Definitions
- the present invention relates to a flavor inhaler.
- acetate filters are usually used, in which cellulose acetate fibers are filled inside a tubular wrapper as filtering materials.
- cellulose acetate fibers are semi-synthetic fibers, and therefore they have low dispersibility and degradability when, for example, the flavor inhaler is disposed of, resulting in a heavy burden on the natural environment. Therefore, from the viewpoint of reducing environmental burden, development of a filter using natural fibers has been desired.
- Filters containing natural fibers include, for example, paper filters that contain paper made of plant pulp as filtering materials.
- the paper filter has different filtration characteristics from acetate filters in terms of smoke components, and the paper filter tends to remove more particle phase components and less vapor phase components, compared to the acetate filters. Due to this filtration characteristic, flavor inhalers provided with paper filters tend to have less umami taste components in the flavor and evoke a feeling of discomfort, thereby desiring the improvement of flavor quality.
- Patent literatures 1 and 2 disclose, for examples, a method for adding additives such as a polyalkylene glycol and triacetin to a paper filter, as a method for approximating filtration characteristics of paper filters to those of acetate filters.
- Patent Literature 3 discloses a method for obtaining an extract from a tobacco raw material with a specific ratio of saccharide content and glutamine content and pouring the extract back over a sheet formed of a residue after extraction, for the purpose of producing sheet tobacco with a low amount of formaldehyde to be generated.
- Patent Literatures 1 and 2 the method for adding additives to filters as disclosed in Patent Literatures 1 and 2 is complicated in terms of the manufacturing process and management thereof and may cause poor gluing of various wrappers and dissolution of inks due to additive seepage, which may result in lowering product quality. Therefore, the method necessitates advanced technology in controlling the physical properties of the additive and in the additive technology and therefore is not practical.
- Patent Literature 3 does not disclose a flavor inhaler provided with a filter containing natural fibers.
- An object of the present invention is to provide a flavor inhaler that is provided with a filter containing natural fibers and has improved flavor quality.
- the present invention includes the following embodiments.
- the flavor inhaler according to the first embodiment of the present invention is provided with a tobacco-containing segment and a first filter segment.
- the tobacco-containing segment includes a tubular wrapper and a tobacco filling filled inside the wrapper.
- the first filter segment is also provided with a filter containing natural fibers.
- the tobacco-containing segment contains trisaccharides composed of glucose, fructose, and sucrose, and tri amino acids composed of aspartic acid, glutamic acid, and asparagine. Further, a mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) contained in the tobacco-containing segment is 12 to 60.
- the present inventors have found that in a flavor inhaler provided with the filter containing natural fibers, controlling the mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) contained in the tobacco-containing segment within the range of 12 to 60 improved flavor quality.
- the acetate filter can sufficiently remove the causative components evoking a feeling of discomfort that are vapor phase components, however, the filter containing natural fibers cannot sufficiently remove such causative components evoking a feeling of discomfort.
- the aforementioned mass ratio (trisaccharides/tri amino acids) of 12 or more is presumed to increase sweetness and umami taste, alleviating a feeling of discomfort and improving the flavor quality.
- the mass ratio exceeding 60 increases the content ratio of the trisaccharides, evoking a feeling of discomfort derived from the trisaccharides. Therefore, the mass ratio within the range of 12 to 60 is presumed to improve the flavor quality. Furthermore, in the case of the mass ratio within the range of 12 to 60, the Maillard reaction takes place appropriately upon burning or heating the tobacco-containing segment, improving the umami taste, as a result of which the flavor quality is presumably improved.
- the mass ratio of the trisaccharides to the tri amino acids is 12 to 60, preferably 15 to 60, and more preferably 16.5 to 60. It is noted that the content of the tri amino acids and the trisaccharides contained in the tobacco-containing segment is measured by the following method.
- the extract after filtering is directly analyzed by high-performance liquid chromatography as described below for quantitative determination.
- the extract after filtering is directly analyzed by high-performance liquid chromatography as described below for quantitative determination.
- the aforementioned mass ratio can be controlled within the above range by, for example, adjusting a blending ratio of tobacco leaves or adding an additive containing the trisaccharide or the tri amino acid to the tobacco-containing segment.
- the present embodiment can control the above mass ratio and improve the flavor quality by directly utilizing the usual tobacco leaf blending technology and addition technology of flavor and the like, thereby requiring no special manufacturing process or the like and resulting in no effect on product quality.
- types of tobacco leaves and additives that can be selected are diverse, enabling the degree of freedom in designing to be greatly improved.
