Description

Technical field

The present invention relates to a flavor-bearing constituent component of a tobacco product, a tobacco product and a method for producing the same.

State of the art

Among the tobacco products including a source of tobacco flavor and aroma such as cut tobacco, there are known an aroma inhalation device, through which the user experiences the taste and aroma when inhaling, and smokeless tobacco, upon consumption of which the user experiences the taste and aroma by placing the product directly into nasal cavity or oral cavity. In general, aroma inhalation devices can be divided into smoking systems based on combustion of tobacco, exemplified by traditional cigarettes, and smoking systems in which there is no combustion.

Such tobacco products must provide users with a stable flavor throughout the entire period of use. However, a problem with such tobacco products is that if a volatile flavor component such as menthol is added to cut tobacco in the form of a solution, the flavor component disappears as a result of long-term storage, that is, the flavoring effect is not long-lasting. To eliminate the problem of the disappearance of the aromatic component during storage, various solutions have been proposed.

For example, Patent Document 1 describes that pre-synthesized vanillin ester is added to cigarette paper or tobacco filler of a cigarette, and the vanillin ester is decomposed at high temperature during smoking to release vanillin and ester flavor components. Also, Patent Document 2 describes the application of a liquid dispersion including tobacco leaf particles to cut tobacco or cigarette paper to create a stable aroma during puffs of cigarette smoke.

DETAILED DESCRIPTION OF THE INVENTION The present invention is described in more detail below, however, the following description is intended to better illustrate the present invention and does not limit the scope of the present invention.

1. Flavor-carrying constituent component,

The flavor-carrying component of a tobacco product includes:

constituent component of a tobacco product and

a flavor composition applied to the constituent component and comprising a flavor retaining agent and a flavoring agent.

Tobacco product

According to the present invention, a tobacco product includes an inhalation product in which the user inhales the aroma, and smokeless tobacco in which the user experiences the aroma by directly introducing the product into the nasal cavity or oral cavity.

An aroma inhalation product includes a aroma source and is any inhalation product in which the user inhales the aroma emitted by the aroma source. The aroma source contained in the aroma inhalation article is preferably a tobacco aroma source. Specific examples of the aroma inhalation product include a combustion smoking product whose aroma reaches the user by burning the aroma source, and a heated non-combustion aroma inhalation product whose aroma reaches the user by heating but not burning the aroma source.

Smokeless tobacco includes a source of aroma and is a product in which the user experiences the aroma emitted by the aroma source upon administration of the product directly into the nasal cavity or oral cavity. The flavor source contained in the smokeless tobacco is preferably a tobacco flavor source. Examples of smokeless tobacco include snuff and chewing tobacco.

Tobacco Product Constituent A “Tobacco Product Constituent” is the base component that carries the flavor composition. Thus, in the following description, a constituent component of a tobacco product is also referred to as a “base component.”

The base component is, for example, tobacco filler. Tobacco filler is a tobacco material that provides the tobacco flavor of a tobacco product. The tobacco filler is, for example, cut tobacco, sheet tobacco material, tobacco granules, or a combination of these materials. Cut tobacco refers to cut pieces of leaf tobacco (dried tobacco leaves) suitable for inclusion in a tobacco product. Tobacco leaf material is a molded mass of tobacco obtained by molding tobacco material, such as cut tobacco or waste tobacco leaves (such as tobacco leaf trimmings or cut tobacco trims) obtained from tobacco leaf processing plants or industrial plants, in the form of a sheet or cut pieces of molded tobacco material. Tobacco pellets is a molded tobacco product obtained by molding tobacco material, such as cut tobacco or waste tobacco leaves (such as tobacco leaf trimmings or cut tobacco trims) obtained from tobacco leaf processing plants or industrial plants, into granular form.

According to the invention, if the base component is a tobacco filler, the flavor-bearing component component is called a “flavor-bearing tobacco filler.” In particular, if the base component is cut tobacco, the flavor-bearing component component is referred to as “flavor-bearing cut tobacco”; if the base component is tobacco leaf material, then the flavor-bearing constituent component is referred to as “flavor-bearing leaf tobacco material,” and if the base component is tobacco granules, then the flavor-bearing constituent component is referred to as “flavor-bearing tobacco granules.”

One example of a flavor-bearing constituent component when tobacco leaf material is used as the base component is shown in FIG. 1. In FIG. 1 shows a flavor-bearing tobacco sheet material 1, in which a flavor composition 1b is applied to the tobacco sheet material 1a. Since the tobacco sheet material 1a has pores, the flavor composition 1b penetrates into the pores of the tobacco sheet material 1a, as shown in FIG. 1.

Alternatively, the base component may be cigarette paper. Cigarette paper is a paper for wrapping tobacco filler in a product for inhaling flavor. According to the invention, if the base component is cigarette paper, the flavor-bearing constituent component is called “flavor-bearing cigarette paper”.

