Product Introduction
β - Amylase (EC 3.2.1.2) is an exonuclease that, when acting on starch, can hydrolyze α - The non reducing end of a 1,4-glycosidic bond sequentially cleaves a maltose unit to produce maltose and macromolecules α - Boundary dextrin. Due to the Walden inversion reaction that occurs when the enzyme acts on the substrate, the product is transformed from α- Type change to β- Type maltose.

Application area 
Mainly used in the sugar industry for beer, high maltose syrup, crystalline maltose, and other starch based raw materials using maltose as a product or intermediate.

Product characteristics
Enzyme activity: 100000 U/g
Optimal operating temperature range: 55C; Effective temperature range: 40~60 ° C
The optimal pH range: 5.0~5.5; Effective pH range: 4.5~6.2
Definition of enzyme activity: The amount of enzyme required to hydrolyze 1% soluble starch at pH 5.5 and temperature 60 ° C per hour to produce 1mg of reducing sugar (calculated as maltose) is one enzyme activity unit, expressed in 1 U.

Instructions for use
★ Maltose production: After obtaining a liquefied liquid with a DE value of 12-16 during the liquefaction stage, the enzyme dosage is added at a rate of 1.0-1.5kg/t (dry matter) under conditions of 50-55 ° C, pH 5.0-5.5, and saccharification is carried out for 20-30 hours to obtain maltose products with a DE value above 55. (It is also possible to adjust the amount of enzyme added and the saccharification time according to the actual production situation, and add pullulanase MAX P-1000 to obtain high maltose syrup and ultra-high maltose syrup.)
★ Beer production: Enzyme dosage is added at a rate of 2.5-3.0kg/t (dry matter), barley malt and auxiliary materials are added at a rate of 6:4 or 5:5, enzyme and water are added at a rate of 1:5, soaked in 50 ° C warm water for 30 minutes, and added at once, stirred evenly, and saccharified. (Enzyme addition can be adjusted based on the quality level of barley malt)
