Description

Smoking article with improved flavor retention {SMOKING ARTICLE WITH IMPROVED FLAVOR PRESERVATION}

The present disclosure relates to smoking articles with improved flavor retention. More particularly, it relates to a flavoring agent designed to prevent deterioration of flavor retention of a flavoring agent added to a smoking article over time, a smoking article comprising the same, and a method for preparing the flavoring agent.

Kretek cigarettes are clove-flavored cigarettes and are a popular smoking article in Indonesia. The ingredient that plays an important role in enhancing the taste and flavor of Cretec tobacco is eugenol, which also refers to clove extract (e.g. clove oil) itself containing eugenol.

In order to enhance the taste and flavor of Cretec cigarettes, it is important to increase the amount of eugenol transferred during smoking. For example, a method of directly spraying a clove extract onto a tobacco raw material, a method of adding a liquid clove extract in a flavor capsule, and the like have been proposed.

However, the proposed methods do not sufficiently consider the volatility of the clove extract (e.g. eugenol), causing a problem that the clove extract is lost over time. That is, according to the proposed methods, the clove extract added to the tobacco volatilizes and decreases over time, and the taste and flavor of the tobacco gradually deteriorate.

Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

According to various embodiments of the present disclosure, a smoking article having improved flavor retention may be provided. More specifically, there may be provided a smoking article with improved flavor retention of the volatile flavor material, for which the volatile flavor material may be prepared into flavor granules having a porous structure and added to the smoking article. The reason for using the porous flavor granules is that the porous structure and solid state are very effective in suppressing the volatility of flavor substances. Hereinafter, for convenience of understanding, it is assumed that the volatile flavor material is a clove extract, unless otherwise stated, and the description is continued. However, the technical scope of the present disclosure is not limited thereto, and the embodiments described below may be applied to any flavor material having volatility without substantially changing the technical idea.

Since the location at which the flavor granules are added may vary based on factors such as the diameter of the flavor granules and the detailed structure of the smoking article, smoking articles with improved flavor preservation can be designed and manufactured in various forms.

Before describing various types of smoking articles, for convenience of understanding, exemplary smoking articles that may be referred to in various embodiments of the present disclosure will be briefly described with reference to FIG. 1 .

1 shows an exemplary smoking article 1 that may be referenced in various embodiments of the present disclosure.

As shown in FIG. 1 , a smoking article 1 may include a filter part 11 and a smoking material part 12 . However, only the components related to the embodiment of the present disclosure are illustrated in FIG. 1 . Accordingly, one of ordinary skill in the art to which the present disclosure pertains can know that other general-purpose components other than those shown in FIG. 1 may be further included.

The filter unit 11 may include a filter plug made of a filter material and a filter wrapper that wraps the filter plug, and may be connected to at least one of both ends of the smoking material unit 12 . For example, the filter unit 11 and the smoking material unit 12 may have a cylindrical shape and are aligned in the longitudinal axis direction, and the filter unit 11 may be located downstream of the smoking material unit 12 . Also, the filter unit 11 and the smoking material unit 12 may be connected by a tipping wrapper. The tipping wrapper may connect at least a portion of the filter unit 11 and at least a portion of the smoking material unit 12 together to connect the filter unit 11 and the smoking material unit 12 . When the filter element 11 is located at the downstream end of the smoking article 1 , the filter element 11 can also serve as a mouthpiece.

The filter material may include, but is not limited to, cellulose acetate fibers. In some embodiments, the filter material may further comprise at least one filter material well known in the art. For example, the filter material may further comprise an adsorbent comprising carbon, activated carbon, and the like.

In some embodiments, a plasticizer may be added during the manufacturing process of the filter plug, and a clove extract may be used as a plasticizer. The inventors of the present disclosure conducted continuous research to develop an eco-friendly/natural plasticizer, and as a result of the study, it was surprisingly confirmed that the clove extract has the property of plasticizing cellulose acetate tow. In addition, the present inventors could also confirm that the filter plug to which the clove extract is added has excellent biodegradability compared to the case in which an artificial plasticizer (e.g. triacetin) is added. It can be understood that the biodegradability improvement of this filter is due to the fact that the clove extract is a natural material extracted from the clove plant. According to this embodiment, by using the clove extract as a plasticizer, a filter having excellent biodegradability can be manufactured. Furthermore, the amount of eugenol transfer is increased, so that the clove scent in smoking articles can be further enhanced when smoking.

The filter unit 11 may be formed of a single filter or multiple filters. In addition, the filter unit 11 may include a cavity formed by multiple filters, and a capsule containing a flavor material may be located inside (eg, a cavity) of the filter unit 11 . As such, the detailed configuration or implementation form of the filter unit 11 may be modified according to embodiments, and thus the technical scope of the present disclosure is not limited by the detailed configuration or implementation form of the filter unit 11 . For various examples of the detailed configuration of the filter unit 11, reference will be made to the drawings of FIGS. 2 to 4 .

Next, the smoking material unit 12 may include a smoking material and a wrapper that wraps the smoking material. The smoking material unit 12 may have a cylindrical shape, but the technical scope of the present disclosure is not limited thereto.

The smoking material may include various types of materials that generate smoke and/or aerosols or are used for smoking. The smoker generates smoke and/or aerosol through the smoking article, and the generated smoke and/or aerosol may be inhaled by the smoker through the filter unit 11 .

The smoking material may comprise, for example, tobacco material. Tobacco material may include, for example, tobacco leaf pieces, tobacco stems or materials processed therefrom, and the like. As a more specific example, the tobacco material may include pulverized tobacco leaves, pulverized reconstituted tobacco, expanded cornflower, expanded stems and leaflets, and the like.

In some embodiments, the smoking material may further include additives such as wetting agents, flavoring agents and/or organic acids. For example, the wetting agent may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Wetting agents can keep moisture in the tobacco material at an appropriate level, softening its intrinsic taste, and enriching the amount of atomization. In addition, flavoring agents include, for example, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil. , vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander, clove extract (or clove substance) or coffee can do.

In some embodiments, the smoking material may comprise a clove material. For example, the clove material may include clove powder, clove plant fragments, etc. produced by grinding or processing clove plants (e.g. clove leaves). In such a case, since a crackling sound (or kritek-critek) is generated during smoking, an auditory effect is added to the clove scent and flavor, thereby providing a more improved smoking experience to the smoker. .

Also, in some embodiments, polysaccharide materials (eg, cellulose, starch, glycogen, etc.) may be added to the smoking material portion 52 to enhance the sound generating effect of the smoking article 50 . The surprising fact that a polysaccharide material generates sound when it is burned was revealed during the course of continuous research. Through experiments, the present inventors confirmed that a certain sound is generated as the crystal structure is broken when the polysaccharide material is burned. Accordingly, according to the present embodiment, the polysaccharide material added to the smoking material part 52 acts as a sound generating factor during smoking, so that the sound generating effect of the smoking article 50 may be increased.

In the above-described embodiment, the polysaccharide material may be added in place of the clove material, or may be added together with the clove material. The polysaccharide material may be processed into, for example, particles, sheets and elongated objects (e.g. toothpick shapes) and added to the smoking material portion 52, but the technical scope of the present disclosure is not limited thereto. . As a more specific example, the polysaccharide material in the form of particles may be added to the smoking material portion 52 or a wrapper that wraps the smoking material. As another example, the polysaccharide material in the form of a sheet may be added to the smoking material portion 52 together with the tobacco sheet or disposed on the wrapper. As another example, the polysaccharide material in the form of an elongated object may be added to the smoking material portion 52 in a engraved or uncut state. According to the present embodiment, the sound generation effect of the smoking article 50 is increased, so that a more improved smoking experience can be provided to the smoker. Furthermore, since polysaccharide materials (e.g. starch) are generally very inexpensive, the material cost of the smoking article 50 can be reduced. Furthermore, since the polysaccharide material (e.g. starch) is a safe material that humans ingest as food, the safety of the smoking article 50 is ensured, so that the cost of the safety test can be greatly reduced.

Meanwhile, according to various embodiments of the present disclosure, a clove extract (e.g. clove oil) including a eugenol component may be added to a smoking article (e.g. 1, etc.) as a flavoring agent to add clove flavor and flavor. At this time, in order to improve the flavor preservation of the clove extract, a flavoring agent may be added to the smoking article in the form of solidified granules (e.g. 1, etc.) may vary based on the factors of Hereinafter, various embodiments related thereto will be described with reference to the drawings below FIG. 2 .

2 is a view for explaining the smoking article 2 according to the first embodiment of the present disclosure. Hereinafter, for clarity of the specification, a description of the content overlapping with that described above will be omitted, and the description of the components of the smoking article 2 and the like will be referred to with reference to the description of FIG. 1 .

As shown in FIG. 2 , the overall configuration of the smoking article 2 is similar to the smoking article 1 illustrated in FIG. 1 . That is, the smoking article 2 may also include a filter part 21 and a smoking material part 22 .

In this embodiment, flavor granules 23 including clove extract may be added to the filter unit 21 . This is because, by adding the flavor granules 23 to the filter unit 21 close to the smoker's mouth side, the clove scent and flavor can be delivered more directly to the smoker.

As shown in FIG. 2 , the flavor granules 23 may be manufactured to have a porous structure. The porous structure has an effect of preventing volatilization of the internal material due to its structural characteristics. Accordingly, when the flavor granules 23 are manufactured in a porous structure, flavor retention is improved, and flavor development can be maintained even over time. A method of preparing the flavor granules 23 having a porous structure will be described later with reference to FIG. 7 .

In some embodiments, the batch distribution of the flavor granules 23 added to the filter unit 21 may vary according to embodiments. For example, the flavor granules 23 may be arranged to be evenly distributed in the filter unit 21 . That is, the flavor granules 23 disposed between the filter materials (e.g. cellulose acetate fibers) may be evenly distributed. As another example, the flavor granules 23 may be disposed to be more distributed on the downstream end (ie, in the bending direction) side of the filter unit 21 . This is because the more the flavor granules 23 are distributed on the downstream end side, the more directly the scent diffusing effect can be delivered to the smoker. As another example, the flavor granules 23 may be disposed to be more distributed on the upstream end side of the filter unit 21 .

The diameter of the flavor granules 23 added to the filter unit 21 may be, for example, about 0.1 mm to about 2.0 mm. Preferably, the diameter of the flavor granules 23 may be from about 0.2 mm to about 1.8 mm, more preferably from about 0.3 mm to about 1.6 mm, from about 0.4 mm to about 1.4 mm, from about 0.4 mm to about 1.2 mm. or from about 0.5 mm to about 1.0 mm.

It may be preferable that the diameter of the flavor granules 23 added to the filter unit 21 is greater than or equal to a certain size (e.g. about 0.4 mm). This means that when flavor granules of a very fine size are added to the filter material, dust is generated in the filter. Alternatively, flavor granules may adsorb to the filter and affect the filter's performance. Alternatively, this is because the fine-sized flavor granules 23 block the passage inside the filter to increase suction resistance and reduce the amount of atomization.

In addition, it may be preferable that the diameter of the flavor granules 23 is less than a certain size (e.g. about 1.4 mm), which increases suction resistance even if the diameter of the flavor granules 23 becomes too large, which negatively affects the smoker's comfortable smoking experience. This is because it can reduce the amount of atomization.

The diameter of the flavor granules 23 may be measured by checking the particle size passed through a scanning electron microscope (SEM) analysis or a sieve vibrator (sieve shaker). However, the method for measuring the diameter of the flavor granules 23 is not limited thereto.

So far, the smoking article 2 according to the first embodiment of the present disclosure has been described. As described above, as the flavor granules 23 including the clove extract are added to the filter unit 21 , the taste and flavor of the smoking article 2 can be maintained for a long time. In addition, since the eugenol component contained in the clove extract will be released through the flavor granules 23 , the amount of eugenol transferred during smoking may be increased, and thus the clove flavor and flavor of the smoking article 2 will be improved. can

3 is a view for explaining a smoking article 3 according to a second embodiment of the present disclosure.

As shown in FIG. 3 , the smoking article 3 may include filter parts 31 , 32 composed of multiple filters. That is, the smoking article 3 may include a first filter unit 31 , a second filter unit 32 , and a smoking material unit 33 . Although FIG. 3 illustrates that the filter parts 31 and 32 of the smoking article 3 are configured as double filters as an example, this is only for convenience of understanding, and the number of filters may vary.

In this embodiment, flavor granules 34 may be added to at least one of the first filter unit 31 and the second filter unit 32 .

For example, as illustrated in FIG. 3 , flavor granules 34 may be added to the first filter part 31 located at the downstream end of the smoking article 3 . In this case, the fragrance effect of the clove extract may be more directly transmitted to the smoker.

As another example, the flavor granules 34 may be added to the second filter unit 32 .

As another example, the flavor granules 34 may be added to both the first filter unit 31 and the second filter unit 32 . In this case, the amount of flavor granules 34 added to the first filter unit 31 may be the same as or greater than that of the second filter unit 32 . In order to improve the transferability of the clove extract fragrance effect, a larger amount of flavor granules 34 may be added to the first filter unit 31 .

So far, the smoking article 3 according to the second embodiment of the present disclosure has been described with reference to FIG. 3 . As described above, when the smoking article 3 includes multiple filters, the flavor granules 34 may be selectively added to the at least one filter unit 31 , 32 .

4 is a view for explaining a smoking article 4 according to a third embodiment of the present disclosure.

As shown in FIG. 4 , the smoking article 4 may include a first filter portion 41 , a second filter portion 42 , a cavity 43 , and a smoking material portion 44 . The cavity 43 may be formed between the first filter unit 41 and the second filter unit 43 .

In this embodiment, flavor granules 45 may be added inside the cavity 43 . By doing so, it can be prevented in advance that the addition of the flavor granules 45 affects the performance of the filter parts 41 and 42 . In addition, by adding the flavor granules 45 to be densely packed inside the cavity 43 , the scent diffusing effect of the flavor granules 45 may be enhanced.

In some embodiments, the lengths of the first filter unit 41 and the second filter unit 42 may be different from each other. For example, the length of the first filter part 41 located on the downstream side of the smoking article 4 may be shorter than the length of the second filter part 42 . By doing so, the cavity 43 is positioned closer to the bent side, and the clove scent and flavor can be more strongly transmitted to the smoker.

So far, the smoking article 4 according to the third embodiment of the present disclosure has been described with reference to FIG. 4 . As described above, since the flavor granules 45 are concentrated inside the cavity 43 , the taste and flavor of the smoking article 4 may be further enhanced. When the clove extract is included in the flavor granules 45, the expression of clove flavor can be greatly improved during smoking.

5 is a view for explaining a smoking article 5 according to a fourth embodiment of the present disclosure.

As shown in FIG. 5 , the smoking article 5 may include a filter portion 51 and a smoking material portion 52 . As described above, the filter unit 51 may include multiple filters.

In this embodiment, flavor granules 53 may be added to the smoking material unit 52 instead of the filter unit 51 . By doing so, it can be prevented that the flavor granules 53 affect the filter performance.

The diameter of the flavor granules 53 added to the smoking material part 52 may be the same as or different from each other. In addition, the diameter of the flavor granules 53 may be, for example, about 0.8 mm or less, and preferably about 0.7 mm or about 0.6 mm or less. More preferably, the diameter of the flavor granules 53 may be about 0.4 mm or 0.3 mm or less, which may increase the resistance to suction or negatively affect the burning rate of the smoking material when the size of the flavor granules 53 increases. because there is

In addition, the diameter of the flavor granules 53 may be, for example, about 0.01 mm or about 0.05 mm or more, and preferably about 0.1 mm or more. This is because the smaller the size of the flavor granules 53, the lower the flavor development, and the cost and difficulty of manufacturing the granules increase.

