And FD&C Yellow No. 5 Lake

FD&C Yellow No. 5 Lake is a synthetic color additive derived from FD&C Yellow No. 5, also known as Tartrazine. It is produced by reacting the dye with a metallic salt, typically aluminum, to create an insoluble pigment. This process makes it more stable and suitable for coloring fats, oils, and dry products.

This ingredient is used to impart a yellow color to a wide variety of food products. As a lake pigment, it disperses rather than dissolves, making it ideal for use in items with low moisture or high fat content, such as seasoning mixes, salts, marinades, and baked goods.

FD&C Yellow No. 5 Lake is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow No. 5. Some studies have suggested a possible link between synthetic food dyes, including Yellow No. 5, and hyperactivity in some children, though the evidence is mixed. JECFA has evaluated Yellow No. 5 and established an acceptable daily intake. EFSA has also evaluated it and concluded that the available data do not establish a causal link between Yellow No. 5 and hyperactivity, but noted that some studies suggest a possible link in sensitive children.