Alternatively, the base component may be a filter. In particular, the base component may be a filter material (eg, cellulose acetate fibers, paper or film) forming the filter, or the base component may be a ficelle wrapped around the filter material.

Alternatively, the base component may be a flavor filler base material. A flavor filler is a material in which a flavoring agent is applied to a base material, such as film, granules or metal foil, and which is used as a source of flavor along with the tobacco filler of a tobacco product. The flavor filler base material does not include tobacco material, and serves as a flavor carrier.

The aroma filler base material is preferably a granular base material. The granular base material may be either an organic material or an inorganic material. As granular base material, it is possible to use, for example, granules of saccharides and/or polysaccharides. Examples of saccharide and/or polysaccharide granules include granules derived from white sugar and starch, white sugar granules, granules derived from lactose and crystalline cellulose, and D-mannitol granules. As saccharide and/or polysaccharide granules, granules sold under a trade name such as NONPAREIL (registered trademark, Freund Corporation) can be used. The average particle diameter of the granular base material is, for example, from 100 to 900 μm. According to the invention, if the base component is a granular base material, the flavor carrier component is called a “flavor-carrying granular base material.”

One example of a flavor-carrying constituent component when granular base material is used as the base material is shown in FIG. 2. In FIG. 2 shows a flavor-carrying granular base material 2, where the flavor composition 2b is applied to the granular base material 2a. Since the flavor-carrying granular base material 2 is spray-dried, the flavor composition 2b is present on the surface of the granular base material 2a in the form of a large number of fine particles, as shown in FIG. 2.

Alternatively, the flavor filler base material is preferably a metal foil. The metal foil may be a thin plate formed from a composite metal material or a single metal material, or it may be a composite metal foil formed from a laminate of metal and another material (eg, paper or film). Examples of thin plates made from a composite metal material or a single metal material include an aluminum foil plate, a copper foil plate, an iron foil plate, and an aluminum alloy foil plate. Examples of composite materials including metal foil include a laminate of aluminum foil and paper, namely aluminum coated paper. Examples of aluminum coated paper include aluminum coated paper obtained by fixing an aluminum foil coating to paper with an adhesive, and aluminum coated paper produced by vapor deposition of aluminum onto paper.

If metal foil is used as the base component, due to the high thermal conductivity of the metal, the flavor composition applied to the metal foil is easily heated during use of the tobacco product (particularly when the product is heated for inhalation), thereby releasing the flavor contained in the flavor composition. According to the invention, if the base component is a metal foil, the flavor carrier component is referred to as a “flavor carrier metal foil.”

Alternatively, the flavor filler base material may be a film. The film can be made from either organic material or inorganic material. The film may be, for example, a polymer film such as polyethylene terephthalate (PET) film. The flavor filler base material may be any other material that can contain the flavor composition, such as paper, sheet or non-woven fabric, and the choice of its composition or form is not particularly limited.

Flavor Composition The “flavor composition” is applied to a base component and includes a flavor retaining agent and a flavoring agent. The flavor composition can be prepared by applying a liquid composition including a flavor retaining agent, a flavoring agent, and a solvent to a base component and then drying the base component with the liquid composition applied thereto. Accordingly, the flavor composition is a dried composition formed on a base component, namely, a solid composition; the composition may also be referred to as a "fragrance application area". Drying can be carried out until the liquid composition is visually solidified and the solvent can either be completely removed or some of the solvent can remain.

The "flavor retaining agent" is preferably a flavor retaining agent soluble in an organic solvent. In one embodiment, the flavor retention agent is preferably a polysaccharide, and more preferably a polysaccharide that is soluble in an organic solvent. In another embodiment, the flavor retention agent is preferably a cellulose derivative, and more preferably a cellulose derivative that is soluble in an organic solvent. As used herein, a cellulose derivative refers to a derivative obtained by introducing a substituent on the OH group of cellulose, and examples of cellulose derivatives include ethyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methyl cellulose (eg, hydroxypropyl methyl cellulose modified to be hydrophobic). Typically, cellulose derivatives are widely used as binders, film-forming agents and gelling agents that undergo complex interactions based on the characteristic functional group of the derivative. As used herein, the term “organic solvent” in the expression “soluble in an organic solvent” is, for example, ethanol. If a flavor retaining agent soluble in an organic solvent is used as the flavor containing agent, the solvent in the liquid composition is an organic solvent.

The cellulose derivative is preferably an amphiphilic cellulose derivative, and more preferably hydroxypropylcellulose. The degree of substitution of hydroxypropyl cellulose is, for example, from 0.1 to 4.5, preferably from 2.0 to 4.5. According to the invention, the degree of substitution of hydroxypropylcellulose is the number of hydroxypropyl groups in one glucose residue. As the hydroxypropyl cellulose, a product sold under a trade name such as CELNY sold by Nippon Soda Co., Ltd. can be used.

