Description

Technical Field

[0001] The present invention relates to cooling blocks containing cooling agents, and aerosol-generating articles containing the same. Prior Art

[0002] At present, some cooling agents have been used alone in shaving foams, toothpastes, mouthwashes and foods, but cooling blocks containing flavored cooling agents have not yet been used to replace menthol in aerosol-generating products.

[0003] Compared to other flavoring substances, the majority of current aerosol-generating products use menthol. Only products that possess menthol's key properties or exhibit differentiation and diversity compared to existing menthols are competitive. To achieve menthol-like properties, maintain product competitiveness, and continue to provide consumer convenience, the development of menthol substitutes and product application technologies are urgent challenges.

[0004] On the one hand, the sensory characteristics of menthol can be divided into main characteristics and auxiliary characteristics. The main characteristics include Cooling (cooling feeling, body), Fresh (not dry and fresh), Minty (minty fragrance); the auxiliary characteristics include Herbal (herbal), Green (green grass fragrance), Earthy (earth fragrance), etc.

[0005] It is difficult to achieve the above-mentioned complex sensory properties of menthol by using certain specific cooling agents alone. The menthol-like properties can only be reproduced by mixing the characteristics of different cooling agents, so relevant formulas must be developed. Summary of the Invention

[0006] [Problems to be solved by the invention]

[0007] In this case, in order to overcome the status quo and / or limitations of the above-mentioned prior art, the present invention aims to provide a cooling block comprising a specific cooling agent combination and an aerosol-generating product comprising the cooling block.

[0008] However, the problems to be solved by the present invention are not limited to the above contents, and those skilled in the art will clearly understand other unmentioned problems through the following description.

[0009] [Technical means to solve the problem]

[0010] According to one embodiment of the present invention, a cooling block for an aerosol-generating product is provided, comprising:

[0019] The cooling agent C is at least one selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.

[0020] According to another aspect of the present invention, an aerosol generating product comprising a tobacco medium portion, a filter rod portion, and a packaging material is provided, comprising a cooling block according to an embodiment of the present invention.

[0021] According to another aspect of the present invention, there is provided a method for preparing an aerosol-generating article comprising a tobacco medium portion, a filter rod portion, and a packaging material, comprising the following steps:

[0022] In the tobacco medium section, add 50g to 250g of cool flavor blocks per 100kg of tobacco medium.

[0023] The cooling block includes the cooling block according to an embodiment of the present invention.

[0024] [Effects of the Invention]

[0025] According to an embodiment of the present invention, a cooling block containing a specific combination of cooling agents can achieve the main sensory characteristics of menthol products, such as cooling, freshness, and mintiness, improve the acceptance and satisfaction of the taste, and can also replace products that use menthol to supplement menthol and better achieve the menthol feeling.

[0026] It should be understood that the effects of the present invention are not limited to the above-mentioned effects, but also include all effects that can be derived from the specific description of the present invention or the invention recorded in the scope of the invention application. Simple diagram description

[0027] FIG1 is a schematic structural diagram of a combustion-type aerosol-generating product including a cooling block according to an embodiment of the present invention. FIG2 is a schematic structural diagram of a non-combustion (heating) aerosol-generating product comprising a cooling block according to an embodiment of the present invention. Implementation Method

[0028] The following embodiments are described in detail with reference to the accompanying drawings. It should be understood that various modifications may be made to the embodiments, and the scope of the present application is not limited to the following embodiments. All modifications to the embodiments, their equivalents, and even their replacements are intended to fall within the scope of the present invention.

[0029] The terms used in the examples are intended only to illustrate specific embodiments and are not intended to limit their scope. Unless otherwise specified, singular expressions include the plural. In this specification, terms such as "including" or "having" are used to express the presence of a feature, number, step, operation, component, accessory, or combination thereof described in the specification, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, accessories, or combinations thereof.

[0030] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the ordinary meanings understood by persons of ordinary skill in the art. Commonly used terms, as defined in dictionaries, should be understood as having the meanings inherent in the relevant technical context and, unless explicitly defined in this specification, should not be interpreted as idealizing or overly formalizing.

