Description

[Technical field]

The present invention relates to a cigar wrapper to which vanilla flavor has been added, and to a smoking article containing such a wrapper, in particular, to a cigar wrapper to which vanilla flavor has been added and which is capable of reducing sidestream smoke odor, softening the taste of tobacco smoke and reducing its irritant properties, and to a smoking product containing such a wrapper.

[Prior Art]

Tobacco smoke produced during smoking can be divided into the main smoke stream entering the oral cavity through the tobacco filter, and the side smoke stream escaping into the atmosphere without passing through the filter. Components in the main smoke stream and side stream smoke that cause an unpleasant odor can form environmental sidestream smoke and negatively affect the smoker and those around him.

Thus, there is a need to develop a smoking material wrapper capable of reducing sidestream smoke odor and increasing smoking satisfaction, thereby distinguishing it from existing cigarettes.

[Disclosure of the invention]

[Technical problem]

The objective of the present invention is to develop specialized cigarette paper that reduces the odor of sidestream smoke and reduces the irritating properties of tobacco smoke, as well as the development of a smoking product containing such paper.

The objectives of the present description of the invention are not limited to the above object and will be fully apparent to those skilled in the field of technology to which the present invention relates based on the following disclosure of the invention.

[Technical solution]

In some embodiments, the present invention provides a smokable material wrapper that includes at least one vanilla-containing material: vanillin, ethyl vanillin and ethyl vanillin glucoside, and cigar fibers.

In this case, the weight of vanilla-containing material included in the smokable material wrapper may be from 0.5% to 10% of the total weight of the smokable material wrapper. Preferably, the weight of vanilla-containing material included in the smokable material wrapper may be from 1% to 5% of the total weight of the smokable material wrapper. More preferably, the weight of vanilla-containing material included in the smokable material wrapper may be from 2% to 4% of the total weight of the smokable material wrapper.

In this case, the mass of cigar fibers introduced into the composition of the smoking material wrapper can range from 5% to 80% of the total mass of the smoking material wrapper. Preferably, the weight of cigar fibers incorporated into the smokable material wrapper may range from 10% to 60% of the total weight of the smokable material wrapper. More preferably, the weight of cigar fibers incorporated into the smokable material wrapper may be from 20% to 40% of the total weight of the smokable material wrapper.

In some embodiments, the weight of vanilla-containing material included in the smokable material wrapper may depend on the weight of cigar fibers included in the smokable material wrapper.

The weight of vanilla-containing material added to the smokable material wrapper can be calculated by multiplying the reference factor by the value obtained by subtracting the reference constant from the weight of the cigar fibers. Here, the reference constant may be a real number in the range from 23 to 25, and the reference coefficient may be a real number in the range from 1 to 5.

Meanwhile, in the CIELAB color space, the smoking material wrapper may have an L* value in the range of 50 to 80, an a* value in the range of 1 to 15, and a b* value in the range of 20 to 30. Preferably, the L* value may be from 50 to 60, the a* value from 10 to 20, and the b* value from 20 to 30. Alternatively, the L* value may be from 65 to 80, the a* value from 1 to 5, and the b value * - from 20 to 30.

Thus, in some embodiments of the present invention, the smoking article comprises smokable material wrapped in a smokable material wrapper, a filter, the upper end of which is integrated with the smokable material and which is wrapped in the filter wrapper, and an end wrapper configured to wrap around the filter and, accordingly, at least a portion of the smoking material so that the smoking material and the filter are combined, with at least one vanilla-containing material: vanillin, ethyl vanillin and ethyl vanillin glucoside, and cigar fibers included in the wrapper of the smoking material.

[Beneficial Effects of the Invention]

Embodiments of the present invention, in which vanilla-containing material and cigar fibers are incorporated into the smokable material wrapper, can reduce or mask the sidestream tobacco odor with vanilla flavor to eliminate or reduce discomfort to the smoker or those around him.

In addition, the smoking material wrapper of the present invention can provide smoker-preferred organoleptic characteristics as well as the aforementioned sidestream smoke odor reduction effect.

In addition, by adding vanilla-containing material in an amount to provide sufficient flavor persistence and flavor to the wrapper of the smoking material of the present invention, the risk of discoloration of the cigarette paper can be minimized.

The protected scope of the invention is determined only by the scope of the claims. Reference designations refer to the same elements throughout the figures.

Unless otherwise specified, all terms (including technical or scientific) used herein have the meaning commonly used by those skilled in the art to which this disclosure pertains. Terms defined in generally accepted dictionaries should not be construed in an idealized or overly formalized sense unless expressly stated herein.

In addition, as used herein, the singular number is equivalent to the plural unless the context clearly indicates otherwise. The terms “comprises” and/or “comprising” as used herein do not exclude the possibility of the presence or addition of one or more elements, steps, operations and/or devices other than those mentioned above.

As used herein, “smoking article” refers to any device capable of generating an aerosol, such as tobacco (cigarette) and cigars. The smoking article may contain an aerosol generating material or substrate. In addition, the smoking article may include solid tobacco-based material, such as homogenized tobacco leaf, shredded tobacco, and homogenized tobacco. The smoking material may contain a volatile substance.

In FIG. 1 schematically illustrates the configuration of a smoking article in accordance with some embodiments of the present invention.

In the description, a case in which the smoking article 100 is a combustible type cigarette is disclosed as an example. However, in some cases, the smoking article 100 may also be a heater-type cigarette or the like used in conjunction with an aerosol generator (not shown in the figure), such as an electronic cigarette.

According to FIG. 1, the smoking article 100 may include a filter 110 wrapped with a filter wrapper 110a, a smokable material 120 wrapped with a smokable material wrapper 120a, and a wrapping paper 130 configured to combine the filter 110 and the smokable material 120.

The filter 110 may be located below the smokable material 120 and may be an area through which aerosol material generated in the smokable material 120 passes just before it is inhaled by the user.

Filter 110 can be made from various materials. For example, filter 110 may be a cellulose acetate filter. The filter 110 may be a cellulose acetate filter without fragrance material or a Transfer Jet Nozzle System (TJNS) filter containing fragrance material.

In some embodiments, the filter 110 may be a tubular structure with a cavity inside. The filter 110 may be manufactured by incorporating into it (eg, into a cavity) elements such as films or tubes made from the same or different materials.

The filter 110 of the present invention is illustrated as a monofilter consisting of a single filter, but the present invention is not limited to this embodiment. For example, to increase filtration efficiency, the filter 110 may, of course, be a dual filter comprising two acetate filters, a triple filter, or the like.

Additionally, although not shown in the figures, within the filter 110 there may be a crushable capsule (not shown in the figure) containing the flavor liquid infused therein and wrapped in film.

The smoking article filter 110 is located below the smoking material 120 and serves as a filter through which aerosol material generated in the smoking material 120 passes just before it is inhaled by the user.

The filter 110 may be wrapped in a filter wrap 110a. The filter wrapper 110a may be manufactured using greaseproof wrapping paper, and aluminum foil may be further applied to the inner surface of the filter wrapper 110a.

The smoking material 120 may contain raw tobacco leaves, homogenized tobacco leaves, or a mixture of tobacco leaves and homogenized tobacco leaves. The mixture may be introduced into the smoking material 120 in the form of leaf or shredded tobacco. The smoking material 120 may be in the form of an elongated rod of varying length, circumference, and diameter. In addition, smokable material 120 may contain at least one of the following aerosol-generating materials: glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the smoking material 120 may contain other additives, such as a flavoring agent, a wetting agent, and/or an acetate compound.

Smoking material 120 may be wrapped in a smokable material wrapper 120a. In this case, the amount of sidestream smoke generated, which may adversely affect the smoker and those around him, may be determined by the overall structure of the smoking article 100 or the mixture of tobacco leaves that may be introduced into the smoking material 120. In particular, the amount of sidestream smoke generated significantly influence the characteristics of the smoking material wrapper 120a surrounding the smoking material 120. For this reason, various attempts have been made to reduce the side smoke flow, in particular by making the smoking material wrapper 120a a double wrap or by changing the characteristics of the smoking material wrapper 120a, in particular, fiber composition, porosity , type of filler, distribution and number of particles. However, if the density of the smokable material wrapper 120a is increased compared to conventional cigarette paper in order to reduce sidestream smoke, the amount of fibers used may increase, which may increase the fiber odor and off-flavor during smoking. For this reason, the taste of tobacco smoke experienced by the smoker while smoking may be reduced, which limits the applicability of the above case to products.

Accordingly, to provide a specialized cigarette paper that softens the taste of tobacco smoke and reduces its irritating properties while reducing the tobacco odor caused by sidestream smoke, vanilla-containing material and cigar fibers can be incorporated into the smoking material wrapper 120a of the present invention.

Specifically, at least one vanilla-containing material: vanillin, ethyl vanillin, and ethyl vanillin glucoside may be incorporated into the smoking material wrapper 120a, and at the same time, cigar fibers extracted from cigars (cigar leaves) may be incorporated into the smoking material wrapper 120a. . In addition to vanilla-containing material and cigar fibers, cellulosic fibers such as bast fiber and wood pulp, inorganic fillers such as calcium carbonate, and combustion enhancers such as ammonium phosphate can be incorporated into the smoking material wrapper, among others.

Here, with respect to the persistence of the vanilla aroma during the storage period of the cigarettes, as well as the flammability, smoke flavor intensity and other characteristics of the cigarettes during smoking, the weight of the vanilla-containing material added to the smoking material wrapper 120a may be from 0. 5% to 10%, preferably 1% to 5%, more preferably 2% to 4%, based on the total weight of the smoking material wrapper.

As will be described in detail in the following experimental and other examples, if the amount of vanilla-containing material added is less than the above numerical range, the flavor intensity during smoking is reduced, making it difficult to significantly reduce the tobacco odor and ensure stable flavor persistence during cigarette storage. In addition, if the amount of vanilla-containing material added is greater than the above-mentioned numerical range, the flammability of the cigarettes is degraded to an extent resulting in an excessive increase in the number of puffs. Accordingly, the amount of nicotine transfer per puff decreases and, thereby, the intensity of taste sensations from tobacco smoke and satisfaction with the taste of tobacco smoke while smoking decreases. In addition, due to the lack of a harmonious combination of the aroma inherent in vanilla-containing material and the taste inherent in tobacco, overall satisfaction from smoking is also reduced.

At the same time, if only vanilla is added when making a wrapper for smoking material, then in addition to the advantage of the intensity of the aroma, problems such as a decrease in the intensity of the taste sensations from tobacco smoke, loss of aroma during storage of cigarettes and discoloration of the wrapper during storage may arise.

Considering such aspects, cigar fibers may be incorporated into the smokable material wrapper 120a according to the present invention along with vanilla-containing material.

Specifically, the weight of cigar fibers incorporated into the smoking material wrapper 120a may be from about 10% to 50%, preferably 20% to 40%, more preferably 25% to 35%, of the total weight of the smoking material wrapper 120a. material.

Incorporating cigar fibers in the above amounts together with vanilla-containing material into the smoking material wrapper 120a will solve the problem of discoloration of cigarettes, maintain satisfaction with the inherent taste of tobacco, and simultaneously provide a consistent reduction in tobacco odor through longevity and intensity of flavor. The increased severity of the above-mentioned effects associated with the addition of cigar fibers was confirmed, particularly in the case where vanilla-containing material was included in the composition of the wrapper 120a of the smoking material in an amount of about 3 wt.% or more.

In some embodiments, the weight of vanilla-containing material included in the smoking material wrapper 120a may depend on the weight of cigar fibers included in the smoking material wrapper 120a. That is, the amount of vanilla-containing material introduced may vary depending on the change in the amount of cigar fibers introduced. In other words, the amount of cigar fibers introduced may vary depending on the change in the amount of vanilla-containing material introduced.

Preferably, the amount of vanilla-containing material (or cigar fibers) may be proportional to the amount of cigar fibers (or vanilla-containing material). Preferably, as the amount of vanilla-containing material (or cigar fibers) increases, the amount of cigar fibers (or vanilla-containing material) may also increase.

In a specific example, the content of cigar fibers (or vanilla-containing material) may increase linearly with increasing amount of vanilla-containing material (or cigar fibers). More specifically, the weight of vanilla-containing material incorporated into the smoking material wrapper 120a can be calculated by multiplying the reference factor by the value obtained by subtracting the reference constant from the weight of the cigar fibers. That is, the relationship between the mass V of vanilla-containing material incorporated into the smoking material wrapper 120a and the mass C of cigar fibers incorporated into the smoking material wrapper 120a can be described by Formula 1.

[Formula 1]

V = cf×(C-ct)

In Formula 1, cf can denote the reference factor and ct can denote the reference constant. Preferably, the reference constant may be a real number in the range of about 23 to 25, and the reference coefficient may be a real number in the range of about 1 to 5.

If the amount of vanilla-containing material incorporated into the smoking material wrapper composition 120a is related to the amount of cigar fibers incorporated into the smoking material wrapper composition 120a in this manner, the quality of the main smoke stream and the side smoke stream can be further maximized while minimizing the degradation of the inherent flavor characteristics. tobacco smoke.

In addition, to minimize discoloration of the cigarette paper during the manufacturing process of the cigarettes, during the storage of the cigarettes, and during the marketing of the cigarettes at various temperatures and humidity levels, preferably in the CIELAB color space, a smokable material wrapper 120a that is incorporated with vanilla-containing material and cigar fibers may have an L* value in the range of 50 to 80, an a* value in the range of 1 to 15, and a b* value in the range of 20 to 30. More preferably, the L* value may be from about 50 to 60, the value a* is from about 10 to 20, and a b* value is from about 20 to 30. Alternatively, the L* value can be from about 65 to 80, the a* value is from about 1 to 5, and the b* value is about from 20 to 30.

Meanwhile, in order to improve the quality of the main smoke stream and the side smoke stream, provide differentiation from existing cigarettes, and preserve the tobacco smoke taste, flammability, extinguishing ability and processability of cigarettes when using the smoking material wrapper 120a according to the present invention, the smoking material wrapper 120a is preferably according to the present invention may contain a combustion additive in an amount of 1.0 to 1.5 wt.% and a filler in an amount of 12 to 21 wt.%.

In addition, to maintain the beneficial effects of the present invention under the above conditions of the smokable material wrapper 120a, the smokable material wrapper 120a may have a tensile strength in the range of about 0.08 kgf/mm to 0.10 mm kgf/mm and an elongation in the range approximately 0.5% to 1.0%.

In some embodiments, the smokable material wrapper 120a may have a dual structure. In particular, the smoking material wrapper 120a may include an inner wrapper (not shown) in contact with the smoking material 120 and surrounding the smoking material 120, and an outer wrapper in contact with the inner wrapper and surrounding an outer portion of the inner wrapper.

In this case, the inner wrapper and/or outer wrapper may be made of cigarette paper that is free of vanilla-containing material and cigar fibers, and the other wrapper may be made of cigarette paper that is composed of vanilla-containing material and cigar fibers.

Alternatively, the inner and/or outer wrapper may include vanilla-containing material and/or cigar fibers, and the other wrapper may contain cigar fibers and/or vanilla-containing material.

A smoking material wrapper having a double wrapping paper structure incorporating vanilla containing material and cigar fibers as described above may be more effective in terms of flavor persistence and reduction of sidestream smoke odor.

Here, in particular, the smokable material wrapper 120a may be a low-flammability NIP cigarette paper with one or more NIP stripes (not shown in the figure).

The filter 110 wrapped in the filter wrapper 110a and the smokable material 120 wrapped in the smokable material wrapper 120a may be wrapped together in the wrapping paper 130. Thus, the wrapping paper 130 may cover at least a portion (for example, a portion of the lower region ) the smoking material wrapper 120a and the outer periphery of the filter wrapper 110a. In other words, the filter 110 and at least a portion of the smoking material 120 may be wrapped in wrapping paper 130 and physically combined with each other. In some embodiments, the wrapping paper 130 may be made, specifically, using non-porous wrapping paper without being treated with a greaseproofing compound.

In particular, the wrapping paper 130 may contain a non-flammable material, thereby preventing the filter 110 from burning.

The configurations of the present invention and their advantages will be described in detail below with reference to examples and comparative examples. However, the examples are for illustrative purposes only, and the protected scope of the present invention is not limited to these examples.

Example 1

Cigarette paper wrapped around a cigarette portion containing shredded tobacco and manufactured to test examples was removed, and cigarette paper containing about 1 weight percent vanilla-containing material and about 30 wt% cigar fibers was wrapped around the shredded tobacco to make a cigarette. As the vanilla-containing material, a vanilla-containing material containing vanillin and ethylvanillin in a ratio of about 1:1 was used, and fibers extracted from the middle lobes of cigar leaves were used as cigar fibers.

