Red Coloring

Red coloring refers to any substance added to food to impart a red hue. These can be derived from natural sources, such as plants (e.g., beets, paprika) or insects (e.g., cochineal, which produces carmine), or they can be synthetic dyes manufactured from petroleum. Their purpose is to make food more visually appealing or to restore color lost during processing.

Red colorings are used to enhance the visual appeal of a wide range of foods, making them look more appetizing or to meet consumer expectations for certain products. They are commonly found in confectionery, baked goods like cookies and cakes, beverages, and processed snacks. Manufacturers use them to create vibrant red shades, as seen in products like red velvet cake or holiday-themed treats.

The regulatory status and health considerations for red colorings vary significantly depending on whether they are natural or synthetic. Many natural red colorings are generally recognized as safe (GRAS) by the FDA. Synthetic red dyes, such as Red 40 and Red 3, are approved food additives by the FDA. However, the FDA revoked the use of Red 3 for food in January 2025, with manufacturers having until January 2027 to comply. In April 2025, the FDA also announced a plan to phase out petroleum-based synthetic dyes, including Red 40. Concerns have been raised, particularly in Europe, about a possible link between some synthetic food dyes and hyperactivity in children, though evidence in the US has been mixed. JECFA and EFSA have evaluated various individual red colorings and set acceptable daily intakes for many.