[0031] Furthermore, in the description of the accompanying drawings, identical components will be denoted by the same reference numerals regardless of the figure numbers, and duplicate descriptions will be omitted. In the description of the embodiments, if a detailed description of a related known technology is judged to unnecessarily obscure the embodiments, the detailed description will be omitted.

[0032] Furthermore, when describing the components of the embodiments, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish one component from other components and are not intended to limit the nature or order of the corresponding components.

[0033] When a component has the same function as a component of a certain embodiment, the same name will be used to describe it in the other embodiment. Unless a counterexample is mentioned, the description of one embodiment can be applied to other embodiments, and detailed descriptions of the repeated content may be omitted.

[0034] Throughout this specification, "aerosol-generating product" refers to any article capable of generating aerosols. This includes combustion-type aerosol-generating products such as cigarettes and cigars, as well as non-combustion-type aerosol-generating products. Aerosol-generating products may contain an aerosol-generating substance or an aerosol-forming matrix. Furthermore, aerosol-generating products may contain a solid substance (cigarette medium) based on tobacco raw materials, such as tobacco flakes, shredded tobacco, or reconstituted tobacco. Aerosol-generating products may also contain volatile compounds.

[0035] Throughout this specification, "upstream" or "upstream direction" refers to a direction away from the mouth of a user who inhales an aerosol-generating article, and "downstream" or "downstream direction" refers to a direction toward the mouth of a user who inhales an aerosol-generating article. For example, in the combustion-type aerosol-generating article 100 shown in FIG. 1 , the tobacco medium portion 120 is located upstream or in the upstream direction of the filter portion 110.

[0036] Furthermore, in this specification, the aerosol-generating product 100 is exemplified by selecting one of non-combustion (heating) cigarettes such as combustion-type cigarettes or electronic cigarettes used with an aerosol-generating device (not shown), but the present invention is not limited thereto and may include all of the above concepts.

[0037] In addition, in this specification, a cooling block may refer to a flavor or coolant composition composed of a specific cooling agent combination developed herein, which is used to provide a cooling sensation, a refreshing sensation, a minty flavor, etc. similar to menthol characteristics.

[0038] According to one embodiment of the present invention, a cooling block for an aerosol-generating product is provided, comprising:

[0039] At least one cooling agent A selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate;

[0040] At least one cooling agent B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; and

[0041] At least one cooling agent C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.

[0042] The cooling agent A contained in the cooling block is a relatively low-volatility, base-type cooling agent that imparts body and long-lasting flavor. Specific types of 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. Combinations of these may also be included as needed.

[0043] WS-3 provides a long-lasting cooling sensation, while WS-5 offers a similar cooling sensation, but may also impart a salty or other unpleasant odor. Menthyl lactate also provides a certain degree of cooling that lasts longer. WS-23 also provides a cooling sensation, but the degree may be less than that of menthyl lactate. Compared to WS-23, menthyl lactate may offer a more refreshing or gentler sensation.

[0044] In addition, menthyl lactate can neutralize the spicy taste of WS-3 when used together with WS-3. Taking all factors into consideration, in order to provide a cooling feeling, long-lasting feeling, fresh feeling and mild feeling, it is preferred to use WS-3 and menthyl lactate in combination.

[0045] Meanwhile, the content of the low-volatility after-adjusting cooling agent A in the cooling block according to one embodiment of the present invention may be 10 wt % to 60 wt %, preferably 15 wt % to 55 wt %, and more preferably 20 wt % to 50 wt %.

[0046] When the content of cooling agent A exceeds the upper limit, the balance of the overall fragrance (the balance of cooling, minty, fresh, and herbal, etc.) will be disrupted, causing the fragrance to be too strong and suppressing the fragrance of cooling agent B as the middle note and cooling agent C as the top note, bringing negative effects; and when the content is less than the lower limit, due to the lack of cooling agent A, the cooling feeling will be reduced, disrupting the overall balance.

[0047] In addition, the content of WS-3 in the cooling agent A can be 5% to 20% by weight, preferably 10% to 15% by weight, of the total weight of the cooling block. In addition, the content of menthyl lactate can be 5% to 40% by weight, more preferably 30% to 40% by weight.

