Calcium Formate (E238)

Type of additive
(Glossary)
Acidity Regulators, Preservatives
E NumberE238
Chemical FormulaCa(HCO2)2
Also Known AsFormic acid calcium salt
Calcoform

Purpose and Function

Calcium Formate (E238) is used in the food industry as a preservative and acidity regulator. It helps to prevent the growth of harmful microorganisms and regulate the pH in certain products, thereby extending shelf life. However, its use in food is relatively limited due to safety concerns. Potential applications include:

  • Animal feed: More commonly used in animal feed to inhibit microbial growth and improve feed stability.
  • Industrial applications: Primarily used in non-food applications, such as in concrete additives or as a de-icing agent.

Although Calcium Formate (E238) can function as a preservative, it is not commonly used for food products intended for direct human consumption.


Potential Risks and Side Effects

alcium Formate (E238) has some risks and safety considerations that limit its use as a food additive:

  • Toxicity concerns: E238 can be toxic if consumed in large amounts. It is typically reserved for industrial and animal feed applications rather than food for human consumption.
  • Irritation: May cause skin, eye, or respiratory irritation if handled improperly.
  • Regulatory restrictions: The use of Calcium Formate (E238) as a food additive is banned or restricted in many regions, including the European Union, due to potential safety concerns. In regions where it is allowed, its use is limited, with specific regulations to ensure consumer safety.

These risks mean that Calcium Formate (E238) is not commonly used in food preservation and is subject to regulatory limitations.
