Description

[Technical Field]

[0001] The present invention relates to a capsule for an aerosol product including a cooling block, and to an aerosol product including the same. [Background technology]

[0002] Although some cooling agents have been used independently in shaving foam, toothpaste, mouthwash, and food products, there have been no cases where they have been used in aerosol products as a menthol substitute by utilizing a cooling block that incorporates the cooling agent's flavoring design technology.

[0003] Meanwhile, in current aerosol products, menthol accounts for a higher proportion than other flavoring substances, and only by adding the key characteristics of menthol and providing differentiation and diversity from existing menthols can a product be competitive with existing menthol products. Therefore, it is considered a pressing issue to develop menthol substitutes and secure product application technology so that the competitiveness of existing products can be maintained by realizing menthol-like characteristics and providing continuous benefits to consumers.

[0004] Meanwhile, the sensory characteristics of menthol can be divided into primary and secondary characteristics, with primary characteristics including cooling (refreshing feeling, body), freshness (clean feeling without dryness), and minty (minty aroma), while secondary characteristics include herbal, green, and earthy.

[0005] In order to realize such complex menthol sensory characteristics, it can be seen that the use of a specific cooling agent alone is extremely limited, and menthol-like characteristics can be realized only through blending technology that reflects the characteristics of various cooling agents, so it can be seen that recipe development for this is essential. Summary of the Invention [Problem to be solved by the invention]

[0006] In this situation, in order to overcome the above-mentioned problems and / or limitations of the existing technology, the present invention aims to provide a capsule for an aerosol product and an aerosol product containing the same, using a cooling block having a specific combination of cooling agents.

[0007] However, the problems to be solved by the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by a person having ordinary skill in the relevant technical field from the following description. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, since various modifications can be made to the embodiments, the scope of the patent application is not limited or restricted by these embodiments. It should be understood that all modifications, equivalents, or alternatives to the embodiments are included in the scope of the patent.

[0015] The terms used in the examples are used merely for the purpose of explanation and should not be construed as limiting. The singular term includes the plural term unless the context clearly dictates otherwise. In this specification, the terms "comprise" or "have" and the like are intended to specify the presence of the features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should not be understood to preclude the presence or possibility of addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0016] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the embodiments belong. Terms defined in commonly used dictionaries, etc., should be interpreted as having a meaning consistent with the meaning they have in the context of the relevant art, and should not be interpreted as having an ideal or overly formal meaning unless expressly defined in this application.

[0017] In addition, in the description with reference to the accompanying drawings, the same components are denoted by the same reference numerals regardless of the drawing numerals, and redundant description thereof will be omitted. In describing the embodiments, if it is determined that a detailed description of related publicly known technology may unnecessarily obscure the gist of the embodiments, the detailed description thereof will be omitted.

[0018] Furthermore, when describing components of the embodiments, terms such as first, second, A, B, (a), (b), etc. are used to distinguish the components from other components, and the terms do not limit the essence, order, or sequence of the components.

[0019] Components having common functions to components included in any of the embodiments will be described using the same names in other embodiments. Unless otherwise specified, the description of one embodiment can be applied to other embodiments, and detailed description will be omitted to the extent that it overlaps.

[0020] Throughout the specification, the term "aerosol-producing article" can refer to anything that can generate an aerosol, and is used as a concept that includes not only combustion-type aerosol-producing articles such as tobacco (cigarettes) and cigars, but also non-combustion-heated aerosol-producing articles. The aerosol-producing article can include an aerosol-forming substance or an aerosol-forming substrate. The aerosol-producing article can also include a solid substance (tobacco medium) based on tobacco raw materials such as tabular tobacco, shredded tobacco, and reconstituted tobacco. The aerosol-forming substance can include a volatile compound.

[0021] Also, throughout the specification, "upstream" or "upstream direction" means a direction away from the mouth of a user smoking the aerosol product, and "downstream" or "downstream direction" means a direction toward the mouth of a user smoking the aerosol product. For example, in the combustion aerosol product 100 shown in Figure 1, the tobacco medium portion 120 is located upstream or in the upstream direction of the filter portion 110.

