Product Benefits
1. Faster fermentation;
2. Reduced processing time;
3. Capable to liquefy various starch materials;
4. Robust alpha-amylase activity enables lower dosage level.
Description
Heat-stable Alpha-amylase HS-400 is derived from a modified strain of Bacillus licheniformis using submerged fermentation and refining extraction techniques. HS-400 is an endoamylase which rapidly decreases the viscosity of a gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides.
Application
HS-400 is suitable for starch sugar, ethanol, monosodium glutamate, beer and brewing industry.

Appearance
Dark brown liquid
Effect of pH
HS-400 is active over a wide pH range, depending on the application. For maximum activity, the optimal pH for HS-400 is 6.0 to 6.4. At a temperature of 25กใ C, the stable pH range for HS-400 is 5.0 to 10.0. The exact pH optimum depends on temperature, substrate concentration , procesing time etc.
Effect of Temperature
Optimum temperature of HS-400 for interval liquefaction is greater than 90กใ C. HS-400 liquefies starch substrates promptly at 95 to 97กใ C and is still highly active at 100กใ C. This product demonstrates exceptional thermal stability at temperatures from 105 to 110กใ C, keeps its stability for 5 to 7 minutes and keeps on liquefying rapidly and completely. At temperatures above 105กใ C, the enzyme stability decreases rapidly. The exact temperature optimum will depend on many process variables, including pH, substrate concentration and reaction time.
Concentration of Calcium
The presence of calcium increases the thermal stability of HS-400. This enzyme requires a very low calcium concentration and calcium additions of 50 to 70 ppm (dry solid basis) are sufficient to ensure enz |
