Annatto seed, also known as Cari seed, is derived from the pods of the Bixa orellana tree, a tropical plant native to Central and South America and widely cultivated in Southeast Asia. Annatto is best known as a natural food coloring, valued for its bright yellow-orange to reddish hue, but its uses go far beyond coloring.
Today, annatto seeds are widely used in the food, cosmetic, pharmaceutical, textile, and animal feed industries, thanks to their natural pigments and bioactive compounds.
