Red 40 And Red 3

Red 40 (Allura Red AC) and Red 3 (Erythrosine) are synthetic food colors. Red 40 is derived from petroleum, while Red 3 is a coal-tar dye. They are manufactured to provide specific red hues in food products.

These dyes are added to foods to enhance their visual appeal and provide a consistent red color. They are commonly found in candies, beverages, baked goods, and other processed foods where a vibrant red is desired. Their primary function is to act as a color additive.

Red 40 is an FDA-approved color additive, though 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. Some studies have suggested a possible link between synthetic food colors like Red 40 and hyperactivity in some children, but the scientific evidence is mixed. Red 3 was revoked by the FDA for food use in January 2025, with manufacturers having until January 2027 to remove it from products. This revocation was due to the Delaney Clause, as it caused cancer in male rats, though the FDA stated this is not relevant to human risk. California's Food Safety Act also bans Red 3 in food from 2027. JECFA has evaluated Red 3 and set an acceptable daily intake.
