E1505 – Triethyl Citrate

Triethyl Citrate, designated as E1505, is a colorless, odorless liquid used in the food industry primarily as a foam stabilizer, emulsifier, and solvent. It is an ester of citric acid and ethanol, commonly utilized to stabilize foams, especially as a whipping aid for egg whites. 

Danger Level: 1 – Almost Safe

Purpose in Products

  • Foam Stabilizer: E1505 is used to stabilize foams, particularly in egg white preparations, ensuring consistent texture and volume in products like meringues and soufflés
  • Emulsifier: It helps blend ingredients that typically don’t mix well, such as oil and water, maintaining a uniform texture in products like certain beverages and confectioneries.
  • Solvent: E1505 acts as a solvent for flavorings and colorings, ensuring their even distribution throughout the product.

Health Considerations

Triethyl Citrate is generally considered safe for consumption in the amounts used as a food additive. It is metabolized by the body into citric acid and ethanol, both of which are naturally occurring substances. However, excessive intake should be avoided to prevent potential digestive discomfort.

Impact on Children

There is no specific evidence suggesting that E1505 poses additional risks to children when consumed in typical food quantities. Nonetheless, moderation is advised to prevent any potential adverse effects.

Impact on Taste

E1505 is nearly tasteless and odorless, ensuring it does not alter the natural flavor of food products. Its primary function is to aid in the stabilization of foams and emulsions without impacting taste.

Compatibility with Other Additives

Triethyl Citrate is compatible with various other food additives, particularly flavorings and colorings, enhancing their solubility and stability within the product. 

Natural Occurrence

Triethyl Citrate is an ester of citric acid and ethanol. While citric acid is naturally found in citrus fruits, Triethyl Citrate itself does not occur naturally and is synthesized for industrial use.

Alternatives and Substitutes

  • Lecithin: A natural emulsifier derived from soybeans or egg yolks, used to stabilize foams and emulsions in various food products.
  • Mono- and Diglycerides: Commonly used emulsifiers that help blend ingredients and stabilize textures in food preparations.

Regulation

E1505 is approved for use as a food additive in many countries, including those in the European Union, where it is designated as E1505. Regulatory bodies have evaluated its safety and established acceptable daily intake levels to ensure consumer safety. 

Conclusion

Triethyl Citrate (E1505) is a versatile additive that enhances the stability and texture of various food products without impacting their flavor. Generally recognized as safe, it can be consumed as part of a balanced diet. However, as with all food additives, moderation is key to prevent potential digestive discomfort.
