HT-800 is a low pH tolerated Heat-stable Alpha-Amylase produced from selected strains of Bacillus licheniformis through submerged fermentation and refining extraction processes. HT-800 is an endoamylase which can rapidly decrease the viscosity of gelatinous starch solutions by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1,4 glucosidic bonds to produce soluble dextrins and oligosaccharides.
As a robust Alpha-Amylase with superior thermal stability, HT-800 has found its wide application in the production of starch sugar.
Declared Enzyme: Alpha-Amylase
Systematic Name: EC 184.108.40.206, 1,4-α-D-glucan glucanohydrolase
Activity: 80,000 U/ml (Minimum)
Appearance: Sepia brown Liquid
Product pH: 5.0 to 7.0
Specific gravity: 1.10 to 1.25 g/ml
Effect of pH:
HT-800 can work at pH ranging from 5.0 to 7.0 with its optimal pH range from 5.4 to 6.0. The exact pH optimum depends on the actual processing conditions, including temperature, substrate concentration and reaction time.
Effect of temperature:
For interval liquefaction process, the optimum temperature of HT-800 is above 90°C. It liquefies starch substrates promptly at 95 to 97°C and maintains highly active at 100°C. For consecutive liquefaction process, HT-800 demonstrates exceptional thermal stability at temperatures from 105 to 110°C.
Packaging, Storage & Shelf-life.
HT-800 is packaged in 25kg, 30kg food-grade HDPE plastic drums.
Typical shelf-life is six months if this product 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.
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.
Use of HT-800 can benefit the production of starch sugar as following: -Superior stability with low pH. -Decrease viscosity of starch quickly.-Eliminate undesirable color substances and non-fermentable sugars.-Effective liquefaction of various starch materials, such as tapioca, corn, wheat, rice, etc. -Superior performance without adding calcium ion under majority processing conditions.
