Medium temperature Alpha-amylase

Medium temperature Alpha-amylase


Introduction:                                                                                                                        

The product is obtained by deep fermentation from bacillus subtilis.It is widly used in manufacture of starch sugar and 

alchhol,brewery,textile,dye and printing, paper makinng,feed industry etc.


Mechanism:                                                                                                                        

Medium temperature amylase can hydrolyzeα-1.4 glucosidic bond of  starch molecules  ,and randomly  cut into vary

length dextrin mixed short chain and a small amount of low molecular weight carbohydrates, so that the viscosity of

 starch paste decreased rapidly, namely "liquefaction" effect, it is also called liquefying enzyme.


Product property:                                                                      

1.specification:sandy beige liquid,2000-7000u/ml;yellow powder,2000-7000u/g;white powder,1000-100000u/g(food grade).

2.Activity definition:  At the condition of 60℃ and PH 6.0,the quantity of Soluble Powder which is  liquidized 1g solid enzyme powder is the unit,in u/g(u/ml) represent.


Product Features:                                                                                                                  
 1. Temperature Range: the working temperature rang is 35-90 ℃, the optimum temperature range is 60-70 ℃.
 2..PH Range: the effective range is 4.5-8.0, and the optimum range is 5.2-6.2.
 3. Effects of metal ions on the enzyme activity: calcium can improve the stability of the enzyme, no calcium ion, the   
     enzyme activity is completely lost. In addition to external Ca2 +, Mn2 + and Mg2 + to the enzyme activity is also
     a significant role in promoting.

Application and advantages:                                                                                            
Beer,alcohol,liquefaction of  Starch, sugar, monosodium glutamate, fermentation industry,Textile Sizing,feed industry,Juice processing,Fermented bread, bread and other flour products and other products.
