What is Annatto?

Annatto is a natural food coloring agent and condiment that is extracted from the seeds of the achiote fruit. The achiote tree (Bixa Orellana) is a tropical shrub or small tree that grows in Central and South America. The flowers of this tropical tree are white or bright pink, but the fruit is the most desirable part of the plant, made up of spiky brown and red pods that grow in clusters. When those pods dry and crack open, they expose seeds of red color, from which red pigment can be extracted. This is why the achiote tree is often called the lipstick tree. It is also called chitoe, onoto, bija, colorau, urucum, or atsuete in different regions.

Annatto’s strong pigmentation makes it a natural dye that may range from yellow to deep orange to red, and it has plenty of applications in cosmetics.  It is also used as a condiment in certain parts of the world. It has a floral and nutty smell and is mildly peppery to taste. In the Caribbean and Central American cultures, annatto has been used for thousands of years to treat everything from mild to potentially life-threatening diseases, making it an ancient “superfood”.
