E585 — Ferrous Lactate

Ferrous lactate, designated as E585, is the iron (II) salt of lactic acid. It appears as a greenish-white powder or crystalline mass with a characteristic odor. In the food industry, ferrous lactate serves primarily as an acidity regulator, color retention agent, and iron fortifier. 

Danger Level: 0 — Safe

Purpose in Products

In the food industry, ferrous lactate serves several functions:

  • Acidity Regulator: It adjusts the pH levels in food products, enhancing flavor and preservation.
  • Color Retention Agent: Ferrous lactate helps maintain the color of food items, such as olives, by preventing discoloration. 
  • Iron Fortifier: It is used to fortify foods with iron, addressing iron deficiency anemia.

Health Considerations

Ferrous lactate is considered safe for consumption when used within established limits. The European Food Safety Authority (EFSA) has evaluated its safety and concluded that it poses no health concerns at the current authorized use and use levels. 

Impact on Children

Ferrous lactate is safe for children when present in food products at the levels typically used in food processing.

Impact on Taste

Ferrous lactate is tasteless and odorless, making it an ideal ingredient for various food products without altering their flavor profiles.

Compatibility with Other Additives

Ferrous lactate is compatible with various other food additives, including acids and salts. Its iron content makes it suitable for use in products requiring iron fortification.

Natural Occurrence

Lactic acid, the precursor to ferrous lactate, is naturally present in fermented foods and dairy products.

Alternatives and Substitutes

For those seeking alternatives to E585, options include:

  • Ferrous Sulfate (E533): Another iron supplement used in food fortification.
  • Ferrous Gluconate (E579): An alternative iron supplement with similar applications.

Regulation

Ferrous lactate is approved for use as a food additive in many countries, including the European Union, where it is designated as E585. Regulatory bodies such as the European Food Safety Authority (EFSA) have evaluated its safety and concluded that it poses no health concerns when used within established limits. 

Conclusion

Ferrous lactate (E585) is a versatile and safe food additive used primarily as an acidity regulator, color retention agent, and iron fortifier. Its unique properties make it valuable in various food products, enhancing both nutritional value and visual appeal. While generally safe, individuals with specific sensitivities should exercise caution.
