Abstract
Embodiments described herein provide a method of making a tobacco extract comprising; (a) contacting tobacco with an extraction solvent in a first chamber such that tobacco components are extracted from the tobacco into the extraction solvent, wherein the extraction solvent is a supercritical fluid in the first chamber; (b) passing the extraction solvent containing tobacco components along a line towards a second chamber, wherein a valve is present in the line and the conditions downstream of the valve are such that the extraction solvent is subcritical; and (c) pumping entrapment solvent into a flow downstream of the valve, wherein the tobacco components are released from the extraction solvent by transfer to subcritical conditions and are dissolved in the entrapment solvent, whereby the tobacco components dissolved in entrapment solvent are collected in the second chamber.
