DESCRIPTION

Heat-stable Alpha-amylase HT-2400 is derived from non-genetically modified strains of Bacillus licheniformis by submerged fermentation and refining extraction.

HT-2400 is an endoamylase, which rapidly decreases the viscosity of a gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the α-1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides. It can be applied without adding calcium ions during liquefaction process of production.

As a very robust alpha-amylase with low pH tolerance, HT-2400 is widely applicable to the production of starch sugar and brewing.

PRODUCT CHARACTERISTICS

PH & TEMPERATURE PROFILE

• HT-2400 is active with pH range 5.0 to 7.0, the optimal pH is 5.4 to 6.0.
• For interval liquefaction, the optimum temperature of HT-2400 is above 90°C.
• It liquefies starch substrates promptly at 95 to 97°C and maintains highly active at 100°C.
• For consecutive liquefaction, HT-2400 demonstrates exceptional thermal stability at temperatures up to 105 to 110°C , maintain its stability for 5 to 7 minutes, keep on  rapid and complete liquefaction.

USAGE GUIDELINE

• In general, first adjust the pH to 5.4-6.0 and then add calcium 20 to 50 ppm before adding HT-2400. Calcium is not needed when tap water is used. After the enzyme is added, heat the slurry to liquefy.
• Dosage of HT-2400 depends on the actual situation such as starch, substrate concentration and other processing conditions.
• 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 0.03 to 0.08kg/TDS.

PACKAGING

• HT-2400 is packaged in 25kg cardboard drums or kraft paper bags.
• Customized packaging is available upon request.

STORAGE

• HT-2400 has been formulated for optimal stability.
• Typical shelf-life is six months provided being stored below 25°C (77°F) in its original packaging, sealed and unopened, protected from the sunlight.
• Its shelf-life is eighteen months if it is stored properly at 0～10°C(32～50°F).
• Prolonged storage and/or adverse conditions such as higher temperatures may lead to higher dosage requirement, thus 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.
