| Product Name | Glucose Oxidase |
| CAS No. | 9001-37-0 |
Product Overview:
Glucose oxidase (CAS No. 9001-37-0, EC 1.1.3.4) is produced through deep fermentation and refined extraction using a high-quality strain of *Aspergillus niger*. This product is capable of removing glucose, deoxygenating, and sterilizing, and is widely used in industries such as gluconic acid production, flour processing, and baked goods manufacturing.
Mechanism of Action:
Glucose oxidase specifically catalyzes the oxidation of β-D-glucose into gluconic acid and hydrogen peroxide in the presence of oxygen.
Product Characteristics:
| • Temperature Range | • 20°C–65°C, optimal at 40°C–50°C. |
| • pH Range | • 4.0–7.5, optimal at pH 5.0–6.0. |
Product Properties:
| • Appearance | • Light yellow powder. |
| • Odor | • Slight fermentation odor. |
| • Standard Enzyme Activity | • 10,000 U/g. |
| • Enzyme Activity Definition | • One unit (U) of glucose oxidase is defined as the amount of enzyme required to produce 1 µmol of hydrogen peroxide per minute under specified conditions (pH 6.0 phosphate buffer, 30°C). |
Transportation, Packaging, and Storage:
| • Transportation | • Air or refrigerated sea transport. |
| • Storage | • Store in a cool, dry, and dark place (below 25°C). |
| • Packaging | • 25 kg/drum. |
| • Shelf Life | • 2 years. |
Application Methods:
1. Flour Improvement:
￮ Adding glucose oxidase to flour oxidizes the thiol groups in gluten proteins to form disulfide bonds, enhancing the dough's network structure and improving elasticity and mechanical resistance.
￮ Recommended dosage: 20-60 g per ton of flour.
2. Gluconic Acid Production:
￮ Used in the enzymatic production of gluconic acid and its salts, typically in combination with catalase.
3. Beverage Brewing:
￮ In beer production, glucose oxidase removes dissolved oxygen and converts glucose into gluconic acid, preventing beer aging and improving stability.
4. Food Preservation:
￮ Applied in juice and tea preservation, glucose oxidase removes oxygen from food products and generates hydrogen peroxide, achieving antibacterial and preservative effects.