[0022] Furthermore, although the present specification uses examples of aerosol product 100 selected from the case of a combustion cigarette or a non-combustion (heated) cigarette used in conjunction with an aerosol generating device (not shown), such as an electronic cigarette device, the present specification is not limited to these examples and can include all of the above concepts.

[0023] In addition, in this specification, the term "cooling block" may refer to a flavor or cooling agent composition consisting of a combination of specific cooling agents developed in the present application to impart the refreshing, clean, minty, and other properties of menthol.

[0024] According to one embodiment of the present invention, there is provided a capsule for an aerosol product comprising a cooling block, the capsule comprising: The cooling block is one or more cooling agents A selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; one or more cooling agents B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; one or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol; The present invention provides a capsule for an aerosol product, comprising:

[0025] The cooling agent A contained in the cooling block is a base-type cooling agent with relatively low volatility that is responsible for imparting body and longevity to the fragrance. Specific examples of the cooling agent A include WS-3 (N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide), WS-23 (N,2,3-trimethyl-2-isopropyl butanamide), and menthyl lactate, and combinations of these may also be included as needed.

[0026] WS-3 has good cooling sensation durability, and WS-5 has a similar cooling effect to WS-3, but may produce an unpleasant odor such as salty taste. Menthyl lactate can also provide a certain partial cooling sensation and maintain its durability, and WS-23 can also provide a cooling sensation, but the degree of cooling sensation may be less than that of menthyl lactate, and menthyl lactate can provide a cleaner or milder sensation than WS-23.

[0027] Furthermore, when used in combination with WS-3, the menthyl lactate can neutralize the harsh taste of WS-3. From a comprehensive perspective, it is preferable to use a mixture of WS-3 and menthyl lactate in order to provide a cooling sensation, lasting power, a refreshing sensation, a mild sensation, etc.

[0028] Meanwhile, the content of the low-volatility base-type cooling agent A contained in the capsule cooling block according to one embodiment of the present invention may be 10% to 60% by weight, preferably 15% to 55% by weight, and more preferably 20% to 50% by weight.

[0029] If the content of Cooling Agent A exceeds the upper limit, the overall harmonious flavor of the fragrance (cooling sensation, minty character, fresh, herbal harmony) may be lost, the fragrance may become heavy, and the expression of the middle-type Cooling Agent B and top-type Cooling Agent C may be suppressed, resulting in negative consequences. If the content of Cooling Agent A is less than the lower limit, the content of Cooling Agent A may be so small that the cooling sensation imparting effect is weak and the harmonious flavor may be reduced.

[0030] The content of WS-3 contained in the cooling agent A may be 5% to 20% by weight, preferably 10% to 15% by weight, based on the total weight of the cooling block, and the content of menthyl lactate may be 5% to 40% by weight, more preferably 30% to 40% by weight.

[0031] When the contents of WS-3 and menthyl lactate fall within the above-mentioned preferred ranges, the overall effects such as cooling sensation, lasting power, refreshing sensation, and mild sensation are the best, as mentioned above, and the difference in effects depending on the ranges will be clearly seen in the examples and comparative examples described in detail later.

[0032] The cooling agent B contained in the cooling block is a medium-type cooling agent with medium volatility that plays a role in enhancing the fragrance character. Specific examples of the cooling agent B include isopulegol, 4-terpineol, menthone, and menthyl acetate, and combinations thereof may also be included as needed.

[0033] Among the types of cooling agents B, menthone can impart a minty feeling, and menthyl acetate plays a role in harmoniously connecting the base, middle, and top notes so that the individual characteristics of the base-type cooling agent A described above and the top-type cooling agent C described below do not stand out too much. Furthermore, isopulegol exhibits an earthy feeling, and 4-terpineol can bring out a harsh feeling. However, since isopulegol is an expensive ingredient and the harsh feeling of 4-terpineol can cause negative impressions to smokers, considering the objective of the present invention to achieve properties most similar to menthol, the combination of menthone and menthyl acetate is considered to be preferable.

[0034] Meanwhile, the content of the middle-type cooling agent B having medium volatility contained in the cooling block of the capsule according to one embodiment of the present invention may be 5 wt% to 50 wt%, preferably 10 wt% to 45 wt%, and more preferably 15 wt% to 40 wt%.

[0035] If the content of cooling agent B exceeds the upper limit, it may inhibit the combination with base-type cooling agent A and top-type cooling agent C, thereby reducing the overall harmonious flavor of the fragrance and limiting the expression of the unique fragrance characteristics of top-type cooling agent C. If the content of cooling agent B is below the lower limit, the content of cooling agent B is so small that the minty character-imparting effect is weak, and the harmonious flavor may be reduced.

[0036] Furthermore, the content of menthone contained in the cooling agent B may be 10% by weight to 30% by weight, and preferably 15% by weight to 25% by weight, based on the total weight of the cooling block. Also, the content of menthyl acetate may be 5% by weight to 20% by weight, and more preferably 2% by weight to 8% by weight.

[0037] When the contents of menthone and menthyl acetate are within the above-mentioned preferred ranges, as can be seen from the comparison between Examples 1 and 2 and Comparative Example 2 described below, it is found that the fragrance intensity and harmonious taste are good, and further, a minty feeling like menthol is imparted, and the characteristics of the top, middle and base type cooling agents are combined to effectively achieve harmony.

[0038] The cooling agent C contained in the cooling block is a highly volatile top-type cooling agent that is responsible for the strength, unique characteristics, and diffusibility of the fragrance. Specific examples of the cooling agent C include cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol, and combinations thereof may also be included as needed.

[0039] Among the cooling agents C, cis-3-hexenol can impart a grassy, ​​green note, while hexyl alcohol can impart an oily feel in addition to the grassy smell. Eucalyptol enhances the minty characteristics and cooling effect and can impart natural, herbal, and fresh notes. 1,4-cineol exhibits herbal, green, fresh, and light fragrance characteristics, but has the disadvantage of being less harmonious than eucalyptol. Therefore, it is preferable to use eucalyptol as the cooling agent C.

[0040] Meanwhile, the content of the highly volatile top-type cooling agent C contained in the cooling block of the capsule according to one embodiment of the present invention may be more than 0 wt% and not more than 40 wt%, preferably 0.5 wt% to 10 wt%, or 0.5 wt% to 5 wt%.

[0041] If the content of Cooling Agent C exceeds the upper limit, the fragrance's inherent characteristics will be artificial rather than natural, resulting in a heavy fragrance and a lack of harmony with the middle-type Cooling Agent B. On the other hand, if Cooling Agent C is not included, the fragrance's inherent characteristics will not be conveyed, resulting in a less complete fragrance and a loss of the overall freshness and lightness.

[0042] These results can also be confirmed through a comparison of sensory evaluation between Examples 1 and 2 described below and Comparative Example 3, which does not contain eucalyptol. This shows that Cooling Agent C has a significant effect on the refreshing feeling of menthol, the enhancement of fragrance strength, and the clean aftertaste, despite being contained in a small amount in the cooling block.

[0043] Meanwhile, the cooling block included in the capsule for the aerosol product according to one embodiment of the present invention may further include a solvent for mixing the agents in addition to the above-mentioned cooling agent A, cooling agent B, and cooling agent C. In this case, the solvent used may include one or more selected from the group consisting of alcohol, propylene glycol, and glycerol, and may be preferably alcohol.

[0044] In this case, the content of the solvent contained in the cooling block may be about 50% by weight or less, preferably about 15% to 30% by weight, based on the total weight of the cooling block.

[0045] In this way, by adjusting the amount of solvent contained in the cooling block, the harmonious taste of cooling agents A, B, and C can be maintained and their role as menthol substitutes can be maintained, but only the flavor intensity can be adjusted.

[0046] Meanwhile, the cooling block can be manufactured, for example, according to a method including the following steps.

[0047] a) preparing cooling agent A, cooling agent B, and cooling agent C raw materials; and b) Mixing the cooling agent A, the cooling agent B and the cooling agent C into a solvent.

[0048] In this case, the cooling agent A is one or more selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate; the cooling agent B is one or more selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; The cooling agent C can be one or more selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol.

[0049] The solvent that can be used in step b) is substantially the same as the solvent mentioned above, and is preferably alcohol.

[0050] A capsule including a cooling block according to one embodiment of the present invention can be used for an aerosol product, and the aerosol product may be a smoking article including a tobacco medium portion, a filter portion, a wrapper, etc.

[0051] In this case, the capsule including the cooling block can be used by being included in the filter unit.

[0052] On the other hand, the amount of cooling block contained in the capsule can be added in an amount of 50g to 250g, preferably 100g to 105g, per 100kg of tobacco medium (cut grass). If the amount of cooling block is more or less than the above range, the effect of the cooling block intended by the present invention may be reduced.

[0053] In addition, the filter portion included in the aerosol product may be divided into two or more segments, such as a first filter portion and a second filter portion, and regardless of the location, if one or more of the two or more segments includes a capsule containing a cooling block according to an embodiment of the present invention, it is within the scope of the present invention. Furthermore, the shape of such a capsule may be spherical or cylindrical, and preferably has a core-shell structure, but is not limited thereto.

[0054] For example, when the capsule for the aerosol product has a core-shell structure, the core may specifically include the cooling block, and the shell may be made of a membrane material containing water, a plasticizer, agar, pectin, and sodium alginate.

[0055] Furthermore, the tobacco medium portion typically contains a tobacco substance containing nicotine, such as leaf tobacco, and may further contain excipients such as binders and other additives. For example, the tobacco medium contained in the tobacco medium portion of the present invention may be prepared in the form of granules containing a tobacco substance and excipients.

[0056] In the present invention, the tobacco material is a material constituting the aerosol-forming substrate, and may be tobacco leaf strips, tobacco stems, tobacco dust generated during tobacco processing, and / or tobacco leaf strips. The tobacco leaf may be at least one selected from the group consisting of flue-cured, burley, oriental, cigar, and toasted tobacco, but is not limited thereto.

[0057] Meanwhile, as shown in Figure 1 (combustion aerosol product), a wrapper according to one embodiment of the present invention may include a wrapper for each component of the aerosol product, such as a tobacco medium wrapper 120a that wraps the tobacco medium section, a filter section wrapper (filter paper) 110a that wraps the filter, etc. In addition, as described above, if the filter section is divided into multiple segments, a wrapper for wrapping each segment may be included. Also, to secure the connection between the tobacco medium section and the filter section, a tipping wrapper 130 that wraps a portion of the tobacco medium section and the filter section may be included, and an outer wrapper 140 that is located at the outermost periphery of the aerosol product and wraps the tobacco medium section and filter section, etc., may be included to maintain the overall shape of the aerosol product.

[0058] The tipping wrapper, which connects the tobacco medium portion and the filter, may be selectively formed with one or more perforations along the circumferential direction to allow external air to flow in or internal gas to flow out, thereby achieving the air dilution rate of the cigarette and controlling the amount of mainstream smoke components transferred.

[0059] Meanwhile, a capsule including a cooling block according to an embodiment of the present invention can also be included in a non-combustion heated aerosol product, as shown in FIG.

[0060] In accordance with yet another aspect of the present invention, there is provided a method of manufacturing a capsule for an aerosol product comprising: Step S1 of producing a membrane material; Step S2 of producing capsules with a membrane material and a cooling block; Step S3 of hardening the capsule; a step S4 of drying the capsules; Including, The cooling block comprises one or more cooling agents A selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate; one or more cooling agents B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; one or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol; The present invention provides a method for producing a capsule for an aerosol product, comprising:

[0061] In this embodiment, step S1 of producing the membrane material is to produce a material for the membrane that encases the cooling block, and may consist of a process of weighing out the components that make up the membrane material and then dissolving the components to form the membrane material. The components that make up the membrane material are agar, pectin, sodium alginate, and glycerin as a plasticizer, and these components can be dissolved in water to form the membrane material. At this time, the viscosity of the produced membrane material can be, for example, 400 to 700 cp (centipoise), preferably 500 to 650 cps.

[0062] Considering the roles of the components that make up the membrane, first, agar plays a role in hardening due to temperature, allowing the initial capsule pattern to be formed, and pectin plays a role in adjusting the intermediate between agar and sodium alginate, affecting the hardening degree of agar and the calcium ion bond of sodium alginate to form the initial capsule pattern, and also plays a role in improving stability and moisture absorption, contributing to membrane formation.

