Heat-stable Alpha-Amylase HA-440FG

An Ideal Enzyme for Alocohol and Brewing

DESCRIPTION

HA-440FG is a food-grade thermostable α-amylase extracted from Bacillus licheniformis by submerged fermentation and purification.HA-440FG is an endo-amylase, which can randomly hydrolyze starch, glycogen and their degradation products of α-Dmurl 1P 4-glycosidic bond into soluble dextrins and oligosaccharides, thus rapidly reducing the viscosity of gelatinized starch solution.
HA-440FG has been widely used in alcohol production because of its strong α-amylase activity and excellent thermal stability and pH stability.

EFFECT OF IONS

Copper, titanium and cobalt ions are moderate corrosion inhibitors for HA-440FG, while aluminum, lead and zinc ions are strong corrosion inhibitors.

USAGE GUIDELINES

First adjust pH to 5.0-5.9, and then add HA-440FG.After adding the enzyme, the slurry was heated and liquefied at a temperature range of 83 to 86 degrees Celsius for 90 to 150 minutes.The final DE value should be kept in the range of 10 to 12.The amount of HA-440FG depends on the actual processing conditions, such as starch substrate, application, process, substrate concentration and so on.
In order to optimize the dose rate, it is recommended to carry out several liquefaction tests before routine use of this product.The initial dose rate is 0.18-0.22 kg / day.
