Request SDS →Erythorbic Acid (CAS 89-65-6) is D-erythorbic acid (isoascorbic acid), a stereoisomer of ascorbic acid. It is widely used as a food antioxidant, including in the brewing and cured-meat industries, and as a reducing agent in photographic processing.
Frequently Asked Questions
What is erythorbic acid?
Erythorbic acid (CAS 89-65-6) is D-erythorbic acid (isoascorbic acid), a stereoisomer of ascorbic acid with molecular formula C6H8O6. This FCC-grade powder is used as a food antioxidant — including in brewing and cured meats — and as a reducing agent in photographic and chemical processing.
What is erythorbic acid used for?
Erythorbic acid is used as a food antioxidant in cured meats, beverages, and brewing, as an oxygen-scavenging preservative against oxidative spoilage, as a reducing agent in photographic and chemical processing, and as a flavor additive. RawSource supplies the FCC-grade powder for these applications.
What is the difference between erythorbic acid and ascorbic acid?
Erythorbic acid is a stereoisomer (the D-isomer) of L-ascorbic acid; the two share the formula C6H8O6 and similar reducing/antioxidant chemistry but differ in stereochemistry. Erythorbic acid is widely used specifically as a food antioxidant and processing reductant. Specify by CAS 89-65-6 to ensure the correct isomer.
What does FCC grade mean for erythorbic acid?
FCC indicates the material conforms to Food Chemicals Codex specifications, the purity and identity standard used for food-grade ingredients. This grade is supplied as a powder (Pdr) with a lot-specific Certificate of Analysis documenting compliance. Request the CoA to confirm specifications for your application.
How is erythorbic acid supplied in bulk?
RawSource supplies FCC-grade erythorbic acid powder (CAS 89-65-6) to food, beverage, and processing manufacturers in bags, drums, and bulk formats under HS 2932.20. Packaging, MOQ, and grade are confirmed at quotation against the CoA. Submit a bulk RFQ with your required volume.
