Description

[Technical field]

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

[0002] Although there are cases where some cooling agents have been used alone in shaving foam, toothpaste, mouthwash, and food, 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 flavor design technology.

[0003] Meanwhile, in current aerosol products, menthol accounts for a high proportion compared to other flavoring substances, and only by imparting the main characteristics of menthol and differentiation and diversity from existing menthols can a product be made competitive compared to existing menthol products. Therefore, it is considered a pending 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 the primary characteristics being cooling (refreshing feeling, body), fresh (not dry and refreshing feeling), and minty (peppermint aroma), while the secondary characteristics include herbal, green, earthy, etc.

[0005] In order to realize such complex menthol sensory characteristics, it is considered that the use of a certain 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 is considered 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 problems and / or limitations of the existing technologies described above, 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the 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 merely used for the purpose of explanation and should not be construed as limiting. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this specification, the terms "include" or "have" 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 additional possibility 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 idealized or overly formal 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 duplicated 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, in 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 included in any of the embodiments and components having common functions will be described using the same names in other embodiments. Unless otherwise specified, the description of any of the embodiments may be applied to the other embodiments, and detailed description will be omitted to the extent that they overlap.

[0020] Throughout the specification, the term "aerosol-producing article" may mean anything capable of generating an aerosol, and is used as a concept including 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 may include an aerosol-generating substance or an aerosol-forming substrate. The aerosol-producing article may also include a solid substance (tobacco medium) based on tobacco raw materials, such as tabular tobacco, shredded tobacco, and reconstituted tobacco. The aerosol-generating substance may 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 FIG. 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 as an example a selection of the cases of the aerosol product 100 being 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 cases and may include all of the above concepts.

[0023] In addition, in this specification, the 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 plays a role in imparting body and persistence to the fragrance. Specific types 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 necessary.

[0026] WS-3 has good durability of cooling sensation, and WS-5 has a similar cooling effect to WS-3, but may produce an unpleasant odor such as salty taste. Menthyl lactate can provide a certain partial cooling sensation and an effect of maintaining the cooling sensation, and WS-23 can also provide a cooling sensation, but the degree of the cooling sensation may be inferior to that of menthyl lactate, and menthyl lactate can provide a refreshing or mild sensation compared to 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, refreshing sensation, mild sensation, etc.

[0028] Meanwhile, the content of the low-volatility base-type cooling agent A contained in the cooling block of the capsule according to one embodiment of the present invention may be 10% by weight to 60% by weight, preferably 15% by weight to 55% by weight, and more preferably 20% by weight 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 broken, the fragrance may become heavy, and the expression of the middle type cooling agent B and the top type cooling agent C may be suppressed, resulting in negative results. If the content of cooling agent A is less than the lower limit, the content of cooling agent A is so small that the cooling sensation imparting effect is low and the harmonious flavor may be reduced.

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

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

[0032] The cooling agent B contained in the cooling block is a middle-type cooling agent having a medium volatility and serving to enhance the character of the fragrance. Specific types of the cooling agent B include isopulegol, 4-terpineol, menthone, and menthyl acetate, and combinations thereof may also be included as necessary.

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

[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 inhibits the binding with base type cooling agent A and top type cooling agent C, 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 less than 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] The content of menthone contained in the cooling agent B may be 10% by weight to 30% by weight, preferably 15% by weight to 25% by weight, based on the total cooling block weight, and the content of menthyl acetate may be 5% by weight to 20% by weight, more preferably 2% by weight to 8% by weight.

[0037] When the content of menthone and menthyl acetate falls within the above-mentioned preferred range, as can be seen from the comparison of Examples 1-2 and Comparative Example 2 described later, it is found that the fragrance intensity and flavor harmony 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 show the harmony.

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

[0039] Among the types of cooling agent C, cis-3-hexenol can impart a grassy smell with a green note, such as a grassy smell, and hexyl alcohol can impart an oily feeling in addition to the grassy smell. Eucalyptol can enhance the minty characteristics and cooling effect and impart natural, herbal and fresh notes, and 1,4-cineol has 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 in this respect.

[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%, and 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 realization of the fragrance's unique 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 will not convey its unique characteristics, 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 that does not contain eucalyptol. This shows that Cooling Agent C has a significant effect on the refreshing feeling of menthol, enhancement of fragrance strength, and clean aftertaste, despite the small amount contained 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] At this time, the content of the solvent contained in the cooling block may be about 50% by weight or less, and preferably about 15% by weight 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 as is, 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 at least one 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 can 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 in a state where it is 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 part included in the aerosol product may be divided into two or more segments, such as a first filter part, a second filter part, etc., and regardless of the position of the two or more segments, 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 can be included in the scope of the present invention. Furthermore, the shape of such a capsule can be spherical or cylindrical, etc., and preferably has a core-shell structure, but is not limited thereto.

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

[0055] Furthermore, the tobacco medium part typically includes a tobacco material containing nicotine, such as tobacco leaves, and may further include excipients such as binders and other additives. For example, the tobacco medium included in the tobacco medium part of the present invention may be prepared in the form of granules including a tobacco material 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 leaf, and toasted tobacco, but is not limited thereto.

