Tartrazine And Red 40

Tartrazine (also known as Yellow 5) and Red 40 are synthetic food dyes made from petroleum. They are used to add color to a wide variety of foods and beverages.

These dyes are added to foods to achieve specific yellow and red hues, or to create other colors when mixed. They are commonly found in candies, desserts, beverages, and processed snacks to make them more visually appealing.

Both Tartrazine (Yellow 5) and Red 40 are approved color additives by the FDA. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red 40 and Yellow 5. Some studies have suggested a link between synthetic food dyes and hyperactivity in some children, though the evidence is mixed. JECFA has evaluated both Tartrazine and Red 40 and set acceptable daily intakes.
