Enzyme activity & typical characteristics
Activity:    **0,**0 u/g minimal
Appearance:  clear brown liquid
Solubility:   completely miscible in water
Specific gravity:  1.*5～1.*5g/ml
Activity definition: 1u/ml is defined as the amount of enzyme hydrolyzing 1.*0% starch solution to produce 1 mg maltose per hour at definite pH value and temperature. ·Application conditions
Optimal pH: 5.0– 6.8
Optimal temperature: *5℃ - *0℃
This product has good thermostability and strong catalyzing activity. The enzyme activity will increase with the rise of temperature. When the temperature exceeds *5℃, the activity decreases quickly with the rise of temperature.
Metal ion Ca2+, Mg2+ (concentration 0.*5mM—0.*8mM) can activate the enzyme. The enzyme stability will be better if with starch & Ca2+ ion together. But Metal ion Hg2+,Fe3+ and oxidant will restrain the enzyme activity.
