(S10) and coating the surface of the tipping paper with the OP coating solution (S20).

In the OP coating solution preparation step (S10), the OP ink and the OP adjuvant may be mixed in a weight ratio of approximately 1:2 to 2:1. For example, the doses of the OP ink and OP adjuvant may have a ratio of approximately 1:1, but are not limited thereto.

About 0.1% to 20% by weight of functional material may be added into the OP coating solution. Also, the weight ratio of the functional substance added in the OP coating solution to the OP ink (or OP auxiliary agent) is about 1:1.5 to 1:600, preferably about 1:2 to 1:500. Possible.

On the other hand, problems such as clogging of the printing cylinder, curling of the tipping paper, set-off of the printing ink, or falling off of the printing ink, which may occur in the process of coating the tipping paper with the OP coating solution containing the above functional substances, are eliminated. In order to solve the problem and ensure the effects of the above-mentioned functional substances, the functional substances may be added in different amounts in the OP coating solution depending on the type thereof. OP coating solution composition ratio is shown.

More specifically, when malic acid is added as the functional agent, the weight ratio of malic acid to OP ink (or OP adjuvant) added in the OP coating solution for chipping paper coating is about 1: 2 to 1:25, preferably about 1:7 to 1:12 (eg about 1:9.5). That is, in the case where the OP ink and the OP adjuvant are added at a ratio of 1:1, the OP coating solution contains about 0.1% to 20% malic acid, preferably about 2%. ~8%, more preferably about 4%-7% (eg, 5%) may be added. When grapefruit seed extract is added as the functional substance, the weight ratio of grapefruit seed extract and OP ink (or OP adjuvant) added in the OP coating solution for chipping paper coating is about 1:2. ~1:25, preferably about 1:3 to 1:10 (eg, about 1:6.6). That is, to give an example in which the OP ink and the OP adjuvant are introduced at a ratio of 1:1, the OP coating solution contains about 0.1% to 20% grapefruit seed extract, preferably about 0.1% to 20%. 3% to 11%, more preferably about 5% to 14% (eg 7%) may be added.

On the other hand, when the grapefruit seed extract is added as the functional substance, the tipping paper 130 coated with the functional substance contains ascorbic acid, tocopherol, and palmitic acid. , amino acids, glucose, naringin, and citral as active ingredients.

A mixture of malic acid and sucralose is preferably added as a functional substance in order to maximize the effect of reducing harmful bacteria. In this case, the weight ratio of said mixed material of malic acid and sucralose and OP ink (or OP adjuvant) added in OP coating solution for chipping paper coating is about 1:2 to 1:25, preferably , about 1:5 to 1:10 (eg, about 1:7.8). For example, when the OP ink and the OP adjuvant are added at a ratio of 1:1, the OP coating solution contains about 0.1% to 20% of the mixed material of malic acid and sucralose, Preferably, about 4%-9% (eg, about 6%) may be added.

More specifically, the weight ratio of malic acid and sucralose in the mixture of malic acid and sucralose is about 1:0.006-1:1.25, preferably about 1:0.1-1:0. can be three. That is, within the OP coating solution may be about 4%-15% malic acid and about 0.1%-5% sucralose (eg, about 5% malic acid and about 1% sucralose).

When the coating step (S20) is performed using the OP coating solution added with the above functional materials at the above composition ratio, it prevents the ink from falling off the surface of the tipping paper, preventing the tipping paper from sticking to the user's lips, etc. It is possible to ensure more advantageous sensory characteristics, reduction of harmful bacteria, and reduction of bad breath while faithfully ensuring the role inherent to the OP coating layer.

Experimental Example 1: Sensory Evaluation of Smoking by Coating with Functional Substances In order to confirm the effect of functional substance coating on improving sensory characteristics, in addition to the tobacco taste for each of the examples and comparative examples, the degree of satisfaction with taste and the degree of throat feeling were evaluated. A sensory evaluation for softness and off-flavour taste properties was performed. The sensory characteristics evaluation was performed once a day for 4 days at random on an evaluation panel of 30 people using the cigarettes manufactured according to the examples and comparative examples, and a total of 7 points was used as the standard. .

Table 2 shows the smoking sensory evaluation results of the smoking articles manufactured according to Comparative Example 1 and Examples 1-15.

As shown in Table 2, all of the cigarettes of Examples 1-15 exhibited superior taste satisfaction, throat softness and off-flavour taste characteristics compared to the cigarette of Comparative Example 1. Specifically, the characteristics of taste satisfaction generated when the user's mouth comes into contact with the tipping paper are as follows: Example 2 coated with malic acid; Example 5 coated with malic acid and sucralose; Example 7 coated, Example 11 coated with cinnamon oil, Example 13 coated with dark chocolate flavor and Example 15 coated with 5% sucralose were shown to be even better and It is shown that the softness property of the throat is even better in Example 2 coated with malic acid and Example 10 coated with cinnamon oil, and the effect of reducing offensive odor is Further superior in Example 2, Example 5 coated with malic acid and sucralose, Example 7 coated with sucralose, Example 9 coated with citric acid, and Example 15 coated with 5% sucralose It has been shown.

