  • Applications

    Sodium ascorbate, the sodium salt of ascorbic acid, is widely used as an antioxidant and reducing agent across several industries. In food processing, it acts as an antioxidant and preservative, helping to prevent oxidation and preserve color, and serves as a vitamin C source in formulations. In meat curing, it is commonly used with nitrites to accelerate curing, stabilize cured color, and reduce nitrosamine formation. In cosmetics and personal care, it is used as an antioxidant and vitamin C source to stabilize formulations. In pharmaceuticals, it provides nutritional vitamin C and can function as a formulation stabilizer to protect other ingredients from oxidation. In agriculture/animal feed, it may be used as a feed additive to supply vitamin C and protect feed ingredients from oxidative damage.