- the content of the trisaccharides contained in the tobacco-containing segment is preferably 68,800 ppm by mass or more.
- the content of 68,800 ppm by mass or more increases the sweetness.
- the content is more preferably 80,000 to 200,000 ppm by mass and still more preferably 100,000 to 150,000 ppm by mass.
- the content of the tri amino acids contained in the tobacco-containing segment is preferably 2,500 ppm by mass or more.
- the content of 2500 ppm by mass or more appropriately causes the Maillard reaction with the trisaccharides and increases the umami taste.
- the content is more preferably 2,500 to 10,000 ppm by mass and still more preferably 2,500 to 6,000 ppm by mass.
- the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in smoke generated upon burning only the tobacco-containing segment is preferably 0.16 to 0.35, as in the second embodiment described below.
- the mass ratio is more preferably 0.18 to 0.35, and still more preferably 0.20 to 0.34.

- the tobacco-containing segment includes a tubular wrapper and a tobacco filling filled inside the wrapper.
- the first filter segment is also provided with a filter containing natural fibers.
- the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in smoke generated upon burning only the tobacco-containing segment is 0.16 to 0.35.
- the term "upon burning only the tobacco-containing segment” refers to removing the tobacco-containing segment from the flavor inhaler and burning the single tobacco-containing segment.
- the present inventors have found that analysis of smoke generated upon burning only the tobacco-containing segment without passing through the filter segment demonstrated that the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in the smoke being 0.16 to 0.35 improved the flavor quality.
- Controlling the mass ratio of furaneol, which is considered one of the umami taste components, and methyl ethyl ketone, which is considered one of the causative components evoking a feeling of discomfort, within the aforementioned range is presumed to enable an appropriate smoke composition to be achieved for the filtration characteristics of the filter containing natural fibers, thereby enabling the flavor quality to be improved.
- the aforementioned mass ratio (furaneol/methyl ethyl ketone) is 0.16 to 0.35, preferably 0.18 to 0.35, and more preferably 0.20 to 0.34. It is noted that the content of furaneol and methyl ethyl ketone contained in the smoke is measured by the following method. The content is represented as content per crude tar amount (TPM).
- the measurement of the content of furaneol and methyl ethyl ketone is carried out according to the following procedure.
- the tobacco-containing segment is removed from the flavor inhaler, undergoes conditioning under ISO 3402 conditions, and then ignited under ISO 4387 conditions and burned.
- the produced mainstream smoke is passed through a glass fiber filter (Model: Filer 44mm ⁇ , manufactured by Borgwald KC, Inc.) and an impinger with 10mL of methanol collection liquid cooled to -70°C or lower, and then collected. To the impinger solution collected was added a glass fiber filter and they underwent shaking extraction at 180 rpm for 20 minutes.
- the extract obtained is filtered through a syringe filter with a pore diameter of 0.45 ⁇ m (manufactured by Millipore Corporation), and the filtrate is quantitatively analyzed by using the following gas chromatograph-mass spectrometer.
- the mass ratio of furaneol to methyl ethyl ketone is calculated based on the content of each component per crude tar amount (TPM) obtained.
- the crude tar amount (TPM) is measured by the following method.
- the tobacco-containing segment is removed from the flavor inhaler, undergoes conditioning under ISO 3402 conditions, and then ignited under ISO 4387 conditions and burned.
- the crude tar produced by pyrolysis from the tobacco-containing segment is collected to a glass fiber filter (Model: Filer 44mm ⁇ , manufactured by Borgwald KC, Inc.) and a crude tar amount (TPM) is measured from the difference between the mass of the glass fiber filter before collection and that after collection.
- the mass ratio can be controlled within the aforementioned range by controlling, for example, the mass ratio of the trisaccharides to the tri amino acids contained in the tobacco-containing segment (trisaccharides/tri amino acids) to 12 to 60, as in the first embodiment, and controlling the mass ratios of the saccharide other than the trisaccharides (maltose, inositol, or the like) and the amino acid other than the tri amino acids (proline, alanine, threonine, or the like), and the like.

Abstract
Provided is a flavor inhaler that is provided with a filter containing natural fibers and has an improved flavor quality. The flavor inhaler including a tobacco-containing segment including a tubular wrapper and a tobacco filling filled inside the wrapper, and a first filter segment provided with a filter containing natural fibers, in which the tobacco-containing segment contains trisaccharides composed of glucose, fructose, and sucrose and tri amino acids composed of aspartic acid, glutamic acid, and asparagine, and a mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) is 12 to 60.
