Blue #1 Lake And Red #40 Lake

Blue #1 Lake and Red #40 Lake are synthetic color additives. They are pigments made by combining the water-soluble dyes Blue #1 and Red #40 with an insoluble material, typically aluminum hydroxide. This process creates a stable, non-dissolving color that can be used in various food products.

These lakes are added to foods to provide vibrant blue and red colors. Because they are insoluble, they are especially useful for coloring products with low moisture content, high fat content, or where the color needs to be dispersed rather than dissolved. They are commonly found in baked goods like cakes, cupcakes, and snack cakes.

Blue #1 Lake and Red #40 Lake are approved by the FDA as color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue #1 and Red #40. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes. Some studies have suggested a link between synthetic food dyes and hyperactivity in some children, but the evidence is mixed. The FDA states that for most children, there is no proven link, but for some children with behavioral problems, avoiding these dyes may be helpful.
