Overview

Midrange-Thermal-Stable Amylase by Bacillus subtilis fermented and extracted amylase preparation technology refined and refined. The hydrolysis of starch grow out short and fine and small amounts of low molecular carbohydrates, glucose and maltose enzyme, so that the starch and viscosity decreased rapidly. Mainly used in textile desizing, desizing process is especially suitable for not high temperature resistant silk, chemical fiber cotton fabric. Widely used in starch sugar, alcohol, monosodium glutamate, beer, as well as feed, textile printing and dyeing desizing etc...

The application reference

1 Textile Industry: Using liquid amylase refined as desizing agent, desizing process is suitable for not high temperature resistant silk, chemical fiber, cotton fabric, the amount of enzyme in 0.2% (2000u/g), in 50-80 degrees Celsius water bath for 20-40 minutes. 

2 Fermentation industry: Starch concentration was 16-17B, pH and 6.2-6.4, and adding 0.2% calcium chloride (according to the raw material weight), and then add the starch amylase (enzyme in 6-8 units per gram of material), after mixing, heating to 85-90 degrees Celsius, liquefaction in 30 minutes. 

3 Beer production: Use rice, corn as materials when the first through 40 mesh sieve powder, paste in the paste pot with amylase, enzyme amount to 6 units / g of raw materials, at the temperature of 85-90 degrees Celsius liquefaction in 30 minutes.