Description
- The present invention relates to a flavor inhaler.
- As filters for flavor inhalers containing flavor components such as tobacco, acetate filters are usually used, in which cellulose acetate fibers are filled inside a tubular wrapper as filtering materials. However, cellulose acetate fibers are semi-synthetic fibers, and therefore they have low dispersibility and degradability when, for example, the flavor inhaler is disposed of, resulting in a heavy burden on the natural environment. Therefore, from the viewpoint of reducing environmental burden, development of a filter using natural fibers has been desired.
- Filters containing natural fibers include, for example, paper filters that contain paper made of plant pulp as filtering materials. However, the paper filter has different filtration characteristics from acetate filters in terms of smoke components, and the paper filter tends to remove more particle phase components and less vapor phase components, compared to the acetate filters. Due to this filtration characteristic, flavor inhalers provided with paper filters tend to have less umami taste components in the flavor and evoke a feeling of discomfort, thereby desiring the improvement of flavor quality.

Fig. 3] Fig. 3 is an example of the non-combustion-heating-type flavor inhalation system according to the present embodiment, illustrating (a) a state before inserting the non-combustion-heating-type flavor inhaler into the heater, and (b) a state of inserting the non-combustion-heating-type flavor inhaler into the heater and heating it. - The flavor inhaler according to the first embodiment of the present invention is provided with a tobacco-containing segment and a first filter segment. The tobacco-containing segment includes a tubular wrapper and a tobacco filling filled inside the wrapper. Moreover, the first filter segment is also provided with a filter containing natural fibers. Here, the tobacco-containing segment contains trisaccharides composed of glucose, fructose, and sucrose, and tri amino acids composed of aspartic acid, glutamic acid, and asparagine. Further, a mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) contained in the tobacco-containing segment is 12 to 60.
- The present inventors have found that in a flavor inhaler provided with the filter containing natural fibers, controlling the mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) contained in the tobacco-containing segment within the range of 12 to 60 improved flavor quality. As describe above, the acetate filter can sufficiently remove the causative components evoking a feeling of discomfort that are vapor phase components, however, the filter containing natural fibers cannot sufficiently remove such causative components evoking a feeling of discomfort. However, the aforementioned mass ratio (trisaccharides/tri amino acids) of 12 or more is presumed to increase sweetness and umami taste, alleviating a feeling of discomfort and improving the flavor quality. Moreover, the mass ratio exceeding 60 increases the content ratio of the trisaccharides, evoking a feeling of discomfort derived from the trisaccharides. Therefore, the mass ratio within the range of 12 to 60 is presumed to improve the flavor quality. Furthermore, in the case of the mass ratio within the range of 12 to 60, the Maillard reaction takes place appropriately upon burning or heating the tobacco-containing segment, improving the umami taste, as a result of which the flavor quality is presumably improved.
- In the present embodiment, the mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) is 12 to 60, preferably 15 to 60, and more preferably 16.5 to 60. It is noted that the content of the tri amino acids and the trisaccharides contained in the tobacco-containing segment is measured by the following method.
- A powder sample is prepared from the tobacco-containing segment by using an absolute mill (ABS-W: manufactured by Osaka Chemical Ind. Co., Ltd.), and to 1 g of the powder sample is added 40 mL of an extraction solvent (acetonitrile: ultrapure water (produced by Mili-Q) = 1:1,), and the mixture underwent supersonic waves treatment for 30 min to extract saccharides. The extract after filtering is directly analyzed by high-performance liquid chromatography as described below for quantitative determination.

- Column: HPLC NH2 column (Capcell PakNH2 UG80, manufactured by Shiseido Company, Limited.)
- Mobile phase: 75% acetonitrile (NeCN: distilled water = 75:25)
- A powder sample is prepared from the tobacco-containing segment by using an absolute mill (ABS-W: manufactured by Osaka Chemical Ind. Co., Ltd.), and to 1 g of the powder sample is added 20 mL of an extraction solvent (80% methanol (methanol: ultrapure water (produced by MiliQ) = 8:2), and the mixture underwent supersonic waves treatment for 30 min to extract amino acids. The extract after filtering is directly analyzed by high-performance liquid chromatography as described below for quantitative determination.

