Disodium guanylate, also known assodium 5'-guanylate anddisodium 5'-guanylate, is a naturalsodiumsalt of theflavor enhancing nucleotideguanosine monophosphate (GMP). Disodium guanylate is afood additive with theE number E627.[2] It is commonly used in conjunction withglutamic acid.
As it is a fairly expensive additive, it is usually not used independently ofglutamic acid; if disodium guanylate is present in a list of ingredients butMSG does not appear to be, it is likely that glutamic acid is provided as part of another ingredient such as a processedsoy proteincomplex. It is often added to foods in conjunction withdisodium inosinate; the combination is known asdisodium 5'-ribonucleotides.
Disodium guanylate is produced by fermentation.[3][4] It is often added toinstant noodles,potato chips and othersnacks, savoryrice, tinnedvegetables, curedmeats, and packagedsoup.
