Annatto extract Bixin is listed as a color additive exempt from certification (Title 21 Code of Federal Regulations part 73) and is commonly considered to be a natural color. The yellowish orange color is produced by the compounds bixin and norbixin, which are classified as xanthophylls, a type of carotenoid. However, unlike beta-carotene, another well-known carotenoid, they do not have the correct chemical structures to be vitamin A precursors. The more norbixin in an annatto color, the more yellow it is; a higher level of bixin gives it a more reddish shade. Unless an acid-proof version is used, it takes on a pink shade at low pH.
