  • HT-800 is low pH tolerant Heat-stable Alpha-Amylase produced from selected strains of Bacillus licheniformis using submerged fermentation and refining extraction technology.
  • As an endoamylase, HT-800 can quickly 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.
  • HT-800 is a robust Heat-stable Alpha-Amylase specially designed for the production of starch sugar.



  • For interval liquefaction, the optimum temperature of HT-800 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-800 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.



  • HT-800 is active with pH range 5.0 to 7.0, depending on the application.
  • For maximum activity, the optimal pH for HT-800 is 5.4 to 6.0.
  • The exact pH optimum depends on actual processing conditions, including temperature, substrate concentration and time.



  • For industrial application of one-time spray liquefaction, first prepare 30 to 35% w/w starch slurry, adjust pH 5.4 to 6.0, then add this product at a dosage rate of 0.10 to 0.35 kg/TDS. Liquefy at 105 to 107°C for 5 to 7 minutes, flash cooling down to around 97°C, keep on liquefying at temperature above 95°C for 90 to 120 minutes so as to reach required DE value. In case the starch content is above 35%, recommended dosage rate is from 0.35 to 0.4kg/TDS.
  • Exact dosage rate depends on the actual situation such as starch substrate, liquefaction equipment, processing conditions, etc. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product.

  • The presence of calcium increases the thermal stability of HT-800.
  • This enzyme requires a very low calcium concentration of 20 to 50 ppm (dry solids basis) to ensure its enzyme stability.




  • Copper, titanium, and cobalt ions are moderate inhibitors for HT-800.
  • Aluminum, lead and zinc ions act as strong inhibitors.

  • 1125kg IBC totes

Storage &Shelf-life :

  • 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.