[0063] The sodium alginate hardens with calcium ions, thereby adjusting the strength of the capsule, forming a membrane, and improving moisture absorption stability through ion hardening.

[0064] Glycerin acts as a plasticizer, helping to mold the capsules and providing elasticity to them. While the greater the amount of glycerin, the greater the capsule's elasticity. However, glycerin itself is highly hygroscopic, and its long-term stability may decrease. Conversely, if the amount of glycerin is too small, the capsules will be less elastic and more easily broken by external factors. Therefore, it is important to combine the appropriate amount of glycerin.

[0065] The membrane material can be composed of, for example, 45 to 55% by volume of agar, 35 to 45% by volume of pectin, and 5 to 15% by volume of sodium alginate, excluding water and glycerin.

[0066] On the other hand, the step S2 of producing the capsule is a step of producing the capsule by wrapping the cooling block with the film material. The specific shape of the capsule is as described above.

[0067] The capsules manufactured through step S2 may then undergo a hardening step S3. In this case, the capsules may be hardened using an ethanol preparation, which is carried out by immersing the capsules in a 70 to 100% ethanol preparation for about 3 to 5 minutes.

[0068] After the hardening step S3, step S4 can be performed to dry the capsules according to a specific temperature, humidity, air volume, or rotation speed. After drying, the capsules are separated into batches and stored on a drying plate for a conditioning process, thereby finally producing capsules for aerosol products.

[0069] The present invention will be described in more detail with reference to the following examples and comparative examples. However, the present invention is not limited to these examples, and the scope of the present invention is not limited to these examples.

[0070] [Example] (1) Manufacturing Example 1: Manufacturing of Cooling Block [Example 1] To manufacture a cooling block according to one embodiment of the present invention, WS-3 and menthyl lactate in powder form, and menthone, menthyl acetate, and eucalyptol in liquid form were prepared as fragrance raw materials. The prepared WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol raw materials were mixed and stirred for a certain period of time in alcohol, which was the solvent, to ensure they were sufficiently dissolved.

[0071] The amounts of the added raw materials and alcohol were adjusted as shown in Table 1 below.

[0072] [Example 2] A cooling block was manufactured in the same manner as in Example 1, except that the cooling agent contents were adjusted so that the WS-3 content was 25 wt % and the menthone content was 10 wt % and dissolved in alcohol.

[0073] [Comparative Example 1] A cooling block was prepared in the same manner as in Example 1, except that WS-23 was dissolved in alcohol instead of WS-3, and the amount of WS-23 added was 15 wt % based on the total weight of the prepared cooling block.

[0074] Comparative Example 2 A cooling block was prepared in the same manner as in Example 1, except that 4-terpineol was dissolved in alcohol instead of menthone, and the content of the 4-terpineol added was 20 wt % based on the total weight of the prepared cooling block.

[0075] Comparative Example 3 A cooling block was prepared in the same manner as in Example 1, except that 1,4-cineole was dissolved in alcohol instead of eucalyptol, and the content of the 1,4-cineole added was 2 wt % based on the total weight of the prepared cooling block.

[0076] The types and contents of the cooling agents contained in the cooling blocks manufactured in Examples 1 and 2 and Comparative Examples 1 to 3 are summarized in Table 1 below.

[0077] [Table 1]

[0078] (2) Production Example 2: Production of capsules containing cooling blocks A membrane material was prepared by dissolving 50% by volume of agar, 40% by volume of pectin, and 10% by volume of sodium alginate in glycerin and water. The cooling block prepared in Example 1 was then placed inside the membrane material, and spherical capsules were produced using a capsule manufacturing device. The spherical capsules were then immersed for 5 minutes in an ethanol preparation prepared by mixing distilled water and ethanol in a volume ratio of 7:3 to undergo a hardening process, and then dried, finally producing capsules containing the cooling block.

[0079] (3) Test Example 1: Sensory evaluation of the manufactured cooling blocks Sixteen panel members from KT&G R&D in-house inhaled aerosol products containing cooling block-containing capsules in the filter portion of Examples 1-2 and Comparative Examples 1-3, and then evaluated the smoking taste strength, refreshing menthol feeling, smooth throat feel, flavor strength, harmonious taste, clean aftertaste, and satisfaction level on a scale of 1 to 9. The average values ​​of the evaluation results were calculated and are shown in Table 2 below.

