Alpha starch may be used in an amount of about 3% to 20% by weight based on the total coating composition, maltodextrin may be used in an amount of about 5% to about 40% by weight based on the total coating composition, and ethanol may be used in an amount of about 3% to 20% by weight based on the total coating composition. 10% to about 40% by weight may be used. Ethanol is vaporized in the manufacturing process of the smoking material wrapper 120a, and may not be included in the LIP band. The coating composition also includes water. For example, about 30% to 80% by weight of water may be used. Water is vaporized in the manufacturing process of the cigarette paper, so it may not be included in the LIP band. The content of solids in the coating composition may be approximately greater than 27 to less than 38 weight percent.

In order to secure the above-described effects and achieve an appropriate digestibility, at least one LIP band formed on the smoking material wrapper 120a of the present invention has a width of about 6.5mm to 7.5mm (for example, about 7mm), The forming process of the LIP band, that is, the uneven depth of the roller used in the coating process may be about 26um to 30um (eg, about 28um).

Meanwhile, the number, shape, and spacing between the plurality of LIP bands may be variously modified.

In addition, when the smoking material wrapper 120a has the same surface/back surface smoothness, surface/back roughness, and surface/back surface friction coefficient, the LIP band forming process is approximately 2.0 bar to 5.0 bar in order to achieve an appropriate digestibility. It may be carried out under pressure and a drying temperature of approximately 150°C to 280°C. More specifically, the pressure and drying temperature of the LIP band forming process may be different depending on the circumference or diameter of the smoking article 100 . For example, when the circumference of the smoking article 100 is 15 mm to 18 mm, the LIP band forming process may be performed under a pressure of about 2.0 bar to 3.0 bar and a drying temperature of about 200° C. to 280° C., the smoking When the circumference of the article 100 is 23 mm to 26 mm, the LIP band forming process may be performed under a pressure of about 3.5 bar to 5.0 bar and a drying temperature of about 150° C. to 200° C. Preferably, when the circumference of the smoking article 100 is 15 mm to 18 mm, the LIP band forming process may be performed under a pressure of about 2.3 bar to 2.7 bar and a drying temperature of about 230° C. to 250° C., and the smoking article The LIP band forming process in the case where the circumference of (100) is 23mm to 26mm may be performed under a pressure of approximately 3.8bar to 4.2bar and a drying temperature of approximately 170°C to 190°C.

Experimental Example 1: Evaluation of physical properties of cigarettes according to Comparative Example 1 and Examples 1 to 4

In order to confirm the physical properties of the cigarette when the cigarette paper according to the embodiments of the present invention is applied, the porosity, basis weight, tensile strength, elongation, and burning rate of the cigarette paper were analyzed and shown in Table 1.

division	Qigongdo (CU)	basis weight (gsm)	Tensile strength (kgf/26.5mm)	Elongation (%)	Combustion rate (sec)
Comparative Example 1	50	46	1.9	0.7	98
Example 1	49	46.4	2.79	1.4	134
Example 2	42	45.4	2.6	1.6	116
Example 3	49.4	46	2.4	1.3	106.8
Example 4	37	44.5	2.83	1.61	114

As shown in Table 1, it was confirmed that there was no significant change in physical properties in the porosity and basis weight of Comparative Examples and Examples. Accordingly, even if cacao husk was contained in the cigarette paper, the physical properties in terms of porosity and basis weight were It can be confirmed that there is no deterioration. It can be seen that in Examples 1 to 4 containing cacao husk, tensile strength and elongation were increased compared to Comparative Example 1 containing no cacao husk. In addition, it can be seen that in Examples 1 to 4 containing cacao husk, the combustion rate was increased compared to Comparative Example 1 not containing cacao husk, and in relation to this, the total number of puffs of the cigarette according to Comparative Example 1 was 8 It was confirmed that the total number of puffs of the cigarette according to Examples 1 to 4 was 10 to 12 times.

Comparative Example 2

The same cigarette as in Comparative Example 1 was prepared, except that white cigarette paper was used instead of the cigarette wrapper cigarette paper of Comparative Example 1.

Experimental Example 2: Mainstream smoke component analysis of cigarettes according to Example 1 and Comparative Examples 1 and 2

In order to confirm the effect of modifying mainstream smoke by application of the cacao wrapper according to the embodiment of the present invention, the main smoke components such as the amount of tar, nicotine, and carbon monoxide generated during smoking were analyzed and shown in Table 2.

division	Tar (mg/cig)	Nicotine (mg/cig)	Nicotine/Tar	CO (mg/cig)	Puff (sashimi)	Co/Tar	Tar/Puff (mg/puff)	Nicotine/Puff (mg/ puff)
Example 1	1.8	0.10	0.054	1.81	11.14	1.03	0.158	0.009
Comparative Example 1	1.8	0.10	0.056	2.0	9.8	1.11	0.184	0.010
Comparative Example 2	2.3	0.21	0.091	3.5	8.4	1.52	0.274	0.025

