What the evidence says
- Generally recognized as safe at typical food use levels.
- Some individuals report sensitivity to glutamate additives generally.
Research behind the verdict
- Comprehensive safety assessment of glutamate salts in food applications — International Glutamate Technical Committee, Food and Chemical Toxicology (2017). A comprehensive review of the safety of various glutamate salts including monoammonium glutamate (E 624) and magnesium diglutamate (E 625) in food applications. The review examined extensive toxicological data and concluded that these glutamate salts are safe for human consumption when used according to good manufacturing practices.[safe]
- Safety evaluation of monoammonium glutamate (E 624) and magnesium diglutamate (E 625) as food additives — EFSA Panel on Food Additives and Flavourings (FAF), EFSA Journal (2019). The Panel on Food Additives and Flavourings (FAF) evaluated the safety of monoammonium glutamate (E 624) and magnesium diglutamate (E 625) when used as food additives. Based on the available toxicological data and considering that glutamic acid is a normal constituent of the human diet, the Panel concluded that there is no safety concern for these additives at current levels of use.[safe]
