Product Description
Fungal Alpha-amylase is produced by submerged fermentation of Aspergillus Oryzae followed by purification and formulation. The product depolymerizes starch leading to the liquefaction of starch, viscosity reduction and contains little side activities.
Mechanism and product standard
Fungal Alpha-amylase is an endo type of α-amylase that hydrolyzes the α-1,4-glucosidic linkages of gelatinized starch and soluble dextrins randomly, reducing the high viscosity of the starch slurry, giving rise to o oligosaccharides and a small amount of dextrin.
Product standard
The product complies with GB1886.174.

Application recommendation
Maltose syrup production: 15-0.3L/t DS or syrup with maltose content below 54%.
Brewing:2-0.4L/t DS at mash-in to improve extract yield, fermentable sugar level and prevent the formation of chill haze; during fermentation 0.002-0.004L/t DS to prevent chill haze, 0.02-0.1g/t DS to reduce residual sugar level.
Bread and steamed bun applications: 002-0.01L/ton flour. often used together with Xylanase.
Attention: The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient
