Description

Smoking article with improved scent persistence and manufacturing method thereof

The present disclosure relates to a smoking article with improved scent persistence and a method for manufacturing the same. More particularly, it relates to a smoking article in which fragrance persistence is improved by applying a perfume sheet or a composition thereof to a wrapper region, and a method for manufacturing the smoking article.

To satisfy smokers' preferences, smoking articles (e.g. cigarettes) are subjected to flavoring treatment in various ways. An example of a typical fragrance treatment method is the direct addition (e.g. spraying) of a fragrance liquid to a smoking material such as cut filler or a filter plug. However, the exemplified methods have various problems, such as a limitation in the amount of fragrance added, the intended fragrance not being expressed, or a sharp drop in fragrance expression during smoking.

Specifically, in the method of adding the hyangaek to the smoking material, it is difficult to add a large amount of the hyangaek because the hyangaek may coagulate with the smoking material. In addition, an unintended fragrance may be expressed as the hyangaek deteriorates due to a high heating temperature (or combustion temperature) during smoking. Next, the method of adding the hyangaek to the filter plug may add a large amount of hyangaek compared to the above-described method, but this also has a limit in the amount of addition.

On the other hand, there is a problem in that the added hyangaek is rapidly expressed in the early stage of smoking in any way, and thus the fragrance expression decreases toward the latter part of smoking. problems may arise.

A technical problem to be solved through some embodiments of the present disclosure is to provide a smoking article with enhanced scent persistence.

Another technical problem to be solved through some embodiments of the present disclosure is to provide a method of manufacturing a smoking article with enhanced scent persistence.

The technical problems of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

To solve the above technical problem, a smoking article according to some embodiments of the present disclosure may include a smoking material unit, a filter unit, and a wrapper surrounding at least a portion of the smoking material unit. In this case, a fragrance sheet including a hydrocolloid material and a fragrance may be applied to the wrapper.

In some embodiments, the perfume sheet may be used as the wrapper.

In some embodiments, the thickness of the perfume sheet may be 40 μm to 150 μm.

In some embodiments, the perfume sheet may be attached to the inside of the wrapper.

In some embodiments, at least a portion of the wrapper may be made of a metal foil, and the perfume sheet may be disposed inside the metal foil.

In some embodiments, the composition of the perfume sheet may be coated on the inside of the wrapper.

In order to solve the above technical problem, a method for manufacturing a smoking article according to some embodiments of the present disclosure is prepared by using a perfume composition including a hydrocolloid material and a perfume or a perfume sheet prepared from the perfume composition and wrapping at least a portion of the smoking material portion with the prepared wrapping material to manufacture a smoking article including the smoking material portion.

In some embodiments, the manufacturing step may include laminating the perfume sheet and the wrapping paper by spraying a liquid having no adhesive or non-adhesive properties.

In some embodiments, the manufacturing step may include applying the perfume composition to a wrapping paper and drying it.

According to some embodiments of the present disclosure described above, a perfume sheet or a composition thereof may be applied to a wrapper portion of a smoking article. Here, the perfume sheet is a material manufactured in a solid phase, and unlike the hyangaek, it can well withhold the volatilization of the perfume, effectively solving the problem of most of the flavor being expressed in the early stage of smoking. can be Not only that, but by doing so, the addition amount of the fragrance, the position of addition, and the like can be precisely controlled. For example, the method of applying the fragrance sheet to the wrapper is easier to control the amount of fragrance added than the method of applying the cut pieces of the fragrance sheet to the smoking material part (e.g. the cut pieces of the fragrance sheet are combined with cut vinegar), and the position of fragrance expression is controlled. It also has the advantage of being easy to do.

In addition, the wrapping paper of the smoking article and the fragrance sheet are laminated, or the composition of the fragrance sheet is applied on the wrapping paper, whereby the wrapping material of the smoking article can be easily manufactured. In addition, using the manufactured wrapping material has an advantage that smoking articles can be manufactured using existing manufacturing equipment (ie, equipment for wrapping smoking articles) as it is.

