Sodium Erythorbate Usage
Used as food antioxidants, anti-corrosion color additives?and cosmetic antioxidants. It can consume oxygen in cosmetics, reduce high-valent metal ions, transfer the redox potential to the reduction range, and reduce the generation of undesirable oxidation products. It can also be used as anticorrosive color additive.
