Is E631 halal? The verdict

E631 is mashbooh (doubtful). Often derived from fish or meat by-products; verify source. 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.
