Abstract
Tobacco-derived components of a tobacco extract are provided by fermenting the tobacco extract within a fermentation bath. The extract may be subjected to heat treatment in a pressure controlled environment prior to and/or after fermenting. The fermented tobacco extract is then distilled at a temperatrue to provide a distillate which includes tobacco-derived components of the tobacco extract. If the extract has not previously been subjected to heat treatment, the distillate can be subjected to heat treatment in a pressure controlled environment.
Claims40
A process for altering the chemical nature of a tobacco extract thereby providing tobacco-derived components of that tobacco extract, the process comprising:
- (a) extracting tobacco material with an extraction solvent to provide a tobacco extract separate from tobacco residue insoluble in the extraction solvent;
- (b) fermenting the tobacco extract within a fermentation bath to provide a fermented tobacco extract mixture;
- (c) distilling the fermented tobacco extract mixture to provide a distillate including tobacco-derived components of the tobacco extract and
- (d) collecting, the distillate which includes distilled tobacco derived components of the tobacco extract.
A process for altering the chemical nature of a tobacco extract thereby providing tobacco-derived components of that tobacco extract, the process comprising:
- (a) extracting tobacco material with an extraction solvent to provide a tobacco extract;
- (b) fermenting the tobacco extract within a fermentation bath to provide a fermented tobacco extract mixture;
- (c) subjecting the fermented tobacco extract mixture to heat treatment in a pressure controlled environment to provide a heat treated fermented tobacco extract;
- and
- (d) distilling the heat treated fermented tobacco extract mixture to provide a distillate including tobacco-derived components of the tobacco extract.
A process for altering the chemical nature of a tobacco extract thereby providing tobacco-derived components of that tobacco extract, the process comprising:
- (a) extracting tobacco material with an extraction solvent to provide a tobacco extract;
- (b) contacting the tobacco extract with at least one sugar and/or at least one amino acid;
- (c) fermenting the tobacco extract within a fermentation bath to provide a fermented tobacco extract mixture;
- and
- (d) distilling the fermented tobacco extract mixture to provide a distillate including tobacco-derived components of the tobacco extract.
