It is often added to foods in conjunction with disodium inosinate; the combination is known as disodium 5'-ribonucleotides.; 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 commonly used in conjunction with glutamic acid (monosodium glutamate, MSG).
