E541 — Sodium Aluminium Phosphate

Sodium aluminium phosphate (E541) is an inorganic compound used in the food industry primarily as a leavening agent and emulsifier. It appears as a white, odorless powder and is synthesized by combining alumina, phosphoric acid, and sodium hydroxide. 

Danger Level: 0 — Safe

Purpose in Products

In the food industry, sodium aluminium phosphate serves several functions:

  • Leavening Agent: In its acidic form, it reacts with baking soda to release carbon dioxide, aiding in the rising of baked goods such as cakes, muffins, and biscuits. 
  • Emulsifier: In its alkaline form, it is used in processed cheese products to improve texture and stability.

Health Considerations

Sodium aluminium phosphate 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

Sodium aluminium phosphate is safe for children when present in food products at the levels typically used in food processing.

Impact on Taste

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

Compatibility with Other Additives

Sodium aluminium phosphate 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

Sodium aluminium phosphate is not naturally occurring in foods but is synthetically produced for use as a food additive.

Alternatives and Substitutes

For those seeking alternatives to E541, options include:

  • Monocalcium Phosphate (E341(i)): Another leavening agent used in baking powders.
  • Sodium Acid Pyrophosphate (E450(i)): Used as a leavening agent and emulsifier in various food products.

Regulation

Sodium aluminium phosphate is approved for use as a food additive in many countries, including the European Union, where it is designated as E541. 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

Sodium aluminium phosphate (E541) is a versatile and safe food additive used primarily as a leavening agent and emulsifier. Its unique properties make it valuable in various food products, enhancing texture and stability. While generally safe, individuals with specific sensitivities should exercise caution.