The advantages of using hydroxypropylcellulose as a flavor retention agent are described below. Hydroxypropylcellulose is a derivative of cellulose and is a substance obtained by replacing the OH groups in cellulose with hydroxypropyl groups. Hydroxypropylcellulose is widely used as a binder, film-forming agent and gelling agent. Cellulose is a hydrophobic substance because the OH groups are linked by hydrogen bonds formed between the molecules during crystallization of the substance. On the other hand, hydroxypropyl cellulose contains hydroxypropyl groups, which hinder the formation of hydrogen bonds between molecules and is thus a substance that has both hydrophilic and hydrophobic properties (i.e., an amphiphilic substance).

It has been shown that in a system containing glycerol and hydroxypropylcellulose, interaction (formation of hydrogen bonds) occurs between the hydroxypropyl groups of hydroxypropylcellulose and the OH groups of glycerol, which leads to the formation of a complex with a network structure. Even when a flavor other than glycerol is used, it is believed that hydroxypropyl cellulose can form a complex having a network structure upon interaction (hydrogen bonding, hydrophobic interaction, etc.) with the flavor. In addition, since hydroxypropylcellulose is an amphiphilic substance, it is believed that both the hydrophilic flavor and the hydrophobic flavor can be incorporated into the network structure without the addition of an emulsifier or the like. It is believed that this network-structured complex promotes stable retention of the flavor without evaporation during storage of the tobacco product, and also promotes stable release during use of the tobacco product (particularly when the product is heated to inhale the flavor).

In addition, hydroxypropylcellulose is soluble in organic solvents, in particular ethanol. Thus, if a liquid composition containing hydroxypropylcellulose, flavor and solvent is prepared as an ethanol solution, the viscosity of the ethanol solution can be lower than the viscosity of the aqueous solution, which is advantageous over the aqueous solution in terms of transportation, coating, etc. . during production. When drying an ethanol solution to produce a flavor composition (eg, hydroxypropyl cellulose film), the solvent evaporates faster than in the case of an aqueous solution, resulting in reduced production time as well as lower cost of energy consumed during drying.

The "flavor" contained in a flavor composition is a substance that creates aroma and taste. The flavoring agent may be either a natural or a synthetic flavoring agent. The flavor may include a single flavor or a mixture of flavors. The flavoring agent may be any flavoring agent commonly used in tobacco products (particularly inhalation products). The flavoring agent may be contained in the flavoring composition in such an amount that the flavoring-carrying constituent component can provide the preferred aroma and taste. The flavoring agent may be contained in the flavoring composition in an amount of, for example, from 0.5 to 7000% by weight. by weight of the flavor retaining agent.

A flavoring agent is, for example, a liquid flavoring agent or particles containing a flavoring component. “Liquid flavoring agent” and “particles containing a flavoring component” are described below in that order.

Liquid flavor refers to the flavor present in a liquid state in the liquid composition used as a starting material for preparing the flavor composition.

The liquid flavor may be a liquid flavor containing only the flavor component(s), or it may be a liquid flavor consisting of a solvent and flavor component(s) dissolved or dispersed in the solvent. Examples of the first liquid flavoring agents include glycerin, propylene glycol, 1,3-butanediol, and polyethylene glycol 200. The latter liquid flavoring agent may be a liquid flavoring agent consisting of a water-soluble flavoring agent and water, a liquid flavoring agent consisting of an oil-soluble flavoring agent and an edible oil, or emulsified flavoring agent consisting of oil-soluble flavoring agent and water. Examples of the latter mentioned liquid flavoring agents include essential oils and plant extracts.

The first of said liquid flavorants may be present on the base component in the flavor-bearing constituent component as a liquid, or may be impregnated with the base component in the flavor-bearing constituent component. When using the last mentioned liquid flavoring agent, all solvents may be removed by evaporation from the flavoring component component, or a portion of the solvent may remain in the flavoring component component. If a portion of the solvent contained in the liquid flavor remains in the flavor-carrying component, the liquid flavor may be present as a liquid on the base component, or may be impregnated with the base component.

The liquid flavoring agent may be any liquid flavoring agent typically used in combination with a tobacco flavor source in tobacco products (particularly inhalation products). The liquid flavoring agent is, for example, a polyol. Alternatively, the liquid flavoring agent may be a combination of a polyol and a non-polyol flavoring agent. A polyol is a compound containing many alcohol hydroxyl groups and is also called a polyol. Polyols are, for example, glycerin, propylene glycol, 1,3-butanediol, polyethylene glycol 200 or a combination thereof. In addition to providing aroma and flavor, in the presence of another flavor (ie, a flavor other than the polyol), the polyol can control the release of that flavor. The polyol may be contained in the flavor composition in an amount sufficient to enable the flavor-bearing component to provide the preferred aroma and taste. The polyol may be contained in the flavor composition in an amount of, for example, from 0.5 to 7000 wt%. by weight of the flavor retaining agent.

