A process for obtaining ethereal oils and / or of the components essential oils from moist extraction material

摘要

The invention relates to a process for obtaining ethereal oils and / or of the components essential oils from moist extraction material containing essential oils and / or components of ethereal oils, by extraction of the wet extraction material with an extraction agent mixture, consisting of at least one polar and at least a nonpolar solvent to obtain a miscella, wherein the extraction material is selected from the shells of citrus fruits and / or residual substances from the juice production from citrus fruits and / or herbs, wherein the extraction material a residual moisture content of from 5 to 95 ma -%, measured on the total mass of the extraction material, wherein the extracting agent (at least a non-polar solvent to a proportion of from 45 to 95 vol. -%, measured on the total volume of the extraction agent mixture, wherein the extracting agent (a temperature above the ambient temperature, however, below the boiling point of the lowest boiling solvent or of the lowest boiling azeotropic of the extracting agent comprises. Optionally, makes it possible for the coarse separation of polar and non-polar components of the ethereal oil.
