high temperature alpha-amylase

High temperature resistant a-amylase is produced by fermentation, extraction and refining of Bacillus licheniformis. The enzyme is an endonuclease with high thermal stability and pH stability, which can rapidly and randomly hydrolyze starch, soluble dextrin and oligosaccharide α-D-1,4-glucosidic bonds, making gelatinized starch viscosity Rapid decline, that is, "liquefaction", hydrolysis generates dextrin and a small amount of glucose and maltose. It is suitable for the liquefaction of starch raw materials, mainly used in starch sugar, amino acid, organic acid, alcohol and other industries.

3. Product application

Product usage plan

Starch milk concentration (%DS) ------28-35

Liquefied PH------------5.0-6.0

Injection temperature(℃)------------105-110

High temperature maintenance time (min)-----5-10

Laminar flow time (min)------------ 90-120

Enzyme dosage ((kg/tds)------- 0.20-0.30

● Product efficacy and performance
Rapid viscosity reduction: has a good effect of reducing the viscosity of the liquefied liquid
Thermal stability: when the spray temperature reaches 110 °C, it still retains high enzyme activity
Acid resistance: pH 5.0 still has a considerable liquefaction effect, the application pH is usually 5.0-6.0
Low calcium dependence: use tap water or groundwater for production without adding calcium ions
