC for 90 to 150 minutes. Final DE value should be maintained at a range from 10 to 12.

Dosage of HA-580LFG depends on the actual conditions such as kind of starch, substrate concentration, processing time, temperature, pH, etc. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. A good starting point for dosage rate is 0.075 to 0.10KG/TDS.

Packaging, Storage & Shelf-life

HA-580LFG is packaged in 25kg, 30kg food-grade HDPE plastic drums or 1125kg IBC totes. Customized packaging is available upon request.
Typical shelf-life is six months if it is stored below 25°C in its original packaging, sealed and unopened, protected from direct sunlight.
Its shelf-life will be eighteen months if it is stored properly at 0∼10°C.
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, therefore 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.
