Use as an antioxidant, can be used for fermented flour products, the maximum amount is 0.2 g/kg; it can also be used for beer, the maximum amount is 0.04 g/h. It can also be used as a food nutrition enhancer.
Use water-soluble antioxidant
Use as chemical reagent and chromatographic reagent
Use vitamin drugs, used to prevent and treat scurvy, and also used for various acute and chronic infectious diseases and purpura.
Uses Vitamin C participates in the complex metabolic process of the body, can promote growth and enhance resistance to diseases. China stipulates that it can be used to strengthen sandwich hard candy, and the usage amount is 2000~6000 mg/kg. In high-speed rail cereals and their preparation. The usage amount of products (50g of food is limited to each day) is 800~1000 mg/kg; The usage amount in fortified infant food is 300~500 mg/kg; The usage amount in fortified canned fruits is 200~400 mg/kg; The usage amount in fortified drinking liquid and milk beverage is 120~240 mg/kg; The usage amount in fortified fruit puree is 50~100 mg/kg. In addition, this product has strong reducibility and can be used as an antioxidant.
Uses Vitamin C participates in the complex metabolic process of the body, can promote growth and enhance resistance to diseases, can increase the egg production of poultry and improve the quality of eggshells. When animals lack vitamin C, they will have symptoms such as loss of appetite, growth arrest, lack of fur, and anemia. In addition, this product has strong reducibility and is a good antioxidant.
Use Synthetic medicinal vitamin C is exactly the same as natural vitamin C. The product can promote folic acid into tetrahydrofolate, which is beneficial to nucleic acid synthesis and promotes the production of red blood cells. It can also reduce ferric ions to ferric ions, which is easy to be absorbed by the human body and is also beneficial to cell formation. Vitamin C is involved in the production of collagen in the body. It can neutralize toxins and promote the production of antibodies, which can enhance the detoxification function of the body. In medicine, it is mainly used for the prevention or treatment of scurvy, as well as for dental caries, gingival abscesses, anemia, growth and development stagnation and other diseases caused by insufficient anti-blood acid.
use vitamin drugs. Participate in the process of oxidation-reduction in the body, reduce capillary fragility and increase body resistance. For vitamin C deficiency, fever, chronic wasting diseases, etc.
Use of reference reagents for the determination of arsenic, iron, phosphorus and iodine, chromatographic analysis reagents, antioxidants, masking agents, reducing agents
Production method Medicinal vitamin C is synthetic. There are many methods of synthesis. Generally, D-sorbitol is made from glucose, and then oxidized and fermented by black acetate (Acetobacter Suboxydans) to produce L-sorbose, which is condensed to form diacetone-L-sorbose, and then oxidized to produce diacetone -2-one-L-Gluconic acid, and then esterified into methyl 2-keto-L-gluconate, which reacts with sodium methoxide to form sodium ascorbate, and. If the product is given to the animal in an amount that exceeds the physiological requirement, it will be excreted from the urine. Even when taken orally in large quantities, subcutaneously or intravenously, it can be tolerated. No poisoning was found when mice were given 0.5-1.0 g/kg orally every day for 7 days or a large amount of mice were given to livestock.
Production methods Vitamin C is widely found in fresh vegetables and fruits, and chemical enzymatic methods are usually used in industrial production. Glucose is hydrogenated and reduced to D-sorbitol under the catalysis of nickel, and then oxidized and fermented with acetic acid enzyme bacteria at 30-34 ℃ and PH5.2-5.5 to generate L-sorbose. In the presence of fuming sulfuric acid and -8 ℃, L-is dissolved in acetone and condensed with it to generate diacetone sorbitose. Under the catalysis of nickel sulfate and 75-80 ℃, sodium hypochlorite is oxidized to generate di, finally, it is hydrolyzed under acidic conditions to produce 2-keto-L-gulonic acid, and then ascorbic acid is obtained.
