What is Disodium Inosinate (IMP)?
Disodium inosinate (E631, IMP) is a widely used flavor enhancer that contributes to the umami taste in food products. It plays a crucial role in the food industry, often used in combination with other flavor enhancers like disodium guanylate and MSG. Disodium inosinate is the disodium salt of inosinic acid, a nucleotide that occurs naturally in various foods, particularly in meat and fish. I+G, a mixture of IMP and GMP (1:1), is more widely used in the food industry due to its lower cost and superior flavor-enhancing capabilities. According to the U.S. Food and Drug Administration (FDA), disodium inosinate is approved to be used in food.
Regulatory Status and Safety Considerations
Disodium inosinate has been evaluated by relevant regulatory authorities like JECFA, EFSA, EUR-Lex, ECHACHEM, FEMA, and WHO. In the EU, disodium inosinate is authorised as a food additive under the designation E631 within the ribonucleotide group E626–E635, governed by Regulation (EC) No 1333/2008. In the United States, disodium inosinate is regulated as a direct food additive under 21 CFR 172.535, which addresses its use as a flavouring adjuvant. It additionally carries FEMA GRAS status under reference number 3669. The Joint FAO/WHO Expert Committee on Food Additives has established a group acceptable daily intake of “not specified” for inosinic acid and its sodium, potassium, and calcium salts.
CAS No.: 4691-65-0
According to the American Chemical Society, the CAS number of disodium inosinate is 4691-65-0.
Chemical Formula: C10H11N4Na2O8P
