ABSTRACT:
A carotenoid-enriched fraction is extracted from natural sources, such as carrots, by (i) separating the carotenoid-containing natural source into a carotenoid-containing liquid fraction and a pulp fraction, (ii) adding a carotenoid precipitation agent including calcium chloride, calcium hydroxide, calcium lactate or calcium gluconate to the liquid fraction to form a carotenoid-enriched solid precipitate, and (iii) separating the carotenoid-enriched solid precipitate from the carotenoid-depleted liquid portion.
