Disodium Inosinate An expensive flavor enhancer usually used with the cheaper Monosodium Glutamate (MSG) alternative. Disodium 5â€™-inosinate, or E631, comes from the nucleotide Inosine monophosphate (IMP) commonly found in mushrooms and meats. Nucleotides are information-carrying molecules (seen in DNA) and help with the bodyâ€™s metabolic processes. It is produced by microbial fermentation in vegetables and put in tapioca starch to make it a powder form. It is approved by the Food and Drug Administration but like MSG, is associated with certain allergic reactions after consumption. See Monosodium Glutamate. "Disodium Inosinate Side Effects."
