Through the results of Table 2, it can be confirmed that the amount of carbon monoxide (CO) generated during smoking is reduced by applying the cocoa wrapper, and in particular, the amount of tar per puff and the amount of carbon monoxide relative to the total amount of tar are both significant. It was confirmed that Example 1 containing cacao husk had a mainstream smoke reforming effect compared to Comparative Example.

<Experimental Example 3: Evaluation of surface/back surface properties of cigarette paper according to Example 1 and Comparative Example 1>
In order to confirm changes in the surface and back surface properties of the cocoa wrappers according to the examples of the present invention, the smoothness, roughness and coefficient of friction of the front surface and the back surface were analyzed and shown in Table 3. .

Through the results of Table 3, it can be confirmed that the inclusion of cacao husk in the cigarette paper reduced the smoothness and increased the roughness on both the front and back sides of the cigarette paper, which indicated that the cigarette process conditions need to be different from the conventional.

<Comparative Example 3>
Cigarette paper for regular cigarettes having the same physical properties as in Comparative Example 1 and having a circumference of approximately 24.6 mm was used, the process speed was 3500 cpm, the cigarette paper adhesion process was performed under the conditions of a glue amount of 13 g/500 m and a temperature of 250 ° C. , the LIP banding process was carried out under conditions of a pressure of 4.0 bar and a drying temperature of 240°C. The cigarette was formed with first and second LIP bands spaced apart in the upstream and downstream direction of the cigarette, each having a width of 7 mm and a thickness of 28 um.

<Example 5>
A cigarette was manufactured in the same process as in Comparative Example 3, except that the cigarette paper for regular cigarettes having the same physical properties as in Example 1 was used.

<Example 6>
A cigarette was manufactured in the same process as in Example 5, except that the amount of glue was changed to 18 g/500 m.

<Example 7>
Using cigarette paper for ultra-slim cigarettes having the same physical properties as in Example 3 and having a circumference of approximately 17 mm, the process speed was 3500 cpm, the cigarette paper adhesion process was performed under the conditions of a glue amount of 18 g/500 m and a temperature of 330 ° C. , the LIP banding process was carried out at a pressure of 2.5 bar and a drying temperature of 240°C.

<Example 11>
A cigarette was manufactured in the same process as in Example 7, except that the cigarette paper for ultra-slim cigarettes having the same physical properties as in Example 1 was used.

<Experimental Example 4: Evaluation of extinguishing rate according to process conditions>
The extinguishing rate of 20 cigarettes according to each of the comparative example and the example was measured and shown in Table 4. In Table 4, primary fire extinguishing is when the combustion of cigarettes in the first LIP band is extinguished, and secondary fire extinguishing is when the cigarettes in the second LIP band located downstream of the first LIP band are extinguished. Indicates when the combustion is extinguished.

As shown in Table 4, in the case of Comparative Example 3, in which cigarette paper containing no cocoa husk was applied, the extinguishing rate was 75% despite the relatively small amount of glue, low bonding temperature, and high drying temperature. On the other hand, in Examples 5 to 9 containing cacao husk, it can be confirmed that there is difficulty in ensuring the extinguishing rate even if cigarettes are manufactured under the same conditions as in Comparative Example 3 or under more severe conditions. Specifically, in all of Examples 7-9, which applied the ultra-slim cigarette paper of Example 3, which contained 1.2% burn improver and 19% filler, extinguishing It can be verified that an upward rate is not possible.

In contrast, among the examples in which the cigarette paper of Example 1 containing 0.7% of the combustion improver and 6.47% of the filler was applied, the process speed was 3500 cpm and the amount of glue in the cigarette paper bonding process was It can be seen that the extinguishing rate of 100% was achieved in Examples 10 and 11 with 18 g/500 m and a temperature of 330°C.

Also, through comparison between Examples 10 and 11, it was confirmed that the pressure and drying temperature conditions of the LIP banding process differed depending on the circumference of the cigarette. When the cigarette paper according to Example 1 of the regular standard was applied, an excellent extinguishing rate appeared only under the condition that the LIP banding process pressure was 4.0 bar and the drying temperature was 180 ° C., but the super slim When the cigarette paper according to Example 1 of the standard was applied, an excellent extinguishing rate appeared even under the condition that the LIP band process pressure was 2.5 bar and the drying temperature was 240°C.

<Comparative Example 4>
Cigarettes were made identical to Example 1, except that the first LIP band had a width of 7 mm and a thickness of 17 um, and the second LIP band had a width of 8 mm and a thickness of 24 um.

