Definitions

  • the present invention relates to a method of manufacturing a regenerated tobacco material.
  • Tobacco materials such as natural tobacco leaves, cut tobacco, midribs, stems and roots contain various components including nicotine, nitrosamines, hydrocarbons and proteins.
  • these components extracted from a natural tobacco material, are put back to a regenerated tobacco web manufactured from a residue of the extraction.
  • Some of these natural tobacco material components should desirably be reduced in amount or removed, while other ones should not be removed or even increased in amount, for a reason of smoking flavor or some other reason.
  • U.S. Patent 5,810,020 discloses that nitrosamines are removed by a liquid-liquid extraction treatment using a great amount of crown ether.
  • Nitrosamines, TSNAs in particular, contained in natural tobacco materials are substances which should desirably be eliminated.
  • TSNAs are similar in structure to nicotine, which is a useful component, and therefore it is very difficult to remove TSNAs selectively without removing nicotine.
  • the present invention provides a method of manufacturing a regenerated tobacco material using an extract solution obtained by extraction from a natural tobacco material with an aqueous extracting solvent, and an extraction residue.
  • a method of manufacturing a regenerated tobacco material comprising (a) extracting a natural tobacco material with an aqueous extracting solvent to obtain an extract solution containing components of the natural tobacco material, and an extraction residue, (b) subjecting the extract solution to an adsorption separation operation using an adsorbent to reduce an amount of nitrosamines, (c) preparing a regenerated tobacco web using the extraction residue, and (d) adding at least a part of the extract solution, in which the amount of nitrosamines has been reduced, to the regenerated tobacco web, wherein the adsorbent is a strongly hydrophobic adsorbent, and the adsorption separation operation is carried out within 60 minutes, using the strongly hydrophobic adsorbent in an amount corresponding to 10 to 110% of the weight of soluble components in the extract solution.
  • the single figure is a flow diagram illustrating a method of manufacturing a regenerated tobacco material according to an embodiment of the present invention.
  • the present invention is a method of manufacturing a regenerated tobacco material by substantially removing TSNAs (N'-nitrosonornicotine (NNN), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), N'-nitrosoanatabine (NAT), etc.) from an extract solution obtained by extracting a natural tobacco material with an aqueous extracting solvent while suppressing loss of nicotine as much as possible, and adding the extract solution to a regenerated tobacco web prepared by using the extraction residue.
  • TSNAs N'-nitrosonornicotine
  • NNK 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone
  • NAT N'-nitrosoanatabine
  • FIG. 1 is a flow diagram illustrating a method of manufacturing a regenerated tobacco material according to an embodiment of the present invention.
  • the extraction mixture obtained is subjected to a separation operation S2 such as filtration to separate it into an extract solution 13 and an extraction residue 14.
  • the extract solution 13 contains watersoluble components in the natural tobacco material, such as nicotine and TSNAs.
  • the contact between the extract solution 13 and the strongly hydrophobic adsorbent can be achieved by adding particles of the strongly hydrophobic adsorbent to the extract 13, followed by stirring.
  • the contact between the extract 13 and the strongly hydrophobic adsorbent can be achieved by passing the extract solution 13 through an adsorbent bed filled with particles of the strongly hydrophobic adsorbent.
  • the contact time between the extrac solution 13 and the strongly hydrophobic adsorbent is within 60 minutes. When the contact time is within 60 minutes, TSNAs can be eliminated while significantly suppressing the adsorption of nicotine.
  • the contact time is preferably 5 to 60 minutes, and more preferably, 5 to 30 minutes.
  • the thus obtained extract 16 already subjected to the adsorption treatment is added (S5) partially or entirely to the regenerated tobacco web 15 after concentrating or without concentrating the extract, and thus a regenerated tobacco material 18 can be obtained.
  • a cigarette manufactured using the regenerated tobacco material 18 thus obtained exhibits a significantly reduced amount of TSNAs in the smoke when it is burned.
  • TABLE 1 Amount of adsorbent (%) Adsorption treatment time (min) Total amount of TSNAs ( ⁇ g/g) Amount of nicotine (mg/g) Rate of change in total TSNAs (a) Rate of change in nicotine (b) Difference (a-b) Untreated - - 30.5 23.4 - - - Ex. 1 13 15 11.8 17.2 -61% -26% -35% Ex. 2 13 30 10.0 16.4 -67% -30% -37% Ex. 3 13 60 8.9 14.1 -71% -39% -31% Ex.
  • the extracts subjected to the adsorption treatment in Examples 1 - 3 and 5 - 6 were added to the regenerated tobacco webs, respectively, preparing regenerated tobacco materials.
  • the extracts subjected to the adsorption treatment in Examples 9 - 11 were added to the regenerated tobacco webs, respectively, preparing regenerated tobacco materials.
  • the extracts subjected to the adsorption treatment in Examples 12 - 14 were added to the regenerated tobacco webs, respectively, preparing regenerated tobacco materials.
  • the cut tobacco was extracted in accordance with the procedures of Examples 1 - 8, and the extracts thus obtained were adjusted to a pH of 2.0 or 10.0 by adding acid (acetic acid) or alkali (sodium hydroxide).
  • the extracts were treated with activated carbon used in Examples 12 - 14 under respective conditions indicated in TABLE 4.
  • the results of the analysis of the total amount of TSNAs and amount of nicotine contained in the extract (filtrate) after the adsorption treatment were also indicated in TABLE 4.
  • the present invention it is possible to separate nicotine and TSNAs from an extract solution obtained from a natural tobacco material in a relatively simple manner, and to manufacture a regenerated tobacco material substantially freed of TSNAs while suppressing the loss of nicotine as much as possible.