- Column: Agilent ZORBAX Eclipse AAA
- Mobile phase A: 40 mM phosphate buffer
- Mobile phase B: 45% acetonitrile/45% methanol aqueous solution
- Gradient mode: On
- The aforementioned mass ratio (trisaccharides/tri amino acids) can be controlled within the above range by, for example, adjusting a blending ratio of tobacco leaves or adding an additive containing the trisaccharide or the tri amino acid to the tobacco-containing segment. In such a way, the present embodiment can control the above mass ratio and improve the flavor quality by directly utilizing the usual tobacco leaf blending technology and addition technology of flavor and the like, thereby requiring no special manufacturing process or the like and resulting in no effect on product quality. Further, types of tobacco leaves and additives that can be selected are diverse, enabling the degree of freedom in designing to be greatly improved.
- The content of the trisaccharides contained in the tobacco-containing segment is preferably 68,800 ppm by mass or more. The content of 68,800 ppm by mass or more increases the sweetness. The content is more preferably 80,000 to 200,000 ppm by mass and still more preferably 100,000 to 150,000 ppm by mass.
- The content of the tri amino acids contained in the tobacco-containing segment is preferably 2,500 ppm by mass or more. The content of 2500 ppm by mass or more appropriately causes the Maillard reaction with the trisaccharides and increases the umami taste. The content is more preferably 2,500 to 10,000 ppm by mass and still more preferably 2,500 to 6,000 ppm by mass.
- In the present embodiment as well, the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in smoke generated upon burning only the tobacco-containing segment is preferably 0.16 to 0.35, as in the second embodiment described below. The mass ratio is more preferably 0.18 to 0.35, and still more preferably 0.20 to 0.34.
- The flavor inhaler according to the second embodiment of the present invention is provided with the tobacco-containing segment and the first filter segment. The tobacco-containing segment includes a tubular wrapper and a tobacco filling filled inside the wrapper. Moreover, the first filter segment is also provided with a filter containing natural fibers. Herein, the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in smoke generated upon burning only the tobacco-containing segment is 0.16 to 0.35. Here, the term "upon burning only the tobacco-containing segment" refers to removing the tobacco-containing segment from the flavor inhaler and burning the single tobacco-containing segment.
- The present inventors have found that analysis of smoke generated upon burning only the tobacco-containing segment without passing through the filter segment demonstrated that the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) contained in the smoke being 0.16 to 0.35 improved the flavor quality. Controlling the mass ratio of furaneol, which is considered one of the umami taste components, and methyl ethyl ketone, which is considered one of the causative components evoking a feeling of discomfort, within the aforementioned range is presumed to enable an appropriate smoke composition to be achieved for the filtration characteristics of the filter containing natural fibers, thereby enabling the flavor quality to be improved.
- In the present embodiment, the aforementioned mass ratio (furaneol/methyl ethyl ketone) is 0.16 to 0.35, preferably 0.18 to 0.35, and more preferably 0.20 to 0.34. It is noted that the content of furaneol and methyl ethyl ketone contained in the smoke is measured by the following method. The content is represented as content per crude tar amount (TPM).
- The measurement of the content of furaneol and methyl ethyl ketone is carried out according to the following procedure. The tobacco-containing segment is removed from the flavor inhaler, undergoes conditioning under ISO 3402 conditions, and then ignited under ISO 4387 conditions and burned. The produced mainstream smoke is passed through a glass fiber filter (Model: Filer 44mmφ, manufactured by Borgwald KC, Inc.) and an impinger with 10mL of methanol collection liquid cooled to -70°C or lower, and then collected. To the impinger solution collected was added a glass fiber filter and they underwent shaking extraction at 180 rpm for 20 minutes. The extract obtained is filtered through a syringe filter with a pore diameter of 0.45 µm (manufactured by Millipore Corporation), and the filtrate is quantitatively analyzed by using the following gas chromatograph-mass spectrometer. The mass ratio of furaneol to methyl ethyl ketone is calculated based on the content of each component per crude tar amount (TPM) obtained.
- Analysis equipment: Gas chromatograph-mass spectrometer
- Furaneol measurement (GC 7890B•MS59 77B manufactured by Agilent Technologies Inc. and MPS2•CIS4 (cooling apparatus) manufactured by GESTEL K. K.
- Methyl ethyl ketone measurement (GC 7890B•MS5977B manufactured by Agilent Technologies Inc.)
- The crude tar amount (TPM) is measured by the following method. The tobacco-containing segment is removed from the flavor inhaler, undergoes conditioning under ISO 3402 conditions, and then ignited under ISO 4387 conditions and burned. The crude tar produced by pyrolysis from the tobacco-containing segment is collected to a glass fiber filter (Model: Filer 44mmφ, manufactured by Borgwald KC, Inc.) and a crude tar amount (TPM) is measured from the difference between the mass of the glass fiber filter before collection and that after collection.
