≪ Tobacco material of the present invention &

The tobacco material of the present invention comprises particles of leaf tobacco having an average particle diameter of 30 탆 or less and a liquid dispersion medium for dispersing the particles.

<Particle of leaf tobacco>

The particles of the leaf tobacco included in the tobacco material of the present invention can be obtained, for example, by the following methods.

The kind that can be used as the leaf tobacco is not particularly limited, and the main leaf tobacco raw material of yellow species, burley species, native species, Orient leaf, and fermented leaves using them are suitably used. In addition, for these leaf tobacco, it is also possible to use middle-bone tobacco, expanded tobacco, and sheet tobacco which have been treated.

The leaf tobacco mentioned above is required to uniformly add a very small amount to a smoking article in that it exhibits distinctive aroma of flavor.

These leaf tobacco are subjected to ordinary drying treatment and then coarsely pulverized by a usual coarse grinder.

There is no particular limitation on the drying process or the coarse grinding process by the coarse grinder, and the average particle size of the ground tobacco powder is in the range of several hundreds of micrometers to several millimeters.

A liquid dispersion medium is added to the crude crushed leaf tobacco, followed by stirring and mixing.

The resulting mixture is pulverized using a wet pulverizer (for example, MIC-2: manufactured by NARIKIKA ISASE CHEMICAL CO., LTD.). The number of revolutions of the machine is usually 1100 to 1300 rpm, and the milling time is 5 to 100 minutes.

By carrying out such an operation, the average particle size of the particles of the leaf tobacco is pulverized to 30 mu m or less.

Further, in the case of obtaining a dispersion dispersed in a liquid, a wet pulverizer is generally used, but a tobacco material of the present invention can also be obtained by using a dry pulverizer. Specifically, the crude tobacco powder is finely pulverized to an average particle size of 30 mu m or less using a dry milling machine such as a jet mill, and then a liquid dispersion medium is added and stirred and mixed.

The average particle diameter referred to in the present invention can be obtained by a laser diffraction / scattering method, and a refractive index (refractive index) is measured using a laser diffraction particle size distribution measurement apparatus (for example, Shimadzu nanoparticle diameter distribution measurement apparatus SALD-2100) Is set in the range of 1.60-0.10i.

Using this measurement principle and measuring apparatus, the average value of the particle diameters obtained by the analysis software attached to the measuring apparatus is taken as the average particle diameter.

The average particle diameter of the particles of the leaf tobacco included in the tobacco material of the present invention is 30 占 퐉 or less.

The particles of the fine pulverized leaf tobacco have such an average particle size that the particles of the leaf tobacco in the tobacco material are easily dispersed uniformly, and the flavor of the flavor to the smoking article can be imparted uniformly.

The lower limit value of the average particle diameter of the particles of the leaf tobacco is usually 5 mu m or more and 8 mu m or more.

In order to increase the average particle size of the particles of the leaf tobacco, it is possible to shorten the pulverization time or adjust the dispersion medium to a low point by using a pulverizer.

As the dispersion medium, at least one selected from water, monohydric alcohols, polyhydric alcohols, sugar alcohols, sugars and polyhydric alcohol esters can be selected.

By using such a dispersion medium, the average particle diameter of the leaf tobacco can be adjusted to a desired value.

Monovalent aliphatic alcohols such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 2,2-dimethyl ethanol and cyclohexanol, Monovalent alcohols having a substituent, other monohydric alcohols containing at least one halogen element, and monohydric alcohols having at least one ether bond.

The polyhydric alcohol in the present invention is a generic term of compounds having two or more hydroxyl groups in one molecule and is not particularly limited. Examples thereof include glycerin and propylene glycol. Examples of sugar alcohols include sorbitol, maltitol, xylitol, erythritol, lactitol, sorbitan, xylose, arabinose, mannose and trehalose. Examples of the saccharides include lactose, sugar, coupling sugar, glucose, starch syrup, oligosaccharide syrup, maltose syrup, maltose, isomerized sugar, fructose, reduced maltose, reduced starch syrup and honey .

Examples of polyhydric alcohol esters include fatty acid polyhydric alcohol esters. Fatty acid polyhydric alcohol esters include fatty acid triglycerides.

