Alpha-Amylase HT-400 is derived from Bacillus licheniformis using submerged fermentation and refining extraction techniques. HT-400 is an endoamylase which can rapidly decrease the viscosity of gelatinous starch solutions by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1,4 glucosidic bonds to produce soluble dextrins and oligosaccharides.

As a very robust Alpha-Amylase and low pH stability, HT-400 is specially designed for the production of starch sugar.

HT-400 has been designed with the following benefits for the production of starch sugar:

  • Superior stability with low pH
  • Decrease viscosity of starch quickly
  • Eliminate the formation of unwanted color substances and non-fermentable sugars
  • Effective liquefaction of various starch materials, such as tapioca, corn, wheat, rice, etc.
  • Superior performance without adding calcium ion under majority processing conditions


  • HT-400 is active with pH range 5.0~7.0, depending on the application. For maximum activity, the optimal pH for HT-400 is 5.4~6.0. The exact pH optimum depends on actual processing conditions, including temperature, substrate concentration and time.


  • For interval liquefaction, the optimum temperature of HT-400 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-400 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.


  • Copper, titanium, and cobalt ions are moderate inhibitors for HT-400 whilst aluminum, lead and zinc ions act as strong inhibitors.


  • 25kg, 30kg plastic drums
  • 1125kg IBC totes
Shelf-life & Storage:
  • Typical shelf-life is six months if it is stored below 25°C in itsoriginal packaging, sealed and unopened, protected from the sunlight.
  • Its shelf-life will be eighteen-months if this product is being store properly at 0∼10°C.
  • Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided.
