| Introduction | sodium vitamin c is a white or extremely yellowish crystalline or crystalline powder substance, which is stable in a dry state and easy to oxidize and decompose under wet conditions. The color of the light becomes darker, with a specific rotation of 104.4 ℃. |
| Pharmacological action | Vitamin C sodium participates in the metabolism and redox process of sugar in the body; participates in the formation of intercellular substance and blood coagulation process, reduces capillary fragility; participates in detoxification Function, increase resistance to infection; promote folic acid to form tetrahydrofolic acid, increase the absorption of iron in the intestine. |
| application | sodium vitamin c is the main intermediate product in the production of vitamin c. at the same time, sodium vitamin c is also an important food additive. it is used as an antioxidant to prevent food and beverage from changing color and taste. it is widely used for preservation and fixation of ham, sausage and cake and mildew prevention of moon cakes. it is added to cosmetics for anti-wrinkle, anti-aging and whitening, it has the dual functions of supplementing VC and enhancing calcium absorption, and has stable performance. |
| indications | vitamin c sodium is suitable for (1) prevention and treatment of scurvy. (2) Idiopathic methemoglobinemia. (3) Various acute and chronic infectious diseases and purpura and other adjuvant treatment. |
| content analysis | about 0.400g of the sample dried in advance in a vacuum dryer (sulfuric acid) for 24 hours is dissolved in a mixture of 100ml of carbon dioxide-free water and 25ml of dilute sulfuric acid test solution (TS-241). Add several drops of starch test solution (TS-235) and immediately titrate with 0.1mol/L iodine solution to the end point. 0.1mol/L iodine solution is equivalent to 9.905mg of L-sodium ascorbate (C6H7O6Na) per mI. |
| toxicity | ADI does not make special regulations (FAO/WHO,2001). LD50 ≥ 5g/kg (rat, oral). GRAS(FDA,§ 182.3731,2000). |
| use limit | GB 14880-94: same as "0100l,L-ascorbic acid". GB 2760-2001: 0.1 g/kg of candy essence. FAO/WHO(1984): instant broth and soup, 1000 mg/kg; Luncheon meat, cooked minced meat, cooked pork shoulder meat, cooked foreign ham, canned baby food, baby and children's cereal products, 500 mg/kg; Frozen lobster, frozen perch uranium, cod, haddock, flatfish, hake and other fillets, 1 g/kg (based on ascorbic acid). |
| utilisation | as a food nutrition fortifier, the effect is the same as ascorbic acid, and the usage amount needs to be converted. In addition, it can be used as a color protector and antioxidant. The effect of this product is roughly the same as that of ascorbic acid. It is used as a vitamin C fortifier for various foods and can be used for refreshing beverages and dairy products. It is also used in foods such as ham and sausages to maintain blood color and freshness. Nutritional supplements, antioxidants; color fixative. The use of ascorbic acid is basically the same. |
| Méthode de production | add sodium bicarbonate to ascorbic acid solution, add isopropanol after standing for a while, and precipitate to obtain the product. Soluble ascorbic acid in an organic solvent, add sodium carbonate to heat it to react, precipitate after cooling, and filter to obtain the product. |
