Product Description
DESCRIPTION
Thermostable alpha-amylase
is produced by submerged fermentation of Bacillus licheniformis followed by purification and formulation. High-temperature resistance of the enzyme
makes it possible to liquefy starch and reduce viscosity while gelatinization,
which brings lots of benefits for starch sugar processing and related
industries.
MECHANISM
This product belongs to family of hydrolytic
enzyme, attacking α-1.4 glycosidic bond in starch, producing dextrin, oligosaccharides
a small amount of glucose.
