Sodium Erythorbate

Sodium erythorbate is an antioxidant which can be used in various food systems: e.g. meat, fish, beverages, fruit and vegetables, etc. Chemically, it is the sodium salt of erythorbic acid which is recognized as GRAS by the US Food and Drug Administration. It is an epimer (structural mirror image) of sodium ascorbate and is identical in antioxidant effect.

Eribate� brand sodium erythorbate is produced by fermentation of corn sugar to meet the specifications outlined in the Food Chemicals Codex (F.C.C.). Eribate� is proven nontoxic in all applications.

Sodium erythorbate may be used to preserve freshness in fruit and vegetables. It does this by preventing discoloration and development of off-flavors.

Sodium erythorbate serves as an inhibitor of enzymatic browning by scavenging oxygen and by reducing quinones back to polyphenol compounds before they can undergo the reactions to produce brown pigments. Fruit and vegetables can be protected by spraying or dipping them in an aqueous solution of sodium erythorbate.

PMP�s Eribate� brand sodium erythorbate has been used to prevent the premature deterioration of food products for many years. The most common methods of incorporating the antioxidant in fish tissue are: dipping, glazing, injection and spraying.

In meat products Eribate is used for faster processing and better appearance and flavor.

The industrial utilization of sodium erythorbate is increasing because of its recognized safety and environmental friendliness. Sodium erythorbate is selected as an additive for boiler water based on four key properties:

  • non toxic
  • oxygen scavenger
  • reducing agent
  • passivation agent

Certain ferric complexes can enhance corrosion when in contact with ferrometal surfaces in aqueous solution. If the ferric ion concentration exceeds the ferrous ion concentration, there is a tendency to cause corrosion. Therefore, it is beneficial to include in the water treatment formulation a chemical which can serve as a ferric ion reducing agent. Sodium erythorbate can prevent the formation and precipitation of ferric compounds by reducing the ferric ion to the ferrous state, thus inhibiting corrosion.
