Sodium Erythorbate (CAS 6381-77-7), also known as Sodium Isoascorbate or E316, is a water-soluble antioxidant widely used in food processing and related applications. It is the sodium salt of erythorbic acid and is valued for its reducing and antioxidant properties. The FDA lists Sodium Erythorbate among food substances with technical functions including antioxidant, color or coloring adjunct, and processing aid.
Sodium Erythorbate is typically supplied as a white to off-white crystalline powder. JECFA describes it as a white, almost odorless crystalline powder and identifies its primary functional use as an antioxidant.
Applications
Sodium Erythorbate is commonly used in food and beverage applications where oxidation control and color stability are important. It can help reduce oxidative changes and maintain the quality and appearance of processed products. Typical application areas include:
Its water solubility and reducing properties make it convenient for incorporation into aqueous formulations.