Example 2

A cigarette was manufactured identical to that of Example 1 except that the cigarette paper contained approximately 3 weight percent vanilla-containing material.

Comparative example 1

A cigarette was produced identical to the cigarette according to Example 1, except that the cigarette paper did not contain vanilla-containing material.

As shown in Tables 1-3, physical properties that render it unmanufacturable were not observed in any of the Comparative Examples and Examples; in addition, no deterioration in physical properties was observed during the storage period for each condition.

Comparative example 2

A cigarette was produced identical to the cigarette according to Example 1, except that the cigarette paper did not contain cigar fibers.

Experimental Example 2: Storage Stability of Vanilla Cigar Wrappers - Discoloration Evaluation

To evaluate discoloration during the storage period, CIELAB color space data were measured for cigarette paper according to each example, and the measurement results are summarized in Table 4.

According to Table 4, in the case of Comparative Example 1, a change in color difference value of ±16.0 was observed during the storage period, and the ΔE value was calculated to be approximately equal to 17.5 under severe conditions. In Example 1, the change in color difference value was observed to be ±3.0, and the ΔE value for severe conditions was calculated to be approximately 2.3. Therefore, considering that, in general, a consumer can recognize a color change only when the ΔE value is 3 or more, it was confirmed that the problem of discoloration does not occur in the manufacture of cigarettes according to Example 1. Results of Comparative Example 1 in which the amount of containing vanilla material in the cigarette paper was the same as Example 1, but the cigarette paper did not contain cigar fibers, show that in Example 1, the amount of change in the color difference value was smaller and the ΔE value was lower than in Comparative Example 1. Next, in the case of Example 1, as indicators different from the CIELAB color space data according to Table 4, the whiteness and opacity characteristics were also confirmed to be superior compared to Comparative Example 1. Specifically, in Comparative Example 1, the whiteness changed by about -8.9 during the storage period % (about -12.4% in hard conditions), and opacity by about 7.4% (about 8.7% in hard conditions), but in example 1 even in hard conditions the whiteness changes (about 2% in hard conditions ) and opacity (approximately 3% under severe conditions) were found to be less than at constant temperature and humidity in Comparative Example 1. Thus, the amount of vanilla-containing material and cigar fibers corresponding to the above examples was found to be beneficial in minimizing discoloration .

In Example 2, the change in color difference value was observed to be ±6.0, and the ΔE value was calculated to be approximately 1.6 at constant temperature and humidity and approximately 6.7 for harsh conditions. Thus, it was confirmed that the problem of discoloration does not occur during the normal storage and distribution period of cigarettes manufactured in accordance with Example 2.

Experimental Example 3: Evaluating Processability of Vanilla-Containing Cigar Wrappers

To evaluate the manufacturability during manufacture of a cigarette onto which a vanilla-containing cigar wrapper is mounted, the possible production speed, adhesive properties, the presence of cigarette paper breaks, the presence of adhesive contamination, and the quenching speed of the cigarette paper were evaluated according to each example, and the evaluation results were tabulated 5.

The data in Table 5 shows that there is no significant difference in the speed and processability of cigarettes depending on the addition of vanilla-containing material.

Experimental Example 4: Evaluation of Smoke Components

To analyze the components of the main and side smoke flows for each example, samples were taken from the main and side smoke flows generated during smoking of each cigarette. For each sample, three samples were taken, each containing 70 ml of sidestream smoke and 20 ml of main stream smoke. The results of the component analysis as the average of the three groups of results are summarized in Tables 6 and 7. The cigarettes were tested in accordance with Health Canada smoking conditions using an automatic smoking device in a designated smoking area at approximately 20°C and humidity. about 62.5%.

According to Table 6, in both examples, the detection values of the main smoke components such as tar, nicotine and carbon monoxide were close to those of the comparative example, and the amount of vanillin and ethylvanillin in the main smoke stream increased slightly in both examples compared with the comparative example. The results of the analysis of the sidestream smoke components in both examples indicated that the increase in the amount of vanilla-containing component was greater than the increase in the amount of vanilla-containing component in the main smoke stream. Specifically, in Example 2, in which the amount of the vanilla-containing component was 3%, the amount of vanillin increased by 30% or more, and the amount of ethylvanillin increased by 80% or more compared with Comparative Example 1; Thus, the intensity of vanilla aroma in the side smoke stream was confirmed.

