Yellow #5 Dye

Yellow #5, also known as Tartrazine, is a synthetic food dye that gives products a yellow color. It is an azo dye, which means it is created through a chemical reaction involving nitrogen compounds. This dye is manufactured from petroleum.

Manufacturers add Yellow #5 to foods to provide a bright yellow color. It is commonly found in a wide range of products, including candies, baked goods, beverages, snack foods, and dessert toppings.

Yellow #5 is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow #5. Some studies have suggested a possible link between synthetic food dyes, including Yellow #5, and hyperactivity in some children, though the evidence is mixed and more research is ongoing. JECFA has evaluated Yellow #5 and set an acceptable daily intake. EFSA has also evaluated this additive.
