Infobox disclaimer and references

Disodium inosinate (E631), chemical formula C10H11N2Na2O8P, is the disodium salt of inosinic acid. It is a food additive often found in instant noodles, potato chips, and a variety of other snacks. It is used as a flavor enhancer, in synergy with monosodium glutamate (also known as MSG; the sodium salt of glutamic acid) to provide the umami taste.

Additional recommended knowledge

As it is a fairly expensive additive, it is 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 likely that glutamic acid is provided as part of another ingredient. It is often added to foods in conjunction with disodium guanylate; the combination is known as disodium 5'-ribonucleotides.
