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.
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 oligosaccharides and a small amount of dextrin.

Enzyme preparations are proteins. Inhalation of dust or airborne particles may cause sensitization and trigger allergic reactions in individuals. Prolonged exposure to certain enzymes may irritate the skin, eyes, and mucous membranes. Splashing and vigorous agitation may generate inhalable dust. It is recommended to wear protective clothing, gloves, and eye/face protection.
