Sodium erythorbate Chemical Properties,Usage,Production

Chemical Properties

Sodium erythorbate is a white to yellow-white crystalline powder or granules that are slightly salty and almost odorless. It is stable in the dry state but can deteriorate when exposed to air, trace metals, heat and light in solution. The compound has a melting point above 200℃ (decomposition) and is soluble in water (17g/100m1) but almost insoluble in ethanol. The pH of a 2% aqueous solution ranges from 5.5 to 8.0.

Uses

Sodium Erythorbate is an antioxidant that is the sodium salt of erythorbic acid. in the dry crystal state it is nonreactive, but in water solution it readily reacts with atmospheric oxygen and other oxidizing agents, a property that makes it valuable as an antioxidant. during preparation, a minimal amount of air should be incorporated and it should be stored at a cool temperature. it has a solubility of 15 g in 100 ml of water at 25°c. on a comparative basis, 1.09 parts of sodium erythorbate are equivalent to 1 part of sodium ascorbate; 1.23 parts of sodium erythorbate are equivalent to 1 part erythorbic acid. it functions to control oxidative color and flavor deterioration in a variety of foods. in meat curing, it controls and accelerates the nitrite curing reaction and maintains the color brightness. it is used in frankfurters, bologna, and cured meats and is occasionally used in beverages, baked goods, and potato salad. it is also termed sodium isoascorbate.

Preparation

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
