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

The cut pieces of the fragrance-containing sheet of the present invention are cut out from the flavour-containing flakes. Fragrance-containing flakes are perfumes such as menthol dispersed in a non-volatile matrix such as a polysaccharide. Such a flavour-containing flake is described, for example, in International Publication WO 2009-142159. In more detail, the flavour-containing flakes are those which disperse the perfume in a matrix containing the colloid of the polysaccharide. Polysaccharides Carrageenan, cold weather, gellan gum, tamarind gum, psyllium seed gum or konjac glucomannan alone; From carrageenan, locust bean gum, guar gum, cold weather, xanthan gum, yam gum, tamarind gum, tara gum, glutinous nectar A combination of two or more polysaccharides is selected from the group consisting of polysaccharides, starch, cassia gum and psyllium seed gum. Since the polysaccharide can be gelled by cooling, it is not necessary to add a gelling agent such as a metal chloride. The fragrance may, for example, be a lipophilic fragrance such as 1-menthol, peppermint oil or the like.

Such a flavor-containing flake may be obtained by mixing a polysaccharide and water, and heating to obtain an aqueous solution of a polysaccharide, adding a perfume and a preferred emulsifier to the aqueous solution, stirring the mixture to emulsify the fragrance, and pouring the obtained emulsion ( Casting) is obtained by drying on a substrate and heating. As the emulsifier, lecithin, sugar ester or the like can be used. Heating and drying can be carried out at 70 ° C to 200 ° C. In the thus obtained fragrance-containing sheet, the fragrance is dispersed as a particle in a nonvolatile matrix. The flavor-containing flakes may contain 18% by weight or more of perfume, preferably 60% by weight or more. Usually, the flavor-containing flakes contain the perfume in a proportion of 65% by weight or less.

The cut piece was cut out from the flavor-containing sheet. The shape of the cut piece is a hexahedron, but it is preferably a rectangular parallelepiped such as a regular square column, 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 the long side in the present invention are defined as short sides and long sides of a quadrangle 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 area/volume ratio α of the cut surface are expressed by the following mathematical expressions. In addition, the area A of the cut surface indicates the total of the four cut surfaces of the cut piece which are produced when the fragrance-containing sheet is cut vertically and horizontally in the thickness direction.

Long side/short side ratio r r=y/x (y≧x) (1)

Area of the cut surface A A=2xt+2yt (2)

The volume of the cut piece V V=xyt (3)

The area/volume ratio of the cut surface α α=2(2xt+2yt)/xyt=2(x+y)/xy (4)

The following formula shows that the ratio α of the area/volume of the cut surface is a specific value or less.

≧≧(x+y)/xy (4’)

≧2/x+2/y (4")

Substituting the formula (4") into the formula (1) and obtaining the relationship of y, α, and r gives the following formula.

R≦(α y-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, and 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 length of the manufactured cigarette rod. diameter. More preferably, the ratio of the area of the cut surface of the cut piece of the hexahedron shape to the volume of the cut piece is 2.0 or less, and the ratio of the length of the long side to the length of the short side is 5 or less, and the long side is The length is 1/2 or less of the diameter of the manufactured tobacco rod. When the shape of the cut piece is generally a square column, the short side is 1.0 mm to 2.0 mm.

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

(Example)

The invention is illustrated by the following examples, but the invention is not limited to the examples.

Example 1

A total of 3680 parts by weight of a polysaccharide (barlan gum and tamarind gum) was added to 80,000 parts by weight of water, and the polysaccharide was sufficiently stirred and dissolved at 80 °C. 18400 parts by weight of a fragrance (1-menthol), and 74 parts by weight of an emulsifier (lecithin) dissolved in 1398 parts by weight of an aqueous emulsifier solution were added to the aqueous solution of the polysaccharide, and the mixture was sufficiently emulsified by a homogenizer. . The emulsified slurry was cast in a sheet form on a substrate and dried at 70 °C. The dried flavour-containing flakes had a thickness of 0.1 mm. The flavor-containing sheet was cut into 1 mm × 10 mm to prepare a cut piece, and 3% by weight was mixed in the tobacco yarn. The mixture was wrapped in a cigarette paper to obtain a cigarette rod (Example 1).

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

After the cigarette rod obtained above was stored in a thermostat at a temperature of 50 ° C for a specific period of time, the residual rate of the fragrance was measured in the following manner (in an amount of 100%). The results are shown in Table 1 below.

<Measurement of residual rate of spices>

Determination of menthol content of menthol-containing flakes

The measurement of the menthol content of the menthol-containing flakes was determined by GC-FID as follows.

First, weigh 0.1 g of tobacco silk containing menthol flakes, and add 10 mL of methanol to a closed container (spiral tube) with a capacity of 50 mL (in order to eliminate the influence of moisture absorption in the air, the test drug is special or For the same or higher, the new product was not exposed to the atmosphere, and the mixture was shaken for 40 minutes (200 rpm). After allowing to stand overnight, the mixture was shaken again for 40 minutes (200 rpm), and the supernatant after standing (here, diluted 10 times with methanol for GC measurement) was used as a measurement solution.