In addition, since the hydrocolloid material is included in the perfume sheet, the perfume sheet can be easily attached to the wrapper site without an adhesive. For example, the perfume sheet and the wrapping paper can be easily laminated without an adhesive. Accordingly, the manufacturing process of the wrapping material can be simplified, and can be free from safety problems caused by the adhesive.

The wrapper 130 may be made of porous or non-porous wrapping paper, but the scope of the present disclosure is not limited thereto. For example, the wrapper 130 may be formed of a metal foil or a laminated form of a wrapping paper and a metal foil.

According to various embodiments of the present disclosure, as shown, the perfume material (10, hereinafter, “fragrance sheet”) manufactured in the form of a sheet is a smoking material unit 110 or a wrapper 130 of the filter unit 120 . can be applied to As the perfume sheet 10 applied in this way continuously expresses the scent during smoking, it is possible to increase the scent expression and scent persistence of the smoking article 100 . That is, the perfume sheet is a material manufactured in a solid phase, and unlike the hyangaek, it can well withhold the volatilization of the perfume, so that it is possible to effectively solve the problem that most of the flavor is expressed in the early stage of smoking. However, the specific application method may be different.

In some embodiments, as shown in FIG. 2 , the perfume sheet 10 may be disposed on the inside of the wrapper 130 (e.g. attached (laminated), coated). 2 shows as an example that the fragrance sheet 10 completely surrounds the smoking material unit 110 , but this is only for convenience of understanding, and the fragrance sheet 10 is the smoking material unit 110 . It may be arranged in the form of enclosing a part. In addition, when at least a portion of the wrapper 130 is made of a metal foil, the perfume sheet 10 may be disposed inside the metal foil. In this case, the fragrance expression of the perfume sheet 10 may be further promoted by the heat transferred through the metal foil. The process of disposing the perfume sheet 10 on the wrapper 130 will be described later with reference to FIGS. 7 and 8 .

In some embodiments, as shown in FIG. 3 , the perfume sheet 10 may constitute at least a portion of the wrapper 130 . That is, the perfume sheet 10 may function as the wrapper 130 of the smoking article 100 . At this time, at least a portion of the wrapper 130 may be configured only with the perfume sheet 10 , or may be configured in a form in which the perfume sheet 10 and the rapping paper are integrated. In this case, there is no need to perform a process (e.g. attaching (laminating) process, coating process) of arranging the perfume sheet 10 on the wrapper 130, so that the manufacturing process of the smoking article 100 can be more simplified. .

Meanwhile, according to some embodiments of the present disclosure, the perfume sheet 10 may be applied to a portion other than the wrapper 130 . For example, as shown in FIG. 4 , the perfume sheet 10 may be applied inside the smoking material unit 110 . More specifically, the flavoring sheet 10 may be put into the smoking material unit 110 together with the tobacco sheet 20 (e.g. tobacco material in the form of a sheet such as a plate leaf). For example, the perfume sheet 10 may be attached to the tobacco sheet 20 and put into the smoking material unit 110 .

The composition material, composition ratio, thickness, manufacturing method, etc. of the perfume sheet 10 may be designed in various ways, and some examples thereof will be described later.

So far, the smoking article 100 according to some embodiments of the present disclosure has been described with reference to FIGS. 1 to 4 . As described above, the perfume sheet 10 may be applied to the portion of the wrapper 130 of the smoking article 100 . The perfume sheet 10 is a material manufactured in a solid phase, and unlike the hyangaek, it can well withhold the volatilization of the perfume, so that it is possible to effectively solve the problem that most of the flavor is expressed in the early stage of smoking, and accordingly, the flavor of the smoking article 100 Durability can be greatly improved. In addition, the method of applying the fragrance sheet 10 to the wrapper is higher than the method of applying the cut pieces of the fragrance sheet 10 to the smoking material unit 110 (e.g. the cut pieces of the fragrance sheet are combined with cut filler). It is easy to control, and it has the advantage of being easy to control the position of the fragrance expression.