A "non-polyol flavorant" is generally a substance that creates a flavor. The non-polyol flavoring agent is preferably a liquid non-polyol flavoring agent. As the flavoring agent other than the polyol, any flavoring agent (preferably a liquid flavoring agent) commonly used in tobacco products (particularly a flavor inhalation product) may be used, and preferably any flavoring agent (preferably a liquid flavoring agent) commonly used in combination may be used. with a source of tobacco aroma in tobacco products (in particular, in a product for inhaling aroma). Examples of flavors other than polyol include synthetic flavors such as menthol, jasmonate, maltol, β-ionone, citral, ethyl butyrate and undecalactone; essential oils such as peppermint oil, orange oil, styrax and green tea extracts; extraction essential oil such as vanilla extraction essential oil; plant extracts such as liquid tobacco extract, and combinations thereof. The flavor other than the polyol may be either a natural flavor or a synthetic flavor. The flavor other than the polyol may be a single flavor or a mixture of multiple flavors. A flavor other than a polyol may be contained in the flavor composition in an amount sufficient to enable the flavor-carrying component to provide the preferred aroma and taste. A flavoring agent other than a polyol may be contained in the flavoring composition in an amount ranging from, for example, 0.5 to 7000% by weight. by weight of the flavor retaining agent.

The term "fragrance component containing particles" refers to any particles containing aroma component(s), and such particles are, for example, shredded tobacco leaves or powdered flavoring. The flavor containing particles may be present in a solid state both in the liquid composition used as a starting material for preparing the flavor composition and in the flavor composition.

“Crushed tobacco leaves” are particles obtained by grinding tobacco leaves (ie, dried tobacco leaves used as a source of tobacco flavor in a tobacco product). The average particle diameter of the shredded tobacco leaves may be, for example, from 30 to 120 μm. Grinding can be done using a known grinding mill and can be dry grinding or wet grinding. Accordingly, shredded tobacco leaves may also be referred to as "tobacco leaf particles". According to the invention, the average particle diameter is determined by laser diffraction/scattering method, and it is a value measured by a laser diffraction particle size distribution analyzer (eg, LA-950 supplied by Horiba, Ltd.). Ground tobacco leaves may be contained in the flavor composition in an amount sufficient to permit the flavor-carrying component to provide the preferred aroma and taste. Ground tobacco leaves may be contained in the flavor composition in an amount ranging from, for example, 0.5 to 7000% by weight. by weight of the flavor retaining agent.

"Powdered flavor" is any powdered material containing flavor component(s). The term "powdered flavoring" does not include ground tobacco leaves. The powdered flavor may be either a natural flavor or a synthetic flavor. The powdered flavor may be a single flavor or a mixture of flavors. The powdered flavoring agent may be any powdered flavoring agent commonly used in tobacco products (particularly in inhalation products). The powdered flavor may be, for example, cocoa, or a powder produced by spray drying and atomizing a liquid flavor dispersion. Alternatively, the powdered flavoring agent may be a powder produced by adsorption of the flavoring agent onto fine porous calcium carbonate particles (eg, PORECAL-N, available from Shiraishi Calcium Kaisha, Ltd.) or onto fine porous activated carbon particles (eg, KURARAY COAL, available from Kuraray Co. ., Ltd.). The average particle diameter of the flavor powder may be, for example, from 7 to 80 microns.

In the flavor-carrying component stage, the powdered flavor is present on the base component in particulate form. In the liquid composition stage, the powdered flavor is dispersed in the dispersion medium (the starting material of the flavor composition) and is not dissolved in the dispersion medium. The powdered flavor may be contained in the flavor composition in an amount sufficient to enable the flavor-carrying component to provide the preferred aroma and taste. The powdered flavoring agent may be contained in the flavoring composition in an amount ranging from, for example, 0.5 to 7000% by weight. by weight of the flavor retaining agent. Powdered flavoring can be used in combination with crushed tobacco leaves.

If the flavoring agent is “flavorant-containing particles,” then the flavoring composition may further include a liquid flavoring agent in addition to the flavoring retaining agent and the flavoring-containing particles. The liquid flavor is a substance as described above. For example, along with the flavor retention agent and flavor containing particles (eg, shredded tobacco leaves or powdered flavor), the flavor composition may further include a polyol.

The flavor composition may be present as a coating on the surface of the base component and cover the entire surface of the base component, or it may be present on the base component to cover only a portion of the surface of the base component. The flavor composition may be localized on the surface of the base component (i.e., may be present only on the surface of the base component and not penetrate into the base component), or all of the flavor composition may not necessarily be present on the surface of the base component, and a portion of the flavor composition may penetrate into the base component component.

Preferred Embodiments of the Flavor Composition

In one embodiment, the flavor composition includes hydroxypropylcellulose and a flavor.