- The mass ratio (furaneol/methyl ethyl ketone) can be controlled within the aforementioned range by controlling, for example, the mass ratio of the trisaccharides to the tri amino acids contained in the tobacco-containing segment (trisaccharides/tri amino acids) to 12 to 60, as in the first embodiment, and controlling the mass ratios of the saccharide other than the trisaccharides (maltose, inositol, or the like) and the amino acid other than the tri amino acids (proline, alanine, threonine, or the like), and the like. For example, increasing the value of the mass ratio (trisaccharides/tri amino acids) tends to increase the value of the aforementioned mass ratio (furaneol/methyl ethyl ketone), which enables the adjustment. In the present embodiment, the mass ratio of the trisaccharides (trisaccharides/tri amino acids) preferably stays within the same range as in the first embodiment. Moreover, the content of the trisaccharides and the tri amino acids contained in the tobacco-containing segment preferably stays within the same range as in the first embodiment. Common configuration of the first embodiment and the second embodiment will be described below. It is noted that the embodiments of the present invention including the first embodiment and the second embodiment is referred to as "present embodiment."
- The tobacco-containing segment according to the present embodiment includes a tubular wrapper and a tobacco filling filled inside the wrapper. The tobacco filling contains tobacco and may contain an aerosol-generating substrate, volatile fragrance component, water, and the like. Moreover, the tobacco-containing segment may further contain an additive containing at least one of the trisaccharides or the tri amino acids in order to adjust the mass ratio of the trisaccharides to the tri amino acids to be in the range of the present embodiment. The additive may be contained inside the tobacco filling or may be imparted to the wrapper.
- A size of tobacco contained in the tobacco filling and the preparation method of the tobacco are not particularly limited. For example, dried tobacco leaves may be shredded to a width of 0.8 to 1.2 mm for use. In the case of shredding it to the aforementioned width, the length of the shredding will be approximately 5 to 20 mm. In addition, dried tobacco leaves may be crushed to an average particle size of 20 to 200 µm, homogenized, processed into a sheet, which is then shredded to a width of 0.8 to 1.2 mm for use. In the case of shredding it to the above width, the length of the shredding will be approximately 5 to 20 mm. Furthermore, the sheet as processed above that underwent gather processing without shredding may be used as a filling. A plurality of sheets formed into cylindrical shapes may also be arranged in concentric circles. Various types of tobacco contained in the tobacco filling can be used, even in either case in which dried tobacco leaves are shredded for use, or crushed, homogenized and formed into a sheet. For example, a flue-cured type, burley type, orient type, native type, as well as other Nicotiana tabacum-based varieties or Nicotiana rustica-based varieties, can be blended as appropriate and used so that the mass ratio of the trisaccharides to the tri amino acids stays within the range of the present embodiment. Details on the varieties of the tobacco are disclosed in, for example, "Encyclopedia of Tobacco, Tobacco Research Center, 2009. 3. 31."
- There are several conventional methods for crushing and processing tobacco into homogenized sheets: the first one is a paper sheet made using a papermaking process; the second is a cast sheet made by mixing a suitable solvent such as water to homogenize a product and then casting a thin layer of the homogenized product onto a metal plate or metal plate belt, which is then dried; and the third is a rolled sheet made by extruding a product mixed with a suitable solvent such as water and then homogenized, into sheet form and then molding it into rolled form. Details on the types of aforementioned homogenized sheets are disclosed in, for example, "Encyclopedia of Tobacco, Tobacco Research Center, 2009. 3. 31."
- The filling density of the tobacco filling is not particularly limited, and from the viewpoint of ensuring the performance of the flavor inhaler and imparting a favorable flavor, it is usually 150 mg/cm3 or higher, and preferably 165 mg/cm3 or higher, and is usually 320 mg/cm3 or lower and preferably 300 mg/cm3 or lower. Specifically, the ranges of the content of the tobacco filling contained in the tobacco-containing segment include 408 to 872 mg and preferably 449 to 817 mg per tobacco-containing segment in the case of a tobacco-containing segment with a circumference of 24.5 mm and a length of 57 mm.
- In the case of the flavor inhaler according to the present embodiment being a non-combustion-heating-type flavor inhaler, the tobacco filling can contain an aerosol-generating substrate. The aerosol-generating substrate is a material that can generate an aerosol upon heating. The aerosol-generating substrates are not particularly limited, and include, for example, glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1,3-butanediol, and the like.

