Disodium inosinate (E631[2]) is the disodium salt of inosinic acid with the chemical formula C10H11N4Na2O8P. It is used as a food additive and often found in instant noodles, potato chips, and a variety of other snacks.

Commercial disodium inosinate may either be obtained from bacterial fermentation of sugars or prepared from animal products. The Vegetarian Society reports that production from meat or fish is more widespread,[3] but the Vegetarian Resource Group reports that all three "leading manufacturers" claim to use fermentation.[4]