The dispersion medium is preferably liquid at room temperature, but is not limited thereto and may be solid. The solid at room temperature can be used after being dissolved in the other dispersion medium (water, glycerin) described above.

Of these, water alone or a combination of water and water is used.

Of these, use of a mixed dispersion medium of water and glycerin is preferable from the viewpoint of preparation of an average particle diameter when the leaf tobacco is finely ground to a desired range.

There is no particular limitation on the mixing ratio of water and other dispersion medium, and in the case of water and glycerin, mixing can be carried out at an arbitrary ratio.

The tobacco product to which the tobacco material of the present invention is imparted is not particularly limited and examples of the smoking article include smoking articles such as cigarettes, cigarette tobacco, pipe, water cigarette, tobacco, chewing tobacco, .

Since the tobacco material of the present invention is dispersed in the liquid dispersion medium as described above, it is possible to take a slurry-like form.

In order to take such a slurry-like aspect, the weight ratio of the liquid dispersion medium to the leaf tobacco particles is usually from 1.5 to 99 (1 to 40% by weight of tobacco particles to tobacco material) It is the sun to give.

When the tobacco material of the present invention takes the form of a slurry, the tobacco material of the present invention is applied to the smoking article using, for example, spray, etc., so that the tobacco material is evenly and uniformly added to the smoking article. By this means, the fragrance ingredient contained in the tobacco material can be uniformly imparted to the tobacco product.

The subject to which the tobacco material of the present invention is to be applied may be any one of leaf tobacco immediately after harvesting, dried leaf tobacco, leaf tobacco added with fragrance, shred tobacco, and cigarette.

When the cigarette material of the present invention is added to a cigarette, the cigarette material may be added to a cigarette, a wrapper, a filter, a tip paper, etc. constituting the cigarette. The number of sites to be added may be one, or two or more sites such as tobacco flesh and tip paper may be added. In addition, it is also possible to impart different flavor to the cigarette product such as cigarette during smoking by adding a cigarette material obtainable from different types of cigarettes, in view of the difference in the wrapper.

When the tobacco material is added to the filter of the cigarette, the filter may be impregnated.

In the case where the tobacco product includes tobacco flesh, the weight ratio of the tobacco material and tobacco flesh of the present invention to the tobacco product in consideration of imparting the desired fragrance to the tobacco product is such that the tobacco particles Is 0.01 to 5% by weight with respect to the weight of tobacco.

When a tobacco leaf having a strong flavor is used for a tobacco material, a smaller weight percentage (for example, about 0.01 to 0.1%) may be used.

There is no particular limitation on the kind of tobacco tobacco to which the tobacco material is added.

In the tobacco material of the present invention, various additives may be added in addition to the particles of the finely pulverized leaf tobacco. For example, a food material such as spearmint leaves, peppermint leaves, tea leaves such as green tea, coffee, cocoa, cardamon, menthol, and sugar for flavor design, and gluten Thickening polysaccharides such as pectin and various emulsifying agents and glue agents such as carboxymethylcellulose sodium (CMC) and hardeners for improving handling after addition to leaf tobacco. have.

The timing of adding the additive is not specifically defined, but may be added before pulverizing the leaf tobacco material and finely pulverized together, or may be added to the pulverized slurry.

These additives can be mixed with the particles of the leaf tobacco at any ratio.

The tobacco material of the present invention includes the above-mentioned particles of the leaf tobacco having the specific average particle diameter and the dispersion medium containing 90 wt% or more, more preferably 95 wt% or more of the total amount of the tobacco material.

Example

The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to the description of the following examples without departing from the gist thereof.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to the description of the following examples unless it departs from the gist of the present invention.

&Lt; Example 1 &gt;

In order to confirm whether or not flavorings can be imparted evenly to a smoking article using the tobacco material of the present invention, the following test was conducted.

1. About tobacco

In both of Example 1 and Comparative Example 1, cigarette flesh used in commercially available cigarettes was used.

2. Slurrying of leaf tobacco raw material

1) Tobacco, a kind of fermented leaves that is easy to detect by adding a small amount of flavor as a raw material of leaf tobacco, is adopted. This leaf tobacco raw material was pulverized with a dry pulverizer (Wonder Blender WB-1; Osaka Chemical Co., Ltd.) to obtain a leaf tobacco powder having a size of 70 to 250 mu m.

