Sodium erythorbate

1. Introduction of Sodium erythorbate
Sodium erythorbate is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. Sodium erythorbate is structurally related to Vitamin C and is an antioxidant. When used in processed meat such as hot dogs and beef sticks, it increases the rate at which nitrate reduces to nitric oxide, thus facilitating a faster cure and retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines.
