Definitions

  • the present invention relates to a tobacco material and a tobacco product comprising the tobacco material.
  • PTL Patent Literature 1
  • PTL 2 discloses a method of improving flavor through heating of a suspension of tobacco particles by utilizing the Maillard reaction or the like (PTL 2, paragraph [0013]). Such tobacco particles are smaller than 40 mesh (PTL 2, paragraph [0024]), in other words, smaller than 400 ⁇ m.
  • a suspension of tobacco particles is also known as a raw material for a reconstituted tobacco sheet
  • PTL 3 discloses that a suspension of tobacco particles with 60 to 400 mesh is heated to 80°F to 180°F (26.7°C to 82.2°C) (PTL 3, paragraph [0056]).
  • the particle size of these tobacco particles is 38 to 250 ⁇ m.
  • the method of PTL 1 is a useful technique since flavor can be evenly imparted to tobacco shreds and the like.
  • solvent such as water
  • present inventors found a problem, for example, in which interactions and the like between water and watersoluble components derived from the tobacco raw material increase the viscosity of the dispersion, thereby making spraying of the dispersion difficult.
  • an object of the present invention is to provide a low-viscosity tobacco material in which tobacco particles are dispersed in an aqueous dispersion medium.
  • PTL 1 suggests nothing about an increase in viscosity, and PTL 2 and 3 even lack a disclosure of such particles. Accordingly, the above-mentioned problem is a problem peculiar to the use of fine particles with an average particle size of 30 ⁇ m or less and is thus a novel problem found by the present inventors.
  • the present inventors have resolved the above-mentioned problem by controlling the amount of hemicellulose to a certain value or less in a tobacco material comprising an aqueous dispersion medium and tobacco particles that are dispersed in the dispersion medium and have an average particle size of 30 ⁇ m or less.
  • the invention is set out in the appended set of claims.
  • X to Y includes the lower and the upper limits of X and Y.
  • a tobacco material of the present invention comprises an aqueous dispersion medium and tobacco particles that are dispersed in the dispersion medium and have an average particle size of 30 ⁇ m or less.
  • Tobacco particles may be derived from a tobacco raw material, a fermented tobacco raw material, or a heat-treated tobacco raw material.
  • the tobacco raw material herein means whole tobacco or parts of tobacco. As such parts, leaves, veins, stems, roots, flowers, and mixtures thereof may be used.
  • the variety of tobacco is not particularly limited, and examples include flue-cured, barley, domestic, and oriental.
  • a tobacco raw material to be used may be in the state of fresh leaves immediately after the harvest without being subjected to drying or the like, leaves that have been subjected to drying treatment after the harvest, or combinations thereof.
  • tobacco stems and veins, expanded tobacco, and sheet tobacco obtained by processing these tobacco raw materials may also be used. These materials may be used alone or in combination of a plurality of varieties or parts.
  • Tobacco particles can be prepared by any suitable method but is preferably prepared by subjecting a tobacco raw material to common drying treatment, then coarse grinding with a common coarse grinder, followed by fine grinding.
  • the drying treatment and coarse grinding may be performed in any publicly known manner, and the average particle size of coarsely ground tobacco particles preferably falls within a range from several hundred micrometers to several millimeters.
  • a method for fine grinding is also not limited, and either method of wet grinding and dry grinding may be employed.
  • the wet grinding can be performed by adding a liquid dispersion medium to coarsely ground tobacco particles, mixing, and processing the resulting mixture in a wet milling machine (MIC-2: from Nara Machinery Co., Ltd., for example).
  • the milling machine is preferably set to the rotation number of typical 1,100 to 1,300 rpm and milling time of about 5 to 100 minutes.
  • dry grinding can be performed by processing coarsely ground tobacco particles in a dry fine grinder, such as a jet mill.
  • the thus-obtained tobacco particles have an average particle size of 30 ⁇ m or less and preferably 20 ⁇ m or less. By having such average particle sizes, clogging of a nozzle is less likely to occur during spraying of a dispersion; and tobacco particles are readily and uniformly dispersed in the tobacco material. Accordingly, smoking flavor can be evenly imparted to smoking articles.
  • the lower limit of the average particle size of tobacco particles is 5 ⁇ m or more in one embodiment and 8 ⁇ m or more in another embodiment.
  • the average particle size of tobacco particles is adjustable by grinding conditions. For example, the average particle size can be increased by shortening the time for fine grinding, reducing the viscosity of a dispersion medium, and so forth.
  • the average particle size of the present invention can be determined by a laser diffraction/scattering method. Specifically, the average particle size of the present invention is measured by using a laser diffraction particle size analyzer (SALD-2100 nano particle size analyzer from Shimadzu Corporation) at a diffractive index of 1.60 to 0.101.
  • SALD-2100 nano particle size analyzer from Shimadzu Corporation

Meanwhile, the tobacco materials of the present invention, such as Example 1A, are considered to achieve a lower viscosity through extraction of a large amount of polysaccharides and the like including hemicellulose into an aqueous medium, followed by decomposition. As described above, it is clear that the tobacco materials of the present invention with a certain content or less of hemicellulose exhibit a low viscosity.
  • a hydrogen ion concentration in a slurry was measured by using a pH meter from Mettler Toledo for the tobacco materials of the present invention treated under high-temperature high-pressure conditions A and C in Example 1 [the content of tobacco particles (bone dry): 16.7% by weight]. These tobacco materials were poured into 50 mL vials and subjected to a storage test. The storage test was performed by placing the vials in a constant-temperature room at 35°C. A total viable count was measured for samples obtained immediately after the start of the storage test, after 72 hours, and after 120 hours. The total viable count was measured in accordance with the method posted on the home page of Japan Food Research Laboratories as in the following.
  • Figs. 2 and 3 These results are shown in Figs. 2 and 3 .
  • the count increases 100 to 1,000-fold during the storage in the tobacco material of Comparative Example 4 that was not subjected to high-temperature high-pressure treatment, whereas microorganisms did not proliferate even after the storage for 120 hours in the tobacco materials of the present invention.
  • Fig. 3 reveals that slurries have been changed to the environment that suppresses proliferation of microorganisms by the high-temperature high-pressure treatment.
