PROCEDURE FOR OBTAINING NEW FORMULATIONS BASED ON LUTEINE.

摘要

The present invention describes a process for preparing microcrystalline lutein formulations, particularly in the form of esters, stable to oxidation and soluble in hydrophilic and / or lipophilic media. For them, the lutein esters are mixed with antioxidants, vegetable oils and / or organic solvents, this initial mixture being subjected to various stages according to the type of formulation that is finally desired to be obtained. These formulations are of direct application as colorants both in the pharmaceutical, food and cosmetic fields. They can also be used as nutritional supplements.
