Preparation of finely divided, water-dispersable carotenoid formulations
First Claim
1. A process for the preparation of a water-dispersible carotenoid formulation by dissolving the carotenoid in a carrier oil at elevated temperatures until saturation is achieved to form a carotenoid solution, rapidly emulsifying the carotenoid solution with an aqueous protective colloid and then removing the water, wherein the protective colloid is a solution having a pH in the acidic range and consists essentially of a combination of a long-chain fatty acid ester of ascorbic acid and a cold water soluble starch product.

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.
