　　Brief introduction:
　　High 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, papermaking and other Fermentation industries, etc..
　　Characteristics:
　　1, Temperature range: Best operational temperature 90 oC at least, quick liquefaction in 95-97℃, stay active in 100 oC, for injection liquefaction, transition temperature can be 105-110 oC.
　　2, PH range: Effective PH range 5.5-8.0, Optimum PH range 6.0-6.5.
　　3, Calcium ion affects the active stability of enzyme: It is not sensitive to Ca2+, about 50-70ppm of Ca2+ is good enough.
　　Properties:
　　1, The definition of enzyme activity:In 70 oC, PH6.0 for 1 minute, the enzyme quantity that can turn 1mg soluble starch into dextrin is one enzyme activity unit.
　　2, Standard: QB/T2306-97.
　　Storage:
　　It is one kind of biological active matter, the strong light may be harmful to its activity, thus it should be kept in low temperature and dry place, avoid sunlight directly.
