6381-77-7 Usage


It is antioxidant and antiseptic.
Sodium Isoascorbate is a water-soluble antioxidant which is widely used in China and abroad. Its antioxidant property is significantly stronger than vitamin C. Its price is cheap as well. China provides that it can be used for all types of canned, jam and frozen fish with the maximum usage amount of 1.0g/kg; It can be used for meat with the maximum usage amount being 0.5g/kg (to ascorbic acid dollars); can be used for wine and fruit juice drinks with the largest usage amount being 0.15g/kg; can also be used for beer with the maximum usage amount being 0.04g/kg.
For food antioxidants, preservatives and coloring agent


ADI is not subject to any special provision (FAO/WHO, 2001).
LD50} 15.3 g/kg (mouse, orally).

Fire Hazard

Flash point data for Sodium erythorbate are not available; however, Sodium erythorbate is probably combustible.

Content analysis

0.400 g of the sample pre-dried in a vacuum desiccator (sulfuric acid) for 24 hours was dissolved in a mixed solution consisting of 100 ml of de-carbonated water and 25 ml of dilute sulfuric acid solution (TS-241). Add a few drops of starch solution (TS-235) and immediately titrate with 0.1mol/L iodine solution titration. Each mL of 0.1 mol/L iodine solution was equivalent to 10.807 mg of sodium erythorbate (C6H7O6Na? H2O).


It is produced through using D-glucose fermentation of Pseudomonas fluorescens Kl005 or Arthrobacter globiformis K1022 to produce 2-keto-D-gluconic acid (or calcium salt), followed by being esterified, transformed and refined. The composition of the fermentation medium is: glucose: 18; yeast extract 0.3; K2HPO4 • 3H2O: 0.05; KH2PO4: 0.05; MgSO4 • 7H2O: 0.025,;CaCO:34.5. The fermentation temperature is controlled at 30~35 ℃, the fermentation period is 30h, and the fermentation conversion ratio (%) is 79.9%. The fermentation broth is supplemented with sulfate and activated carbon for acidification and decoloring, followed by pressurized filtrate to obtain the clean liquid with a yield of 96.6%.
The purified fermentation broth was concentrated by decompression, and methanol and sulfuric acid were added for refluxed esterification of 5h, followed by frozen and centrifuged filtering to obtain methyl ester with a yield of 82.1%. The methyl ester was transformed with basic methanol solution under refluxing conditions, and the product was further frozen and crystallized to dryness to obtain the crude product of D-isoascorbic acid. The conversion yield was 87.3%, and it was dissolved in hot water and decolorized with activated carbon. The filtrate is pressurized filtrated and the supernatant liquid is frozen, crystallized, centrifugalized, washed and vacuum dried to obtain finished product.
The mother liquid is recovered and the yield is 88.0%.

General Description

Almost odorless fluffy, white to off-white crystalline powder. Used as an antioxidant and preservative.

Usage limit

GB 2760-2001 (g/kg): beer 0.04; wine, fruit and vegetable juice drinks, 0.15. Canned fruits and vegetables, canned meat, jam, frozen fish, 1.0 (all based on ascorbic acid).
FAO/WHO (1984): luncheon meat, boiled forelegs, cooked ham, cooked minced meat, 500mg/kg (single usage amount or combined amount with ascorbic acid, ascorbic acid and its salts in ascorbic acid).

Chemical properties

It appears as white to yellow-white crystalline powder or granules. It is almost odorless, slightly salty. In the dry state, it is quite stable in the air. However in solution, it will deteriorate in the presence of air, trace metals, heat and light. The melting point is above 200 ℃ (decomposition). It is soluble in water (17g/100m1) but almost insoluble in ethanol. The pH of the 2% aqueous solution was 5.5 to 8.0.

Reactivity Profile

Sodium erythorbate may be sensitive to prolonged exposure to light. Incompatible with strong oxidizing agents .

Air & Water Reactions

Water soluble.

Identification test

Solubility: it is easily soluble in water; extremely difficult to dissolve in ethanol. It can be measured according to the OT-42 method.
Take 2 ml of 2.0% sample solution; add 2 mL of water, 0.1 g sodium bicarbonate and 0.02 g of ferrous sulfate. Stand after shaking. At this time, it should exhibit dark purple color while addition of 5 mL of dilute sulfuric acid test solution (TS-241) will make the color disappeared.
The burning residue of the sample was dissolved by the water and subject to (TS-2) acidification, and if necessary, subject to filtration. Addition of uranyl zinc acetate test solution (TS-253) should produce yellow crystalline precipitate.
The aqueous solution of the sample allows the discoloration of the 2, 6-dichloroindophenol test solution (TS-84).
