A process for preparing a powdered water soluble beta-carotene is disclosed. The carotenoid composition is prepared by combining an aqueous solution of cyclodextrin or derivatized cyclodextrins, and a solution of beta-carotene, beta-carotene derivatives or mixtures thereof, dissolved in an organic solvent. The beta-carotene solution is added to the cyclodextrin solution with stirring for a time sufficient to remove the organic solvent. Excess beta-carotene is removed and the remaining solution is evaporated to dryness. |
