Chemical Information
FooDB NameSodium erythorbate
DescriptionAntioxidant, antimicrobial agent, appearance control agent, curing accelerator for baked goods, meat and cured meat products. Restricted use in Japan Sodium erythorbate (C6H7NaO6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it reduces the rate at which nitrate reduces to nitric oxide, thus retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines. When used as a food additive, its E number is E316.
