Definitions

  • a volatile apolar solvent examples include cyclic or acyclic short alkanes, as well as chlorinated solvents like dichloromethane.
  • the excess solvent may be evaporated by controlled heating under vacuum. Typically, this is done in the presence of ethanol, which has a higher boiling point than the extraction solvent, such that even traces of the extraction solvent can be detected.
  • the term “atomised water” refers to water that has been reduced into a plurality of small liquid droplets.
  • the atomised water is therefore in an aerosolised form, with the plurality of water droplets suspended in air or another gas.
  • spraying refers to the step of discharging a flow or stream of the atomised water into the extraction chamber, at or above atmospheric pressure.
  • the heating step may be carried out under vacuum. This removes any oxygen present within the extraction chamber, which may advantageously prevent reaction of the tobacco material or volatile compounds generated upon heating of the tobacco material with oxygen. The removal of oxygen will also prevent any combustion of the tobacco material, as described above.
  • natural tobacco is used herein with reference to the present invention to describe any part of any plant member of the genus Nicotiana, including, but not limited to, leaves, midribs, stems and stalks.
  • the natural tobacco may comprise flue-cured tobacco material, Burley tobacco material, Oriental tobacco material, Maryland tobacco material, dark tobacco material, dark-fired tobacco material, Rustica tobacco material, as well as material from other rare or specialty tobaccos, or blends thereof.
  • the tobacco material may be whole (for example, whole tobacco leaves), shredded, cut or ground.
  • impregnation of the tobacco material with a non-aqueous extraction solvent that is also an aerosol former, such as propylene glycol, vegetal glycerin, 1 ,3-propanediol, triacetin, or mixtures thereof has been found to advantageously increase the amount of flavour compounds that are extracted from the tobacco material.
  • the non-aqueous solvent content may be at least about 5 percent by weight or at least about 10 percent by weight or at least about 15 percent by weight or at least about 20 percent by weight or at least about 25 percent by weight or at least about 30 percent by weight or at least about 35 percent by weight or at least about 40 percent by weight.
  • the step of collecting the volatile compounds uses an absorption technique in which the volatile compounds are trapped in a non-aqueous extraction liquid solvent.
  • a non-aqueous extraction liquid solvent is preferably an aerosol former such as triacetin, glycerin, 1 ,3-propanediol, propylene glycol or combinations thereof.
  • aerosol former such as triacetin, glycerin, 1 ,3-propanediol, propylene glycol or combinations thereof.
  • the use of an aerosol former as the liquid solvent is potentially beneficial because the aerosol former can be retained as a diluting agent in the final liquid tobacco extract. This means that an additional step of removing the non-aqueous extraction solvent is not necessarily required.
  • the liquid tobacco extract may comprise from about 30 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 65 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the liquid tobacco extract may comprise from about 30 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 60 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the liquid tobacco extract may comprise from about 30 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 55 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the liquid tobacco extract may comprise from about 35 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 65 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the liquid tobacco extract may comprise from about 35 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 60 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the liquid tobacco extract may comprise from about 35 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract to about 55 percent by weight of the non-aqueous extraction solvent based on the weight of the liquid tobacco extract.
  • the non-aqueous extraction solvent is preferably triacetin, glycerin, propylene glycol, 1 ,3-propanediol or a mixture thereof.
  • the nicotine composition may comprise a total content of 1 ,3-propanediol of from about 10 percent to about 95 percent by weight.
  • the nicotine composition may comprise a total content of 1 ,3-propanediol of from about 20 percent to about 95 percent by weight, such as from about 50 percent to about 95 percent by weight, or from about 65 percent to about 95 percent by weight, or from about 80 percent to about 90 percent by weight.
