About annatto

Annatto is the name given to the Bixa orellana L. plant. Its seeds are covered by a pigment widely used by the food, pharmaceutical and cosmetic industries. Their pigments were already used by the Brazilian indians before the discovery. The first reference to the annatto can be attributed to Pero Vaz de Caminha's letter to Portugal king D. Manuel, informing the discovery of Brazil. Did you know that the Aztecs, ethnic groups of central Mexico, mixed annatto dye with cocoa to produce a drink and used it in their rituals, simulating human blood.
