Is E631 halal? The verdict
E631 is mashbooh (doubtful). The leading producers make it by fermentation, but it can also be extracted from meat or fish, and labels rarely state the source. 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.
