What to know

Formed by heating sugars to produce a range of brown colors and caramel flavors; the most widely used food colorant globally (E150a–E150d). Class IV caramel (ammonia-sulfite process, E150d) contains 4-methylimidazole (4-MEI), listed as a possible carcinogen under California's Prop 65; other classes (I and III) are considered safer. As a flavor, caramel adds a distinctly sweet, roasted, and slightly bitter note.