According to Table 7, in both examples, the amount of expressed vanilla-containing component generally increased compared to the comparative example, and the loss of vanilla-containing component during the storage period of the cigarettes also generally decreased. Specifically, in the case of Example 2, the absolute amount of expressed aroma increased, and the decrease ratio of the expressed amount of vanilla-containing component in the main and side smoke streams during the storage period decreased markedly compared with Comparative Example 1.

Experimental Example 5: Evaluation of Tobacco Odor Reduction

For each example, the amounts of nicotine, 3-ethylpyridine, 3-ethenylpyridine, and pyridine responsible for tobacco odor were analyzed for each example to test for the reduction of sidestream smoke odor, finger tobacco odor, and halitosis, and the results of the analyzes were summarized in Table 8. The cigarettes were tested in accordance with Health Canada smoking conditions using a sidestream smoking device in a designated smoking area at a temperature of approximately 20°C and an air humidity of approximately 62.5%, and the analysis was carried out by solid phase microextraction followed by gas chromatography and mass spectrometry (SPME-GC/MS) of the collected sidestream smoke.

According to Table 8, the tobacco odor values decreased in both examples, and, accordingly, in both examples, a decrease in the smoke odor in the side smoke flow can be expected. In particular, it can be seen that in Example 2, in which the amount of added vanilla-containing component was about 3%, the effect of reducing the content of 3-ethylpyridine, 3-ethenylpyridine and pyridine, which can cause unpleasant odor such as tobacco odor and burning odor, was significant, which further increased the effectiveness of reducing smoke odor in the side smoke flow.

Experimental Example 6: Sensory Smoking Evaluation of a Vanilla Cigar Wrapper Product

To confirm the effect of improving the organoleptic characteristics of a cigar wrapper containing vanilla using examples, an organoleptic assessment was performed of the level of external aroma of the cigarette part, the intensity of the taste sensations from tobacco smoke, irritation, the general taste of tobacco, off-flavor, aroma of the side smoke stream, unpleasant odor of the side smoke stream and the degree receiving side smoke flow. The organoleptic evaluation was carried out by a group of sixteen experts who assessed each of the cigarettes produced according to the examples on a seven-point scale. Table 9 shows the results of the organoleptic assessment of the main smoke flow, and Table 10 shows the organoleptic assessment of the side smoke flow.

According to Table 9, in Example 1, in which vanilla-containing material was added at approximately 1%, despite some differences depending on storage period and/or conditions, the level of external aroma generally increased, irritation and off-flavor showed a decreasing trend , and the intensity of the taste sensations from tobacco smoke and the overall taste of tobacco also generally increased, although relatively less noticeably. In Example 2, in which the amount of vanilla-containing material introduced was approximately 3%, all the organoleptic characteristics of the main smoke stream, except for the intensity of the taste sensation of tobacco smoke, were noticeably increased compared with Comparative Example 1 and Example 1. Thus, the quality improvement effect the main smoke flow was greatest in example 2.

According to Table 10, in both Examples 1 and 2, the intensity of the side smoke stream aroma and the acceptance rate of the side smoke stream increased, and the unpleasant odor of the side smoke stream decreased compared with Comparative Example 1. From the results shown in Tables 9 and 10, it is clear that The effect of improving the quality of the side smoke stream was greater than the effect of improving the quality of the main smoke stream in Example 1, while in Example 2 both the effect of improving the quality of the main smoke stream and the effect of improving the quality of the side smoke stream were significant. However, although not disclosed in the above examples and experimental examples, if the amount of vanilla-containing material included in the wrapper of the smoking material is increased to 5% or more, other organoleptic characteristics must be further considered in addition to the problem of discoloration and reduction of tobacco odor.

Example 3

A cigarette was manufactured identical to that of Example 1 except that the cigarette paper contained approximately 5 weight percent vanilla-containing material.

Example 4

A cigarette was manufactured identical to that of Example 3 except that the cigarette paper contained approximately 27 weight percent cigar fibers.