Hereinafter, smoking articles 200 and 300 with improved fragrance lasting according to some embodiments of the present disclosure will be described with reference to FIGS. 5 and 6 . However, for clarity of the present disclosure, a description of the content overlapping with the smoking article 100 described above will be omitted.

5 is an exemplary view illustrating a smoking article 200 with enhanced scent persistence according to some other embodiments of the present disclosure.

As shown in FIG. 5 , the smoking article 200 may include a smoking material unit 210 and a filter unit 220 , and the filter unit 220 may include a plurality of segments 221 and 222 . have.

The smoking material unit 210 may correspond to the smoking material unit 110 described above. Therefore, a description thereof will be omitted.

Next, the filter unit 220 may include a first segment 221 and a second segment 222 . Of course, the filter unit 220 may further include a third segment (not shown).

The first segment 221 may perform a cooling function for smoke and/or aerosol generated by the smoking material unit 210 . Accordingly, the first segment 221 may be referred to as a "cooling segment 221" in some cases.

The first segment 221 may be manufactured in various shapes. As an example, the first segment 221 may be a cylindrical paper tube formed of a paper material and including a hollow. As another example, the first segment 221 may be made of a polymer material or a biodegradable polymer material. For example, the first segment 221 may be made of polylactic acid (PLA) fiber, but is not limited thereto. As another example, the first segment 221 may be made of a cellulose acetate filter having a plurality of holes. As another example, the first segment 221 may be a tube filter including a hollow. For example, the first segment 221 may be a cellulose acetate filter including a hollow. However, the present invention is not limited thereto, and if the cooling function can be performed, the first segment 221 may be manufactured in a form different from that illustrated.

In some embodiments, the perfume sheet 10 may be applied to the first segment 221 . For example, the perfume sheet 10 may be disposed in a rolled shape in the hollow of the first segment 221 or may be attached to the hollow inner wall. As another example, the perfume sheet 10 processed (e.g. punching) to form a plurality of holes may be disposed in the hollow in a rolled shape. In this case, an airflow path may be easily secured through a plurality of holes, and a cooling effect may also be improved due to an increase in the contact area between the perfume sheet 10 and the airflow.

Next, the second segment 222 may perform a filtering function for smoke and/or aerosol that has passed through the first segment 221 . Accordingly, the second segment 222 may be referred to as a “filter segment 222” in some cases. Alternatively, the second segment 222 may be referred to as a “mouthpiece segment 222” because the second segment 222 is positioned at the mouthpiece.

In some embodiments, the second segment 222 may include at least one capsule 240 . Here, the capsule 240 may perform a function of generating a flavor or may perform a function of generating an aerosol. For example, the capsule 240 may have a structure in which a liquid containing a fragrance is wrapped with a film. In addition, the capsule 240 may have a spherical or cylindrical shape, but is not limited thereto.

Next, the wrapper 230 may correspond to the wrapper 130 described above. Therefore, a description thereof will be omitted. As mentioned above, the perfume sheet 10 may be applied to the wrapper 230 . By doing so, the scent persistence of the smoking article 200 can be greatly improved.

Meanwhile, although not shown in FIG. 5 , the smoking article 200 may further include a plug (not shown) disposed at the distal end. For example, the plug may be disposed at the upstream end of the smoking article 200 to perform a function of appropriately adjusting the overall length of the smoking article 200 . In addition, when the smoking article 200 is inserted into the aerosol-generating device (not shown), the plug may perform a function of adjusting the smoking material unit 210 to be disposed at an appropriate position inside the aerosol-generating device.

6 is an exemplary diagram schematically illustrating a smoking article 300 according to still some other embodiments of the present disclosure.

As shown in FIG. 6 , the smoking article 300 may include a smoking material unit 310 and a filter unit 320 , and each of the smoking material unit 310 and the filter unit 320 includes a plurality of segments ( 311, 312, 321, 322).

As illustrated, the smoking material unit 310 may include a first segment 311 and a second segment 312 . Of course, the smoking material unit 310 may further include a third segment (not shown).

