Abstract
The present invention describes a method of preparation of formulations of microcrystalline lutein, particularly in the form of esters, which are resistant to oxidation and are soluble in hydrophilic and/or lipophilic media. For these formulations, the esters of lutein are mixed with antioxidants, vegetable oils and/or organic solvents, and this initial mixture is submitted to various stages depending on the type of final formulation required. These formulations are suitable for direct application as colourants in the pharmaceutical, food and cosmetics fields. They can also be used as diet supplements.
