What it is and where it comes from
Caramel colours are brown colours made by heating sugars such as glucose or sucrose, sometimes with acids, alkalis, ammonia or sulphites to give different shades (E150a to E150d). There is no animal or alcohol source.
Where you find it
Cola and other soft drinks, gravy, soy sauce, brown bread, sauces, sweets and biscuits.
What to look for on the label
Nothing to check for halal. Whether the drink or food around it is halal is a separate question.
This is a guide, not a fatwa. Recipes change, so check the label, look for halal certification, and ask your local imam where scholars differ.