[0048] When the contents of WS-3 and menthyl lactate are within the above-mentioned ideal ranges, as described above, the cooling sensation, persistence, freshness, and mildness are generally good. The differences in effects based on different ranges will be explained in detail in the following examples and comparative examples.

[0049] The cooling agent B contained in the cooling block is a middle-note cooling agent with moderate volatility that enhances the flavor characteristics. Specific types of cooling agent B include isopulegol, 4-terpineol, menthone, and menthyl acetate, and combinations thereof may also be included as needed.

[0050] Among the cooling agents B, menthone imparts a minty flavor, while menthyl acetate coordinates the base, middle, and top notes, preventing the individual characteristics of the cooling agent A and the top cooling agent C, described later, from being overly prominent. Furthermore, isopulegol contributes to an earthy aroma, while 4-terpineol enhances the harshness. However, isopulegol is expensive, and the irritation of 4-terpineol can negatively impact smokers. Therefore, considering the goal of the present invention is to achieve properties most similar to menthol, a combination of menthone and menthyl acetate is preferred.

[0051] Meanwhile, the cooling block according to one embodiment of the present invention may contain the moderately volatile cooling agent B in an amount of 5 to 50 wt %, preferably 10 to 45 wt %, and more preferably 15 to 40 wt %.

[0052] When the content of cooling agent B exceeds the above upper limit, it will affect the connection between cooling agent A as the base note and cooling agent C as the top note, affect the overall fragrance balance, and limit the unique fragrance of cooling agent C as the top note; when it is less than this range, the mint flavor will be reduced due to the insufficient content of cooling agent B, affecting the overall balance.

[0053] In addition, the menthone content of the cooling agent B is 10% to 30% by weight, preferably 15% to 25% by weight, based on the total weight of the cooling block. Furthermore, the menthyl acetate content can be 5% to 20% by weight, more preferably 2% to 8% by weight.

[0054] When the contents of menthone and menthyl acetate are within the above preferred ranges, the aroma intensity and overall balance are good, as can be confirmed by comparing Examples 1 to 2 with Comparative Example 2. Furthermore, the aroma has a minty flavor similar to menthol, and the cooling agent characteristics as top, middle, and base notes are integrated to form an overall balance.

[0055] The cooling agent C contained in the cooling block is a top-note cooling agent with a fast volatilization rate and has a strong, unique, and dispersible fragrance. Specific types of the cooling agent C include cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol, and combinations thereof may be included as needed.

[0056] Among the cooling agent C types, cis-3-hexenol provides a grassy, ​​herbaceous aroma, while hexanol further imparts an oily note. Furthermore, eucalyptol enhances the minty and cooling effects, imparting a natural, herbal, and fresh aroma. While 1,4-cineole has herbal, grassy, ​​refreshing, and light aroma characteristics, its drawback is that its overall harmony is inferior to eucalyptol. Therefore, considering these factors, eucalyptol is the preferred cooling agent C.

[0057] At the same time, the content of the top-adjusting cooling agent C with a fast volatilization rate contained in the cooling block according to one embodiment of the present invention can be greater than 0 wt % and less than 40 wt %, preferably 0.5 wt % to 10 wt %, or 0.5 wt % to 5 wt %.

[0058] If the content of cooling agent C exceeds the upper limit, the natural aroma characteristics may not be achieved, resulting in an artificial and overly strong aroma, and the balance with the middle-note cooling agent B may be disrupted. On the other hand, if cooling agent C is not included, the uniqueness of the fragrance may not be conveyed, and the overall freshness and pleasantness may be lacking due to the reduced aroma completion.

[0059] These results were also confirmed by the sensory evaluation of Examples 1 and 2 and Comparative Example 3, which does not contain eucalyptol, described below. This indicates that, despite the low content of cooling agent C in the cooling block, it significantly impacts the cooling sensation of menthol, enhances its aroma intensity, and provides a refreshing aftertaste.

[0060] Meanwhile, the cooling block for an aerosol-generating product according to one embodiment of the present invention may contain, in addition to the cooling agents A, B, and C described in detail above, a solvent for mixing the aforementioned agents. In this case, the solvent used may include at least one selected from the group consisting of alcohol, propylene glycol, and glycerol, with alcohol being preferred.

