E625 — Magnesium Diglutamate

amino acid. It appears as a white, odorless crystalline powder and is highly soluble in water. In the food industry, E625 is primarily used as a flavor enhancer, imparting the umami taste to various products. 

Danger Level: 0 — Safe

Purpose in Products

E625 serves several functions in food products:

  • Flavor Enhancer: It enhances the savory taste of foods, reducing the need for added salt. 
  • Umami Taste: Magnesium diglutamate imparts the umami taste, considered the fifth basic taste alongside sweet, sour, salty, and bitter.

Health Considerations

Magnesium diglutamate 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

Magnesium diglutamate is safe for children when present in food products at the levels typically used in food processing.

Impact on Taste

E625 enhances the savory flavor of foods without imparting a distinct taste of its own.

Compatibility with Other Additives

Magnesium diglutamate is compatible with various other food additives, including acids and salts.

Natural Occurrence

Glutamic acid, the precursor to magnesium diglutamate, is naturally present in foods such as tomatoes, cheese, and soy sauce.

Alternatives and Substitutes

For those seeking alternatives to E625, options include:

  • Monosodium Glutamate (E621): A sodium-based flavor enhancer.
  • Monopotassium Glutamate (E622): A potassium-based flavor enhancer.

Regulation

Magnesium diglutamate is approved for use as a food additive in many countries, including the European Union, where it is designated as E625. 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

Magnesium diglutamate (E625) is a safe and effective food additive used primarily as a flavor enhancer, imparting the umami taste to various products. Its unique properties make it valuable in food processing, enhancing flavor and reducing the need for added salt. While generally safe, individuals with specific sensitivities should exercise caution.
