Achiote seeds are the main component from the making of Annatto extract, giving an orange-yellow color from its carotenoid pigments. Kenya and Peru are the biggest annatto exporters with more that 60% of the production and distribution

The Achiote tree, original from the Amazon and some parts in Africa, provides a hard flower which contain in its insides, small reddish seeds that will derivate into two different forms of colorant: oil soluble bixin and water soluble norbixin.

The process from seeds to colorant consists in drying the seeds in the sun for hours until they bursts open. However, the drying must be controlled, because over drying it may cause loss in the pigmentation due to radiation from the sun. After they’ve been dried, the seeds are threshed and placed in a tank with 200 liters of water, and so, the precipitation process begins.
