Abstract:
Embodiments described herein include a method of making a tobacco extract comprising; (a) providing tobacco and an entrapment solvent in a partitioned vessel, wherein the tobacco and entrapment solvent are separated by the partition, and the vessel is configured such that the tobacco and entrapment solvent cannot contact each other; (b) flowing a supercritical extraction solvent through the vessel, wherein the extraction solvent and any dissolved substances can pass through the partition; whereby tobacco components are extracted from the tobacco into the extraction solvent and carried across the partition, wherein the extraction solvent contacts the entrapment solvent and tobacco components are transferred from the supercritical extraction solvent into the entrapment solvent.
