Annatto, or norbixin, is extracted from the Bixa orellana or lipstick tree; it gives a yellow to deep orange color. The plant has entered into commercial cultivation for the production of this dye, which is used mainly in the food industry and for coloring dairy products such as butter and cheese, margarine and edible oils.
