<<Disclaimer: Verify this information before applying it to your situation.>> In a telephone conversation 11/14, I called Sethness Products Company (888/772-1880) which has specialized in caramel COLOR since 1880. The technician assured me that only two companies supply all (100%) the caramel color in the US and much abroad, and all are gluten free. They supply both liquid and powdered versions. However, many companies manufacture caramel FLAVORING. That is an entirely different process and could contain gluten and needs individual investigation.
