Caramel color is one of the most widely used food additives in the world, appearing in everything from cola and soy sauce to baked goods and beer. It is also one of the most frequently questioned ingredients on celiac disease forums. The concern is not unfounded: caramel color can legally be manufactured from malt syrup and wheat-based glucose syrups, both of which originate from gluten-containing grains.
Yet the expert consensus, backed by the International Technical Caramel Association and multiple registered dietitians specializing in celiac disease, is that caramel color is safe for a gluten free diet. The explanation lies in what happens to gluten proteins during the intense heating process that creates this additive.
Is Caramel Color Gluten Free
Yes, caramel color is considered gluten free. According to the International Technical Caramel Association (ITCA), caramel color produced from corn or cane-based materials is unlikely to contain gluten due to the absence of gliadin in those carbohydrates.
In North America, manufacturers typically use corn or sucrose as starting materials, with corn starch hydrolysate being the most common ingredient. Products from the North American caramel color industry are free of gluten.
Even caramel color derived from wheat is considered safe. The highly refined processing of glucose syrup results in the removal of the gluten protein gliadin.
Shelley Case, a registered dietitian on the Medical Advisory Boards of the Celiac Disease Foundation, the Gluten Intolerance Group, and the Canadian Celiac Association, has stated that the processing of caramel color results in a product that does not contain detectable gluten. The European Union permanently exempted wheat-based glucose syrups and their derivative products, including caramel color, from allergen labeling requirements in Directive 1169/2011/EC.
What Caramel Color Is Actually Made From
Caramel color is produced by heating food-grade carbohydrates to high temperatures. According to the FDA’s Code of Federal Regulations, acceptable starting materials include dextrose, invert sugar, lactose, malt syrup, molasses, starch hydrolysates (such as glucose syrup) and fractions thereof, and sucrose.
Tricia Thompson, MS, RD, of Gluten-Free Dietitian, explains that in North America, wheat is typically not used as a starting ingredient. Corn is the standard in the United States.
DD Williamson, one of the largest caramel color manufacturers globally, uses syrup derived from wheat, corn, or beet in its UK plants. However, in their North and South American facilities, neither wheat nor gluten is used as a starting material.
This geographic distinction matters for international food manufacturers sourcing caramel color from different regions. Products manufactured in Europe or Asia may have different source materials than those produced in North America.
Regional Labeling Rules That Affect Celiac Consumers
Labeling requirements for caramel color vary significantly around the world. In the United States, the Food Allergen Labeling and Consumer Protection Act (FALCPA) requires that wheat be declared on labels if it is used as an ingredient. If caramel coloring appears on a U.S. product label without a wheat allergen declaration, it should be safe for people with celiac disease or gluten sensitivity.
In the European Union, wheat-based glucose syrups and their products are exempted from allergen labeling, based on the EU starch industry’s “Code of Good Practice” committing to a maximum gluten level of 20 ppm for wheat starch hydrolysates. Australia takes the strictest approach, requiring that products labeled “gluten free” contain less than 3 ppm gluten, verified through independent testing. For gluten free in the U.S. and EU, the threshold is less than 20 ppm.
Caramel Color vs. Caramel Candy: An Important Distinction
The National Celiac Association warns consumers not to confuse caramel color, which is a food coloring additive, with caramel candy, which may contain gluten. Caramel candies and sauces can include wheat flour, barley malt, cookie pieces, or other gluten-containing ingredients. The word “caramel” on a label requires careful reading to determine whether it refers to the color additive or a flavored confection.
When evaluating a product label, check whether “caramel color” appears in the ingredients list as an additive or whether “caramel” is part of the product’s flavor profile. Caramel coloring as a listed ingredient is considered safe regardless of the starting material. Caramel-flavored products require full ingredient review and allergen statement verification before consumption by celiac patients.