[0061] At this time, the content of the solvent contained in the cooling block may be less than 50 wt % of the total weight of the cooling block, preferably about 15 wt % to 30 wt %.

[0062] In this way, the balance of cooling agents A, B, and C can be maintained by adjusting the amount of solvent contained in the cooling block, thereby maintaining the effect as a menthol substitute and only adjusting the flavor intensity.

[0063] Meanwhile, according to another embodiment of the present invention, there is provided a method for preparing a cooling block for an aerosol-generating product, comprising the following steps:

[0064] Step S1, preparing raw materials for cooling agent A, cooling agent B, and cooling agent C; and

[0065] Step S2: mixing the cooling agent A, cooling agent B, and cooling agent C with a solvent.

[0066] The cooling agent A is at least one selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate.

[0067] The cooling agent B is at least one selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate.

[0068] The cooling agent C is at least one selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.

[0069] At this time, the solvent that can be used is basically the same as the type of the above-mentioned solvent, preferably alcohol.

[0070] The cooling block according to one embodiment of the present invention can be used in an aerosol-generating product, which can be a smoking product comprising a tobacco medium portion, a filter rod portion, and packaging materials.

[0071] In this case, the cooling block can be included in at least one of the tobacco medium portion, filter portion, and packaging material of the aerosol-generating product. It can be directly sprayed onto the tobacco medium portion, filter portion, or packaging material itself for flavoring (for example, TJNS; Transfer Jet Nozzle System), or it can be included in the filter portion, etc. in the form of a capsule containing the cooling block.

[0072] For example, when a cooling block is added to the tobacco medium of the tobacco medium portion, the amount of the cooling block added can be 50 g to 250 g, preferably 100 g to 105 g, relative to 100 kg of tobacco medium (cut tobacco). When the amount of the cooling block is greater than or less than the above range, the cooling block effect expected by the present invention may be reduced.

[0073] Furthermore, the filter stick portion included in the aerosol-generating article can be divided into at least two sections, such as a first filter stick section and a second filter stick section. In this case, regardless of the placement, if at least one of the at least two sections contains a cooling block according to an embodiment of the present invention, or a capsule containing the same, it is considered to be within the scope of the present invention. Furthermore, the capsule can be spherical or cylindrical, but is not limited thereto.

[0074] In addition, the tobacco medium portion generally contains tobacco materials containing nicotine, such as tobacco leaves, and may further contain excipients such as adhesives or other additives. For example, the tobacco medium contained in the tobacco medium portion of the present invention can be prepared into a granular form containing tobacco substances and excipients.

[0075] In the present invention, tobacco material is the substance that forms the aerosol-forming substrate, and can be tobacco leaves, tobacco stems, dust generated during tobacco processing, and / or tobacco strips. The tobacco leaf can be at least one selected from, but not limited to, yellow tobacco leaves, burley tobacco leaves, oriental tobacco leaves, cigar tobacco leaves, and flue-cured tobacco leaves.

[0076] As shown in Figure 1 (a combustion-type aerosol-generating product), the packaging material according to one embodiment of the present invention may include packaging materials for each component of the aerosol-generating product. These materials may include tobacco medium packaging material 120a for wrapping the tobacco medium, filter plug packaging material (filter plug wrap) 110a for wrapping the filter plug, and so on. Furthermore, as mentioned above, when the filter plug portion is comprised of multiple segments, packaging materials for wrapping each segment may be included. Furthermore, to securely connect the tobacco medium and filter plug, tipping paper 130 may be included to wrap a portion of the tobacco medium and the filter plug. Furthermore, to maintain the overall shape of the aerosol-generating product, an outer wrapper may be included to wrap the entire tobacco medium and filter plug, located on the outermost side of the aerosol-generating product.

[0077] Optionally, the tipping paper used to connect the tobacco medium portion and the filter rod may have at least one perforation formed along the circumference 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 transfer amount of mainstream smoke components.

[0078] At the same time, the cooling block according to one embodiment of the present invention can be included in a non-combustion aerosol generating product as shown in FIG. 2 , and its specific position is basically the same as that described in FIG. 1 , including a tobacco medium portion, a filter rod portion, a packaging material, etc.