<Comparative Example 5>
Cigarettes were made identical to Example 4, except that the first LIP band had a width of 7 mm and a thickness of 17 um, and the second LIP band had a width of 8 mm and a thickness of 24 um.

<Comparative Example 6>
Cigarettes were made identical to Example 1, except that the first LIP band and the second LIP band both had a width of 7 mm and a thickness of 22 um.

<Comparative Example 7>
Cigarettes were made identical to Example 4, except that the first LIP band and the second LIP band both had a width of 7 mm and a thickness of 22 um.

<Experimental Example 5: Evaluation of extinguishing rate according to LIP band standard>
The extinguishing rate of 20 cigarettes according to each of the comparative example and the example was measured and shown in Table 5.

As shown in Table 5, both the cigarette papers having the physical properties of Examples 1 and 4 had excellent extinguishing rate only when the first and second LIP bands respectively had a width of 7 mm and a thickness of 28 um. can be seen to have appeared. Taking into consideration the fact that an excellent extinguishing rate is ensured when the LIP band standards of Comparative Examples 4 to 7 are applied to cigarette paper to which cocoa husk is not applied, the LIP band is obtained by including cocoa husk in the cigarette paper. It was confirmed that the standard also required a new design as in this example.

<Experimental Example 6: Evaluation of Hue of Cigarettes in Example 1 and Comparative Example 1>
After measuring 10 cigarettes each of Example 1 and Comparative Example 1 with CIELAB color space data, average values were calculated and shown in Table 6.

As shown in Table 6, each of the 10 cigarettes according to Comparative Example 1 containing no cacao husk had an L* value of approximately 44-50, an a* value of approximately 7-13, and a b* value of approximately 13-19. was analyzed to be In contrast, each of the 10 cigarettes according to Example 1 containing cocoa husk had an L* value of about 60-75, an a* value of about 1.5-7.5, and a b* value of about 7.5. 0 to 11.0, whereby the cocoa husk is not contained only in the husk particles (120 aH) shown in FIG. It can be confirmed that changes in the hue characteristics and other physical characteristics described above were induced.

<Comparative Example 8>
A cigarette was produced by removing the unflavored filter portion of the cigarette according to Comparative Example 1 and using the TJNS filter flavored with green apple herb.

<Experimental Example 8: Comparative Examples 1 and 8, evaluation of smoking sensation of cigarettes according to Example 1>
In order to confirm the sensory characteristics of cigarettes in which the cigarette paper containing the cocoa husk of the present invention was adopted, the smoking articles according to Example 1, Comparative Example 1 and Comparative Example 8 were evaluated for their aroma intensity during smoking and aroma satisfaction during smoking. , impact feeling during smoking, taste during smoking, and degree of satisfaction after smoking were sensory evaluated.

Sensory characteristics were evaluated using the smoking articles of Example 1, Comparative Example 1, and Comparative Example 8 by an evaluation panel of 20 persons, based on a total of 8 points.

FIG. 2 shows the results of a smoking sensory evaluation of the cigarettes manufactured according to Example 1, Comparative Examples 1 and 8 and then stored at room temperature for 4 weeks.

Referring to FIG. 2, it can be confirmed that the cigarette according to Comparative Example 8 using the TJNS filter has higher aroma intensity and satisfaction during smoking than the cigarette according to Comparative Example 1 using a filter that is not flavored. On the other hand, Example 1, which contains cacao husk, shows a significant increase in the numerical values for the aroma intensity during smoking compared to Comparative Example 1, even though it employs an unflavored filter. As for the degree of satisfaction with fragrance, a higher score appeared compared to Comparative Example 8 using the TJNS filter. Compared to Comparative Example 8, in which a strong menthol aroma is directly transmitted to the smoker by treating the perfume liquid in the filter itself, this is because the cacao aroma expressed from the cigarette paper by burning the cigarette paper can be absorbed by the smoker. It is presumed that the level of satisfaction was further increased by being kindly communicated to the person.

No significant difference was derived from the impact feeling during smoking, but the degree of satisfaction after smoking increased slightly in Example 1, in which the cocoa wrapper was adopted, and the feeling of smoking during smoking was also improved in Comparative Example 1. and 8 were confirmed to have increased. This is presumed to be the effect of the mainstream smoke reforming described through Experimental Example 2.

Those skilled in the art related to the embodiments will understand that the present embodiments can be embodied in modified forms without departing from the essential characteristics described above. Accordingly, the disclosed method should be considered from an illustrative rather than a restrictive point of view. The scope of the present invention is indicated in the appended claims rather than in the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
