METHOD OF OBTAINING NOVEL LUTEIN-BASED FORMULATIONS

摘要

The invention relates to a method of preparing microcrystalline lutein formulations, particularly in the form of esters, which are oxidation stable and which are soluble in hydrophilic and lipophilic media. For this purpose, the lutein esters are mixed with antioxidants, vegetable oils and/or organic solvents, said initial mixture being subjected to various steps according to the type of formulation ultimately desired. Said formulations can be used directly as colouring agents as well as in the pharmaceutical, food and cosmetic fields. Moreover, the formulations can also be used as nutritional supplements.
