E472B — Lactic Acid Esters of Mono- and Diglycerides of Fatty Acids

E472b, known as lactic acid esters of mono- and diglycerides of fatty acids, is a food additive used primarily as an emulsifier. It is synthesized by esterifying glycerol with lactic acid and fatty acids, resulting in a compound that enhances the mixing of oil and water phases in food products. 

Danger Level: 0 — Safe

Purpose in Products

E472b serves several functions in food products:

  • Emulsifier: Facilitates the blending of oil and water components, ensuring uniform texture in products like salad dressings, mayonnaise, and sauces.
  • Stabilizer: Maintains the consistency and texture of emulsions, preventing separation and enhancing product stability.
  • Aeration Agent: Improves the aeration properties of high-fat recipes, producing a stable foam in whipped products by collecting together the fat globules. 

Health Considerations

E472b is considered safe for consumption. The European Food Safety Authority (EFSA) has evaluated its safety and concluded that there is no need for a numerical acceptable daily intake (ADI) for E472b, indicating no safety concern at the reported uses and use levels. 

Impact on Children

E472b is safe for children when consumed in typical dietary amounts.

Impact on Taste

E472b is tasteless and odorless, making it an ideal ingredient for various food products without altering their flavor profiles.

Compatibility with Other Additives

E472b is compatible with various other food additives, including sugars and other hydrocolloids. Its water-binding properties make it suitable for use in products requiring moisture retention.

Natural Occurrence

E472b is a synthetic compound and does not occur naturally.

Alternatives and Substitutes

For those seeking alternatives to E472b, options include:

  • Lecithin (E322): A natural emulsifier derived from soybeans or egg yolks.
  • Mono- and Diglycerides of Fatty Acids (E471): Commonly used emulsifiers in various food products.

Regulation

E472b is approved for use as a food additive in many countries, including the European Union, where it is designated as E472b. 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

Lactic acid esters of mono- and diglycerides of fatty acids (E472b) are versatile and safe food additives used primarily as emulsifiers, stabilizers, and aeration agents. Their unique properties make them valuable in various food products, enhancing texture and stability. While generally safe, individuals with specific sensitivities should exercise caution.
