Abstract
In a method for extracting ingredients, particularly foreign substances, from liquids or solids dispersions by using compressed extraction agents such as, for instance, supercritical or liquid carbon dioxide, the liquid or dispersion is applied as a thin film in a pressure-tight reactor and the surface of the thin film is treated with the extraction agent, particularly carbon dioxide, wherein the surface of the thin film is constantly renewed over at least a portion of the layer thickness of the thin film by mechanically acting on said liquid or dispersion.
