Blue 1 And Blue 2

Blue 1 (also known as Brilliant Blue FCF) and Blue 2 (also known as Indigotine) are synthetic color additives. They are manufactured from petroleum-based chemicals through a chemical synthesis process.

These dyes are used to impart a blue color to a wide range of food products. They are frequently found in candies, snacks, beverages, dairy products, and baked goods to enhance their visual appeal.

Blue 1 and Blue 2 are color additives approved by the U.S. Food and Drug Administration (FDA) for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1 and Blue 2, from food products. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated both Blue 1 and Blue 2 and established an acceptable daily intake. The European Food Safety Authority (EFSA) has also evaluated these dyes. There has been mixed evidence and debate regarding a possible link between synthetic food dyes and hyperactivity or other behavioral issues in some children. The FDA has reviewed the available scientific evidence and concluded that there is no conclusive link, but acknowledges that some children may be sensitive to food dyes.
