Description

The present invention relates to flavor inhalers.

BACKGROUND ART As a filter for a flavor inhaler containing flavor components such as tobacco, an acetate filter in which a cylindrical wrapper is filled with cellulose acetate fibers as a filtering material is usually used. However, since cellulose acetate fiber is a semisynthetic fiber, it has low dispersibility and degradability when, for example, the flavor inhaler is discarded, and has a large impact on the natural environment. Therefore, from the viewpoint of reducing the burden on the environment, the development of filters using natural fibers is desired.

Filters containing natural fibers include, for example, paper filters containing paper made of vegetable pulp as a filtering material. However, paper filters differ from acetate filters in filtering smoke components, and paper filters tend to remove more particulate phase components and less vapor phase components than acetate filters. Because of the filtration characteristics, flavor inhalers equipped with paper filters tend to have less umami components in the flavor, making them more unpleasant, and an improvement in flavor quality is desired.

As a method for approximating the filtration characteristics of the paper filter to that of the acetate filter, for example, Patent Documents 1 and 2 disclose a method of adding additives such as polyalkylene glycol and triacetin to the paper filter.

On the other hand, in Patent Document 3, for the purpose of producing a sheet tobacco that generates a small amount of formaldehyde, an extract is obtained from tobacco raw materials having a predetermined ratio of sugar content and glutamine content, and the extract is extracted. A method of applying the subsequent residue back to the formed sheet is disclosed.

However, the method of adding an additive to the filter as disclosed in Patent Documents 1 and 2 is complicated in the manufacturing process and its management. Dissolution may occur, reducing product quality. Therefore, this method requires a high degree of skill in controlling the physical properties of the additive and addition technology, and is not practical. Moreover, Patent Document 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 having a filter containing natural fibers and having improved flavor quality.

[First embodiment]
A flavor inhaler according to a first embodiment of the present invention comprises a tobacco-containing segment and a first filter segment. The tobacco-containing segment includes a tubular wrapper and a tobacco filling filled in the wrapper. Also, the first filter segment comprises a filter comprising natural fibers. Here, the tobacco-containing segment comprises a trisaccharide consisting of glucose, fructose and sucrose and a triamino acid consisting of aspartic acid, glutamic acid and asparagine. Further, the mass ratio of the trisaccharide to the triamino acid (trisaccharide/triamino acid) contained in the tobacco-containing segment is 12-60.

The present inventors have found that in a flavor inhaler equipped with a filter containing natural fibers, the mass ratio of the trisaccharide to the triamino acid (trisaccharide/triamino acid) contained in the tobacco-containing segment is within the range of 12 to 60. It has been found that the control improves the flavor quality. As described above, the acetate filter can sufficiently remove the discomfort-causing component, which is the vapor phase component, but the filter containing natural fibers cannot sufficiently remove the discomfort-causing component. However, by setting the mass ratio (trisaccharide/triamino acid) to 12 or more, it is presumed that the sweetness and umami are increased, and the unpleasant feeling can be covered, thereby improving the flavor quality. On the other hand, when the mass ratio exceeds 60, the content ratio of the trisaccharide becomes high, and discomfort derived from the trisaccharide is felt. Therefore, it is presumed that the flavor quality is improved when the mass ratio is in the range of 12 to 60. Furthermore, when the mass ratio is in the range of 12 to 60, the Maillard reaction occurs appropriately when the tobacco-containing segment is burned or heated, and the umami is improved, so it is speculated that the flavor quality is improved as a result. be.

In this embodiment, the mass ratio of the trisaccharide to the triamino acid (trisaccharide/triamino acid) is 12-60, preferably 15-60, more preferably 16.5-60. The contents of the three amino acids and the trisaccharide contained in the tobacco-containing segment are measured by the following methods.

<Quantification of trisaccharide content>
Using an absolute mill (ABS-W: manufactured by Osaka Chemical Co., Ltd.), a powder sample was prepared from the tobacco-containing segment, and 40 mL of an extraction solvent (acetonitrile: ultrapure water (manufactured by MiliQ) was added to 1 g of this powder sample. = 1:1) is added, and ultrasonication is performed for 30 minutes to extract sugars. After filtration, the extract is directly analyzed and quantified by the following high performance liquid chromatography.
・Analytical equipment: high-performance liquid chromatography RI detector (JASCO)
Column: HPLC NH2 column (Capcell PakNH2 UG80, Shiseido)
Mobile phase: 75% acetonitrile (NeCN: distilled water = 75:25)

