E354 – Calcium Tartrate

E354 is the calcium salt of tartaric acid, a natural acid present in fruits, especially grapes. It functions primarily as an acidity regulator and preservative in various food products. Calcium Tartrate is generally recognized as safe for consumption within regulated limits, with no known harmful side effects. 

Danger Level: 1 (Safe with Minimal Risks)

Purpose in Products

Calcium Tartrate serves multiple functions in the food industry:

  • Acidity Regulation: Maintains desired pH levels in foods and beverages, ensuring product stability and taste consistency.
  • Preservation: Acts as a preservative by inhibiting microbial growth, thereby extending shelf life.

Common applications include:

  • Fish and Fruit Preserves: Used to regulate acidity and preserve products.
  • Seaweed Products: Maintains product quality and extends shelf life.
  • Pharmaceuticals: Utilized in certain medicinal formulations.

Health Considerations

Calcium Tartrate is metabolized in the body to tartaric acid. There are no known side effects associated with its consumption within regulated limits. The European Food Safety Authority (EFSA) has not defined a specific Acceptable Daily Intake (ADI) for Calcium Tartrate, indicating its safety at typical consumption levels. 

Impact on Children

Calcium Tartrate is safe for children when consumed within recommended dietary limits. However, quantity restrictions exist for its use in biscuits and rusks for infant weaning.

Impact on Taste

Calcium Tartrate is generally tasteless and does not significantly impact the flavor of food products. Its primary role is in acidity regulation and preservation.

Compatibility with Other Additives

Calcium Tartrate is compatible with various food additives and ingredients, making it versatile in food processing. It can be used alongside other acidity regulators and preservatives to achieve desired product qualities.

Natural Occurrence

Calcium Tartrate does not occur naturally in foods but is synthesized from tartaric acid, which is naturally present in many fruits, especially grapes. 

Alternatives and Substitutes

Alternatives to Calcium Tartrate include other acidity regulators and preservatives, such as:

  • Tartaric Acid (E334): A naturally occurring acid used as an acidity regulator and stabilizer.
  • Citric Acid (E330): A common acidity regulator and flavoring agent.

The choice of alternative depends on the specific application and desired properties of the food product.

Regulation

Calcium Tartrate (E354) is approved for use as a food additive in many countries, including those in the European Union. It is approved for all foods, with quantity restrictions existing only for its use in biscuits and rusks for infant weaning. 

Conclusion

E354 (Calcium Tartrate) is a versatile food additive employed as an acidity regulator and preservative in various products. When used within regulatory guidelines, it is generally safe for consumption, contributing to product quality and stability. There are no known harmful side effects associated with its consumption within regulated limits.
