Glucose oxidase is widely used in the food industry for its ability to remove glucose and oxygen, which helps in preventing spoilage and extending the shelf life of products. It is commonly applied in the production of dried egg powders, mayonnaise, beverages, bakery products, and artificial honey to maintain quality and freshness by reducing oxygen in packaging and controlling glucose levels.

In the medical field, it plays a crucial role in glucose monitoring devices for diabetes management, where it catalyzes the oxidation of glucose to produce hydrogen peroxide and gluconic acid, enabling accurate blood sugar level measurements. Additionally, it is utilized in biosensors and diagnostic kits for detecting glucose in various biological samples.

In the textile industry, glucose oxidase is employed in bleaching processes to reduce the use of harsh chemicals, making the process more environmentally friendly.

It also finds applications in the production of gluconic acid, which is used in food, pharmaceuticals, and cleaning products.

Furthermore, in the cosmetics industry, glucose oxidase is used for its antioxidant properties, helping to protect the skin from oxidative damage caused by free radicals.