<Quantitative determination of tri-amino acid content>
A powder sample was prepared from the tobacco-containing segment using an absolute mill (ABS-W: manufactured by Osaka Chemical Co., Ltd.), and 20 mL of an extraction solvent (80% methanol (methanol: ultrapure water (MiliQ )=8:2)) is added, and ultrasonic treatment is performed for 30 minutes to extract amino acids. After filtration, the extract is directly analyzed and quantified by the following high performance liquid chromatography.
- Analytical instrument: high-performance liquid chromatography diode array (DAD) detector (Agilent 1290)
Column: Agilent ZORBAX Eclipse AAA
Mobile phase A: 40 mM phosphate buffer Mobile phase B: 45% acetonitrile/45% methanol aqueous solution Gradient: Yes

The mass ratio (trisaccharide/triamino acid) is controlled within the above range, for example, by adjusting the blending ratio of tobacco leaves, adding an additive containing the trisaccharide or the triamino acid to the tobacco-containing segment, or the like. can be done. As described above, in the present embodiment, the mass ratio can be controlled and the flavor quality can be improved by using the ordinary tobacco leaf blending technique and the technique of adding flavorings and the like. No impact on quality. In addition, a wide variety of tobacco leaves and additives can be selected, greatly improving the degree of freedom in design.

The content of the trisaccharide contained in the tobacco-containing segment is preferably 68800 ppm by mass or more. Sweetness increases when the content is 68800 mass ppm or more. The content is more preferably 80000 to 200000 ppm by mass, more preferably 100000 to 150000 ppm by mass.

The content of the three amino acids contained in the tobacco-containing segment is preferably 2500 ppm by mass or more. When the content is 2500 ppm by mass or more, the Maillard reaction with the trisaccharide occurs appropriately and the umami is increased. The content is more preferably 2,500 to 10,000 ppm by mass, even more preferably 2,500 to 6,000 ppm by mass.

In this embodiment, as in the second embodiment described later, the mass ratio of furaneol to methyl ethyl ketone contained in the smoke generated when only the tobacco-containing segment is burned (furaneol/methyl ethyl ketone) is 0.16. ~0.35 is preferred. The mass ratio is more preferably 0.18 to 0.35, still more preferably 0.20 to 0.34.

[Second embodiment]
A flavor inhaler according to a second embodiment of the present invention comprises a tobacco-containing segment and a first filter segment. The tobacco-containing segment includes a tubular wrapper and a tobacco filling filled in the wrapper. Also, the first filter segment comprises a filter comprising natural fibers. Here, the mass ratio (furaneol/methyl ethyl ketone) of furaneol to methyl ethyl ketone contained in the smoke generated when only the tobacco-containing segment is burned is 0.16 to 0.35. Note that "when only the tobacco-containing segment is burned" means removing the tobacco-containing segment from the flavor inhaler and burning the tobacco-containing segment alone.

The present inventors have found that when the smoke generated when only the tobacco-containing segment is burned is analyzed as it is without passing through the filter segment, the mass ratio of furaneol to methyl ethyl ketone contained in the smoke (furaneol/methyl ethyl ketone) is 0.16 to 0.35, the flavor quality is improved. By controlling the mass ratio of furaneol, which is considered to be one of the umami components, and methyl ethyl ketone, which is considered to be one of the components that cause discomfort, within the above range, a smoke composition suitable for the filtration characteristics of filters containing natural fibers can be obtained. It is speculated that this can be achieved, resulting in improved flavor quality.

In the present embodiment, the mass ratio (furaneol/methyl ethyl ketone) is 0.16 to 0.35, preferably 0.18 to 0.35, more preferably 0.20 to 0.34. The contents of furaneol and methyl ethyl ketone contained in the smoke are measured by the following method. The content is shown as a content equivalent to crude tar content (TPM).

<Measurement of Furaneol and Methyl Ethyl Ketone Contents and Crude Tar Amount (TPM)>
The contents of furaneol and methyl ethyl ketone are measured according to the following procedure. A tobacco-containing segment is removed from the flavor inhaler and after conditioning the tobacco-containing segment under ISO 3402 conditions, it is ignited and burned under ISO 4387 conditions. The generated mainstream smoke is collected by passing it through a glass fiber filter (BORGWALDT, model: Filer 44 mmΦ) and an impinger containing 10 mL of methanol collecting liquid cooled to -70°C or less. A glass fiber filter is added to the collected impinger solution, and extracted by shaking at 180 rpm for 20 minutes. After filtering the resulting extract through a syringe filter (Millipore) having a pore size of 0.45 μm, the filtrate is subjected to quantitative analysis 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 equivalent to the crude tar amount (TPM) obtained.
Analysis equipment: Gas chromatograph mass spectrometer Furaneol measurement (Agilent GC7890B/MS5977B, GESTEL MPS2/cooling device CIS4)
Methyl ethyl ketone measurement (Agilent GC7890B/MS5977B)

The amount of crude tar (TPM) is measured by the following method. A tobacco-containing segment is removed from the flavor inhaler and after conditioning the tobacco-containing segment under ISO 3402 conditions, it is ignited and burned under ISO 4387 conditions. Crude tar generated by pyrolysis from tobacco-containing segments is collected in a glass fiber filter (BORGWALDT, model: Filer 44 mmΦ), and the amount of crude tar (TPM) is measured from the difference in mass of the glass fiber filter before and after collection.