The first segment 311 may include a moisturizer. For example, the first segment 311 may comprise crimped paper impregnated with a humectant. The humectant may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

Next, the second segment 312 may include a nicotine generating substrate, such as tobacco material. The nicotine generating substrate may include, for example, tobacco cut filler, tobacco particles, tobacco sheets, tobacco beads, tobacco granules. As another example, the nicotine generating substrate may include crimped paper impregnated with tobacco extract. When the nicotine-generating substrate is heated, nicotine may be generated from the nicotine-generating substrate and the nicotine may be transferred to the filter unit 320 .

Next, the filter unit 320 may also include a plurality of segments 321 and 322 . For example, the filter unit 320 may include a third segment 321 performing a cooling function and a fourth segment 322 performing a filtering function. Since the above-described contents of the filter unit 220 of FIG. 5 may be equally applied to the filter unit 320, further description will be omitted.

Next, the wrapper 330 may correspond to the wrapper 130 described above. Therefore, a description thereof will be omitted. As mentioned above, the perfume sheet 10 may be applied to the wrapper 330 . By doing so, the scent persistence of the smoking article 300 can be greatly improved.

So far, smoking articles 200 and 300 according to some other embodiments of the present disclosure have been described with reference to FIGS. 5 and 6 . Hereinafter, the fragrance sheet 10 and a method for manufacturing the same according to some embodiments of the present disclosure will be briefly described.

The perfume sheet 10 may be manufactured through the steps of preparing a perfume composition in a liquid phase (e.g. a slurry state) and molding the prepared perfume composition into a sheet form and drying the perfume composition. Here, the liquid phase may include a mixed state (e.g. slurry state) of a liquid and a solid as well as a liquid state. For example, the perfume sheet 10 may be manufactured by stretching (casting) the perfume composition on a predetermined substrate and drying the perfume composition. However, the present invention is not limited thereto, and a specific manufacturing method may be different.

Meanwhile, the detailed composition of the perfume composition may be designed in various ways.

In some embodiments, the perfume composition may include distilled water, a hydrocolloid material, and a perfume. The fragrance sheet 10 prepared from such a fragrance composition has excellent fragrance retention, and can greatly improve fragrance expression and fragrance persistence of smoking articles (e.g. 100). In addition, due to the hydrocolloid material, the perfume sheet 10 can be attached to the wrapper (e.g. 130) without a separate adhesive, so that the arrangement process of the perfume sheet 10 can be simplified, and it can be free from safety problems due to the adhesive have.

Distilled water may be a factor for controlling the viscosity of the slurry-type perfume composition.

The hydrocolloid material may be a material for coating and fixing the perfume, and a sheet former for forming a sheet. Examples of hydrocolloid materials include gelatin, agar, gellan gum, pectin, guar gum, xanthan gum, glucomannan, hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), ethylcellulose (EC), carboxymethylcellulose (CMC) , starch, and the like, but are not limited thereto.

Examples of flavoring include menthol, nicotine, nicotine salt, tobacco leaf extract, leaf tobacco extract containing nicotine, natural plant flavoring (e.g. cinnamon, sage, herbs, chamomile, reeds, chamomile, cloves, lavender, cardamom, cloves, nutmeg, bergamot , geranium, honey essence, rose oil, lemon, orange, cinnamon, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang ylang, fennel , anise, licorice, St. John's bread, plum extract, peach extract, etc.), sugars (e.g. glucose, fructose, isomerized sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (e.g. isoacetate) Wheat, linaryl acetate, isoamyl propionate, linaryl butyrate, etc.), ketones (e.g. menthone, ionone, damasenon, ethyl maltol, etc.), alcohols (e.g. geraniol, linalol, anetol, oh genol, etc.), aldehydes (e.g. vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g. γ-undecalactone, γ-nonalactone, etc.), animal fragrances (e.g. musk, ambergris, civet, castrium) etc.), hydrocarbons (e.g. limonene, pinene, etc.) are mentioned. The perfume may be used as a solid, or it may be used after being dissolved or dispersed in an appropriate solvent, for example, propylene glycol, ethyl alcohol, benzyl alcohol, or triethyl citrate. In addition, fragrances that are easily dispersed in a solvent by addition of an emulsifier, for example, hydrophobic fragrances, oil-soluble fragrances, and the like can be used. These perfumes may be used alone or may be used as a mixture. However, the scope of the present disclosure is not limited by the above-described examples.

