Quinoline Yellow and the Alpha-Gal Friendly Diet
Quinoline Yellow is a synthetic dye commonly used to impart a yellow to greenish-yellow color in food products. It is derived from coal tar and is often used in powdered drink mixes, candies, and desserts. While chemically manufactured, some production processes may involve animal derivatives, which is why vegans and those with specific dietary restrictions may need to verify the source with manufacturers.
