High Temperature Alpha Amylase. This is a bacterial amylase that derives from Bacillus licheniformis. Because of its tolerance for high temperatures, it is widely used in the production of starch sugars such as: glucose, fructose, maltose and dextrin. Available in liquid (brown) 20,000; 30,000; 40,000 u/ml. based on starch as substrate.

Effective temperature: 55-100℃ (Optimum temperature: 80-97℃). On steam injection liquefaction, the momentary temperature can be up to 105-112℃

pH range: 4.3-8.0 (Optimum pH: 5.2-6.0 )

Mode of Action: This is an endo-enzyme that will randomly hydrolyzes α-1,4 glucosidic linkages of gelatinized starch Into soluble dextrins, thus reducing high viscosity of the starch slurry.

Uses: Starch as raw material Slurry density: 10-20 Bé scale; pH: 5.6-5.8; steam injection temperature: 108-110℃; laminar flow: 90 minutes; make DE value 5-20% liquefied solution.

Recommended dosage: 150-500 ml/ton on dry basis, based on 40,000 u/ml.