[0079] The structure and effects of the present invention will be described in more detail below with reference to the following examples and comparative examples. However, these examples are only used to illustrate the present invention in more detail, and the scope of the present invention is not limited thereto.

[0080] - Example

[0081] (1) Preparation Example: Preparation of Cooling Blocks

[0082] Example 1

[0083] To prepare a cooling block according to an embodiment of the present invention, the flavoring ingredients include powdered WS-3 and menthyl lactate, as well as liquid menthone, menthyl acetate, and eucalyptol. The prepared WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol ingredients are mixed with alcohol as a solvent and stirred for a period of time to fully dissolve the flavoring ingredients in the alcohol.

[0084] At this time, the added raw materials and alcohol contents are shown in Table 1 below.

[0085] Example 2

[0086] A cooling block was prepared in the same manner as in Example 1, except that the WS-3 content and the menthone content in the cooling agent were adjusted to 25% by weight and 10% by weight, respectively.

[0087] Comparative Example 1

[0088] A cooling block was prepared in the same manner as in Example 1, except that WS-23 was used instead of WS-3 to dissolve in alcohol. The amount of WS-23 added was 15% by weight of the total weight of the cooling block.

[0089] Comparative Example 2

[0090] A cooling block was prepared in the same manner as in Example 1, except that 4-terpineol was used instead of menthone to dissolve in alcohol. The amount of 4-terpineol added was 20% by weight of the total weight of the cooling block.

[0091] Comparative Example 3

[0092] A cooling block was prepared in the same manner as in Example 1, except that 1,4-cineol was used instead of eucalyptol to dissolve in alcohol. The amount of 1,4-cineol added was 2% by weight of the total weight of the cooling block.

[0093] The types and contents of the cooling agents in the cooling blocks prepared in Examples 1 to 2 and Comparative Examples 1 to 3 are summarized in Table 1 below.

[0094] [Table 1] [distinguish] [WS-3] [Menthyl lactate(] [menthyl] [lactate] [)] [Menthone(] [menthone] [)] [Menthyl acetate(] [menthyl] [acetate] [)] Eucalyptus oil( [eucalyptol] [)] [WS-23] [4-] [Terpineol(] [4-terpineol] [)] [1] [,] [4-] [Cineole(] [1] [,] [4-cineol] [)] [Alcohol] [Example] [1] 15 35 20 5 2 0 0 0 twenty three [Example] [2] 25 35 10 5 2 0 0 0 twenty three [Comparative Example] [1] 0 35 20 5 2 15 0 0 twenty three [Comparative Example] [2] 15 35 0 5 2 0 20 0 twenty three [Comparative Example] [3] 15 35 20 5 0 0 0 2 twenty three (The numerical units in Table 1 are all weight %)

[0095] (2) Test Example 1: Sensory evaluation of the prepared cool taste block

[0096] A 16-person evaluation panel from KT&G R&D evaluated the intensity of the aroma, cooling sensation of menthol, ease of swallowing, flavor intensity, overall balance, refreshing aftertaste, and satisfaction after inhaling aerosol-generating products containing the cooling blocks prepared in Examples 1 to 2 and Comparative Examples 1 to 3, with a maximum score of 9. The evaluation results were averaged and are shown in Table 2 below.

[0097] [Table 2] [distinguish] [Flavor intensity] [Menthol cooling sensation] [Swallowing Softness] [Fragrance intensity] [Overall sense of balance] [Aftertaste refreshing degree] [Satisfaction] [Example] [1] 4.23 5.03 4.54 5.17 5.24 5.22 5.14 [Example] [2] 4.20 4.61 4.12 4.53 4.67 4.62 4.56 [Comparative Example] [1] 3.54 4.54 4.08 4.51 4.52 4.02 4.08 [Comparative Example] [2] 4.14 4.58 4.53 3.58 4.06 4.53 4.13 [Comparative Example] [3] 4.13 4.02 4.14 4.01 4.07 3.58 3.87

[0098] Referring to Table 2, the evaluation results of Examples 1 and 2, which contain all of WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol, show superior results in terms of aroma intensity, menthol cooling sensation, fragrance intensity, overall balance, refreshing aftertaste, and overall satisfaction compared to Comparative Examples 1 to 3, which lack WS-3, menthone, and eucalyptol.

