E471 – Mono- and Diglycerides of Fatty Acids

Danger Level: 0 (Safe)

E471, known as mono- and diglycerides of fatty acids, is a common food additive used primarily as an emulsifier and stabilizer. It is derived from glycerol and natural fatty acids, which can originate from both plant and animal sources. 

Purpose in Products

E471 serves several functions in food products:

  • Emulsifier: Facilitates the mixing of water and oil, preventing separation in products like margarine, ice cream, and baked goods. 
  • Stabilizer: Enhances texture and consistency in various processed foods, ensuring uniformity and quality. 
  • Anti-Staling Agent: In baking, it helps maintain softness and extends the shelf life of products like bread and cakes. 

Health Considerations

E471 is generally recognized as safe (GRAS) by food safety authorities, including the European Food Safety Authority (EFSA). In 2017, EFSA re-evaluated mono- and diglycerides of fatty acids and found no safety concerns for their use as food additives. 

However, it’s important to note that E471 may contain small amounts of trans fats, especially if derived from partially hydrogenated oils. Excessive intake of trans fats has been linked to health issues such as cardiovascular diseases. Therefore, moderation is advised. 

Impact on Children

E471 is considered safe for children when consumed as part of a balanced diet. As with all additives, it’s advisable to monitor intake to ensure it remains within recommended dietary guidelines.

Impact on Taste

At typical usage levels, E471 does not impart any noticeable taste to food products. Its primary role is to improve texture, stability, and shelf life without affecting flavor.

Compatibility with Other Additives

E471 is compatible with a wide range of food additives and ingredients. It often works synergistically with other emulsifiers and stabilizers to enhance product quality and consistency.

Natural Occurrence

Mono- and diglycerides are naturally present in various seed oils, though in low concentrations. Commercially, they are produced through the glycerolysis reaction between triglycerides (fats/oils) and glycerol. The raw materials for production may be either vegetable oils or animal fats. 

Alternatives and Substitutes

While E471 is widely used, alternatives include:

  • Lecithin (E322): A natural emulsifier derived from soybeans or sunflower seeds.
  • Sorbitan Esters (E491–E495): Synthetic emulsifiers used in various food applications.
  • Polyglycerol Esters (E475): Emulsifiers used in bakery and confectionery products.

Regulation

E471 is approved for use as a food additive in many countries, including those in the European Union, the United States, Canada, Australia, and New Zealand. Its use is regulated under good manufacturing practices to ensure safety. 

Conclusion

E471 (Mono- and Diglycerides of Fatty Acids) is a versatile and widely used food additive that enhances the quality and shelf life of various food products. When consumed in moderation as part of a balanced diet, it is considered safe for the general population.
