Physical and Chemical Properties: Erythorbic acid is a stereoisomer of vitamin C, thus sharing similar chemical properties. It appears as white to light yellow crystals or crystalline powder, odorless, with a sour taste. In its dry state, it is relatively stable in air, but deteriorates rapidly when exposed to the atmosphere in solution. It has almost no physiological activity of ascorbic acid, but its antioxidant properties are superior to those of ascorbic acid. However, it has poor heat resistance and strong reducing properties. Heavy metal ions can promote its decomposition. Erythorbic acid is highly soluble in water (40g/100ml), soluble in ethanol (5g/100ml), slightly soluble in glycerol, and insoluble in ether and benzene.

Product Uses: The antioxidant capacity of erythorbic acid far exceeds that of vitamin C. It does not enhance vitamin C activity but does not hinder the absorption and utilization of ascorbic acid by the human body. When ingested, erythorbic acid can be converted into vitamin C in the body. Its physiological effect in terms of anti-scurvy is only 1/20 that of ascorbic acid, but its effects in lowering blood pressure, diuresis, liver glycogen formation, pigment excretion, and detoxification are roughly the same as those of ascorbic acid. Erythorbic acid is mainly used in the food industry and is widely applied in meat products, fish products, beer, fruit juices, juice crystals, canned fruits and vegetables, pastries, dairy products, jams, wine, pickles, oils and fats, etc.
