Yellow 5, also known as tartrazine, is a synthetic food dye commonly used to add a bright yellow color to various products. It is often found in soft drinks, candies, and processed foods. Yellow 5 is made from coal tar and is part of a group of dyes known as azo dyes. In the United States, Yellow 5 is approved by the Food and Drug Administration (FDA) for use in food and beverages. While it is generally considered safe, some individuals may experience allergic reactions or sensitivities to it. As a result, products containing Yellow 5 are required to list it in their ingredient labels.
