Why this verdict

E635 is disodium 5-ribonucleotides (I+G), a flavour enhancer used in instant noodles, chips, seasonings, soup stocks, and savoury snacks. It is a mixture of disodium guanylate (E627) and disodium inosinate (E631). SANHA classifies E635 as Mushbooh because the inosinate component (E631) can be from animal sources, including non-halal meat. MUIS marks E635 as syubhah, noting it is a mixture of disodium guanylate (E627) and disodium inosinate (E631). Because the source is not disclosed on the label, E635 is doubtful by default.

Food-safety note
Permitted as a flavour enhancer in Australia and New Zealand under the Food Standards Code (Schedule 15). A blend of E627 and E631 used with MSG to boost savoury flavour; regarded as safe at the levels used in food. As nucleotides these add to dietary purines, which people managing gout may wish to note. (Source: FSANZ; Food Standards Code Schedule 15.)
