Is E542 halal? The verdict
E542 is mashbooh (doubtful). Made from animal bones. It is permissible only if the bones come from halal-slaughtered animals, which the label never states, so treat it as doubtful. It is not an approved additive in the EU or UK. 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.