First embodiment (embodiment in which the flavor is a liquid flavor)

In a first embodiment, the flavor composition includes hydroxypropylcellulose and a liquid flavor.

In one preferred embodiment, the flavor composition includes hydroxypropylcellulose and a polyol. In a more preferred embodiment, the flavor composition includes hydroxypropylcellulose and glycerin. In another more preferred embodiment, the flavor composition includes hydroxypropylcellulose, glycerin and propylene glycol.

In another preferred embodiment, the flavor composition includes hydroxypropyl cellulose, a polyol, and a non-polyol flavor (preferably a liquid non-polyol flavor). In general, a flavor other than a polyol is a liquid flavor that is used in combination with a tobacco flavor source in a tobacco product (particularly an inhalation product) and which is, for example, menthol. In a more preferred embodiment, the flavor composition includes hydroxypropylcellulose, glycerin and a non-polyol flavor (preferably a liquid non-polyol flavor). In another more preferred embodiment, the flavor composition includes hydroxypropyl cellulose, glycerin, propylene glycol and a non-polyol flavor (preferably a liquid non-polyol flavor).

If a combination of a polyol and a non-polyol flavoring agent is used as the flavoring agent, the polyol may facilitate the release of the non-polyol flavoring agent during use of the tobacco product (particularly during heating of the product for inhalation of the flavor). In this case, by adjusting the ratio between hydroxypropylcellulose and polyol, it is possible to control the release point of the flavor other than the polyol.

Second embodiment (embodiment in which particles including flavor are contained as a flavoring agent)

In a second embodiment, the flavor composition includes hydroxypropyl cellulose and flavor-containing particles (eg, shredded tobacco leaves or powdered flavor).

In one preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, and a polyol. In a more preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, and glycerin. In another more preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, glycerin, and propylene glycol.

In another preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, a polyol, and a liquid flavor other than a polyol. In general, a liquid flavor other than a polyol is a liquid flavor used in combination with a tobacco flavor source in a tobacco product (particularly an inhalation product) and is, for example, menthol. In a more preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, glycerin, and a liquid flavor other than a polyol. In another more preferred embodiment, the flavor composition includes hydroxypropylcellulose, flavor-containing particles, glycerin, propylene glycol, and a liquid flavor other than a polyol.

If a combination of a polyol and a liquid non-polyol flavoring agent is used in addition to the flavor-containing particles, the polyol may facilitate the release of the liquid non-polyol flavoring agent during use of the tobacco product (particularly during heating of the product for inhalation of the flavor). In this case, adjusting the ratio between hydroxypropylcellulose and polyol allows you to control the timing of release of the liquid flavor other than the polyol.

2. Method for producing a flavor-carrying component

The above-described “flavor-bearing component of a tobacco product,” can be produced using a liquid composition as a starting material for preparing a flavor composition. That is, another aspect of the invention relates to a method for producing a flavor-bearing constituent component of a tobacco product, comprising:

applying a liquid composition comprising a flavor retention agent, a flavoring agent and a solvent to the surface of a constituent component of the tobacco product, and

drying the constituent component to which the liquid composition is applied, resulting in a flavor-bearing constituent component.

The "liquid composition" contains a flavor retaining agent, a flavoring agent, and a solvent. “Flavor retention agent” and “flavor” are described in section “1. "Fragrance-carrying constituent component." The solvent is preferably an organic solvent. The use of an organic solvent as a solvent makes it possible to reduce the drying time, which makes it possible to obtain a flavor-bearing component within a short period of time. The organic solvent is, for example, ethanol. If the flavor is a liquid flavor, the flavor retaining agent is dissolved in a solvent, and the solvent is mixed with the liquid flavor. On the other hand, if the flavor is flavor-containing particles, then the flavor-retaining agent is dissolved in a solvent, and the flavor-containing particles are dispersed in the solvent. Thus, if the flavor is particles containing the flavor, then the solvent serves not only as a solvent, but also as a dispersion medium.

The liquid composition may preferably be formulated such that the flavor-carrying constituent component can create a preferred aroma and taste depending on the type of component being mixed (eg, flavoring agent), the type of base component, etc. In the examples described below, the liquid composition may include, for example, from about 15 to about 25 grams of hydroxypropyl cellulose, from about 30 to about 60 grams of ground tobacco leaves, and from about 20 to about 50 grams of glycerin per 100 ml of ethanol. According to the examples described below, the ethanol content of the liquid composition can be, for example, from about 40 to about 70% by weight. According to the examples described below, the weight ratio of hydroxypropyl cellulose to flavor (ground tobacco leaves and glycerin) in the liquid composition can be, for example, from 1: about 2 to 1: about 6.

First, the liquid composition is applied to the surface of the tobacco product component. The “constituent component of a tobacco product” is described in section “1. Flavor-carrying constituent component" and may also be referred to as a "base component" in the following description.

