1. Product Introduction
β-Amylase is a high-efficiency enzyme preparation extracted and refined from plants through a series of scientific methods. It is an exoamylase that cutsα-1 ,4 glycosidic bond, Walden translocation reaction occurs at the same time, the product is converted from α-type to β-type maltose, but it cannot act on α-1,6-glycosidic bond, the decomposition of starch will be in 1, It stops at 2-3 glucose residues before the 6-bond; therefore, the product is maltose when acting on amylose, while 50%-60% maltose is usually obtained when acting on amylopectin. It is widely used in the sugar industry where maltose is the product or intermediate product, such as beer, vinegar, high maltose syrup, and crystalline maltitol.

3. Product application
Product usage plan
Conditions of use:Temperature range: below 65°C is relatively stable, the most suitable temperature is between 55°C- 60°C.
pH range: Effective pH range is 3.0-6.5, and optimum pH range is between 5.0-5.6.
Effects of common metal ions on enzyme activity: lower concentrations of Ca2+, Mg2+ can activate, and Hg2+, Fe3+ and oxidants can inhibit enzyme activity.
Add a plan
The optimal saccharification conditions depend on saccharification time, pH, temperature, substrate concentration and enzyme dosage. Each application manufacturer should determine the best process conditions according to their own conditions. The recommended methods are as follows:
In maltose syrup (gluten) and beer brewing, 0.1-0.3L/t dry basis, saccharification under optimum conditions for 0.5-30 hours. High Maltose Syrup (>70%) : Synergistic saccharification with pullulanase is required. Suggested usage: β-amylase 0.5-1.0L/t dry basis, pullulanase 0.5-1.0L/t dry basis (enzyme activity in 1,000 units), saccharification for 24 hours.
Ultra-high maltose syrup (>90%): Need to synergize with pullulanase and maltotrisidase. Suggested usage: β-amylase 1.5-2.0L/t dry basis, pullulanase 1.5-2.8L/t dry basis (enzyme activity in 1,000 units), saccharification for 24 hours, adding maltotrisidase 1.5-2.0 L/t dry basis, continue saccharification for 24 hours (the above time and dosage are for reference only, the specific test should prevail).