So far, the smoking article 5 according to the fourth embodiment of the present disclosure has been described with reference to FIG. 5 . As described above, by adding the flavor granules 53 to the smoking material portion 52 , the taste and flavor of the smoking article 5 can be enhanced without adversely affecting the filter performance. If clove extract is included in the flavor granules 53, the expression of clove flavor can be greatly improved during smoking.

6 is a view for explaining a smoking article 6 according to a fifth embodiment of the present disclosure.

As shown in FIG. 5 , the smoking article 6 may include a filter portion 61 and a smoking material portion 62 . As described above, the filter unit 61 may be formed of multiple filters.

In addition, the filter unit 61 may include a filter wrapper 63 that wraps a filter plug made of a filter material. Of course, the smoking article 6 may further include, in addition to the filter wrapper 63 , a wrapper for wrapping a smoking material, a tipping wrapper, and the like.

In this embodiment, flavor granules 64 may be added to at least one wrapper included in smoking article 6 . In this case, the taste and flavor of the smoking article 6 can be enhanced without affecting the suction resistance or filter performance of the smoking article 6 .

In some embodiments, flavor granules 65 may be added to a separate sheet or film, and the sheet or film may be attached around a wrapper (e.g. 63).

Further, in some embodiments, the at least one wrapper, the sheet or the film may be subjected to a flavoring treatment. For example, a flavoring treatment may be performed with clove extract (e.g. eugenol), in which case the clove flavor of the smoking article 6 may be further enhanced.

So far, the smoking article 6 according to the fifth embodiment of the present disclosure has been described with reference to FIG. 6 . As described above, by adding the flavor granules 64 to the wrapper, the negative impact of the flavor granules 64 on filter performance or suction resistance can be prevented, and the taste and flavor of the smoking article 6 can be can be promoted When the clove extract is included in the flavor granules 64, the expression of clove flavor can be greatly improved during smoking.

Meanwhile, the technical ideas contained in the first to fifth embodiments described so far may be combined in various forms. For example, in order to further increase the amount of eugenol transfer, flavor granules (e.g. 23, 34, 45, 53, 64) are combined with a filter unit (e.g. 11, 21, 31, 32, 41, 42, 51, 61) and It may be added to both sides of the smoking material portions 12, 22, 33, 44, 52, 62. In this case, flavor granules (e.g. 23, 34, 45, 53, 64) having a diameter greater than or equal to the reference value are added to the filter unit (e.g. 11, 21, 31, 32, 41, 42, 51, 61), and flavor less than or equal to the reference value Granules (e.g. 23, 34, 45, 53, 64) may be added to the smoking material section 12, 22, 33, 44, 52, 62. The reference value may be variously set, but preferably about 0.4 mm.

Up to now, smoking articles 2 to 6 having improved flavor preservation according to various embodiments of the present disclosure have been described with reference to FIGS. 2 to 6 . Hereinafter, a method for preparing flavor granules (e.g. 23, 34, 45, 53) having a porous structure will be described.

7 is a view for explaining a method for manufacturing flavor granules according to some embodiments of the present disclosure.

7, the flavor granules 77 may be manufactured through a top spray-based primary manufacturing process 73 and a rotary spray-based secondary manufacturing process 76. there is. Top spray and rotary spray methods are one of the fluidized bed granulation manufacturing techniques. Those skilled in the art will be able to clearly understand the operating principle of each method, and detailed descriptions of each method will be omitted. Hereinafter, each manufacturing process will be described.

In the primary manufacturing process 73 , the flavor material including the clove extract 71 may form the flavor granules 74 of an amorphous (eg, a spherical surface with a rough surface) through a top spray method. A binder 72 may be added during the manufacturing process to facilitate the formation of granules 74 . For example, the binder 72 may include at least one of hydroxypropyl methylcellulose (hereinafter, “HPMC”) and gum.

In the secondary manufacturing process 75, the shape and surface properties of the flavor granules 74 may be improved through the rotary spray method. The flavor granules 74 formed by the top spray method generally have weak hardness and have irregular and irregular surface characteristics (e.g., rough and non-uniform surface), so they may be easily broken or finely divided by friction. The secondary manufacturing process 75 may be understood as a process of improving the physical properties of the flavor granules 74 by smooth coating the surface of the flavor granules 74 . In order to increase the hardness of the flavor granules 74 and to easily coat the surface, a binder 75 may be added during the manufacturing process. The binder 75 may include, for example, at least one of starch-type materials. The flavor granules 77 having a smooth surface and a spherical shape may be manufactured through the secondary manufacturing process 76 .

Meanwhile, in some embodiments of the present disclosure, an additional material may be added during the manufacturing process 73 or 76 . For example, a tobacco material such as tobacco powder and a clove material such as clove powder may be further added during the manufacturing process 73 or 76 . Flavor granules 77 containing tobacco powder may be used to simultaneously enhance eugenol migration and nicotine migration, and flavor granules 77 including clove powder are used to further improve clove flavor and flavor can be

Also, in some embodiments, cyclodextrin may be added during the granule manufacturing process to improve the flavor preserving ability of the flavor granules 77 . The cyclodextrin may act as a carrier for collecting flavor ingredients, thereby enhancing the flavor preserving ability of the flavor granules 77 . The cyclodextrin may comprise at least one of alpha, gamma or beta cyclodextrin.

In addition, the cyclodextrin is mixed with a specific solvent (e.g. ethanol) and added as a solution, in which case the concentration of the cyclodextrin in the solution may be, for example, about 1% to about 70%. Preferably, the concentration can be from about 3% to about 60%, more preferably from about 5% to about 50%, from about 6% to about 45%, from about 7% to about 40%, from about 8% to about 37%, from about 9% to about 33% or from about 10% to about 30%. This is because, when too little cyclodextrin is added, the fragrance component is not well captured, and when too much is added, the cyclodextrin does not dissolve well in the solvent and floats, which may negatively affect granule formation.

On the other hand, it should be noted that the manufacturing process shown in FIG. 7 corresponds to an embodiment of the method for manufacturing flavor granules. In another embodiment of the present disclosure, flavor granules (e.g. 77) may be prepared based on a rotary spray, top spray, or bottom spray method, or a combination thereof. However, in order to rapidly produce high-quality flavor granules (e.g. 77), it may be preferable to prepare flavor granules (e.g. 77) according to the manufacturing process shown in FIG. 7 .

In addition, the hardness of the flavor granules (e.g. 77) prepared by the above-described method for producing flavor granules may be 80% or more, preferably 85% or 90% or more, more preferably 91%, 93%, 95% or 97% or more. Here, the hardness of the flavor granules may be a value measured according to the national standard test method, KSM-1802 ("Activated carbon test method"). For details of the method for measuring the hardness of flavor granules and the meaning of the measured values, refer to the national standard KSM-1802.

In addition, the hardness of the flavor granules (e.g. 77) prepared by the above-described method for producing flavor granules may be 80% or more, preferably 85% or 90% or more, more preferably 91%, 93%, 95% or It can be more than 97%. Here, the hardness of the flavor granules may be a value measured in accordance with the national standard KSM-1802 ("Activated carbon test method"). For the method of measuring the hardness of flavor granules and the meaning of the measured values, refer to the national standard KSM-1802.

So far, a method for preparing flavor granules according to some embodiments of the present disclosure has been described with reference to FIG. 7 . According to the above-described method, granules are rapidly formed through the top spray process, and the quality of the granules can be improved through the rotary spray process. Accordingly, the production time of the granules may be shortened, and the quality of the manufactured granules may be improved.
