Amylase

Summary

A-amylase also known 1,4-α-D- glucan hydrolase, is refined by the submerged culture of Aspergillus oryzae Val by extraction processes. Maltose syrup is mainly used for production, it can also be used in beer, baking and other industries.

 

 

Theory

The endo-amylase enzyme may be rapidly hydrolyzed amylose and amylopectin aqueous 1,4-α- glucoside bond, produce a large number of small amounts of maltose and maltotriose, glucose and other oligosaccharides.

 

Characteristics
1, temperature range: the effective temperature range of amylase 35-65℃, the optimum temperature range of 50-60℃.
2, pH value range: effective pH range 4.5-6.0, the optimum pH range of 4.8-5.5.

3, Effect of metal ions on the enzyme activity: Ca2 + activation of the enzyme has a certain effect, Cu2 +, Ba2 +, Mn2 +, Fe2 +, Fe3 + has a strong inhibitory effect.

 

Character
1, product specifications: food grade amylase is a pale yellow solid powder, 40,000SKU/g. Solid enzyme (0.4mm standard sieve through rate): ≥80%.
2, the definition of amylase activity: 1g solid enzyme powder in 40 ℃, pH=5.0 under the conditions, the reaction 30min, to produce the equivalent amount of enzyme required to 10mg of glucose sugar reaction solution, defined as a starch enzyme activity unit.

3, product standards: implementation of industry standards People's Republic of China QB 2526-2001.

 

Application
1, in the production of maltose syrup, to produce α- amylase maltose content <54% of the syrup, the amount 0.1-0.35L / t dry matter,pH4.8-6.0, saccharification 6-30 hours at a temperature of 58-60 ℃.
2, for the beer industry, it can serve to improve the degree of fermentation, improve the rate of residual sugar, eliminate cold muddy and so on, used in the saccharification or fermentation section.
3, the chemical segment in the sugar, add the amount of 0.1-0.3kg/t dry basis can improve the degree of fermentation; increase the amount in the fermentation section 0.002-0.004kg /t dry basis may Eliminate cold mddy, plus the amount of 0.02-0.1g /t dry basis may improve the rate of residual sugar.

4, in the production process of bread, bread and other fermented foods, the enzyme may provide fermentable sugars for the yeast to make pasta uniform structure, volume Increased gas holding capacity enhancement. As recommended small amount of experimental 0.002-0.01kg / t flour (100,000 SKUof food grade enzyme activity)

 

Packaging And Storage

Solid food packaging bags, 25 kg/bucket(can be packaged according to customer requirements).

Amylase of temperature, light, humidity is very sensitive, do as much as possible during transport and storage to avoid exposure, temperature, humidity, kept clean, cool and dry, cold storage can be better.
