PRODUCT DESCRIPTION
Glucose Oxidase SBE-01GO is produced by submerged fermentation of Aspergillus niger followed by purification, formulation and drying. The product is able to whiten flour, strengthen gluten and improve dough handling properties and is often used for various baked products.
MECHANISM
Glucose Oxidase can specifically catalyze β-D-glucose to form gluconic acid and hydrogen peroxide at the presence of oxygen, which promotes the formation of gluten network, and thereafter the dough handling properties and sensory properties of baked products.
A: C6H12O6+ O2 + H2O → C6H12O7 + H2O2
B: C6H12O6+ 1/2 O2 →C6H12O7

APPLICATION RECOMMENDATION
For baking industry: The recommended dosage is 2-40g 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.