The mass ratio (furaneol/methyl ethyl ketone) is, for example, the mass ratio of the trisaccharide to the three amino acids contained in the tobacco-containing segment (trisaccharide/triamino acid) in the range of 12 to 60 as in the first embodiment. Control within the above range by a method such as controlling the mass ratio of sugars other than the trisaccharide (maltose, inositol, etc.) and amino acids other than the triamino acids (proline, alanine, threonine, etc.) can be done. For example, increasing the value of the mass ratio (trisaccharide/triamino acid) tends to increase the value of the mass ratio (furaneol/methyl ethyl ketone), which can be adjusted. In this embodiment, the mass ratio of the trisaccharide (trisaccharide/triamino acid) is preferably within the same range as in the first embodiment. Moreover, the content of the trisaccharide and the triamino acid contained in the tobacco-containing segment is preferably within the same range as in the first embodiment.

Reducing the length of the first filter segment 12 and replacing it with the center hole segment 11 increases the delivery amount of the aerosol component when it is desired to reduce the reduction due to filtration of the aerosol component in the first filter segment 12. effective for Since the filling layer 15 inside the center hole segment 11 is a fiber filling layer, the feeling of touch from the outside during use is good.

The center hole segment 11 and the first filter segment 12 are connected by an outer plug wrapper 17 . The outer plug wrapper 17 can be, for example, a cylinder of paper. The tobacco-containing segment 8 , cooling segment 10 , connected center hole segment 11 and first filter segment 12 are connected by mouthpiece lining paper 18 . These connections can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 18, inserting the three segments, and winding them.

The axial direction of the non-combustion heating type flavor inhaler according to this embodiment, that is, the horizontal length in FIG. 2 is not particularly limited, but is preferably 40 to 90 mm, more preferably 50 to 75 mm, More preferably, it is 50-60 mm. The length of the circumference of the non-combustion heating flavor inhaler is preferably 16 to 25 mm, more preferably 20 to 24 mm, even more preferably 21 to 23 mm. For example, the length of the tobacco-containing segment 8 is 20 mm, the length of the cooling segment 10 is 20 mm, the length of the center hole segment 11 is 8 mm, and the length of the first filter segment 12 is 7 mm. . These individual segment lengths can be changed as appropriate according to manufacturability, required quality, and the like. Furthermore, only the first filter segment 12 may be arranged downstream of the cooling segment 10 without using the center hole segment 11 . In the non-combustion-heating flavor inhaler according to this embodiment, the first filter segment 12 is equipped with a filter containing natural fibers, and a good flavor can be realized.

[Measurement, Evaluation]
(1) Measurement of mass ratio of trisaccharide to triamino acid (trisaccharide/triamino acid) For each flavor inhaler produced, the content of triamino acids and trisaccharides contained in the tobacco-containing segment was measured by the method described above, The mass ratio of trisaccharide to triamino acid (trisaccharide/triamino acid) was calculated. Table 1 shows the results.

(2) Measurement of mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) For each flavor inhaler prepared, the content of furaneol and methyl ethyl ketone contained in the smoke generated when only the tobacco-containing segment was burned by the above method. The amount was measured and the mass ratio of furaneol to methyl ethyl ketone (furaneol/methyl ethyl ketone) was calculated. Table 2 shows the results. The content is a value shown as a content equivalent to the amount of crude tar (TPM).

(3) Flavor quality evaluation Six panelists (panelists a to f) evaluated the flavor quality of each flavor inhaler produced. Four items of "umami", "sweetness", "discomfort" and "comprehensive evaluation" were evaluated. Regarding "umami", "sweetness" and "discomfort", the scores of "umami", "sweetness" and "discomfort" when using the flavor inhaler of Reference Example 1 were set to 5, and Examples 1 to 7 were evaluated. And the flavor inhaler of Comparative Example 1 was evaluated on a scale of 1 (little umami or sweetness, weak discomfort) to 10 (high umami or sweetness, strong discomfort). Tables 3 and 4 show the results. Table 3 shows individual scores of each panelist and their average values, and Table 4 shows the average values. In addition, for the "comprehensive evaluation", compared with the overall flavor quality when using the flavor inhaler of Reference Example 1, "A" when the overall flavor quality is equal to or higher than the overall flavor quality. All the panelists agreed on the evaluation, with "B" indicating an improvement effect although the flavor quality was slightly reduced, and "C" when the overall flavor quality was greatly reduced. Table 4 shows the results. The six panelists (panelists a to f) were sufficiently trained using several types of samples with different concentrations. It has been confirmed that the scores and evaluation thresholds for "comprehensive evaluation)" are the same, and that they are standardized among the panelists.
