Red40

Red 40, also known as Allura Red AC, is a synthetic food dye. It is produced from petroleum. Its purpose is to give foods a red color.

Manufacturers add Red 40 to enhance the visual appeal of foods and beverages. It is commonly found in soft drinks, candies, cereals, baked goods, and dairy products. Its use ensures a consistent and vibrant red color in processed foods.

Red 40 is an FDA-approved color additive for food use. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40. JECFA has evaluated Red 40 and set an acceptable daily intake. EFSA has also evaluated it. Some studies suggest a possible link between synthetic food dyes, including Red 40, and hyperactivity in some children, though evidence is mixed and more research is ongoing.