[0099] More specifically, Comparative Example 1, which lacked WS-3, performed poorly across all evaluation criteria, particularly in aroma intensity and refreshing aftertaste. Comparative Example 2, which lacked menthone, also performed poorly in aroma intensity and overall balance. Comparative Example 3, which lacked eucalyptol, scored lower than the examples in menthol's cooling sensation, aroma intensity, overall balance, and refreshing aftertaste.

[0100] This shows that smokers' overall satisfaction with Examples 1 and 2 is higher than that with Comparative Examples 1 to 3.

[0101] On the other hand, when comparing Examples 1 and 2, which contain different amounts of WS-3 and menthone, Example 2, which contains an excess of WS-3 or a small amount of menthone, is slightly inferior in terms of menthol cooling sensation, swallowing ease, flavor intensity, overall balance, and refreshing aftertaste, resulting in overall lower satisfaction than Example 1.

[0102] (3) Test Example 2: Sensory evaluation with existing tobacco

[0103] An aerosol-generating article comprising the cooling block of Example 1 was compared with the existing EsseChange 1 mg.

[0104] The cooling block prepared in Example 1 is directly sprayed onto the tobacco shreds during the tobacco preparation process, thereby being applied to aerosol-generating products.

[0105] Subsequently, a 13-person evaluation panel from KT&G R&D evaluated the aroma intensity, menthol cooling sensation, swallowing ease, flavor intensity, overall balance, refreshing aftertaste, and satisfaction ratings on a scale of 9. The evaluation results were averaged and are shown in Table 3 below.

[0106] [Table 3] [distinguish] [Flavor intensity] [Menthol cooling sensation] [Swallowing Softness] [Fragrance intensity] [Overall sense of balance] [Aftertaste refreshing degree] [Satisfaction] [existing] 4.04 3.19 5.27 3.42 4.73 5.08 4.92 [Alternative] 4.00 3.23 5.15 3.46 4.54 5.04 4.88

[0107] Comparison of aerosol-generating articles comprising the cooling block of Example 1 with conventional ESSE Change 1 mg

[0108] A 16-person evaluation panel at KT&G R&D in Beijing inhaled 1 mg of EsseChange (a prototype; menthol and cooling blocks were not mixed in the secondary flavoring when preparing EsseChange 1 mg) and the aerosol-generating product containing the cooling blocks of Example 1, and then evaluated the results using the same method described above. The average values ​​of the evaluation results are shown in Table 4 below.

[0109] [Table 4] [distinguish] [Flavor intensity] [Menthol cooling sensation] [Swallowing Softness] [Fragrance intensity] [Overall sense of balance] [Aftertaste refreshing degree] [Satisfaction] [conventional] 4.04 2.71 4.93 2.86 4.57 5.00 5.00 [Alternative] 3.86 3.18 5.29 3.93 4.96 5.07 5.07

[0110] Comparison of the aerosol-generating product containing the cooling block of Example 1 with the existing Raison French Black

[0111] A 16-person evaluation panel from KT&G R&D evaluated the effects of both the existing Raison French Black and the aerosol-generating product containing the cooling block of Example 1 using the same method described above. The average of the evaluation results is shown in Table 5 below.

[0112] [Table 5] [distinguish] [Flavor intensity] [Menthol cooling sensation] [Swallowing Softness] [Fragrance intensity] [Overall sense of balance] [Aftertaste refreshing degree] [Satisfaction] [existing] 3.91 3.66 4.59 4.19 4.56 4.38 4.56 [Alternative] 4.16 4.00 4.72 4.41 4.88 4.72 5.03

[0113] The results of Test Example 2 indicate that the aerosol-generating product containing the cooling block according to an embodiment of the present invention provides superior menthol cooling sensation, refreshing aftertaste, and overall satisfaction compared to existing aerosol-generating products such as ESSE Change 1mg, conventional ESSE Change 1mg, and Raison French Black. This cooling block can complement the taste acceptance and satisfaction of existing menthol products and better reflect multiple sensory characteristics.
