Sodium erythorbate (C6H7NaO6) is a food additive used predominantly in
Alternative applications include the development of additives that could be utilized as antioxidants in general. For instance, this substance has been implemented in the development of corrosion inhibitors for metals
Sodium erythorbate is soluble in water. The pH of the aqueous solution of the sodium salt is between 5 and 6. A 10% solution, made from commercial grade sodium erythorbate, may have a pH of 7.2 to 7.9.[15] In its dry, crystalline state it is nonreactive. But, when in solution with water it readily reacts with atmospheric oxygen and other oxidizing agents, which makes it a valuable antioxidant.[6]
