  • Patent number: 8887737
    Abstract: A method of forming a liquor comprising tobacco solutes, the method comprising extracting tobacco solutes from tobacco by flowing an extraction solvent through tobacco to form a tobacco solutes-rich extraction solvent and a tobacco solutes-poor tobacco, and forming tobacco solutes-rich liquor by flowing the tobacco solutes-rich extraction solvent through an entrapment solvent, wherein the tobacco solutes comprise nicotine and at least one tobacco flavor compound and/or tobacco aroma compound and the liquor comprises the tobacco solutes dissolved in the entrapment solvent. A preferred extraction solvent comprises a supercritical fluid. Also provided are cigarettes and cigarette components comprising extracted tobacco solutes such as flavor compounds, aroma compounds and nicotine. Further, tobacco from which aroma compounds and/or nicotine have been extracted can be used in cigarettes.

  • Patent number: 8839801
    Abstract: Method of manufacturing a cigarette having equivalent aroma and flavor even with a reduced amount of burley leaves. The method does not require special processing treatment due to the absence of necessity of an installation space and costs for the treatment. Also, method of manufacturing a cigarette containing the same, and a cigarette. The invention separates raw material for sheet tobacco into fiber and solution, adds a primary casing flavor to the solution, mixes the solution added with the primary casing flavor and the fiber to produce a mixture, and dries the mixture. Burley leaf tobacco is thereafter mixed with the sheet tobacco. The casing flavor is previously added at the time of the molding of sheet tobacco in the sheet-tobacco manufacturing process, which makes enables production of sheet tobacco having the aroma and flavor equivalent of when burley leaf tobacco is used, even without special processing treatment.

  • Publication number: 20140261482
    Abstract: A method for reducing the tobacco specific nitrosamines (TSNAs) in tobacco and tobacco smoke is provided. The tobacco is combined with a solvent to form a soluble extracts fraction and an insoluble residue fraction. The soluble extracts fraction is contacted with a nitrosamine-reducing material to provide a soluble extracts fraction having a reduced level of TSNAs. The nitrosamine-reducing material may comprise a sepiolite. The insoluble residue fraction is contacted with an alkali extractant to provide an insoluble residue fraction having a reduced level of TSNAs. The alkali extractant may comprise a hydroxide. The soluble extracts fraction having a reduced level of TSNAs and insoluble residue fraction having a reduced level of TSNAs may be recombined to form a reconstituted tobacco product having a reduced level of TSNAs. The TSNAs may be reduced by at least about 30%, such as at least about 40%, such as at least about 50%.
