Yellow Lake #5

Yellow Lake #5 is a synthetic color additive. It is the insoluble lake form of Yellow #5 (Tartrazine), made by combining the dye with an inert material, often aluminum hydroxide. This process creates a pigment that is stable and dispersible in fats and oils.

It is used to add a yellow color to a wide range of foods. Manufacturers often use it in products like candy, seasoning mixes, salts, marinades, and snack foods such as popcorn and peanuts.

Yellow Lake #5 is an FDA-approved color additive for food use. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5, from food products. Some individuals may experience hypersensitivity reactions, such as hives or asthma, though scientific evidence on its impact on the general population is mixed. JECFA has evaluated Yellow 5 and set an acceptable daily intake. EFSA has also evaluated Yellow 5. There has been debate regarding a possible link between synthetic food colors, including Yellow 5, and hyperactivity in children, but scientific reviews have yielded mixed results.
