Base formulation prospection of a colloidal beverage mimic system added with lutein

Abstract

Lutein daily intake is related to the maintenance of visual and cognitive health. The incorporation of this lipophilic compound into an aqueous matrice requires the use of an emulsion as a carrier system. Lutein was extracted from marigold petals by supercritical fluid extraction, using sunflower seed as co-solvent at 3 different temperatures. Extraction efficiency was evaluated through the total carotenoid content. A colloidal beverage mimic system was prepared with an oil-in-water emulsion formulated with carotenoid extracts, and it was preliminarily observed that there was degradation of the carotenoids during 15 days of refrigerated storage.
