[Synonyms]
Disodium 5'-inosinate, Sodium 5'-inosinate, Disodium inosine 5'-monophosphate, Inosine 5'-(disodium phosphate), Sodium inosinate
[Intro]
Sodium Inosinate 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.

[Usage]
Sodium Inosinate is used as a flavor enhancer, in synergy with monosodium glutamate (MSG) to provide the umami taste. It is often added to foods in conjunction with disodium guanylate; the combination is known as disodium 5'-ribonucleotides.
As a relatively expensive product, disodium inosinate is usually not used independently of glutamic acid; if disodium inosinate is present in a list of ingredients, but MSG does not appear to be, it is possible that glutamic acid is provided as part of another ingredient or is naturally occurring in another ingredient like tomatoes, Parmesan cheese or yeast extract
