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

HT-800 is a low pH, high activity and high thermal stability liquefaction enzyme for starch sugar production. This enzyme is capable of reducing the viscosity of starch gelatinization products, by randomly hydrolyzing starch, glycogen and degradation products contained in alpha-D-1,4 glycosidic to produce soluble dextrins and oligosaccharides.

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.