The GC-FID was set as follows, and the solution was quantitatively determined by a calibration line method.

GC-FID: Agilent 6890N Gas Chromatograph

Column: DB-WAX 30m × 530μm × 1μm constant pressure mode 5.5psi (speed: 50cm / sec)

Injection: 1.0μL

Injection port: non-split mode, 250 ° C, 5.5 psi

Oven: 80 ° C → (10 ° C / min) → 170 ° C (keep 6.0 points) (up to 220 ° C)

Detector: FID detector, 250 ° C (H ₂ : 40 mL / min, air: 450 mL / min)

Signal frequency: 20Hz

As is apparent from Table 1, the residual rate of the flavor of the cut piece containing the flavor sheet was significantly higher than when the flavor was directly added to the tobacco yarn.

Example 2

5200 parts by weight of a polysaccharide (barlan gum and tamarind gum) was added to 70,000 parts by weight of water, and the polysaccharide was sufficiently stirred and dissolved at 80 °C. To the aqueous solution of the polysaccharide, 13,000 parts by weight of 1-menthol, 455 parts by weight of a coloring agent (caramel color and cocoa powder), and 105 parts by weight of an emulsifier (lecithin) were dissolved in the aqueous solution of the polysaccharide. Water (1995 parts by weight) of an aqueous emulsifier solution was sufficiently emulsified by a homogenizer. The obtained emulsified slurry was cast in a sheet form on a substrate and dried at 70 °C. The dried flavour-containing flakes had a thickness of 0.1 mm.

The flavor-containing sheet was cut into a rectangular column of various sizes to prepare a cut piece. The size of the cut piece produced at this time is as follows.

Cut piece A: short side 1mm, long side 10mm, long side / short side ratio 10

Cut piece B: short side 1mm, long side 5mm, long side / short side ratio 5

Cut piece C: short side 2mm, long side 3mm, long side / short side ratio 1.5

In order to accelerate the volatilization of the flavor, each of the cut pieces was placed in a thermostat at a temperature of 50 ° C for 1 hour, and the weight reduction rate of the flavor was measured. The relationship between the reduction rate and the cross-sectional area/volume ratio of the cut piece is shown in Fig. 1 . As is apparent from the results shown in Fig. 1, in order to suppress the volatilization of the flavor, the cross-sectional area per volume of the cut piece can be made small. Under the above-described acceleration conditions, when the weight reduction rate is 30% or less, the concentration of the fragrance in the cigarette rod is a level which can reduce the incidence of the appearance of the cigarette (the occurrence of spots on the paper roll). Therefore, when considering the adaptability to tobacco, the cross-sectional area/volume of the cut piece is 3 or less, and it is preferable that the weight reduction rate of the fragrance is 20% or less and the cross-sectional area/volume is 2 or less.

After measuring the average particle diameters of the cut pieces A, B, and C having a weight reduction rate of 30% or less, they were placed in a small grinder (trade name: Labo Milser PLUS), and the average particle diameter after the pulverization treatment for 5 seconds was measured. At the same time, the pulverized sample was placed in a cylindrical container having an inner diameter of 60 mm, and a load of 3.0 kg was applied thereto, and the bulkiness at this time (after the crushing) was measured (the compressed volume per 1 g of the cut piece when the load was applied). The average particle size distribution is shown in Figures 2 through 4. Fig. 2 shows the result of cutting piece A, Fig. 3 shows the result of cutting piece B, and Fig. 4 shows the result of cutting piece C. In line 2 to 4, line a shows the particle size before crushing, and line b shows the particle size after crushing. Further, Table 2 shows the average particle size and bulkiness of the cut pieces A to B before and after the crushing.

From the results shown in Figs. 2 to 4 and Table 2, it was confirmed that the closer the long side/short side ratio of the cut piece is to 1, the less the crushing is affected. Therefore, in order to suppress/control the fragrance from being volatilized by the cut piece, the shape of the cut piece is first defined by the cross-sectional area/volume ratio, and then the cross-sectional area at the time of cutting is first specified, and then the long side/short side ratio is reduced, whereby the fracture prevention section can be suppressed. produce. Further, when the cigarette is manufactured by the current cigarette wrapping machine, the tobacco yarn blended with the cut piece containing the flavor sheet is adsorbed and transported on the adsorption belt of the cigarette wrapping machine, but it is preferably even perpendicular to the conveying direction in the cutting sheet. In the case where the ground is adsorbed, it can still pass without bending in the subsequent steps. Therefore, in the case where the cut piece is disposed at the center of the tobacco roll, in order to prevent breakage of the cut piece when the cigarette is wrapped, it is preferable that the long side of the cut surface of the cut piece does not reach the diameter of the cigarette rod.

After actually cutting the cut piece A and the cut piece C into the tobacco yarn by 5%, and wrapping it to a cigarette rod having a circumference of 25.2 mm, the cigarette rod was cut and all the cut pieces were collected, and the small piece was confirmed. There are very few broken pieces.
