The parent of annato dye is a shrub native to tropical
locations. This is called Bixa Orellana. It is now naturalised in India in forest areas. Colours which are permitted to be
added to food and edible materials are food colours. These are usually harmless, water soluble or oil soluble and added to
butter and similar foods.
The main use is to distinguish margarine etc., from other
milk products. Annato dye is widely used for colouring of food materials like dairy products, oils and bakery products. More
of it is used in cosmetics preparation like lip-sticks, furniture, dyeing of leather and shoe polishes etc. It is also used
in sun tans, floor wax, etc.