[0080] [Table 2]

[0081] Referring to the results in Table 2 above, it can be seen that the evaluation results of Examples 1 and 2, which contain all of WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol, show better results in terms of smoking taste intensity, refreshing menthol feeling, fragrance intensity, harmonious taste, clean aftertaste, and overall satisfaction, compared to Comparative Examples 1 to 3, which lack WS-3, menthone, or eucalyptol, respectively.

[0082] More specifically, Comparative Example 1 lacking WS-3 was found to be inferior in terms of smoking intensity and clean aftertaste, among other items, while Comparative Example 2 lacking menthone was found to be inferior in terms of flavor intensity and harmonious flavor.Furthermore, Comparative Example 3 lacking eucalyptol was found to be rated lower than the Examples in terms of menthol refreshing flavor, flavor intensity, harmonious flavor, and clean aftertaste.

[0083] That is, this makes it possible to understand that the overall satisfaction level of Examples 1 and 2 is superior to that of Comparative Examples 1 to 3 among smokers.

[0084] On the other hand, when Examples 1 and 2 in which the contents of WS-3 and menthone were adjusted differently were compared, Example 2 in which an excessive amount of WS-3 was added or a small amount of menthone was added showed slight differences compared to Example 1 in terms of menthol refreshing feeling, smoothness in the throat, strength of fragrance, harmonious taste and clean aftertaste, and also showed slightly inferior results in terms of overall satisfaction.

[0085] (4) Test Example 2: Sensory Evaluation Comparison with Current Cigarettes [Comparison of the aerosol product containing the capsules of Manufacturing Example 2 with the current ESSE CHANGE 1 mg] The cooling block-containing capsules prepared in Preparation Example 2 above were applied to the aerosol product.

[0086] Next, 13 members of KT&G R&D's in-house panel smoked the current ESSE CHANGE 1mg (a prototype product in which menthol was mixed with the secondary flavoring agent when making ESSE CHANGE 1mg) and the aerosol product containing the cooling block-containing capsules of Preparation Example 2, and then evaluated the smoking strength, refreshing menthol sensation, smoothness aftertaste, fragrance strength, harmonious taste, clean aftertaste, and satisfaction level on a scale of 1 to 9. The average values ​​for the evaluation results were calculated and are shown in Table 3 below.

[0087] [Table 3]

[0088] [Comparison of the aerosol product containing the capsules of Manufacturing Example 2 with the general ESSE CHANGE 1 mg] Sixteen members of KT&G R&D's in-house panel smoked ESSE CHANGE 1mg (a prototype product in which menthol and cooling block were not mixed in the secondary flavoring) and the aerosol product containing capsules containing cooling block from Preparation Example 2, and then evaluated using the same method as above. The average values ​​for the evaluation results were calculated and are shown in Table 4 below.

[0089] [Table 4]

[0090] [Comparison of the aerosol product containing the capsules of Manufacturing Example 2 with the current RAISON FRENCH BLACK] Sixteen members of the KT&G R&D in-house panel inhaled the current RAISON FRENCH BLACK and the aerosol product containing the cooling block-containing capsules of Preparation Example 2, and then the same evaluation was carried out as described above. The average values ​​of the evaluation results were calculated and are shown in Table 5 below.

[0091] [Table 5]

[0092] From the results of Test Example 2, it can be seen that the aerosol product containing the cooling block-containing capsule according to one embodiment of the present invention tends to have a higher menthol refreshing feeling, clean aftertaste, and overall satisfaction level than aerosol products such as ESSE CHANGE 1mg current, ESSE CHANGE 1mg regular, and RAISON FRENCH BLACK. This indicates that the cooling block can complement the taste acceptance and satisfaction of existing menthol products or can effectively achieve the main sensory characteristics.

[0093] As described above, although the embodiments have been described with limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, the described techniques may be performed in an order different from that described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a form different from that described, or may be substituted or replaced by other components or equivalents, and still achieve suitable results.
