Uses and synthesis of Sodium D-isoascorbate Powder

Sodium D-isoascorbate CAS 7378-23-6 is an optical isomer of vitamin C (ascorbic acid, VC), which is chemically similar to VC and has a strong reducing effect. In terms of physiological effects, although the anti-scorbutic effect of Sodium D-isoascorbate CAS 7378-23-6 is only 1/20th of that of VC, it possesses almost the same antihypertensive, diuretic, detoxifying, and hepatic gluconeogenesis and pigment excretion effects as VC.

Sodium D-isoascorbate Powder has a wide range of uses, which are summarized as follows: as food antioxidant and anticorrosive color enhancer for meat products; as auxiliary material for drugs, medicines or hygiene products; as stabilizer for chemical raw materials; as an important component of solvent for de-oxygenation, anticorrosion and descaling; as a chemical additive in acidification treatment of oil field strata; as electrolysis, electroplating in the It is also used as electrolyte in electrolysis and electroplating, in the production of metal micropowder and the recovery of precious metals, in the production of some polymers, and as raw material for the production of image recording materials. In addition, Sodium D-isoascorbate Powder is also used in textile, building materials, military industry and daily chemical industry.

Sodium D-isoascorbate Raw Materials has a wide range of uses, but its most important use is still in food processing. Sodium D-isoascorbate Raw Materials is a promising metabolizable antioxidant, whose anticorrosive and antioxidant effect greatly exceeds that of vitamin C, but the price is less than 1/2. Sodium D-isoascorbate Raw Materials has color-enhancing effects on meat and seafood, and also inhibits the generation of the carcinogenic substance nitrite in food, and has the effects of lowering blood pressure, diuretic and detoxification in medicine. In medicine, it can lower blood pressure, diuretic and detoxification. At present, this product has been widely used in meat, fruits, beverages and other foods, but also can be used in wool spinning, electroplating, feed processing, industrial water treatment and petrochemical industries.

Sodium D-isoascorbate Raw Materials, also known as Sodium D-isoascorbate, is a new type of biological food antioxidant, anticorrosive and freshness coloring agent. It can prevent the formation of carcinogen - nitrosamine in pickled products, and eliminate the undesirable phenomena such as discoloration, odor and turbidity of food and beverage. Widely used in meat, fish, vegetables, fruits, wine, beverages and canned food, Sodium D-isoascorbate Raw Materials is mainly made from rice as the main raw material, which is produced by microbial fermentation.

Applications / Functions of Sodium D-isoascorbate Powder

• 1）Sodium D-isoascorbate Raw Materials in medicine: isoascorbic acid has the effect of lowering blood pressure, diuretic, hepatic gluconeogenesis, pigment excretion, detoxification, etc. It can be used in liver and gallbladder imaging or bone imaging; it can be used in the treatment of renal stones; it can be used as auxiliary materials for drugs, medicines or hygiene products.
• (2) Sodium D-isoascorbate Powder in chemical industry: isoascorbic acid can stabilize the chemical reaction and moderate the reaction rate, can be used as a stabilizer for chemical raw materials, deoxygenation, anticorrosive and descaling solvent important components.

Sodium D-isoascorbate CAS 7378-23-6 is used as food antioxidant, anticorrosive color enhancer.

Sodium D-isoascorbate CAS 7378-23-6 is an important antioxidant and preservative in the food industry, which can maintain the color and luster of the food, natural flavor, prolong the shelf life, and without any toxic side effects, it is mainly used in the food industry for meat products, fruits, vegetables, canned goods, jam, beer, soft drinks, fruit tea, juice, wine, etc. It is also used as an antioxidant, anticorrosive and descaling solvent, which can be used as an antioxidant, anticorrosive and descaling solvent.

• 1. in meat products: as a coloring additives, to maintain the color, to prevent the formation of nitrosamines (such as nitrites), to improve flavor
• In meat products: as a coloring aid to maintain color, prevent the formation of nitrosamines (such as nitrite) and improve flavor. Pickled vegetables: to maintain the color and improve the flavor.
• 2. Frozen fish and shrimp: to maintain color and luster, to prevent oxidation of the surface of the fish to produce a rotten smell.
• 3. beer and wine: added after fermentation to prevent odor and turbidity, maintain color and flavor, and prevent secondary fermentation.
• 4. Juice and sauces: add when bottling to maintain natural VC, prevent color fading, and keep the original flavor.
• 5. Fruit storage: Spray or use with citric acid to maintain color and flavor and prolong storage period.
• 6. Canned goods: add to soup before canning to maintain color and flavor.
• 7. Used in bread, it can keep the color, natural flavor and extend the shelf life of bread without any toxic side effects.

Sodium D-isoascorbate Powder properties and stability

Sodium D-isoascorbate CAS 7378-23-6 Appearance is white or yellowish crystalline granular powder, melting point is 218 ℃, odorless, slightly salty, soluble in water, the pH value of its aqueous solution is 5~6, almost insoluble in ethanol; dry state is relatively stable, but when exist in the solution state, it is susceptible to oxidation by the action of air, metal ions, heat or light. Sodium D-isoascorbate Powder is produced from edible starch through bio-fermentation, refining, synthesis, concentration and crystallization.

Sodium D-isoascorbate Raw Materials Molecular Formula: C6H7NaO6-H2O. molecular weight: 216.12 melting point 200℃. white or slightly yellow crystalline. White or slightly yellow crystalline particles or powder, odorless, slightly salty, soluble in water (about 7mL water can dissolve 1g).

Sodium D-isoascorbate Raw Materials dry state in the air is stable, aqueous solution is easy to deteriorate when exposed to air, trace metals, heat and light.

Production methodprocess of Sodium D-isoascorbate Powder

Sodium D-isoascorbate Powder is made from glucose, inoculated with Pseudomonas fluorescens, and fermented by aeration to obtain calcium α-ketogluconate, after acidification and calcium removal, methanol and a small amount of sulfuric acid are added to carry out esterification to obtain solid methyl gluconate. The ester was dissolved in methanol, and metal sodium was added, and the mixture was heated to produce oral isoascorbic acid sodium salt precipitate, which was separated and then refined to obtain the product.