From the results in Table 2, it can be confirmed that the amount of carbon monoxide (CO) generated during smoking decreased according to the application of the cacao wrapper, and in particular, both the amount of tar per puff and the amount of carbon monoxide compared to the total amount of tar showed a significant decrease. It was confirmed that there was a mainstream smoke reforming effect compared to Comparative Examples in Example 1 containing

Experimental Example 3: Evaluation of the surface/back side characteristics of the cigarette paper according to Example 1 and Comparative Example 1

In order to confirm the change in the surface and back properties of the cacao wrapper according to the embodiment of the present invention, the smoothness, roughness, and friction coefficient of the surface and the back surface were analyzed and shown in Table 3.

division		Smoothness (s/2.5kpa)	Roughness (um)	coefficient of friction
Example 1	surface	8.995	120.0921	60.6
	back side	1.632	658.3251	69
Comparative Example 1	surface	56.12	19.02024	47.4
	back side	36.48	29.26042	39.8

From the results in Table 3, it can be confirmed that, as the cigarette paper contains cacao husk, the smoothness is lowered and the roughness is increased on both the surface and the back side of the cigarette paper, and accordingly, the process conditions of the cigarette need to be different from the existing ones. It can be predicted that there is

Comparative Example 3

Using a regular cigarette paper having the same physical properties as in Comparative Example 1 with a perimeter of about 24.6 mm, the process speed is 3500 cpm, the cigarette paper adhesion process is under the conditions of a glue amount of 13 g/500 m and a temperature of 250 ° C., the LIP band The process was carried out under the conditions of a pressure of 4.0 bar and a drying temperature of 240 °C. First and second LIP bands spaced apart from each other in the up-stream direction of the cigarette, each having a width of 7 mm and a thickness of 28 μm, were formed in the cigarette.

Example 7

Using the ultra-slim cigarette paper having the same physical properties as in Example 3, the perimeter of the cigarette is about 17 mm, the process speed is 3500 cpm, the cigarette paper bonding process is under the conditions of glue amount 18 g / 500 m and temperature 330 ° C., LIP band process It was carried out under the conditions of a pressure of 2.5 bar and a drying temperature of 240 °C. First and second LIP bands of the same standard as in Comparative Example 3 were formed.

Example 8

A cigarette was prepared in the same manner as in Example 7, except that the pressure was changed to 4.0 bar.

Example 11

A cigarette was prepared in the same manner as in Example 7, except that the ultra-slim cigarette paper having the same physical properties as in Example 1 was used.

Experimental Example 4: Evaluation of digestibility according to process conditions

The digestibility of 20 cigarettes according to Comparative Examples and Examples was measured, and is shown in Table 4. In Table 4, the primary extinguishing is a case in which the combustion of the cigarette in the first LIP band is extinguished, and the secondary extinguishing is the case in which the combustion of the cigarette in the second LIP band located downstream than the first LIP band is extinguished. indicates the case.

division	cigarette paper		process speed	cigarette paper adhesion		LIP band process		Digestibility (20 pieces)
	Properties	standard	cpm	Glue (g/500m)	Temperature (℃)	pressure (bar)	Drying temperature (℃)	primary digestion	secondary digestion	Fail	result(%)

Example 10	Same as Example 1	regular						19	One	0	100
Example 11	Same as Example 1	super slim				2.5	240	20	0	0	100

As shown in Table 4, in Comparative Example 3 to which the cigarette paper containing no cacao husk was applied, a digestibility of 75% was secured despite a relatively small amount of glue, a low adhesion temperature, and a high drying temperature, whereas the cacao husk It can be seen that in Examples 5 to 9 containing the cigarette, there is a difficulty in securing digestibility even when the cigarette is manufactured under the same or harsher conditions as in Comparative Example 3. Specifically, an implementation comprising 1.2% of a smoker and 19% of a filler In all of Examples 7-9 to which the ultra-slim standard cigarette paper of Example 3 was applied, it can be confirmed that the digestibility was not increased despite the application of various process conditions.

On the other hand, among the examples to which the cigarette paper of Example 1 containing 0.7% of the supporting agent and 6.47% of the filler was applied, the process speed was 3500 cpm, the amount of glue in the cigarette paper adhesion process was 18 g/500 m, and the temperature was 330 ° C. Example 10 and 11, it can be confirmed that 100% digestibility was achieved.

Furthermore, through comparison between Examples 10 and 11, it was confirmed that the pressure and drying temperature conditions of the LIP band process were different depending on the circumference of the cigarette. When the cigarette paper according to Example 1 of the regular standard was applied, excellent digestibility was shown only under the condition that the LIP band process pressure was 4.0 bar and the drying temperature was 180 ° C. However, when the cigarette paper according to Example 1 of the ultra-slim standard was applied Excellent digestibility was shown even under the conditions of LIP band process pressure of 2.5 bar and drying temperature of 240 °C.

Comparative Example 4

The same cigarette as in Example 1 was prepared, except that the first LIP band had a width of 7 mm and a thickness of 17 μm and the second LIP band had a width of 8 mm and a thickness of 24 μm.

