Beta-amylase
One.Product presentation
This enzyme is also called High Malt-sugar Enzyme.It is a new product produced according to the new demand of producing high malt sugar for enzyme.It is made in the base of Barley Beta-amylase.After it is improved,it’s activity is obviously improved,and the glucose concent is less.what’s more,it can improve the sugar productivity in the production of malt sugar.

Three.Define of activity
In the standard condition of pH 5.8,Temp 60℃,One enzyme activity unit is defined as grams of the malt sugar in condition that one gram enzyme powder decomposed 1 percent soluble starch every hour to get malt sugar.
Four.Using methods
In the process of mlat sugar production,this enzyme is mixed with water as per the proportion of 1:5,and it is dipped in 60 degrees water about thirty minutes.After material is liquefied,you can adjust the pH of solution of corn starch to 6.0 and rice to 5.8,and then this enzyme is added once and stir when the solution temperature is lowed to 60,and keep the temperature to liquefy the solution.100-150 unit enzyme can be added in each gram material(100-150 unit this enzyme per gram raw material).
In the process of beer production,this enzyme is added as per the quality of barley malt.The proportion of barley malt and raw material is 6:4 or 5:5.The mixed proportion of this enzyme and water is 1:5,and it is dipped in 30 degrees water about thirty minutes.Further,this prepared enzyme is once added in the material solution and keep the temperature to liquefy the starch solution.250-300 unit enzyme should be added in each gram material(250-300 unit this enzyme per gram raw material).
Five.Storage condition
Incide pack is innoxious plastic bag:1 kg per bag.External pack is paper box:20 kg per box.
This product must be put in the dry and cool place.It can be kept about 12 months below 10 degrees.It can be well kept six months below 25 degrees,which the activity is over 95 percent.