In some embodiments, the perfume composition may include modified cellulose among various hydrocolloid materials. Here, "modified cellulose" may refer to cellulose in which a specific functional group is substituted in the molecular structure. Examples of modified cellulose may include, but are not limited to, HPMC, MC, CMC, and EC. For example, HPMC may have a grade within the range of about 4 to 40000 depending on the ratio and molecular weight in which the hydroxypropyl group and the methyl group (or methoxy group) are substituted. Depending on the grade, the viscosity of the modified cellulose can be determined. More specifically, the physicochemical properties of HPMC are related to the ratio of methoxy groups, the ratio of hydroxypropyl groups, and molecular weight. It can be classified as HPMC1828, HPMC2208, HPMC2906 and HPMC2910. Here, the first two numbers may mean a ratio of a methoxy group, and the latter two numbers may mean a ratio of a hydroxypropyl group. As a result of continuous experiments by the present inventors, it was confirmed that the perfume sheet 10 prepared from the perfume composition including the modified cellulose was excellent in sheet physical properties and flavor retention.

In addition, in some embodiments, the perfume composition may further include LM-pectin (low methoxyl pectin). Alternatively, the perfume composition may include LM-pectin in the hydrocolloid material as a sheet former. LM-pectin is low-ester pectin or low methoxyl pectin in which esterification is relatively low, and specifically, it may refer to pectin containing less than about 50% of carboxyl groups in the molecular structure. Unlike carrageenan, LM-pectin has a characteristic that it does not gel when cooled, so it is possible to lower the viscosity of the slurry-type perfume composition (e.g. about 600 cp to 800 cp). In addition, it is possible to prepare a slurry-type perfume composition without an emulsifier, thereby being free from safety problems due to the emulsifier.

LM-pectin may contain less than about 50%, less than about 40%, less than about 30%, less than about 20%, or less than about 10% of carboxyl groups within the molecular structure. As the content of carboxyl groups in the molecular structure of LM-pectin decreases, the viscosity of the slurry containing LM-pectin may decrease.

Also, in some embodiments, the perfume composition may further include a bulking agent. The bulking agent may increase the total mass (ie, dry matter mass) of components other than distilled water, thereby increasing the volume of the fragrance sheet 10 to be manufactured, and does not affect the original function of the fragrance sheet 10 . It may be a substance. Specifically, the bulking agent increases the volume of the perfume sheet 10 , and at the same time does not substantially increase the viscosity of the slurry, it may have a characteristic that does not adversely affect the perfume retention function of the perfume sheet 10 . Preferably, the bulking agent may be starch, modified starch, or starch hydrolyzate. However, the present invention is not limited thereto.

Modified starch refers to starch acetate, oxidized starch, hydroxypropyl phosphate starch, hydroxypropyl starch, phosphate distarch, monostarch phosphate, phosphate diphosphate starch, and the like.

A starch hydrolyzate refers to the substance obtained by the process including the process of hydrolyzing starch. The starch hydrolyzate may include, for example, a substance obtained by directly hydrolyzing starch (ie, dextrin), or a substance obtained by hydrolyzing starch after heat treatment (ie, indigestible dextrin). The bulking agent may be, for example, dextrin, and more specifically, cyclodextrin.

The starch hydrolyzate may generally be a starch hydrolyzate having a DE value in the range of about 2 to about 40, preferably a starch hydrolyzate having a DE value in the range of about 2 to about 20. As a starch hydrolyzate having a DE value in the range of about 2 to about 20, for example, Finedex #100 (Matsutani Chemical Industry Co., Ltd.), Fine Fiber (Matsutani Chemical Industry Co., Ltd.), TK -16 (Matsutani Chemical Industry Co., Ltd.) can be utilized.