2) To 250 g of rat tobacco powder, 800 g of glycerol and 200 g of water were added as a dispersion medium, and the mixture was stirred with a spatula to obtain a mixed liquid.

3) The above mixed solution was treated with a wet pulverizer (MICROS MIC-2; manufactured by NARAGICA ISEI SAKUSHO CO., LTD.) At 1200 rpm for 10 minutes.

The average particle diameter of the particles of the leaf tobacco contained in the obtained slurry-like tobacco solution (tobacco material) was about 8.8 mu m.

3. Preparation of cigarettes sprayed with slurry of tobaccos of Latakia on tobacco liquid (tobacco material)

The method of preparing the cigarette sample of Table 1 of the experimental results is shown below.

1) Preparation of S-1 cigarettes; To 100 g of tobacco, the solution prepared in 2.3) was precisely sprayed using 0.05 g (the weight of the rat tobacco cigarette was 0.01 g), and air dried. I used this flesh to create a cigarette.

2) Preparation of S-2 cigarettes; For 100g of tobacco, 2. 5g of the solution prepared in 3) was precisely sprayed using a spray of Latakia tobacco (0.1g), and then air-dried. I used this flesh to create a cigarette.

3) Preparation of S-3 cigarettes; For 100g of tobacco, the solution prepared in 3) was precisely sprayed with 5g (the weight of rat tobacco cigarette was 1g) and then air-dried. I used this flesh to create a cigarette.

4) Preparation of S-4 cigarettes; For 100g of tobacco, the solution prepared in 2.3) was precisely sprayed with 25g (the weight of Latakia cigarette was 5g) and then air-dried. I used this flesh to create a cigarette.

&Lt; Comparative Example 1 &

Compared to (Cigarette blended with Latakia tobacco)

1% by weight and 5% by weight were added to commercial tobacco flesh, respectively, and they were sufficiently blended. A cigarette was made using a blend of flesh. Sample names for each cigarette were K-1 and K-2.

In addition, a commercial cigarette (not blending Latakia flesh) was used to prepare a cigarette, and this was controlled.

<Sensory Evaluation>

(Evaluation of non-uniformity of flavorings caused by smoking)

The evaluated samples are six kinds of K-1, K-2, S-1, S-2, S-3 and S-4 prepared above. The "non-uniformity of flavor" of each sample and the "change of flavor" when compared with the control were evaluated by two choices of "good" or "no". The order of smoking was made in the order of each sample from the control. The number of cigarettes was instructed to be 5 puffs or more. Twenty patients (age 40 ± 7 years, all male) were evaluated.

(Evaluation results)

The evaluation results are shown in Table 1 below.

&Lt; Evaluation of Example 1 and Comparative Example 1 &gt;

A tobacco of one kind of fermented leaves was made into a slurry, and a cigarette was sprayed by spraying it on tobacco (Example 1). On the other hand, as a comparative object, a cigarette in which flesh of Latakia tobacco was blended at a certain ratio was prepared (Comparative Example 1). The cigarettes produced in Example 1 and Comparative Example 1 were checked for flavor by smoking, and as a result, in the cigarette of the present invention wherein the cigarette material of the present invention was spray-turned, the existing blend method (tobacco flesh and tobacco separately mixed ). Thus, it was confirmed that even when a small amount of the tobacco material of the present invention was used, flavor stones could be uniformly imparted to smoking articles such as cigarettes.

Thus, by utilizing the tobacco material of the present invention, it becomes possible to design a fine flavored sake of a smoking article.

&Lt; Example 2 and Comparative Example 2 &gt;

1. Tobacco raw materials

As in Example 1 and Comparative Example 1, commercially available tobacco flesh was used.

2. Preparation of menthol-modified tobacco raw materials

A 50 wt% menthol solution was prepared and 20 g was uniformly dispersed in 90 g of the tobacco raw material. After dispersing, the mixture was allowed to stand for at least one day, and the menthol was evenly distributed. The menthol concentration of the tobacco raw material was measured and found to be 10.8% by weight.

Hereinafter, the tobacco raw material that consumes the tobacco raw material and the menthol-modified tobacco is abbreviated to menthol-flavored carcass.

