  • Publication number: 20030054070
    Abstract: A process for extracting carotenoids from a carotenoid-containing starting material produced by microorganisms is described. Said starting material is admixed with edible solvent to effectuate the transfer of carotenoids. Separation of the carotenoid-enriched edible solvent is improved by the formation of a “cake”, composed of said carotenoid-containing particulate solids, and, as required, a certain quantity of suitable filtration aid to modify the cake's consistency. Mechanical aids accelerate the separation of the carotenoid-enriched edible solvent. Said mixture may be hydrated to aid the removal of solids and gums from the carotenoid containing edible solvent. The carotenoid-enriched edible solvent is filtered though said cake to reduce the particulate load including any undesirable microbial load. A counter-current process increases the carotenoid concentration of the extract.
