Food grade thermostable alpha amylase starch hydrolysis for ethanol industry
The thermostable alpha-amylase is produced by submerged fermentation of Bacillus licheniformis followed by purification and formulation. High-temperature resistance of the enzyme makes it possible to liquefy starch and reduce viscosity while gelatinization, which brings lots of benefits for starch sugar processing and related industries. High Tempreture State Amylase, with excellent heat resistance,is widely used in the industries of starch sugar (glucose, maltose, dextrin, fructose, oligosaccharide), alcohol, beer, monosodium glutamate, brewing, organic acid, textile, print, dyeing, paper making and other Fermentation industries, etc..
DEFINITION OF UNIT
1 unit of High-Temperature α-Amylase equals to the amount of enzyme which liquefies 1mg of soluble starch to dextrin at 70℃ and pH6.0 in 1 min.

For beer industry: The recommended dosage is 0.2-0.5L of the enzyme preparation per ton of total raw materials, added at liquefaction. However, the optimal dosage depends on the composition of the raw materials and the specific process parameters and should be determined by testing different dosages at the brewery. For alcohol industry: Add this enzyme 0.3-0.6L per ton of total raw materials with pH 5.5-6.5, keep temperature at 85-90℃ for around 120 minutes. For starch sugar industry: Add this enzyme 0.4-0.5L per ton of dry starch after pH adjustment. The liquefaction temperature can reach to 100±5℃ and then keep temperature at 95-97℃ for 60-120 minutes.

Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
