Sodium erythorbate is widely used as an antioxidant in the food industry, particularly in processed meats like sausages, hot dogs, and cured meats. It helps preserve color, flavor, and freshness by preventing oxidation and spoilage. In beverages, it acts as a stabilizer to maintain quality and extend shelf life. Additionally, it is used in the pharmaceutical industry to enhance the stability of certain medications. Its ability to inhibit the formation of nitrosamines in cured meats makes it a valuable additive for food safety.
