Food Additive Antioxidant Sodium Erythorbate Food Grade 6381-77-7

In meat processing, it is frequently utilized as a color-fixing agent and preservative; it effectively preserves the vibrant color of the meat, inhibits the growth of bacteria—such as *Clostridium botulinum*—and enhances the flavor of meat products.

In the field of fruit and vegetable processing, it is incorporated into products such as fruit juices, jams, and canned goods to prevent enzymatic browning and to maintain their natural color and texture.

In the beverage industry, it serves to prevent the oxidation of Vitamin C, thereby ensuring the flavor stability of the beverages.

In the brewing of beer and wine, the addition of sodium isoascorbate helps eliminate stale off-flavors and enhances flavor stability. Furthermore, it is used in noodle-based products—such as instant noodles and bread—to improve product quality and extend shelf life.

In the animal feed industry, sodium isoascorbate acts as both an antioxidant and an immune booster, and is added to feed for pigs, poultry, fish, and pets. It promotes animal growth, improves feed conversion efficiency, and enhances the animals’ immunity and resilience to stress.

In the agricultural sector, sodium isoascorbate has been developed as a biostimulant, typically applied via foliar spraying. It promotes cell division and elongation in crops and boosts photosynthetic efficiency, thereby increasing crop yields; concurrently, it enhances the crops’ resistance to environmental stressors (such as drought and cold) and diseases, while also improving fruit quality.

In the daily chemical industry, sodium isoascorbate is incorporated into skincare products and cosmetics, leveraging its antioxidant properties. It scavenges free radicals within skin cells and protects the skin from oxidative damage, thereby helping to delay skin aging and improve overall skin texture.

In the pharmaceutical field, sodium isoascorbate primarily serves as a pharmaceutical excipient; it is utilized in formulations such as injectable solutions and eye drops, acting as a stabilizer to prevent the oxidative degradation of active pharmaceutical ingredients (such as Vitamin C).
