E631 - Disodium inosinate
By the Daat team · Updated October 30, 2026
E631 is a flavour enhancer that is often made from meat or fish, though it can also be made by fermentation.
It is the constant partner of E627, and the two together even have their own code, E635. If you are vegan and find it in a "vegetable flavour" snack, only the manufacturer can say what the source is.
184 products in our catalog contain E631, or 1.1% of those with an ingredient list. Most of them are savoury snacks and meat products.

Is E631 vegan?
You cannot tell from the label. E631 can come from a plant or an animal source; only a vegan certification or the manufacturer can settle it.
