Annatto (Bixa orellana L.)

Background

  • Annatto is a pigment, or dye, produced from the red seeds of the achiote (Bixa orellana) tree. Achiote is native to the tropics of North and South America, the Caribbean, and the East Indies. It is cultivated in South America and Southeast Asia. Annatto has long been a staple of Latin American and Caribbean cuisines as a flavoring and coloring agent. Annatto adds a slightly sweet and peppery taste and yellow or red color.
  • Achiote is known as the "lipstick tree" because the seeds have been used by Central and South American natives to make lip color, as well as body paint and fabric dye.
  • Achiote has been used as a traditional remedy for a variety of conditions, including diabetes, jaundice, snakebite, indigestion, heartburn, and hypertension (high blood pressure). All parts of the plant have been used, including the roots, leaves, seeds, and dried pulp of the fruit. Recently, annatto has been included as an ingredient in weight-loss products.
