Sodium erythorbate (C 6 H 7 NaO 6) 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 increases the rate at which nitrite reduces to nitric oxide, thus facilitating a faster cure and retaining the pink coloring.n urban myth claims that sodium erythorbate is made from ground earthworms; however, there is no truth to the myth. It is thought that the genesis of the legend comes from the similarity of the chemical name to the words earthworm and bait.
