Heat stable Alpha-Amylase HT-0400 is a powder enzyme preparation derived from selected strains of Bacillus licheniformis through submerged fermentation and refining extraction process. It is an endoamylase which can rapidly decrease the viscosity of gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1, 4 glucosidic bonds to produce soluble dextrin and oligosaccharides.
HT-0400 is generally applicable to food industries including the production of starch sugar and brewing.
EFFECT OF TEMPERATURE
For interval liquefaction, the optimum temperature of HT-0400 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-0400 demonstrates exceptional thermal stability at a temperature range from 105 to 110°C, maintains its stability for 5 to 7 minutes and keeps on liquefying efficiently.
EFFECT OF PH
HT-0400 is active over a wide pH range, depending on the application. The effective pH range is 5.2～6.5. For maximum activity, the optimal pH for HT-0400 is 5.4 to 6.0. The exact pH optimum depends on actual processing conditions, including temperature, substrate concentration and time.
Copper, titanium, and cobalt ions are moderate inhibitors for HT-0400 whereas aluminum, lead and zinc ions act as strong inhibitors.
CONCENTRATION OF CALCIUM
The presence of calcium increases the thermal stability of HT-0400. A very low calcium concentration 20 to 50 ppm are sufficient to ensure the enzyme stability.
HT-0400 is packaged in 25kg cardboard drums or kraft paper bags. Customized packaging is available upon request.
HT-0400 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.