Comparative Example 5

The same cigarette as Example 4 was prepared, except that the first LIP band had a width of 7 mm and a thickness of 17 μm and the second LIP band had a width of 8 mm and a thickness of 24 μm.

Comparative Example 6

The same cigarette as in Example 1 was prepared, except that the first LIP band and the second LIP band both had a width of 7 mm and a thickness of 22 μm.

Comparative Example 7

The same cigarette as Example 4 was prepared, except that the first LIP band and the second LIP band both had a width of 7 mm and a thickness of 22 μm.

Experimental Example 5: Evaluation of digestibility according to the LIP band standard

The digestibility of 20 cigarettes according to Comparative Examples and Examples was measured, and is shown in Table 5.

division	cigarette paper properties	LIP band standard	digestibility(%)
		(primary)height/depth, (secondary)height/depth
Example 1	-	7/28, 7/28	100%
Example 4	-	7/28, 7/28	100%
Comparative Example 4	Same as Example 1	7/17, 8/24	20%
Comparative Example 5	Example 4 same	7/17, 8/24	5%
Comparative Example 6	Same as Example 1	7/22, 7/22	30%
Comparative Example 7	Example 4 same	7/22, 7/22	30%

As shown in Table 5, it can be confirmed that, for both of the cigarette papers having the physical properties of Examples 1 and 4, excellent digestibility was exhibited only when the first and second LIP bands each had a width of 7 mm and a thickness of 28 μm. Considering that excellent digestibility is ensured when the LIP band specifications of Comparative Examples 4 to 7 are applied to cigarette paper to which cacao husk is not applied, as the cigarette paper contains cacao husk, the specifications of the LIP band are also It could be confirmed that a new design was required as in Fig.

Experimental Example 6: Color evaluation of cigarettes according to Example 1 and Comparative Example 1

After measuring the CIELAB color space data for 10 cigarettes according to Example 1 and Comparative Example 1, the average value was calculated and shown in Table 6.

Item	color difference value
	L	a	b
Example 1	68 ± 5.0	4.5 ± 3.0	9.0 ± 2.0
Comparative Example 1	47.37±3.0	9.73±2.5	16.23±2.5

As shown in Table 6, each of the 10 cigarettes according to Comparative Example 1 containing no cacao husk had an L* value of about 44 to 50, a* value of about 7 to 13, and b* value of about 13 to 19. was analyzed as In contrast, each of 10 cigarettes according to Example 1 containing cacao husk was analyzed to have an L* value of approximately 60 to 75, a* value of approximately 1.5 to 7.5, and b* value of approximately 7.0 to 11.0, Accordingly, it was confirmed that the cacao husk was not contained only in the husk particles 120aH shown in FIG. 1 in the cigarette paper, but permeated into the cigarette paper itself, causing changes in the color characteristics of the cigarette paper and other physical properties described above. can be checked

Comparative Example 8

The unflavored filter part of the cigarette according to Comparative Example 1 was removed, and a cigarette was prepared using a TJNS filter flavored with green apple and herb flavor.

Experimental Example 8: Smoking sensory evaluation of cigarettes according to Comparative Examples 1 and 8 and Example 1

In order to confirm the sensory characteristics of the cigarette employing the cigarette paper containing the cacao husk of the present invention, the fragrance intensity during smoking, the flavor satisfaction during smoking, and the smoking effect of the smoking articles according to Example 1, Comparative Example 1 and Comparative Example 8 Sensory evaluation was performed on the feeling of hitting, the feeling of taste during smoking, and the satisfaction after smoking.

The sensory characteristic evaluation was conducted for 20 evaluation panel members using the smoking articles of Example 1, Comparative Example 1, and Comparative Example 8, and a total of 8 points was the standard.

2 is a smoking sensory evaluation result for cigarettes prepared according to Example 1, Comparative Example 1, and Comparative Example 8 and stored at room temperature for 4 weeks.

Referring to FIG. 2 , it can be seen that the cigarette according to Comparative Example 8 employing a TJNS filter has higher flavor intensity and flavor satisfaction during smoking compared to the cigarette according to Comparative Example 1 using an unflavored filter. On the other hand, in Example 1 containing cacao husk, despite employing an unflavored filter, there was a significant increase in the value for the intensity of fragrance during smoking compared to Comparative Example 1, and in particular, the satisfaction with fragrance during smoking was measured by the TJNS filter. A higher score was found compared to Comparative Example 8 employing . Compared to Comparative Example 8, in which a strong menthol flavor is directly delivered to a smoker by treating the filter itself with hyangaek, the cacao flavor expressed from the cigarette paper by the combustion of the cigarette paper is subtly transmitted to the smoker, suggesting higher satisfaction.

There was no significant difference in the feeling of hitting during smoking, but the satisfaction after smoking slightly increased in Example 1 in which the cacao wrapper was employed, and it was confirmed that the taste during smoking also increased compared to Comparative Examples 1 and 8. This is presumed to be the effect of reforming the mainstream smoke examined in Experimental Example 2.

Those of ordinary skill in the art related to the present embodiment will understand that it can be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
