Product Description
DESCRIPTION
Thermostable alpha-amylase
is produced by submerged fermentation of Bacillus licheniformis followed by purification and formulation. In brewing the enzyme is used for adjunct
liquefaction to liquefy starch at high temperature gelatinization process to
avoid viscosity problem. The product will bring the following benefits:
l Efficient DE development
l Rapid viscosity reduction
l Low color formation
l Excellent performance with no additional
calcium requirement in most cases
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. The good thermostability of the enzyme makes it
possible to reduce viscosity of starch paste very quickly during
gelatinization.