The method of applying the liquid composition to the base component may be any method that ensures uniform application of the liquid composition to the base component, and is not particularly limited in its selection. For example, the liquid composition may be added to or coated on the surface of the base component, the liquid composition may be sprayed onto the surface of the base component, the base component may be dipped into the liquid composition, or the liquid composition may be directly injected into a portion of the base component in tobacco rod through an injector, etc.

Methods by which the liquid composition can be applied to cut tobacco include: directly adding the liquid composition to the surface of the cut tobacco using a pressure pump; spraying the liquid composition onto the cut tobacco using a spray nozzle; or directly injecting the liquid composition into a portion of the cut tobacco in the tobacco rod, through an injector, etc. Alternatively, application of the liquid composition to the cut tobacco may be accomplished by dipping the cut tobacco into the liquid composition.

Methods by which the liquid composition can be applied to the tobacco sheet material include: extruding the liquid composition onto the surface of the tobacco sheet material through a slot die, coating the liquid composition onto the tobacco sheet material using a film coating machine, etc. Alternatively, methods such as spraying and dipping can also be used, following the same approach that can be used when applying to cut tobacco. If the tobacco leaf material is cut, it is preferable to use the same method of applying the composition as for cut tobacco.

Methods by which the liquid composition can be applied to cigarette paper include: extruding the liquid composition through a slot die, coating the liquid composition using a film coating machine, etc., as described above. Alternatively, methods such as spraying and dipping can also be used, following the same approach that can be used when applying to cut tobacco.

If the liquid composition is applied to tobacco granules or granular base material, a granule coating technique may be used. For example, the same methods that coat cut tobacco can be used, such as directly adding the liquid composition to the surface of the tobacco granules or the surface of the granular base material or spraying the liquid composition onto the tobacco granules or granular base material using a spray nozzle.

The amount of liquid composition applied may be suitably determined such that the flavor-carrying constituent component can produce a preferred aroma and taste depending on the composition (i.e., type and amounts of components to be mixed) of the liquid composition, the type of base component, etc. According to the examples described below, if a liquid composition containing shredded tobacco leaves is applied to a tobacco leaf material, the amount of liquid composition applied may be from about 0.1 to about 2 grams per 100 cm ² of tobacco leaf material. According to the examples described below, if a liquid composition containing shredded tobacco leaves is applied to a granular base material, the applied amount of the liquid composition can be from about 50 to about 150 weight percent. parts per 100 mass. parts of granular base material.

The base component to which the liquid composition has been applied is then dried. Drying may continue until the liquid composition visually solidifies and the solvent may be completely removed or may partially remain. Drying is preferably carried out before most of the solvent in the liquid composition has evaporated.

The drying may be natural drying or heat drying. However, if the drying is heat drying, then the heating conditions are preferably selected to preserve the aroma component(s) of the liquid composition. In the case of, for example, hot air drying, the hot air temperature, the hot air volume, the cooling temperature and the cooling air volume are preferably selected such that the aroma component(s) of the liquid composition do not volatilize during heat drying and during cooling after heat drying. heating.

Drying results in the formation of a flavor composition on the base component and a flavor-bearing constituent component. The solvent contained in the liquid composition may be completely removed by evaporation from the flavor-bearing constituent component, or a portion of the solvent contained in the liquid composition may remain in the flavor-bearing constituent component.

Another aspect relates to the flavor-carrying component component obtained by the method described above. Another aspect relates to a method for producing a tobacco product, wherein the method includes producing a tobacco product using a flavor-bearing constituent component obtained by the method described above.

3. Tobacco product

The above-described "flavor-carrying constituent component", such as a flavor-carrying tobacco filler, a flavor-carrying cigarette paper, a flavor-carrying granular base material, or a flavor-carrying metal foil, may be included in a tobacco product. In particular, if the tobacco product is a flavor inhalation product, at least one of a flavor-carrying tobacco filler, a flavor-carrying cigarette paper, a flavor-containing granular base material, or a flavor-carrying metal foil may be included in the inhalation product. aroma. If the tobacco product is smokeless tobacco, at least one of a flavor-bearing tobacco filler, a flavor-bearing granular base material, and a flavor-bearing metal foil may be included in the smokeless tobacco. That is, according to another aspect, the invention relates to a tobacco product including the “flavor-bearing constituent component” described above.

The tobacco product according to the present invention has the same configuration as a conventional tobacco product, except that the component of the conventional tobacco product is replaced by a flavor-bearing constituent component according to the present invention. In one specific embodiment, the tobacco product of the present invention may include at least one of the following elements described above: the above-described “flavor-bearing cut tobacco”, the above-described “flavor-bearing sheet tobacco material”, the above-described “flavor-bearing tobacco granules”, the above-described “flavor-bearing granular base material”, the above-described “flavor-bearing metal foil” and the above-described “flavor-bearing cigarette paper”. The tobacco product of the present invention may include in combination the above-described "flavor-bearing constituent component". For example, the combination may include the above-described “flavor-bearing cut tobacco” and the above-described “flavor-bearing tobacco sheet material”, or the combination may include the above-described “flavor-bearing cut tobacco” and the above-described “flavor-bearing cigarette paper”.

