DESCRIPTION
- HA-400FG is Heat-stable Alpha-Amylase derived from Bacillus licheniformis using submerged fermentation and refining extraction techniques.
- It 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 with superior thermal and pH stability, HA-400FG is applied to brewing industry such as beer and alcohol.
PH & TEMPERATURE PROFILE
- The effective pH range for HA-400FG is from 4.8 to 6.0 with its optimal pH range from 5.0 to 5.9. The exact pH optimum depends on actual processing conditions, including temperature, substrate concentration and time.
- For interval liquefaction, HA-400FG works at temperatures from 80 to 100°C with it optimum temperature range from 83 to 86°C. It can liquefy starch substrates promptly at 90 to 95ºC and maintain highly active at 100ºC.
For consecutive liquefaction, HA-400FG demonstrates its exceptional thermo-stability at a temperature range of 105 to 110ºC and keeps on liquefying efficiently for 5 to 7 minutes.
INHIBITORS
- Copper, titanium, and cobalt ions are moderate inhibitors for HA-400FG. Aluminum, lead and zinc ions act as strong inhibitors.
APPLICATION GUIDELINES
-
In general, first adjust the pH to 5.0 to 5.9, then add HA-400FG. After this enzyme is added, heat the slurry to liquefy at a temperature range of 83 to 86ºC for 90 to 150 minutes. The final DE value should be maintained at 10 to 12.
-
Dosage of HA-400FG is dependent on the actual processing conditions such as kinds of starch, substrate concentration, process temperature, pH and reaction time, etc. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. A good starting point for dosage rate is 0.4 to 0.8 kg/TDS.
