Caramel Color

Caramel coloring refers to any of the four classes of caramel food coloring, two of which are associated with cancer. The manufacturing process of Class III and Class IV caramel color produces carcinogenic byproducts that can remain in the final product. Although you’d have to eat an excess of caramel coloring to consume enough of the byproduct to cause cancer, those trying to avoid synthetic ingredients should steer clear of caramel coloring.
