For example, the smoking material portion 120 includes a plurality of strands of reconstituted tobacco material, one strand being approximately 10 mm to 14 mm long (eg, 12 mm) and approximately 0.8 mm to 1.2 mm wide (eg, For example, 1 mm) and the thickness may be approximately 0.08 mm to 0.12 mm (eg, 0.1 mm), but is not limited thereto.

On the other hand, recent studies on the technology of adding flavor to the aerosol provided from cigarettes are being conducted in various fields. There is a possibility that the intrinsic satisfaction of cigarettes, such as such, may be lowered.

In consideration of this, the smoking material unit 120 according to the embodiments of the present invention is filled with a mixture in which leaf tobacco and plate leaf are mixed, so as to impart flavor to the aerosol and at the same time increase the original satisfaction of cigarettes. The leaf tobacco may include at least one or more of yellow leaf seed leaf, burry leaf leaf, Maryland leaf, and orient leaf leaf, and the plate leaf may contain clove by-products, leaf tobacco by-products and pulp. there is.

Here, the weight of the plate leaf sheet included in the smoking material unit 120 relative to the total weight of the smoking material unit 120 may be approximately 1% to 25%, preferably approximately 5% to 10%. In addition, the weight of the clove by-product contained in the platelet sheet may be about 20% to 60%, preferably about 30% to 50%, more preferably about 35% to 45%, based on the total weight of the platelet sheet. there is.

As the smoking article 100 has the compounding ratio of the plate-leaf sheet in the smoking material part and the clove by-product in the plate-leaf sheet, the smoking material part 120 using a hyangaek composition, etc. without flavoring treatment or Even with a small amount of flavoring treatment, it is possible to promote the clove scent during smoking, and furthermore, it is possible to improve the sucking properties and the feeling of lightness of the smoking article, and at the same time, it is possible to prevent the occurrence of fiber odor.

More specifically, when the weight of the clove by-product contained in the leaf sheet is 50% or more, the amount of nicotine transfer is reduced and the taste decreases accordingly, as shown in Experimental Examples 1 to 3 to be described later, and 30% or less is In this case, there will be no significant effect due to the inclusion of clove by-products.

On the other hand, the clove by-product may be at least one selected from clove dust, clove calyx (clove bullet stem) and clove stem (clove stem), and the leaf tobacco by-product is dust, leaf veins (stem). It may be at least one selected from by-product) and hwangjumaek (bright tobacco stem). The particle size of the clove leaf powder may be about 0.01 mm to 2 mm, preferably about 0.1 mm to 1 mm.

In some embodiments, the combined weight of clove leaf powder and tobacco leaf powder contained in the leaflet sheet may be 75% to 85% based on the total weight of the leaflet sheet. In addition, the weight of the yellow barley contained in the plate-leaf sheet may be 2% to 8% based on the total weight of the plate-leaf sheet. Furthermore, the weight of clove leaf powder contained in the plate leaf sheet is greater than the combined weight of leaf veins, yellow veins, and pulp, and the weight of clove leaf powder contained in the plate leaf sheet is greater than the combined weight of leaf powder, vein pieces, yellow veins and pulp. can be small

Accordingly, it is possible to improve the taste of smoking articles and reduce the odor of fibers, and at the same time, it is possible to prevent the problem of deterioration of workability due to the cutting of the sheet leaf during manufacture.

On the other hand, it may be desirable to apply the clove by-product used in the plate-leaf sheet differently depending on the manufacturing method of the plate-leaf sheet.

Specifically, when the platelet sheet is a paper-making platelet sheet, the platelet sheet may preferably include only the clove leaf among clove leaf powder, clove calyx, and clove stem, which is the case of clove calyx or clove stem. This is because the application of the refining process is not easy due to the woody formation of the tissue.

On the other hand, in the case of a slurry-type leaflet sheet, it may be preferable that the leaflet sheet include clove leaf powder, clove calyx and/or clove stem. For example, the leaf sheet may contain 20% to 40% by weight of clove leaf powder, 5% to 10% by weight of clove calyx, and 5% to 10% by weight of clove stem. Through the above combination, it is possible to secure the workability of the leaf sheet and to further maximize the effect of enhancing the clove scent.

Meanwhile, invert sugar, glycerin and clove oil may be further added to the plate leaf sheet. Here, it is preferable that the weight of the invert sugar is about 1% to 5%, the weight of the glycerin is about 1% to 5%, and the weight of the clove oil is about 0.5% to 1.5%, based on the total weight of the leaf sheet .

As shown in Table 2, in Examples 1 to 2 and Comparative Examples 2 to 4 in which the clove by-product was mixed, the eugenol component was detected, and the sugar level was also increased compared to Comparative Example 1. In particular, in Examples 1 and 2, And the increase in the eugenol content was noticeable and at the same time a nicotine content substantially similar to that of Comparative Example 1 appeared, and it was expected that the clove flavor would not be impaired and the original tobacco taste would not be impaired.

