  Hereinafter, embodiments of the present invention will be described in detail.

  The cut piece of the fragrance-containing sheet of the present invention is cut out from the fragrance-containing sheet. The perfume-containing sheet is formed by dispersing a perfume such as menthol in a non-volatile matrix such as a polysaccharide. Such a fragrance | flavor containing sheet | seat is described in international publication WO2009-142159, for example. More specifically, the fragrance-containing sheet is one in which the fragrance is dispersed in a matrix made of a polysaccharide gel. Polysaccharides include carrageenan, agar, gellan gum, tamarind gum, psyllium seed gum or konjac glucomannan alone, or carrageenan, locust bean gum, guar gum, agar, xanthan gum, gellan gum, tamarind gum, tara gum, konjac glucomannan, starch, A combination of two or more polysaccharides selected from the group consisting of cassia gum and psyllium seed gum can be exemplified. Since such a polysaccharide can be gelled by cooling, it is not necessary to add a gelling agent such as a metal chloride. Examples of the fragrances include lipophilic fragrances such as l-menthol and mint oil.

  Such a fragrance-containing sheet is obtained by mixing a polysaccharide and water, heating to obtain an aqueous solution of the polysaccharide, adding a fragrance and preferably an emulsifier to the aqueous solution, stirring to emulsify the fragrance, The obtained emulsion can be cast on a substrate and dried by heating. As the emulsifier, lecithin, sugar ester and the like can be used. Heat drying can be performed at 70 to 200 ° C. In the perfume-containing sheet thus obtained, the perfume is dispersed as particles in the non-volatile matrix. Such a fragrance-containing sheet can contain a fragrance in an amount of 18% by weight or more, preferably 60% by weight or more. Usually, a fragrance | flavor containing sheet | seat contains a fragrance | flavor in the ratio of 65 weight% or less.

  A cut piece is cut out from the flavor-containing sheet. The shape of the cut piece is a hexahedron, but is preferably a rectangular parallelepiped, for example, a regular quadrangular prism, and more preferably a cube.

  Here, regarding the shape of the cut piece, the short side is x, the long side is y, and the thickness is t. The short side and long side in the present invention are defined as a rectangular short side and long side formed by projecting a hexahedron in the thickness direction.

  At this time, the ratio r of the long side / short side, the area A of the cut surface, the volume V of the cut piece, and the ratio α of the area / volume of the cut surface are expressed by the following equations. In addition, the area A of a cut surface means the sum total of four cut surfaces of the cut piece produced when a fragrance | flavor containing sheet | seat is cut | judged vertically and horizontally along the thickness direction.

Long side / short side ratio r r = y / x (when y ≧ x) (1)
Area A A = 2xt + 2yt of the cut surface (2)
Volume V V = xyt of the cut piece (3)
Cut area / volume ratio α α = (2xt + 2yt) / xyt
= 2 (x + y) / xy (4)
Making the area / volume ratio α of the cut surface below a certain value is expressed by the following equation.
α ≧ 2 (x + y) / xy (4 ′)
α ≧ 2 / x + 2 / y (4 ″)
Substituting equation (4 ″) into equation (1) to obtain the relationship between y, α, and r yields the following equation.
r ≦ (αy−2) / 2 (5)
In the present invention, the ratio of the area of the cut surface to the volume of the cut piece is 3.0 or less, the ratio of the length of the long side to the length of the short side is 10 or less, and the length of the long side Is less than the diameter of the cigarette rod to be manufactured. More preferably, in the hexahedron-shaped cut piece, the ratio of the area of the cut surface to the volume thereof is 2.0 or less, the ratio of the length of the long side to the length of the short side is 5 or less, and the length The length of the side is ½ or less of the diameter of the cigarette rod to be manufactured. Usually, when the shape of the cut piece is a quadrangular prism, the short side is 1.0 mm to 2.0 mm.

  The cut piece of the fragrance-containing sheet obtained as described above is mixed with tobacco cut, and the mixture is wound with cigarette wrapping paper to obtain a cigarette rod. Usually, the diameter of a cigarette rod is 3 mm-10 mm.

  EXAMPLES Hereinafter, although an Example demonstrates this invention, this invention is not limited by these Examples.

Example 1
A total of 3680 parts by weight of polysaccharides (gellan gum and tamarind gum) were added to 80000 parts by weight of water, and the mixture was sufficiently stirred at 80 ° C. to dissolve the polysaccharides. An aqueous emulsifier solution in which 18400 parts by weight of a fragrance (1-menthol) and 74 parts by weight of an emulsifier (lecithin) are dissolved in 1398 parts by weight of water is added to the aqueous solution of the polysaccharide, and the resulting mixture is sufficiently emulsified by a homogenizer. It was. This emulsified slurry was cast into a sheet on a substrate and dried at 70 ° C. The thickness of the flavor-containing sheet after drying was 0.1 mm. This fragrance | flavor containing sheet | seat was cut | judged to 1 mm x 10 mm, the cut piece was produced, and 3 weight% was mixed with the tobacco cut. The mixture was wound with cigarette wrapping paper to obtain a cigarette rod (Example 1).

  On the other hand, l-menthol was dissolved in a solvent, the solution was sprayed on tobacco and dried, and then wrapped with cigarette paper as described above to obtain a cigarette rod (Comparative Example 1).

  The perfume residual rate after storing the cigarette rod obtained above in a thermostatic chamber at a temperature of 50 ° C. for a predetermined period (measured amount is 100%) was measured as follows. The results are shown in Table 1 below.

