It is a stereoisomer of vitamin C, so it is similar to vitamin C in chemical properties. The appearance is white to light yellow or crystal powder, odorless and sour, with a melting point of 166-172 ° C. it decomposes and gradually turns black when exposed to light. In dry state, it is quite stable in the air, but it deteriorates rapidly when exposed to the atmosphere in the solution. It has almost no physiological activity of ascorbic acid. Its antioxidant performance is better than ascorbic acid, but it has poor heat resistance and strong reducibility. Heavy metal ions can promote its decomposition. It is easily soluble in water, with a solubility of 40g / 100ml at normal temperature, soluble in ethanol, 5g / 100mL, insoluble in glycerol and insoluble in benzene. The pH value of 1% aqueous solution is 2.8.
Erythorbic acid and its sodium salt are widely used and have been used as food antioxidants to prevent browning in fish, meat, vegetables, fruit juices, etc. It is a new type of food antioxidant, antiseptic and preservative, which can effectively reduce the oxidation of food, prevent the fading of its color, aroma and taste, and also inhibit the formation of carcinogenic ammonium nitrite in food. At present, the product has been widely used in meat, vegetables, fruits, alcohol, beverages, canned food, tea and other foods. In addition to being used for food antioxidants, color additives, and preservatives, it also has important applications in medicine and health, and daily chemicals. In medicine, erythorbic acid has the functions of lowering blood pressure, diuresis, hepatic glycogen production, pigment excretion, detoxification, etc. It can be used for hepatobiliary imaging or bone imaging and treatment of kidney stones; in chemical industry, erythorbic acid can stabilize chemical reactions and ease reactions It can be used as a stabilizer for chemical raw materials, as well as an electrolyte in electrolysis and electroplating.