Here, "DE" is an abbreviation for dextrose equivalent, and the DE value represents the degree of hydrolysis of starch, that is, the saccharification rate of starch. In the present disclosure, the DE value may be a value measured by a Willstatter-Schudel method. The properties of the hydrolyzed starch (starch hydrolyzate), for example, the molecular weight of the starch hydrolyzate and the arrangement of sugar molecules constituting the starch hydrolyzate, are not constant for each molecule of the starch hydrolyzate, and a certain distribution or It exists with variations. Depending on the distribution and variation of the properties of the hydrolyzate of starch, or the difference in cut sections, the hydrolyzate of starch may exhibit different physical properties (eg, DE value) for each molecule thereof. As described above, starch hydrolyzate is a set of molecules exhibiting different physical properties, but the measurement result (ie, DE value) by the Willstatter-Schudel method is a representative value indicating the degree of hydrolysis of starch. is being handled.

Preferably, the starch hydrolyzate may be selected from the group consisting of a dextrin having a DE value of from about 2 to about 5, an indigestible dextrin having a DE value of from about 10 to about 15, and mixtures thereof. As the dextrin having a DE value of about 2 to about 5, for example, Finedex #100 (Matsutani Chemical Industry Co., Ltd.) may be utilized. As the indigestible dextrin having a DE value of about 10 to about 15, for example, fine fiber (Matsutani Chemical Industry Co., Ltd.) can be utilized.

Also, in some embodiments, the perfume composition may further include a plasticizer. The plasticizer may improve the physical properties of the perfume sheet 10 by adding appropriate flexibility to the sheet 10 . The plasticizer may include, for example, at least one of glycerin and propylene glycol, but is not limited thereto.

Also, in some embodiments, the perfume composition may further include an emulsifier. The emulsifier may increase the amount of fragrance retention of the fragrance sheet 10 by allowing the oil-soluble fragrance and the water-soluble hydrocolloid material to be well mixed. Examples of the emulsifier may include, but are not limited to, lecithin.

Meanwhile, the perfume sheet 10 prepared from the aforementioned perfume composition may have various content ratios (composition ratios).

In some embodiments, the perfume sheet 10 may include, based on 100 parts by weight in total, about 2 to about 15 parts by weight of moisture, about 25 to about 90 parts by weight of modified cellulose, and about 0.1 to about 60 parts by weight of fragrance. can

In addition, in some embodiments, the perfume sheet 10, based on 100 parts by weight in total, about 2 to about 15 parts by weight of moisture, about 1 to about 60 parts by weight of a hydrocolloid material, about 1 to about 60 parts by weight of LM-pectin It may contain from about 0.1 to about 60 parts by weight of the fragrance and fragrance.

In some embodiments, the plasticizer may be included in an amount of about 0.1 to about 15 parts by weight based on 100 parts by weight of the fragrance sheet 10 as a whole. A sheet having adequate flexibility within this numerical range can be formed. For example, when too little plasticizer is added, the flexibility of the sheet is low, and the perfume sheet may be easily broken during the process. If too much plasticizer is added, the sheet may not be formed well.

Experimental Example 1: Ease of manufacture and characteristic evaluation

For the perfume sheet, wrapper and cigarette according to Examples 1 to 7, an experiment was conducted to comprehensively evaluate the preparation easiness of crude liquid (ie, perfume composition), manufacturing easiness, quality characteristics such as appearance, perfume retention characteristics, and sensory characteristics during smoking did. Evaluation of sensory characteristics was performed on a panel with more than 5 years of smoking experience, and evaluation was performed according to the following three grades, and the evaluation results are shown in Table 2 below.

○: Excellent

△: good

X: bad

evaluation item Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 Ease of preparation of crude liquid ○ ○ ○ ○ ○ ○ ○ Ease of Manufacture of Sheets and Wrappers △ ○ ○ ○ ○ ○ ○ Quality characteristics such as appearance ○ ○ ○ ○ ○ △ △ Flavor retention properties △ △ ○ △ ○ ○ ○ Sensory characteristics when smoking ○ ○ ○ X ○ X X

Referring to Table 2, all of the perfume sheets according to the Examples were evaluated to be excellent in the preparation of the crude liquid, the sheet, and the wrapper.