The flavor-carrying constituent component may be included in the tobacco product in any amount. The flavor-bearing constituent component can be used in combination with a component that does not contain a flavor, or it can be used as such rather than in combination with a component that does not contain a flavor. The flavor-bearing cut tobacco, the flavor-bearing tobacco sheet material, the flavor-bearing tobacco granules, the flavor-bearing granular base material and the flavor-bearing metal foil can be added in an amount of, for example, 20 to 100% by weight. by weight of the total tobacco filler, provided that the entire tobacco filler contained in one tobacco product is 100% by weight.

According to one embodiment, the above-described “fragrance-carrying component” can be included in a combustion aroma inhalation product or a heated non-combustion aroma inhalation product. That is, one preferred embodiment relates to a combustion aroma inhalation article or a non-combustion heated aroma inhalation article including the above-described “flavor-carrying constituent component”. The combustion aroma inhalation product is an aroma inhalation product that provides the user with taste and aroma when the aroma source is burned as described above. Also, a non-burning heated aroma inhalation product is a aroma inhalation product that provides the user with taste and aroma by heating but not burning the aroma source.

Examples of combustion inhalation products include a cigarette, a pipe, a kiseru (ie, a traditional Japanese pipe filled with finely cut tobacco), a cigar, and a cigarillo.

The non-combustion heating product for aroma inhalation may be heated by a heating device separate from the product, or it may be heated by a heating device integrated with the product. According to the invention, the combination of the first mentioned non-combustion heated aroma inhalation article and a heating device for such aroma inhalation article (separate) is called a “non-combustion heated smoking system”.

Below, with reference to FIGS. 3-5, one example of a smoking system with heating without combustion is described. Additionally, with reference to FIGS. 6-8 describe one example of a non-combustion heated aroma inhalation product with an integrated heating device.

In fig. 3 and 4 are schematic cross-sectional views of one example of a heated, non-combustion smoking system. In fig. 3 shows article 20 heated without combustion to inhale the aroma before it is introduced into the heating device 10, and FIG. 4 shows the non-combustion heated aroma inhalation article 20 already inserted into the heating device 10 and being heated. In fig. 5 is a cross-sectional view of the article 20 with heating without combustion for aroma inhalation.

As shown in FIG. 3 and 4, the heated non-combustion smoking system includes a heated non-combusted aroma inhalation article 20 and a heating device 10 that externally heats the tobacco containing segment 20A of the heated non-combusted aroma inhalation article 20. The heated non-combustion smoking system is not limited to the configuration shown in FIG. 3 and 4, provided that there is both a non-combustion heating article 20 for aroma inhalation and a heating device 10 for heating the non-combustion heating article 20 for aroma inhalation.

The heating device 10 shown in FIG. 3 and 4, includes a housing 11, a heater 12, a metal tube 13, a battery unit 14 and a control unit 15. The housing 11 includes a cylindrical groove 16, and a heater 12 and a metal tube 13 are located on the inner surface of the groove 16 at a position corresponding to the tobacco-containing segment 20A after the non-combustion heating article 20 is inserted into the groove 16. The housing 11 further includes a ventilation hole 17, which provides communication between the environment located outside the housing 11 and the groove 16 for supplying air to the product 20 with heating without combustion for inhaling the aroma, which is inserted into the groove 16.

The heater 12 may be an electrical resistance heater, and the heater 12 is heated by electric power supplied from the battery unit 14 in accordance with the instructions of the control unit 15, which regulates the temperature.

The heat generated by the heater 12 is supplied to the tobacco containing segment 20A of the non-combustion heating article 20 for aroma inhalation through a metal tube 13 having high thermal conductivity.

In the schematic diagram shown in FIG. 4, a gap is shown between the outer peripheral portion of the non-combustion heated aroma inhalation article 20 and the inner peripheral portion of the metal tube 13, however, it is actually desirable for a gap between the outer peripheral portion of the non-combustion heated aroma inhalation article 20 to effectively transfer heat. and the inner peripheral part of the metal tube 13 was missing.

The heating device 10 heats the tobacco-containing segment 20A of the article 20 without combustion to inhale aroma from the outside, however, it may heat the segment 20A from the inside.

The heating temperature generated by the heating device 10 is not particularly limited, but is preferably 400°C or less, more preferably 150°C or more and 400°C or less, and even more preferably 200°C or more and 350°C or less . The heating temperature is the temperature of the heater 12 of the heating device 10.

