Abstract:
1. A method of creating a microcrystalline carotenoid preparation for oral ingestion, comprising the following steps: a. mixing a selected carotenoid in a suitable selected non-aqueous solvent, to create a solvent-carotenoid liquid mixture; b. mixing the solvent-carotenoid liquid mixture with an oily carrier liquid that is non-toxic and orally ingestible, thereby creating a solvent-carotenoid-carrier liquid mixture; c. passing the solvent-carotenoid-carrier liquid mixture and a stream of inert gas through a spray nozzle causing a mist to emerge, said mist contacting one or more solid surfaces designed for condensate collection, in a manner which (i) causes the mist to form a liquified condensate which can be collected, and (ii) allows the gas and the solvent to be removed from the liquified condensate, wherein the liquified condensate contains the selected carotenoid in a form having average particle sizes less than about 10 microns, in an oily carrier liquid.
