Infobox disclaimer and references

Disodium guanylate (E627), also known as sodium 5'-guanylate and disodium 5'-guanylate, is the disodium salt of the flavor enhancer guanosine monophosphate (GMP). Disodium guanylate is a food additive and is usually used in synergy with glutamic acid (monosodium glutamate, MSG).

As it is a fairly expensive additive, it is not used independently of glutamic acid; if disodium guanylate 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 such as a processed soy protein complex. It is often added to foods in conjunction with disodium inosinate; the combination is known as disodium 5'-ribonucleotides.

Disodium guanylate is produced from dried fish or dried seaweed and is often added to instant noodles, potato chips and snacks, savoury rice, tinned vegetables, cured meats, packet soup.
