Sodium Erythorbate is important antioxidant in food industry, which can keep the color, natural flavor of foods and lengthen its storage without any toxic and side effects. They are used in meat processing, fruits, vegetable, tin and jam etc. Also they are used in drinks, such as beer, grape wine, soft drink, fruit tea and fruit juice etc. In solid state it is stable in air, Its water solution is easily mutated when it meets with air, trace metal heat and light.Sodium Erythorbate is an antioxidant that is the sodium salt of Erythorbic acid. In the dry crystal state it is nonreactive, but in water solution it readily reacts with atmospheric oxygen and other oxidizing agents, a property that makes it valuable as an antioxidant. During preparation, a minimal amount of air should be incorporated and it should be stored at a cool temperature. it has a solubility of 15 g in 100 ml of water at 25°c. on a comparative basis, 1.09 parts of sodium erythorbate are equivalent to 1 part of sodium ascorbate; 1.23 parts of sodium erythorbate are equivalent to 1 part erythorbic acid. it functions to control oxidative color and flavor deterioration in a variety of foods. in meat curing, it controls and accelerates the nitrite curing reaction and maintains the color brightness. it is used in frankfurters, bologna, and cured meats and is occasionally used in beverages, baked goods, and potato salad. it is also termed sodium isoascorbate.
