HEAT-STABLE ALPHA-AMYLASE HT-800 – ENZYME FOR PRODUCING MALT, STARCH SUGAR

HT-800 is derived from a strain of Bacillus licheniformis used for fermentation and refining techniques. HT-800 is an end-amylase that can rapidly reduce the viscosity of starch gelatinization products, by randomly hydrolyzing starch, glycogen and its degradation products containing alpha-D-1,4 glucosidic to produce soluble dextrins and oligosaccharides.

HT-800 is a very strong Alpha-Amylase thanks to its high thermal stability, so it is widely used to produce malt sugar.

Product characteristics:

Enzyme composition: Alpha-Amylase

Systematic name: 1,4-α-D-glucan glucanohydrolase

Potency: ≥80,000 U/ml

Appearance: liquid, clear to dark brown.

pH: 5,0～7,0

Density: 1.15 to 1.25 g/ml

Effect of pH on HT-800

HT-800 operates with a pH range of 5.0 ~ 7.0, depending on different applications.

The optimal pH of HT-800 is 5.4 ~ 6.0.

Accurate pH optimization depends on actual production conditions, including temperature, substrate concentration, and time.

Effect of temperature on HT-800

The optimum temperature of HT-800 is above 90° C. It liquefies starch rapidly at 95-97° C and maintains high activity at 100° C. For sequential liquefaction, HT-800 exhibits exceptional thermal stability in the temperature range of 105-110° C.

Preserve: The product should be stored below 25°C, away from direct sunlight. At this temperature the product has a shelf life of 6 months. If stored properly at 0 – 10°C, the product has a shelf life of 18 months.

Note: Enzyme contains enzyme dust. In case of contact with skin or eyes, rinse promptly with water for at least 15 minutes.

Usage content: from 0.1 - 0.35 kg/ton of dry starch.

However, the exact dosage of HT-800 depends on the actual situation such as: starch substrate, liquefaction equipment, processing conditions, etc. To optimize the dosage, it is necessary to conduct some liquefaction trials to find the optimal dosage suitable for each production plant.
