Erythorbic Acid and the Barley Free Diet

Erythorbic acid is a stereoisomer of ascorbic acid (vitamin C) and is widely used in the food industry as an antioxidant. It helps to maintain color and flavor in foods by reducing oxidation, which can spoil food. Although not as potent as vitamin C, it is effective in preserving freshness and extending the shelf life of food products.