- The flavor inhaler according to the present embodiment can be provided with a plurality of filter segments. In this case, at least one of the plurality of filter segments is the first filter segment. Other filter segments other than the first filter segment include, for example, a filter segment filled with synthetic fibers or semi-synthetic fibers such as acetate or a polylactic acid, a filter segment filled with films such as acetate or a polylactic acid, a filter segment with a hollow structure or coaxial structure, a filter segment including a flavor capsule with a core-shell structure in which a liquid flavoring is wrapped by a shell of gelatin, a polysaccharide, a resin, or the like, a filter segment containing a solid adsorbent such as activated carbon, and the like. The flavor inhaler having a plurality of filter segments enables the plurality of filter segments to be arranged adjacent to each other. The plurality of filter segments can be connected to each other by being covered on the periphery thereof by a filter plug wrapper, enabling a multi-filter to be formed.
- The flavor inhaler according to the present embodiment can be a combustion-type flavor inhaler. An example of the combustion-type flavor inhaler is shown in
Fig. 1 . As shown inFig. 1 , a combustion-type flavor inhaler 1 includes a tobacco-containingsegment 2 and afirst filter segment 3 provided adjacent to a tobacco-containingsegment 2. Tobacco-containingsegment 2 includes a tobacco filling 4 and awrapper 5 wrapped around tobacco filling 4. Tobacco-containingsegment 2 andfirst filter segment 3 are connected by atip paper member 6 wound on tobacco-containingsegment 2 andfirst filter segment 3.Tip paper member 6 may have a ventilation hole in a portion of the outer periphery. The number of ventilation holes may be one or plural, and for example, 10 to 40 holes may be formed. In the case of the number of ventilation holes being plural, the ventilation holes can be arranged annularly, for example, in a row on the outer peripheral portion oftip paper member 6. The plurality of ventilation holes can be arranged at substantially constant intervals. The ventilation holes arranged allow air to be drawn intofirst filter segment 3 through the ventilation holes upon inhalation. By diluting mainstream smoke with outside air through the ventilation holes, a product design with a desired tar value can be achieved. Such combustion-type flavor inhalers generally include an inhaler represented by a cigarette. - A user can enjoy flavor of tobacco by igniting the tip of tobacco-containing
segment 2 and sucking the mouthpiece end offirst filter segment 3 with a mouth. Combustion-type flavor inhaler 1 according to the present embodiment, in whichfirst filter segment 3 is provided with a filter containing natural fibers, can achieve a favorable flavor. - The flavor inhaler according to the present embodiment can be a non-combustion-heating-type flavor inhaler. An example of the non-combustion-heating-type flavor inhaler according to the present embodiment is shown in
Fig. 2 . A non-combustion-heating-type flavor inhaler 7 shown inFig. 2 is provided with tobacco-containingsegment 8 and amouthpiece segment 9.Mouthpiece segment 9 is provided with acooling segment 10, acenter hole segment 11, andfirst filter segment 12. Upon inhalation, tobacco-containingsegment 8 is heated, and each component contained in the tobacco filling is vaporized and transferred tomouthpiece segment 9 by inhalation. Then it undergoes inhalation procedure from the end offirst filter segment 12. - Cooling
segment 10 can be configured of atubular member 13.Tubular member 13 can be, for example, a paper tube made of cardboard processed into a cylindrical shape.Tubular member 13 and amouthpiece lining paper 18 to be described below haveperforations 14 penetrating both. The presence ofperforations 14 allows outside air to be introduced intocooling segment 10 upon inhalation. This causes an aerosol vaporization component generated by heating tobacco-containingsegment 8 to contact the outside air and lower the temperature of the aerosol vaporization component, whereby it is liquified and formed into aerosol. The diameter (span length) ofperforation 14 is not particularly limited, and may be, for example, 0.5 to 1.5 mm. The number ofperforations 14 is not particularly limited and can be one, two or more. For example, a plurality ofperforations 14 may be arranged on the circumference ofcooling segment 10. - A
center hole segment 11 can be configured of afilling layer 15 with a hollow portion, aninner plug wrapper 16covering filling layer 15.Center hole segment 11 functions to increase the strength ofmouthpiece segment 9. Fillinglayer 15 can be a rod with an inner diameter of φ5.0 to φ1.0 mm densely filled with, for example, cellulose acetate fibers and cured with a plasticizer containing triacetin added at 6 to 20% by mass relative to the cellulose acetate mass. Fillinglayer 15 has a high fiber filling density, so that air and aerosol flow only in the hollow section upon inhalation, and very little in fillinglayer 15. In a case in which it is desirable to lower the reduction of the aerosol components infirst filter segment 12 by filtration, shortening the length offirst filter segment 12 and replacing it withcenter hole segment 11 are effective to increase the delivery amount of aerosol components. Since fillinglayer 15 insidecenter hole segment 11 is a fiber-filled layer, it is pleasant to touch it from the outside upon use. -