On the other hand, Example 2 coated with 5% malic acid and Example 5 coated with 5% malic acid and 0.9% sucralose are the best in all evaluation attributes compared to other examples. Thus, it was possible to confirm that the cigarettes according to Examples 2 and 5 were the most advantageous in terms of smoking sensation.

Experimental Example 2 Evaluation of Bad Breath Reduction Characteristics by Functional Substance Coating In order to confirm the effectiveness of the functional substance coating in reducing halitosis, halitosis samples of Examples 1 to 4 and Comparative Example 1 were collected and analyzed.

Halitosis sampling was performed on a total of five smokers four times for each example, and the interval between each time was set at 30 minutes. Halitosis collection was performed after each smoker closed his/her mouth for 2 minutes after smoking one cigarette, and the collected smoke was sampled in a 3 L Tedlar bag, followed by a pulsed flame photometric detector (PFPD). TD (thermal desorber)/GC (gas chromatography) analysis was performed.

The analysis was conducted to determine the main components that induce halitosis: Hydrogen Sulfide (H2S), Methyl Mercaptan (MM), Di-Methyl Sulfide (DMS) and Di-Methyl Di-Sulfide; DMDS), but DMDS is excluded from Table 3 below because it is difficult to derive meaningful results because it is detected at concentrations below the threshold level.

Table 3 presents the median value of each component for each example, the value obtained by dividing the median value by the threshold index (TI, Threshold Index), and the rate of change (%) for each component calculated thereby. there is

As shown in Table 3, all of the examples generally showed a decreasing trend of halitosis-inducing ingredients. Specifically, in the case of Examples 1 and 2 coated with malic acid, it was shown that there was substantially no effect of reducing the components of hydrogen sulfide and dimethyl sulfide, but a significant degree of methyl mercaptan component reduction was confirmed. We were able to.

When considering the general trend of higher odor generation contribution at lower threshold indices (TI for methyl mercaptan, hydrogen sulfide and dimethyl sulfide are 0.07 ppb, 0.4 ppb and 3.0 ppb, respectively), substantially Even in the case of malic acid coating, for which only the property of reducing methyl mercaptan has been confirmed, it is expected that a substantial effect of reducing halitosis can be expected.

On the other hand, in the cases of Examples 3 and 4, in which the grapefruit seed extract was coated, all halitosis-inducing components tended to decrease in general, and hydrogen sulfide and methyl mercaptan components in particular showed a very large reduction rate, and the chip It was confirmed that the paper coated with sucralose or grapefruit seed extract was most effective in reducing bad breath.

Experimental Example 3: Test result of reduction of harmful bacteria by coating with functional material In order to evaluate the effect of reducing harmful bacteria for each example, a reduction rate test of Streptococcus mutans present in the oral cavity was conducted according to the Korean standard test. The results were summarized in Table 4 below. FIG. 3 is a photograph showing the effect of reducing harmful bacteria in Comparative Example 1, Examples 2 and 4 with the naked eye, and FIGS. is a book.

On the other hand, in the test, the chip paper coated with each functional substance was allowed to absorb Streptococcus mutans for 18 hours, and then collected and cultured, and the reduction rate of Streptococcus mutans was measured against the control group not coated with the functional substance. did.

By cross-referencing Table 4 and FIGS. 3 to 7, it can be confirmed that all of Examples 2, 4, 5, 14 and 15 showed excellent reduction rates of Streptococcus mutans. Specifically, in the case of Example 2 coated with 5% malic acid, an effect of reducing Streptococcus mutans of 80% or more was shown, and in Example 4 coated with 7% grapefruit seed extract, about 50% Example 14 coated with 5% rosemary oil also showed a reduction of about 44%, and Example 15 coated with 5% sucralose also showed a reduction of about 65%. rate was shown. In particular, in the case of Example 5 coated with 5% malic acid and 0.9% sucralose, the reduction rate was about 98%, indicating excellent performance in terms of reducing harmful bacteria. rice field.

Based on the above results, it can be expected that the chipping paper coated with the above-described functional substance will have an effect of reducing harmful bacteria existing in the oral cavity when the user's lips are touched.

Those skilled in the art related to the embodiments will understand that the embodiments can be embodied in modified forms without departing from the essential characteristics described above. Accordingly, the disclosed method should be considered in an illustrative rather than a restrictive perspective.