In contrast, in Comparative Example 2, wherein the combined content of clove leaf powder and leaf powder of leaf tobacco was less than 75% by weight (about 65% by weight) and Comparative Example 4, in which the content of clove leaf powder was more than 50% by weight (about 55% by weight), Since the amount of nicotine in the leaf was significantly reduced compared to Comparative Example 1, it was expected that the amount of nicotine transfer during smoking and the taste of taste decreased accordingly.

In addition, in Comparative Example 3, in which the clove leaf content was less than 30% by weight (about 25% by weight), the increase in total sugar and eugenol was small along with the decrease in the nicotine content. It was also confirmed that the advantages of

On the other hand, in Comparative Example 4, although the clove leaf content was higher than in Examples 1 and 2 and Comparative Example 2, there was no significant change in the eugenol content. It was confirmed that the weight % to 50% by weight.

Experimental Example 2: Analysis of smoke components of Examples 1 to 2, and Comparative Examples 1 to 4

In order to measure changes in the composition of mainstream smoke according to embodiments of the present invention, mainstream smoke for smoking articles of each of Examples and Comparative Examples was collected. Smoking articles 4 weeks after manufacture were used, and smoke collection was repeated 3 times for each sample. Mainstream smoke was collected at a rate of 20mL per case, and the results of component analysis based on the average value of the results of three collections are shown in Table 3.

As shown in Table 3, in both Examples 1 to 2 and Comparative Examples 2 to 4 in which the clove by-product was mixed, the total particle materials (TPM) and the amount of tar were slightly increased, which was due to the increase in the amount of spices contained in the clove by-product. In Examples 1 and 2, although a portion of the leaf tobacco by-product was replaced with the clove by-product, a substantially equivalent level of nicotine content in mainstream smoke appeared, confirming that the amount of nicotine transfer was not reduced according to the content of the clove by-product.

On the contrary, in Comparative Examples 2 and 4, it can be seen that the amount of nicotine transfer was reduced compared to other Examples and Comparative Examples.

Experimental Example 3: Smoking sensory evaluation of Example 2 and Comparative Examples 1 and 2

The sensory evaluation was performed on the taste intensity, suckability satisfaction, clove scent intensity and fiber odor intensity of smoking articles. The sensory characteristic evaluation was conducted for 20 evaluation panel members using the smoking articles of Example 2 and Comparative Examples 1 and 2, and a total score of 5 was used as the standard.

2 is a view showing the smoking sensory evaluation results of smoking articles prepared according to Example 2 and Comparative Examples 1 to 2; The sensory of Comparative Example 3, in which the results of analysis of components in leaves or mainstream smoke components are relatively unfavorable compared to other Examples, Example 1 with similar sensory property results to Example 2, and Comparative Example 4 with similar sensory property results with Comparative Example 2 Evaluation results are omitted from FIG. 2 for clarity of explanation.

Referring to FIG. 2 , it was found that the suckability satisfaction and clove flavor strength of Examples 2 and 2 were higher than those of Comparative Example 1 in which the clove by-product was not contained.

However, in Comparative Example 2, compared to Comparative Example 1, the taste strength was decreased by about 5% and the fiber odor strength was increased by about 46%. It can be seen that the decrease

On the contrary, the taste strength, suckability satisfaction, and clove scent strength of the smoking article according to Example 2 were all increased compared to Comparative Example 1, and the fiber odor strength of the smoking article according to Example 2 was substantially equal to that of Comparative Example 1. could confirm that Through this, it can be seen that, in the case of the smoking article according to Examples 1 or 2, the clove flavor is improved and the sensory characteristics inherent in tobacco are also improved.

Example 3

Smoking as in Example 2, except that about 3% by weight of invert sugar, about 3% by weight of glycerin, and about 0.5% by weight of clove oil were additionally added based on the total weight of the leaf sheet included in the smoking material part The article was made.

Example 4

A smoking article was prepared in the same manner as in Example 3, except that about 1.0% by weight of clove oil was added.

Example 5

A smoking article was prepared in the same manner as in Example 3, except that about 1.5% by weight of clove oil was added.

Example 6

A smoking article was prepared in the same manner as in Example 3, except that about 2.0% by weight of clove oil was added.

Experimental Example 4: Analysis of components in leaves of Examples 2 to 6

In order to observe the component change in leaves according to the flavoring amount of clove oil, the content of eugenol contained in the smoking material part was analyzed. Smoking articles 4 weeks after manufacture were used, and in Table 4, flavoring conditions and eugenol levels for each example were described.

As shown in Table 4, it can be seen that the eugenol level generally increases as the flavoring solution containing clove oil is added. In Examples 5 and 6, despite the increase in the amount of clove oil added compared to Example 4 And there was no significant change in the eugenol content, and it can be inferred that eugenol above the standard value is lost due to volatilization during storage of smoking articles. Accordingly, it can be confirmed that the flavoring effect is most pronounced in Example 4, in which 1.0% by weight of clove oil is added.

Experimental Example 5: Smoking sensory evaluation of Examples 2, 4, and 6

The sensory evaluation was performed on the taste intensity, suckability satisfaction, clove scent intensity and fiber odor intensity of smoking articles. The sensory characteristic evaluation was conducted for 20 evaluation panel members using the smoking articles of Examples 2, 4, and 6, and a total of 5 points was used as the standard.
