Erythorbic Acid (C₆H₈O₆) is a potent antioxidant used primarily in the food and beverage industry to preserve flavor, color, and nutritional value. It is an isomer of ascorbic acid (vitamin C) and shares similar properties, making it effective in preventing oxidative degradation of food products. Erythorbic Acid is commonly added to cured meats, beverages, and canned fruits and vegetables to enhance shelf life and maintain freshness. Its safety and efficiency in inhibiting oxidation make it a valuable additive in various food preservation applications.
