Disodium inosinate (E631) is the disodium salt of inosinic acid (IMP), a nucleotide naturally found in meat and fish. It is used as a flavor enhancer that acts synergistically with MSG — small amounts of IMP dramatically amplify the umami-enhancing effect of glutamates (the 'nucleotide-glutamate synergy' effect). It is often used alongside disodium guanylate (E627) and MSG.
Boosts umami flavor synergistically with glutamates, allowing manufacturers to use less MSG while achieving equivalent flavor enhancement in snack foods and seasonings.
Considered safe at food use levels by FDA and EFSA. Disodium inosinate is a purine derivative; individuals with gout or hyperuricemia are advised to limit purine-rich foods, and disodium inosinate may contribute to purine load. It may be derived from animal sources (meat or fish), making it unsuitable for vegans and vegetarians. It often appears alongside MSG on ingredient lists as part of a flavor enhancement system.
