Blue 1 & 2 Lake

Blue 1 Lake and Blue 2 Lake are synthetic color additives. They are the insoluble forms of Brilliant Blue FCF (Blue 1) and Indigotine (Blue 2) dyes, made by combining the dye with an aluminum salt. This process makes the color more stable and less likely to bleed in certain food applications.

These ingredients are used to add blue color to foods, especially those with low moisture content or high fat, where water-soluble dyes might bleed. They are commonly found in candies, baked goods, and snacks to achieve vibrant blue hues.

Blue 1 Lake and Blue 2 Lake are approved color additives by the FDA for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Blue 1 and Blue 2. JECFA has evaluated Brilliant Blue FCF (Blue 1) and Indigotine (Blue 2) and established acceptable daily intakes. EFSA has also evaluated these dyes and concluded they are safe at specified levels. Some studies have suggested a link between synthetic food dyes and hyperactivity in children, but the evidence is mixed, and regulatory bodies generally consider them safe at permitted levels.
