Pet Food

Food coloring is occasionally used in pet food, such as dog and cat food, to enhance its appearance and make it more appealing to pet owners. Some common food colorings used in pet food include caramel coloring, which is used to darken the appearance of the food, and beta-carotene, which is used to give a yellow or orange color to the food. In the United States, food coloring used in pet food must be approved by the Food and Drug Administration (FDA) and must be labeled on the product's ingredient list.
