PRODUCT DESCRIPTION
Fungal α-amylase is produced by submerged fermentation of Aspergillus Oryzae followed by purification and formulation. The product depolymerizes starch to produce oligosaccharides and a small amount of dextrin. The product performs well in flour correction and baking industry.
MECHANISM
Fungal α-amylase is an endo type of α-amylase that hydrolyzes the α-1,4-glucosidic linkages of gelatinized starch and soluble dextrin randomly, giving rise to o oligosaccharides and a small amount of dextrin which is beneficial for flour correction, yeast growth and crumb structure as well as volume of baked products.

APPLICATION RECOMMENDATION
For baking industry: The recommended dosage is 2-4g per ton of flour.
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 volume.
SAFE HANDLING PRECAUTIONS
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
WARNINGS
Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
