Sodium Formate (E237)

Type of additive
(Glossary)
Acidity Regulators, Preservatives
E NumberE237
Chemical FormulaHCOONa
Also Known AsSodium Methanoate

Purpose and Function

Sodium Formate (E237) is used as a preservative and acidity regulator in the food industry. It helps to inhibit the growth of harmful microorganisms, thus extending the shelf life of certain products. However, its use in food is relatively limited due to safety concerns. Potential applications include:

  • Preserved vegetables: Could be used in pickled products or brines to help prevent spoilage.
  • Animal feed: More commonly used in the preservation of animal feed to inhibit microbial growth.

Although Sodium Formate (E237) can serve as a preservative, it is not commonly found in food products for direct human consumption.


Potential Risks and Side Effects

Sodium Formate (E237) has some potential risks and safety concerns that have limited its use as a food additive:

  • Toxicity concerns: E237 can be harmful if consumed in large quantities. It is more commonly used in industrial applications, and its use in food is tightly regulated.
  • Irritation: May cause skin, eye, or respiratory irritation if exposed in significant amounts.
  • Regulatory restrictions: The use of Sodium Formate (E237) as a food additive is banned in many regions, including the European Union, due to safety concerns. Even in areas where it may be allowed, its use is limited, with strict guidelines to ensure consumer safety.

Because of these risks, Sodium Formate (E237) is not commonly used in food preservation and is subject to strict regulatory scrutiny.
