Erythorbic acid, also known as D-isoascorbic acid, is a food-grade antioxidant that shares the same molecular formula as ascorbic acid but with a different stereochemical configuration. It provides equivalent antioxidant functionality at a lower cost. This makes it an economical alternative for food preservation applications.
Erythorbic acid is particularly valued in the meat industry as a curing accelerator that speeds the conversion of nitrite to nitric oxide. It promotes rapid and uniform color development. It also effectively prevents oxidative browning in fruits, vegetables, and beverages. The compound has minimal vitamin C activity but delivers excellent technological performance in food systems.
