FOOD PRODUCTS, NUTRACEUTICALS, AND PHARMACEUTICALS PRODUCED FROM SELECTIVE EXTRACTION OF CARBONACEOUS MATERIALS

摘要

Novel foods, nutraceuticals, and pharmaceutical products are produced from conventionally known solvent extraction comprising contact of the oil-bearing material (material bed 14) with a normally gaseous solvent (vessel 1) within an extraction zone maintained at temperatures and pressures that cause the solvent to remain a liquid. The improvement over the conventionally known extraction process is the addition of a gas (vessel 3) into the extraction zone (vessel 5) which at a givent pressure liquifies at a higher temperature than the solvent wherein the temperature and pressure within the extraction zone is suficient to cause the solvent to liquify when the solvent is introduced into the extraction zone.