3. Slurry (solution) of menthol-modified flesh

1) Menthol flavored flesh was pulverized with a dry pulverizer (Wonder Blender WB-1; Osaka Chemical) to obtain a leaf tobacco powder having a size of 70 to 250 mu m.

2) 800 g of glycerol and 200 g of water were added as a dispersion medium to 250 g of tobacco powder of menthol flavor and stirred with a spatula to obtain a mixed liquid.

3) The above mixed solution was treated with a wet pulverizer (MICROS MIC-2; manufactured by NARAGICA ISEI SAKUSHO CO., LTD.) At 1200 rpm for 10 minutes.

4) The menthol concentration of the tobacco liquid (tobacco material) on the obtained slurry was 2.2% by weight.

The mean particle size of the particles of the leaf tobacco was 15.6 占 퐉.

4. Preparation of a cigarette sprayed with a cigarette liquid on a slurry of menthol-flavored flesh

The preparation methods of the cigarette samples of Tables 2 and 3 of the experimental results are shown below.

1) Preparation of T-1 cigarettes; For 99g of tobacco, the solution prepared in 4) was precisely sprayed using a 5g sprayer and then air-dried. I used this flesh to create a cigarette.

2) Preparation of T-5 cigarettes; For 95g of tobacco, the solution prepared in 3.4) was precisely sprayed using a 25g sprayer and then air-dried. I used this flesh to create a cigarette.

5. Preparation of comparative subjects (cigarettes blended with menthol flesh)

Menthol flesh flesh was added to 5, 10, and 20 wt% of flesh without menthol flesh, respectively, and blended sufficiently. A cigarette was made using a blend of flesh. Sample names of each cigarette were U-5, U-10 and U-20.

6. Analysis of distribution irregularity of menthol

1) Each sample prepared above; (See Fig. 1) every 4 mm of the cigarettes of T-1, T-5, U-5, U-10 and U-20. The cutting position was started from a position 4 mm away from the filter unit and cut to a position 44 mm away from the filter unit. That is, ten cut pieces of 4 mm of the rod were prepared for each sample.

2) Menthol concentration was analyzed for each cut piece of each sample. The results are shown in Table 2. The mean value, standard deviation and coefficient of variation of the menthol concentration of the cut pieces of each sample were obtained. The results are shown in Table 3.

As described above, the cigarette material containing the menthol is finely pulverized with a pulverizer to prepare a cigarette material containing the cigarette particles having the particle size specified in the present invention, and the cigarette having the tobacco flesh sprayed by spraying I wrote. On the other hand, as a comparison object, a cigarette in which menthol-added tobacco raw materials were blended (blended) at a predetermined ratio was prepared.

The content of menthol was quantitatively analyzed by gas chromatography on these cigarettes.

As shown in Table 3, when the cigarette material of the present invention was applied to a cigarette, as compared with the case of using the existing blend method (mixing tobacco and tobacco separately), the menthol concentration It was found that the leaves of the cigarette were uniformly present in the cigarette with a very small deviation and the undifferentiated leaf tobacco raw material. In particular, it was found that even when the amount of tobacco material added was small, the variation in the concentration of each cutting piece was small (the coefficient of variation was small).

Thus, by utilizing the tobacco material of the present invention, it becomes possible to design a fine flavored sake of a smoking article.

&Lt; Example 3 &gt;

In the same manner as in Example 1, the kind of leaf tobacco raw material was changed to produce a slurry-like tobacco liquid (tobacco material). Regarding the kind of each leaf tobacco raw material and the method of treatment, the conditions shown in the following Table 4 were used.

The average particle diameter was determined by setting the refractive index to 1.60-0.10i using Shimadzu Seisakusho SALD-2100.

Tobacco was finely pulverized using a pulverizer under the conditions shown in Table 4 to obtain a slurry-like tobacco solution (tobacco material) containing particles of leaf tobacco having an average particle diameter of 8.8 to 26.5 mu m. A tobacco material having leaf tobacco particles having an average particle size of 30 占 퐉 or less as defined in the present invention was obtained from all the samples.

Industrial availability

The tobacco material of the present invention is excellent as a means for giving a flavor to a tobacco product such as a smoking article in that it can uniformly add flavor to a variety of smoking articles in a very small amount. In addition, since the tobacco material of the present invention contains a leaf tobacco not subjected to chemical treatment or the like, the original flavor of the tobacco is maintained.
