What is Disodium Inosinate?
E631 is the E-number for disodium inosinate, one of the flavour enhancers group of food additives (E600–E699). Additives in this group boost the existing savoury flavour of foods. Often derived from meat or fish — which may include pork — though it can be made by fermentation. E631 can be produced by fermentation (vegan) or extracted from meat and fish — including pork in some cases — and the label never says which. It is one of the most-asked-about additives among vegetarian and Muslim consumers for exactly this reason. Like every E-number, E631 has been evaluated and authorised for use in food in the European Union — the 'E' literally stands for Europe, and a number is only granted after a safety assessment. That authorisation doesn't mean every additive suits every diet or that all concerns are settled, which is why we break down the safety, vegan, vegetarian and halal status of E631 in detail below.
