Annatto extracts occur as dark red solutions, emulsions, or suspensions in water or oil or as dark red powders. The extract is prepared from annatto seeds, Bixa orellana L., using a food-grade extraction solvent. Bixin is the principal pigment of oil-soluble annatto extracts. Norbixin is the principal pigment of alkaline water-soluble annatto extracts.
Annatto extracts have been used for over two centuries as a food color, especially in cheese, and various types are now used in a wide range of food, drugs and cosmetic products, including butter, margarine, salad dressing, ice cream and other frozen desserts, confectionery, egg products, fish and fish products, meat products, cereals, cakes, beverages, soup mixes, fruit products, snacks, bakery products, spices and seasonings, and sausage casings.
The Codex Alimentarius Commission has finalized adoption of MPLs for Annatto extracts, bixin-based (160b(i)) in 6 food categories and for Annatto extracts, norbixin-based (160b(ii)) in 7 food categories. A large number of other applications of annatto extracts, both bixin and norbixin-based as a color additive in foods and beverages have been proposed and are pending adoption, following completion of the review and comments process.
