E635, listed on labels as Disodium ribonucleotides, is a flavour enhancer that boosts the savoury (umami) taste. You'll most often find it in packaged and processed foods.

Is E635 halal? The verdict

E635 is mashbooh (doubtful). A blend of E627 and E631, so it inherits their source doubt. Doubtful unless certified. Manufacturers aren't required to print the source on the label, so unless the pack states a plant/vegetable source or carries a recognised halal certification (HMC, JAKIM, MUI, IFANCA), the safest choice is to avoid it.

Scan the ingredient list for E635 and its other names. If it's present and the source isn't stated, treat the product as doubtful. A barcode or photo scan with Halal Food AI flags E635 automatically and tells you whether the product declares a halal source.
