Artificial Colors Red #40 And Blue #1

Red #40 (Allura Red AC) and Blue #1 (Brilliant Blue FCF) are synthetic color additives. They are petroleum-derived and produced through chemical synthesis. These dyes are used to impart a vibrant red and blue color, respectively, to various food products.

Manufacturers add these artificial colors to enhance the visual appeal of foods and beverages. They are commonly found in candies, cereals, baked goods, soft drinks, and snack foods, including popcorn, peanuts, and chocolate products.

Red #40 and Blue #1 are approved by the FDA as food additives. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red #40 and Blue #1. JECFA has evaluated both dyes and set acceptable daily intakes, and EFSA has also evaluated them. Concerns have been raised about a possible link between synthetic food dyes and hyperactivity in some children; however, the evidence is mixed, and the FDA states that current evidence does not support a causal link for the general population, though some sensitive children may show behavioral effects.