Center hole segment 11 is connected tofirst filter segment 12 by anouter plug wrapper 17.Outer plug wrapper 17 can be, for example, cylindrical paper. In addition, tobacco-containingsegment 8, coolingsegment 10, the connectedcenter hole segment 11 andfirst filter segment 12, are connected by amouthpiece lining paper 18. They can be connected by, for example, coating the inner surface ofmouthpiece lining paper 18 with a glue such as a vinyl acetate-based and then inserting and winding the aforementioned three segments. - The axial length of the non-combustion-heating-type flavor inhaler according to the present embodiment, i.e., the length in the horizontal direction in
Fig. 2 , is not particularly limited, and is preferably 40 to 90 mm, more preferably 50 to 75 mm, and still more preferably 50 to 60 mm. Moreover, the circumference length of the non-combustion-heating-type flavor inhaler is preferably 16 to 25 mm, more preferably 20 to 24 mm, and still more preferably 21 and 23 mm. For example, an aspect of the length of 20 mm of tobacco-containingsegment 8, the length of 20 mm of coolingsegment 10, the length of 8 mm ofcenter hole segment 11, and the length of 7 mm offirst filter segment 12, can be included. These individual segment lengths can be appropriately changed according to suitability for manufacturing, quality requirements, and the like. Furthermore, onlyfirst filter segment 12 may be arranged downstream ofcooling segment 10 withoutcenter hole segment 11. In the non-combustion-heating-type flavor inhaler according to the present embodiment,first filter segment 12 is provided with the filter containing natural fibers, thereby enabling to provide a favorable flavor. - The non-combustion-heating-type flavor inhalation system according to the present embodiment can be provided with the non-combustion-heating-type flavor inhaler according to the present embodiment and a heater that heats the non-combustion-heating-type flavor inhaler. The non-combustion-heating-type flavor inhalation system according to the present embodiment may have other configurations other than the non-combustion-heating-type flavor inhaler according to the present embodiment and the heater described above.
- An example of the non-combustion-heating-type flavor inhalation system according to the present embodiment is shown in
Fig. 3 . The non-combustion-heating-type flavor inhalation system shown inFig. 3 has a non-combustion-heating-type flavor inhaler 7 according to the present embodiment and aheater 19 that heats the tobacco-containing segment of non-combustion-heating-type flavor inhaler 7 from the outside.Fig. 3 (a) shows the state of non-combustion-heating-type flavor inhaler 7 before inserting it intoheater 19, andFig. 3 (b) shows the state of non-combustion-heating-type flavor inhaler 7 that is inserted intoheater 19 and heated.Heater 19 shown inFig. 3 is configured of abody 20, aheating body 21, ametal tube 22, a battery unit 23, and acontrol unit 24.Body 20 has a cylindrical recessedportion 25, andheating body 21 andmetal tube 22 are arranged at the position of the inner side of recessedportion 25, corresponding to the tobacco-containing segment of non-combustion-heating-type flavor inhaler 7 that is to be inserted into recessedportion 25.Heating body 21 can be an electric resistance heater and is heated by electric power supplied from a battery unit 23 under the direction of acontrol unit 24 that controls temperature. The heat emitted fromheating body 21 is transferred to the tobacco-containing segment of the non-combustion-heating-type flavor inhaler 7 throughmetal tube 22 with high thermal conductivity. -
Fig. 3 (b) is schematically illustrated, however, there is a gap between the outer circumference of non-combustion-heating-type flavor inhaler 7 and the inner circumference ofmetal tube 22. Actually the gap is desirably not present between the outer circumference of non-combustion-heating-type flavor inhaler 7 and the inner circumference ofmetal tube 22 for the purpose of transferring efficient heat. Moreover,heater 19 heats the tobacco-containing segment of non-combustion-heating-type flavor inhaler 7 from outside, however it may also be a heater heated from inside. In a case in whichheater 19 is heated from inside, a rigid platy, bladed, or columnar heater instead ofmetal tube 22 is preferably used. The heaters related thereto include, for example, a ceramic heater with molybdenum or tungsten on a ceramic substrate. - A heating temperature by the heater is not particularly limited, and is preferably 400°C or lower, more preferably 150°C or higher and 400°C or lower, and still more preferably 200°C or higher and 350°C or lower. It is noted that the heating temperature indicates the heating body temperature of the heater.