[0057] Meanwhile, the wrapper according to an embodiment of the present invention may include a wrapper for each component of the aerosol product as shown in Fig. 1 (combustion type aerosol product), and may be divided into a tobacco medium part wrapper 120a wrapping the tobacco medium part, a filter part wrapper (filter paper) 110a wrapping the filter, etc. In addition, as described above, when the filter part is divided into a plurality of segments, a wrapper for wrapping each of the segments may be included. In addition, in order to fix the connection between the tobacco medium part and the filter part, a tipping wrapper 130 wrapping a portion of the tobacco medium part and the filter part may be included, and an outer wrapper 140 may be included that is located at the outermost edge of the aerosol product while wrapping the tobacco medium part and the filter part, etc., in order to maintain the overall shape of the aerosol product.

[0058] The tipping wrapper that 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 realizing 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 may also be included in a non-combustion type heated aerosol product, as shown in FIG.

[0060] According to yet another aspect of the present invention, there is provided a method of manufacturing a capsule for an aerosol product comprising a cooling block, the method comprising the steps of: Step S1 of producing a membrane material; Step S2 of producing capsules with a membrane material and a cooling block; A 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] Step S1 of producing the membrane material in this embodiment is to produce the material of the membrane that wraps the cooling block, and can be composed of a process of weighing the amount of components that make up the membrane material, and then dissolving the components that make up the membrane material to form the membrane material. At this time, 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, and 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 of hardening by temperature, allowing the initial capsule pattern to be formed, and pectin plays a role of intermediate regulator between agar and sodium alginate, affecting the hardening degree of agar and calcium ion bond of sodium alginate to form the initial capsule pattern, and also plays a role of 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 the moisture absorption stability by ion hardening.

[0064] Glycerin acts as a plasticizer to help the capsules to be molded and to give them elasticity. However, the more glycerin there is, the higher the capsules' elasticity becomes. However, glycerin itself is highly hygroscopic, and its moisture absorption stability may decrease over the long term. Conversely, if the amount of glycerin is small, the capsules will have low elasticity and will easily break due to external factors. Therefore, it is important to combine the right 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 a capsule by wrapping a cooling block with the membrane 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, and the ethanol preparation 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, a step S4 of drying the capsules can be performed 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] Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to examples and comparative examples. However, these examples are provided to more specifically explain the present invention, and the scope of the present invention is not limited to these examples.

[0070] [Example] (1) Manufacturing Example 1: Manufacturing of Cooling Blocks [Example 1] In order to manufacture a cooling block according to an embodiment of the present invention, WS-3, 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 so that they were sufficiently dissolved in alcohol, which is a solvent.

[0071] At this time, 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 content of WS-23 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 added 4-terpineol 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 1,4-cineole was added to be 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 produced 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 a spherical capsule was prepared using a capsule manufacturing device. After that, the spherical capsule was immersed in an ethanol preparation prepared by mixing distilled water and ethanol in a volume ratio of 7:3 for 5 minutes to undergo a hardening process, and then dried, and finally a capsule containing a cooling block was prepared.

[0079] (3) Test Example 1: Sensory evaluation of the manufactured cooling blocks A panel of 16 members from KT&G R&D inhaled the aerosol products containing the cooling block-containing capsules of Examples 1-2 and Comparative Examples 1-3 in the filter section, and then evaluated the smoking taste strength, menthol refreshing feeling, smoothness on the throat, flavor strength, harmonious taste, refreshing 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, menthol refreshing feeling, fragrance intensity, harmonious taste, clean aftertaste and overall satisfaction, compared to Comparative Examples 1 to 3, which lack WS-3, menthone and eucalyptol, respectively.

[0082] More specifically, in the case of Comparative Example 1 lacking WS-3, it can be seen that the smoking taste intensity and the degree of clean aftertaste are inferior among various items, and in the case of Comparative Example 2 lacking menthone, it can be seen that it is inferior in terms of flavor intensity and harmonious taste. Also, in the case of Comparative Example 3 lacking eucalyptol, it can be seen that it is rated lower than the Examples in terms of menthol refreshing feeling, flavor intensity, harmonious taste, and clean aftertaste.

[0083] That is, this makes it possible to understand that Examples 1 and 2 are more satisfactory overall than Comparative Examples 1 to 3 from the perspective of smokers.

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

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

[0086] Then, 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 into the secondary flavoring 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 feeling of menthol, smoothness on the throat, fragrance strength, harmonious taste, refreshing feeling of aftertaste, and satisfaction on a scale of 1 to 9. The average values ​​of the evaluation results were calculated and are shown in Table 3 below.

[0087] [Table 3]

[0088] [Comparison between the aerosol product containing the capsules of Production Example 2 and the general ESSE CHANGE 1mg] A panel of 16 members from KT&G R&D in-house 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 of Preparation Example 2, and then evaluated in the same manner as above. The average values ​​of the evaluation results were calculated and are shown in Table 4 below.

[0089] [Table 4]

[0090] [Comparison between the aerosol product containing the capsules of Manufacturing Example 2 and the current RAISON FRENCH BLACK] A panel of 16 members from KT&G R&D in-house conducted the same evaluation as above after inhaling the current RAISON FRENCH BLACK and the aerosol product containing the cooling block-containing capsules of Preparation Example 2. 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 including the capsule containing the cooling block 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 general and RAISON FRENCH BLACK, and it can be seen that the cooling block can complement the taste acceptance and satisfaction level of existing menthol products or can well realize the main sensory characteristics.

[0093] As described above, although the embodiments have been described with reference to limited drawings, those having ordinary skill in the art may apply various technical modifications and variations based on the above.