<Measurement of perfume residual rate>
Measurement of menthol content of menthol-containing sheet The menthol content of the menthol-containing sheet was measured by GC-FID as follows.

  First, 0.1 g of tobacco cut mixed with a menthol-containing sheet was weighed, and 10 mL of methanol (reagent grade or equivalent or higher) was exposed to the atmosphere to eliminate the effects of moisture absorption in the air. Was dispensed in a 50 mL sealed container (screw tube) and shaken (200 rpm) for 40 minutes. After standing overnight, shaking (200 rpm) was again performed for 40 minutes, and the supernatant after standing was used as a measurement solution (diluted with × 10 methanol for GC measurement here).

  The measurement solution was subjected to the following GC-FID and quantified by a calibration curve method.

GC-FID; Agilent 6890N gas chromatograph column; DB-WAX 30 m × 530 μm × 1 μm
Constant pressure mode 5.5 psi (speed: 50 cm / sec)
Injection; 1.0 μL
Inlet; Splitless mode 250 ° C 5.5 psi
Oven: 80 ° C. → (10 ° C./min)→170° C. (retention 6.0 minutes) [maximum 220 ° C.]
Detector: FID detector 250 ° C. (H ₂ ; 40 mL / min, air; 450 mL / min)
Signal rate: 20Hz

  As apparent from Table 1, the cut pieces of the fragrance-containing sheet have a much higher fragrance residual ratio than when the fragrance is added directly to the tobacco cut.

Example 2
To 70000 parts by weight of water, 5200 parts by weight of polysaccharides (gellan gum and tamarind gum) were added and sufficiently stirred at 80 ° C. to dissolve the polysaccharides. An aqueous emulsifier solution in which 13000 parts by weight of 1-menthol, 455 parts by weight of colorants (caramel pigment and cocoa powder), and 105 parts by weight of an emulsifier (lecithin) were dissolved in 1995 parts by weight of water was added to this polysaccharide aqueous solution. The resulting mixture was sufficiently emulsified with a homogenizer. The obtained emulsified slurry was cast on a substrate in a sheet form and dried at 70 ° C. The thickness of the flavor-containing sheet after drying was 0.1 mm.

  This fragrance | flavor containing sheet | seat was cut | judged to the square pillar shape of various sizes, and the cut piece was produced. The size of the cut piece produced at this time is as follows.

Cutting piece A 1 mm short side, 10 mm long side, long side / short side ratio 10
Cut piece B 1 mm short side, 5 mm long side, long side / short side ratio 5
Cut piece C 2 mm short side, 3 mm long side, long side / short side ratio 1.5
Each piece was left in a thermostatic bath at a temperature of 50 ° C. for accelerating the volatilization of the fragrance for 1 hour, and the weight reduction rate of the fragrance was measured. The relationship between this reduction rate and the cross-sectional area / volume ratio of the cut piece is shown in FIG. As is clear from the results shown in FIG. 1, in order to suppress the volatilization of the fragrance, the cross-sectional area per volume of the cut piece may be reduced. If the weight reduction rate is 30% or less under the acceleration conditions, the rate of occurrence of problems in appearance of cigarettes (generation of spots on the wrapping paper) is reduced as the fragrance concentration in the cigarette rod. Therefore, in consideration of adaptation to cigarettes, the cross-sectional area / volume of the cut piece is 3 or less, preferably 2 or less where the weight reduction rate of the fragrance is 20% or less.

After measuring the average particle size of the cut pieces A, B and C whose weight reduction rate was 30% or less, each was put in a small mill (trade name: Labo Mill Surplus), and the average particle after grinding for 5 seconds While measuring the diameter, put the crushed sample into a cylindrical container with an inner diameter of 60 mm, and apply a load of 3.0 kg from above, and then the bulge (after crushing) (1 gram of cut piece when the above load is applied) The average particle size distribution is shown in Fig. 2 to Fig. 4. Fig. 2 shows the result for the cut piece A, Fig. 3 shows the result for the cut piece B, and Fig. 4 shows the result for the cut piece C. 2 to 4, the line a indicates the particle size before crushing, the line b indicates the particle size after crushing, and the average particle size of the cut pieces A to B before and after crushing is expanded. The results are shown in Table 2.

  From the results shown in FIGS. 2 to 4 and Table 2, it was confirmed that as the long side / short side ratio of the cut piece approached 1, it was not affected by crushing. Therefore, in order to suppress / control the volatilization of the fragrance from the cut piece, the shape of the cut piece is first defined based on the cross-sectional area / volume ratio, and then the cross-sectional area at the time of cutting is defined, and then the long side / short side ratio It is realized by reducing the generation of the crushing cross section by making it smaller. In addition, when cigarettes are produced with the current cigarette hoisting machine, tobacco engravings containing cut pieces of perfume-containing sheets are adsorbed and conveyed by the adsorption band of the cigarette hoisting machine, but the cut pieces are perpendicular to the conveying direction. Even when adsorbed on the substrate, it is preferable that it can pass without being bent in a later step. Therefore, assuming that the cut piece is placed at the center of the cigarette winding, the long side of the cut surface of the cut piece is preferably less than the diameter of the cigarette rod in order to prevent crushing of the cut piece during cigarette winding. become.

  Actually, the cut piece A and the cut piece C were mixed with 5% of cigarettes and wound on a cigarette rod having a peripheral length of 25.2 mm, and then the cigarette rod was cut and all the cut pieces were collected. It was confirmed that very few pieces were crushed.
