Red 40 And Yellow 5

Red 40 (also known as Allura Red AC) and Yellow 5 (also known as Tartrazine) are synthetic color additives. They are petroleum-derived and produced through chemical synthesis.

Manufacturers add these dyes to provide bright red and yellow colors to foods and beverages. They are commonly found in candies, snacks, soft drinks, and desserts to enhance visual appeal.

Both Red 40 and Yellow 5 are approved by the FDA as color additives for food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40 and Yellow 5. Concerns about these dyes causing hyperactivity in some children have been raised, with scientific evidence showing mixed results. JECFA has evaluated both dyes and set acceptable daily intakes. Some individuals may experience allergic-type reactions to Yellow 5, though this is rare.
