Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Gewinnung von Pflanzen-Inhaltsstoffen, kurz Aromen, in möglichst unveränderter Naturform aus Biomaterial durch Kondensation und/oder Absorption unter Verwendung eines Extraktors, eines Verdichters und einer oder mehrerer Drosselventile und eines Sammelraums.Extracting flavors from a biomaterial comprises: providing the biomaterial in an extractor and passing a gas stream through the biomaterial directing the gas stream in a collection chamber over/by an absorbent and/or introducing water vapor into the extractor and condensing the gas stream containing the water vapor in a collection chamber and recycling the gas stream and supplied into the collection chamber from the extractor by a compressor and recycling the gas stream into the extractor from the collection chamber via a throttle valve. Extracting flavors from a biomaterial comprises: providing the biomaterial in an extractor and passing a gas stream through the biomaterial directing the gas stream in a collection chamber over or by an absorbent and/or introducing water vapor into the extractor and condensing the gas stream containing the water vapor in a collection chamber, where the pressure in the collection chamber is greater than the pressure in the extractor and recycling the gas stream and supplied into the collection chamber from the extractor by a compressor and recycling the gas stream into the extractor from the collection chamber via a throttle valve.