- A flavor inhaler was fabricated in the same manner as in Example 1 except that an acetate filter (circumference of 24.1 mm and length of 108 mm, fabricated by a filter manufacturing machine usually used) was used as a first filter segment in Example 1.
- For each of the flavor inhalers fabricated, the content of the tri amino acids and trisaccharides contained in the tobacco-containing segment was measured by the method described above, and the mass ratio of the trisaccharides to the tri amino acids (trisaccharides/tri amino acids) was calculated. The results are shown in Table 1.
- For each of the flavor inhalers fabricated, the content of furaneol and methyl ethyl ketone contained in smoke generated upon burning only the tobacco-containing segment was measured by the method described above, and the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) was calculated. The results are shown in Table 2. It is noted that the content is represented as content per unit of crude tar amount (TPM).
- Six panelists (panelists a to f) evaluated the flavor quality for each flavor inhaler fabricated. The evaluations were conducted on four items: "umami taste," "sweetness," "feeling of discomfort," and "overall evaluation." For "umami taste," "sweetness," and "feeling of discomfort," scores for "umami taste," "sweetness," and "feeling of discomfort" upon using the flavor inhaler in Reference Example 1 were set to
scale 5, and a scale of 1 (little umami taste or sweetness, week feeling of discomfort) to 10 (much umami taste or sweetness, strong feeling of discomfort) are scored for Examples 1 to 7 and Comparison Example 1. The results are shown in Table 3 and Table 4. Here, Table 3 shows the individual scores of each panelist and average values thereof, and Table 4 shows the average values. Moreover, for the "overall evaluation," "A" is scored for the overall flavor quality that is the same or higher, "B" is scored for the overall flavor quality that is slightly lower but having an improvement effect, and "C" is scored for the overall flavor quality that is significantly lower, compared to the overall flavor quality upon using the flavor inhaler of Reference Example 1, and the overall evaluation was evaluated by the consensus of all the panelists. The results are shown in Table 4. It is noted that the six panelists (panelists a to f) have been well trained using several samples with different concentrations, and it has been confirmed that their scores and evaluation thresholds for "umami taste," "sweetness," "feeling of discomfort," and "flavor quality (overall evaluation)" are equal and standardized among the panelists.[Table 1] Trisaccharides [unit: ug/g] Tri amino acids [unit: ug/g] Mass ratio Trisaccharides/ Tri amino acids Fructose Glucose Sucrose Trisaccharides Aspartic acid Glutamic acid Asparagine Tri amino acids Comparative Example 1 32600 23300 31400 87300 2179 750 4479 7408 11.8 Example 1 36300 26800 8000 71100 949 656 3227 4832 14.7 Example 2 35100 26700 7000 68800 962 555 2754 4271 16.1 Example 3 40100 33400 12200 85700 1528 776 2789 5093 16.8 Example 4 48800 41000 11500 101300 1472 621 2337 4430 22. 9 Example 5 53700 48700 20000 122400 557 538 3597 4692 26.1 Example 6 56500 51600 19700 127800 568 508 2714 3790 33.7 Example 7 68400 61800 19400 149600 440 378 1773 2591 57.7 Reference Example 1 36300 26800 8000 71100 949 656 3227 4832 14.7 [Table 2] Smoke component [unit: ug/g] B/A Methyl ethyl ketone (A) Furaneol (B) Comparative Example 1 3.027 0.463 0.153 Example 1 2.574 0.430 0.167 Example 2 2.467 0.475 0.193 Example 3 2.471 0.512 0.207 Example 4 2.492 0.603 0.242 Example 5 2.466 0.610 0.247 Example 6 2.383 0.639 0.268 Example 7 2.320 0.780 0.336 Reference Example 1 2.574 0.430 0.167 [Table 4] Umami taste (X) Sweetness (Y) Feeling of discomfort (Z) (X+Y)/Z Overall evaluation Comparative Example 1 3.2 2.5 7.2 0.8 C Example 1 3.3 4.3 8.0 1.0 B Example 2 4.5 5.0 7.2 1.3 A Example 3 5.7 5.3 6.7 1.7 A Example 4 6.2 6.3 6.0 2.1 A Example 5 4.8 5.7 6.7 1.6 A Example 6 5.7 5.7 6.2 1.8 A Example 7 6.2 6.5 5.5 2.3 A Reference Example 1 5.0 5.0 5.0 2.0 - -
