Blue 1 And 2

Blue 1 and Blue 2 are synthetic color additives used in food. They are made from petroleum. Blue 1 is also known as Brilliant Blue FCF, and Blue 2 is known as Indigotine.

These dyes are added to foods to give them a blue color. They are commonly found in products like cereals, cakes, cupcakes, snack cakes, and beverages. Their purpose is purely cosmetic, making foods more visually appealing.

Blue 1 and Blue 2 are approved color additives by the U.S. Food and Drug Administration (FDA). In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1 and Blue 2. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes. Some research has suggested a possible link between synthetic food dyes and hyperactivity in some children, though the evidence is mixed. The FDA maintains that current scientific evidence does not show a causal link for the general population, but acknowledges that certain children may be sensitive.
