Product Descriptions:

Annato is an orange-red condiment and fabric colouring derived from the seeds of the achiote tree (Bixa Orellana). It is often used to impart a yellow or orange colour to fabrics. Annato is mainly native to tropical America. The seeds are covered with a reddish aril, which is the source of an orange-yellow dye. Annatto paste is also used as a natural dye for cloth and wool and is sometimes also used in painting, varnish, lacquer, cosmetic, and soap In annatto mainly bixin and norbixin are found in the reddish waxy coating of the seeds. The paste is mainly produced by grinding the achiote seeds. Similar effects can be obtained by extracting some of the colour and flavour principles from the seeds with hot water, oil, or lard, which are then added to the food or fabrics.