Example 5

A cigarette was manufactured identical to that of Example 3 except that the cigarette paper contained approximately 33 weight percent cigar fibers.

Experimental Example 7: Storage Stability of Vanilla-Containing Cigar Wrappers - Discoloration Evaluation

To evaluate discoloration as a function of the amount of vanilla-containing material and cigar fibers added, CIELAB color space data were measured for cigarette paper according to Examples 3-5, and the measurement results are summarized in Table 11.

According to Table 11, in the case of Example 3, in which the cigar fiber content was approximately 30%, the change in color difference value was observed to be ±8.0 during the storage period, and the ΔE value was calculated to be approximately equal to 8.7 for severe conditions . In the case of Example 4, in which the cigar fiber content was approximately 27%, a change in color difference value of ±11.0 was observed during the storage period, and the ΔE value was calculated to be approximately equal to 12.2 for severe conditions. In the case of Example 5, in which the cigar fiber content was approximately 33%, a change in color difference value of ±5.0 was observed during the storage period, and the ΔE value was calculated to be approximately equal to 5.6 for severe conditions. The results of discoloration evaluation of the above examples and cigarettes containing more than 5% vanilla-containing material confirmed that, otherwise identical conditions, the amount of change in color difference value generally increases when more than 5% vanilla-containing material is added, and that in order to reduce the degree of discoloration, the amount of cigar material added fibers should be adjusted accordingly according to changes in the amount of vanilla-containing material introduced. More specifically, to eliminate or reduce discoloration, it is preferable to increase the amount of cigar fibers in accordance with the increase in the amount of vanilla-containing material.

Experimental Example 8: Sensory Smoking Evaluation of a Vanilla Cigar Wrapper Product

To confirm the effect of improving the organoleptic characteristics depending on the amount of vanilla-containing material and cigar fibers introduced, the organoleptic characteristics of the main smoke stream and the organoleptic characteristics of the side smoke stream were evaluated for each example, and the evaluation results were summarized in Table 12. The sensory evaluation was carried out by a group of eleven experts using cigarettes according to each example, which were stored for sixteen weeks under harsh conditions, on a seven-point scale.

[Table 12]

Classification Organoleptic assessment of the main smoke flow Organoleptic evaluation of side smoke flow External cigarette aroma level Intensity of taste sensations from tobacco smoke Irritation General taste of tobacco Foreign taste Side smoke flow aroma intensity Unpleasant odor from side smoke stream Degree of side smoke flow reception Example 3 4.8 4.7 4.5 4.8 4.7 5.5 4.2 5.3 4.7 4.5 4.6 4.9 4.7 5.4 4.4 5.1 Example 4 4.5 4.1 4.6 4.6 5.1 5.2 4.3 5.1 4.6 4.2 4.4 4.5 5.2 5.4 4.5 5.0 Example 5 4.7 5.3 4.3 4.9 4.1 5.3 4.6 5.4 4.9 5.1 4.5 5.0 4.3 5.6 4.5 5.4

According to Table 12, based on cigar fiber content, no significant differences were found with respect to the level of external cigarette aroma, irritation, sidestream aroma intensity, sidestream odour, and sidestream acceptance rate, but differences were found between examples with respect to the intensity of taste sensations from tobacco smoke, the general taste of tobacco and foreign taste. Specifically, in Example 4, in which cigar fiber was added at an amount of approximately 27%, the smoke flavor intensity and overall tobacco flavor were slightly reduced and the off-flavor was slightly increased compared to Example 3. On the other hand, in Example 5 , in which cigar fibers were added in an amount of approximately 33%, the smoke flavor intensity and overall tobacco flavor were increased and the off-flavor was reduced compared to Examples 3 and 4. The above discoloration and sensory evaluation results indicate that when containing vanilla material in an amount of approximately 5%, the most beneficial effect is provided by the introduction of cigar fibers in an amount of approximately 33%. That is, if the amount of vanilla-containing material introduced is changed, to further enhance the above-described effects of the present invention, it will also be advantageous to change the amount of cigar fibers introduced. One skilled in the art, when considering the above embodiments, will understand that the present invention may be practiced in modified forms without departing from the essential features of the above disclosure. Therefore, the methods disclosed herein should be considered illustrative and not restrictive.
