Glucose oxidase

Glucose oxidase (CAS 9001-37-0), also known as GOX, is an oxidoreductase enzyme that catalyzes the oxidation of glucose to gluconic acid and hydrogen peroxide.

Where is Glucose oxidase used?

• Baking: dough strengthening via in-situ hydrogen peroxide that oxidizes gluten proteins, improving handling and loaf volume
• Clean-label alternative to chemical oxidants such as bromate in commercial bread production
• Diagnostics: active enzyme in glucose biosensors and test strips for blood glucose monitoring
• Food and beverage processing: oxygen scavenger that removes dissolved oxygen to extend shelf life and prevent oxidative spoilage
• Pharmaceutical and biotech: hydrogen peroxide-generating system in antimicrobial formulations
• It is frequently utilized in enzyme-coupled assay development for research and clinical applications.

Good to know: Commercially sourced primarily from Aspergillus niger and Penicillium species. High substrate specificity is critical to measurement accuracy in medical and laboratory settings.

Commercial specifications

• Activity expressed in units per milligram or milliliter
• Food applications typically requiring compliance with FCC or Ph. Eur. monographs
