Therefore, in order to achieve the desire color, poultry and feed producers usually combine a yellow carotenoid in the diet by adding natural lutein (apo-ester, lutein, or zeaxanthin), a synthetic red one (canthaxanthin) and orange-II, which is a banned dye belonging to a class of organic compounds known as azo-dyes (Mollah et al.

We think that for all these reasons (purity, quality, reliable supply and excellent price/performance ratio) using nature-identical beta-carotene and lycopene is the best way to replace azo-dyes with red, yellow or orange colour.
