E160Bii Colour

Annatto is a natural food colouring derived from the seeds of the achiote tree (Bixa orellana). The seeds are processed to extract the carotenoid pigments, primarily bixin and norbixin, which give the characteristic orange-red colour. It is commonly supplied as a liquid extract or powder.

Annatto is used to impart a yellow to deep orange colour to a variety of foods. It is frequently found in cheeses, dairy products, baked goods, and processed meats. Its primary function is as a colourant, enhancing the visual appeal of food products.

Annatto (E160B) is an authorised food additive in the UK and is listed on the Register of Food Additive Authorisations. European food safety authorities, including EFSA, have evaluated annatto and established acceptable intake levels. At typical consumption levels found in food, it is not associated with adverse health effects. Some individuals may experience allergic reactions, though this is rare.
