NOVELTY - Isolating lutein from a quantity of tobacco biomass, comprises: e.g. disrupting the physical integrity of the quantity of tobacco biomass, thus forming a disrupted biomass; contacting a quantity of the disrupted biomass with an aqueous mixture optionally comprising glycine and an alkali metal salt, thus forming a first pigmented slurry; pressing a quantity of the first pigmented slurry, thus forming a pressed solid and a released syrup; and fractionating a quantity of the released syrup by force, thus forming a released syrup components having lesser and higher sedimentation velocities.    USE - The process is useful for isolating lutein from a quantity of tobacco biomass, used in: a composition; a dietary supplement and/or pharmaceutical product; a manufactured tobacco product suitable for smoking; and a smokeless tobacco product (all claimed). No biological data given.    ADVANTAGE - The method is capable of producing high levels of lutein.    DETAILED DESCRIPTION - Isolating lutein from a quantity of tobacco biomass, where the process is performed at ambient temperature, and comprises: disrupting the physical integrity of the quantity of tobacco biomass, thus forming a disrupted biomass; contacting a quantity of the disrupted biomass with an aqueous mixture having a pH of 8.5 and optionally comprising glycine and an alkali metal salt, thus forming a first pigmented slurry; pressing a quantity of the first pigmented slurry with a screw press, thus forming a pressed solid and a released syrup; fractionating a quantity of the released syrup by force, thus forming a released syrup component having a lesser sedimentation velocity and a released syrup component having a higher sedimentation velocity; contacting a quantity of an acid with a quantity of the released syrup component having a lesser sedimentation velocity, thus forming an acidified released syrup component having a pH of 5.9; contacting a quantity of the acidified released syrup component with a quantity of diatomaceous earth, thus forming a second pigmented slurry; filtering or otherwise separating the second pigmented slurry into a predominantly solid second pigmented slurry component and a predominantly liquid second pigmented slurry component; contacting a composition comprising a quantity of at least one member of the set consisting of the released syrup component having a higher sedimentation velocity and the predominantly solid second pigmented slurry component with a composition comprising at least one solvent in which lutein is soluble, thus forming a pigmented mixture; fractionating a quantity of the pigmented mixture, thus forming a fraction enriched in lutein and the solvent and a fraction in which lutein and the solvent are less abundant; and separating lutein in a quantity of the fraction enriched in lutein and the at least one solvent from the at least one solvent in the fraction enriched in lutein and the at least one solvent, thus isolating lutein from the quantity of tobacco biomass. INDEPENDENT CLAIMS are also included for:    (1) a composition suitable for ingestion by a vertebrate in need and/or desirous of ingestion, comprising lutein produced by a process and at least one excipient; and    (2) a dietary supplement and/or pharmaceutical product suitable for administration to a vertebrate, comprising lutein produced by the process and at least one suitable excipient, where the product is disposed within a suitable container-closure system.