In addition, the perfume sheets according to Examples 6 and 7 were evaluated to be somewhat inferior in quality characteristics compared to other Examples. In other words, the perfume sheet prepared based on gellan gum and gellantine was evaluated to have somewhat inferior quality characteristics compared to the perfume sheet based on other sheet forming agents (e.g. HPMC, MC, LM-pectin, etc.).

In addition, the perfume sheets according to Examples 4, 6 and 7 were evaluated to have inferior sensory characteristics when smoking compared to other Examples. In detail, it was evaluated that flavoring sheets containing HPMC, gellan gum and gelatin produced off-flavors during smoking, and it was confirmed that the generated off-flavors had a negative effect on tobacco taste (see Experimental Example 2).

Experimental Example 2: Sensory evaluation

An experiment was conducted to evaluate the detailed sensory characteristics of the cigarettes according to Examples 1 to 7 for a panel with more than 5 years of smoking experience. Specifically, tobacco intrinsic taste, menthol refreshing feeling, off-taste and tobacco taste were set as evaluation items, and sensory evaluation was performed on a 7-point scale. The evaluation results are shown in Table 3 below. For reference, a higher score means a negative evaluation, and in the case of other items, a higher score means a positive evaluation.

evaluation item Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 tobacco flavor 5.3 5.2 5.2 3.8 5.1 4.5 3.3 Menthol refreshing feeling 3.5 4.0 5.5 3.5 5.6 3.5 3.5 hobbies 3.2 3.1 3.1 5.1 3.5 4.6 6.2 Tobacco taste clean 5.0 5.2 5.5 3.3 4.8 3.8 2.5

Referring to Table 3, in the case of the cigarettes according to Examples 4, 6, and 7, it was evaluated that relatively more off-flavors were generated, and these off-flavors were determined to be attributed to HPMC, gellan gum, and gelatin.

In addition, in the case of the cigarettes according to Examples 2, 3 and 5, it was evaluated that the menthol refreshing feeling was relatively better, which means that even if the perfume sheet is applied to the wrapper, the flavor development is sufficiently improved, and MC and LM-pectin This means that the fragrance sheet manufactured based on the fragrance has excellent performance in terms of fragrance retention and fragrance expression.

Experimental Example 3: Ease of manufacture and property evaluation according to sheet thickness

Experiments were conducted to evaluate the ease of manufacture of sheets and wrappers, flavor retention characteristics, and ease of manufacture of cigarettes by varying the thickness of the perfume sheet according to Example 3. Evaluation was carried out according to three grades in the same manner as in Experimental Example 1 above, and the evaluation results are shown in Table 4 below. For reference, the thickness of the sheet may mean the thickness of the perfume sheet itself or the coating thickness after the perfume composition is dried.

evaluation item Sheet thickness on dry basis (μm) 10 40 60 80 100 150 200 300 Ease of Manufacture of Sheets and Wrappers ○ ○ ○ ○ ○ △ △ X flavor retention properties △ △ ○ ○ ○ ○ ○ - Ease of making cigarettes ○ ○ ○ ○ ○ △ △ -

Referring to Table 4, when the thickness of the perfume sheet is about 150 μm or more, it was evaluated that the ease of manufacturing the sheet and wrapper and the ease of manufacturing the cigarette were somewhat inferior. It is considered that this is because as the thickness of the sheet increases, the flexibility decreases.

In addition, when the thickness of the perfume sheet was about 40 μm or less, it was evaluated that the perfume retention property was somewhat inferior. Therefore, it can be seen that it is preferable that the perfume sheet be manufactured to have a thickness of about 40 μm to 150 μm in order to simultaneously secure the perfume retention characteristics and manufacturing easiness.

The configuration and effects of the above-described perfume sheet 10 have been described in more detail through Examples and Experimental Examples so far.
