Description

Ascorbate Oxidase is a copper-containing oxidoreductase enzyme that catalyzes the oxidation of ascorbic acid (vitamin C) to dehydroascorbic acid. This specific biocatalytic activity is critical for controlling oxidative processes in various industrial and research applications. It is essential for manufacturers and researchers in the food, beverage, diagnostic, and biochemical research sectors who require precise enzymatic control over ascorbic acid levels.

Application

• Food & Beverage Processing: Used to remove excess ascorbic acid in fruit juices, wines, and other products to prevent browning and stabilize flavor and color.
• Diagnostic Kits & Clinical Assays: Serves as a key reagent in enzymatic kits for the quantitative determination of ascorbic acid in biological samples, pharmaceuticals, and foodstuffs.
• Biochemical Research: Employed as a tool enzyme in studies of antioxidant mechanisms, oxidative stress, and enzymatic pathways involving ascorbic acid metabolism.
• Cosmetic Formulation: Utilized to modulate ascorbic acid stability in skincare products, helping to control the release and efficacy of vitamin C.
• Pharmaceutical Analysis: Applied in quality control laboratories for the assay of ascorbic acid content in raw materials and finished drug products.
