Abstract

Water-disperable carotenoid formulations are prepared by dissolving the carotenoid in a carrier oil at elevated temperatures until saturation is achieved, rapidly emulsifying the solution with an aqueous protective colloid and then removing the water, by a process in which the protective colloid used is a mixture of an ester of a long-chain fatty acid with ascorbic acid and a starch product which is soluble in cold water. The produce can be used for coloring foods and is stable to creaming.