As shown in FIG. 5, the heated non-combustion aroma inhalation article 20 (hereinafter referred to as the “aroma inhalation article 20”) has a cylindrical shape. The circumference of the flavor inhalation article 20 is preferably 16 mm to 27 mm, more preferably 20 mm to 26 mm, and even more preferably 21 mm to 25 mm. The overall length (length in the horizontal direction) of the aroma inhalation article 20 is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and even more preferably 50 mm to 60 mm.

The aroma inhalation article 20 is composed of a tobacco containing segment 20A filled with tobacco filler 21, a filter portion 20C forming a mouthpiece, and a connecting portion 20B connecting the tobacco containing segment 20A and the filter portion 20C.

The tobacco containing segment 20A is cylindrical in shape. The overall length (axial length) of the tobacco containing segment 20A is, for example, preferably 20 to 70 mm, more preferably 20 to 50 mm, and even more preferably 20 to 30 mm. The cross-sectional shape of the tobacco containing segment 20A is not particularly limited, and may be, for example, a circle, an ellipse or a polygon.

The tobacco containing segment 20A includes a tobacco filler 21 and a cigarette paper 22 wrapped around the tobacco filler 21. The tobacco filler 21 may include a "flavor-carrying component" according to the present invention, such as a "flavor-carrying cut tobacco", a "flavor-carrying sheet". tobacco material", "flavor-carrying tobacco granules", "flavor-carrying granular base material" or "flavor-carrying metal foil". The cigarette paper 22 may be a flavor-containing cigarette paper according to the present invention.

In addition to the "flavor-carrying component", according to the present invention, the tobacco filler 21 may include a conventional tobacco filler. Conventional tobacco filler may consist of cut tobacco and/or pieces obtained by cutting tobacco sheet material into pieces of a certain width (cut tobacco sheet material). The pieces of the "flavor-bearing cut tobacco" according to the present invention and the "flavor-bearing sheet tobacco material" according to the present invention may be the same size as the pieces of conventional tobacco filler. The tobacco filler 21 may contain an aerosol-forming substance. Examples of aerosol-forming substances include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, and 1,3-butanediol. They can be used alone or in combination of two or more substances.

The filter part 20C has a cylindrical shape. The filter portion 20C includes a rod-shaped first segment 25 formed by filling with cellulose acetate fiber, and a rod-shaped second segment 26 similarly formed by filling with cellulose acetate fiber. The first segment 25 is located on the side of the tobacco containing segment 20A. The first segment 25 may include a hollow portion. The second segment 26 is located on the mouthpiece side. The second segment 26 is continuous. The first segment 25 consists of a first filler layer 25a (cellulose acetate fiber) and an inner ficell 25b wrapped around the first filler layer 25a. The second segment 26 consists of a second layer of filler 26a (cellulose acetate fiber) and an inner ficell 26b wrapped around the second layer of filler 26a. The first segment 25 and the second segment 26 are connected by an outer ficelle 27. The outer ficelle 27 is attached to the first segment 25 and the second segment 26 with a vinyl acetate emulsion adhesive, etc.

The length of the filter portion 20C may be, for example, 10 to 30 mm, the length of the connecting portion 20B may be, for example, 10 to 30 mm, the length of the first segment 25 may be, for example, 5 to 15 mm, and the length of the second segment 26 can be, for example, from 5 to 15 mm. The specified lengths of individual segments are given as an example and may be suitably modified according to product application, required quality, length of tobacco containing segment 20A, etc.

For example, the first segment 25 (segment with a hole in the center) consists of a first filler layer 25a including one or more hollow parts, and an inner ficell 25b covering the first filler layer 25a. The first segment 25 serves to increase the strength of the second segment 26. The first filler layer 25a of the first segment 25 is filled, for example, with high density cellulose acetate fiber. The cellulose acetate fiber is cured by adding, for example, a plasticizer containing triacetin in an amount of 6 to 20% by weight. by weight of cellulose acetate. The inner diameter of the hollow part of the first segment 25 is, for example, from ϕ 1.0 to ϕ 5.0 mm.

The fiber density of the first filler layer 25a of the first segment 25 may be selected, for example, to be relatively high, or it may be equivalent to the fiber density of the second filler layer 26a of the second segment 26, described below. Thus, when inhaled, air or aerosol flows only through the hollow part, and practically no air or aerosol penetrates through the first filler layer 25a. If necessary, for example, to reduce the loss of aerosol components due to filtration in the second segment 26, the length of the second segment 26 can be reduced and the length of the first segment 25 can be increased accordingly.

By replacing the shortened second segment 26 with the first segment 25, the delivered amount of aerosol components is effectively increased. Since the first filler layer 25a of the first segment 25 is composed of filler fiber, the outside touching sensation during use does not cause discomfort to the user.

The second segment 26 consists of a second layer of filler 26a and an inner ficell 26b that covers the second layer of filler 26a. The second segment 26 (filter segment) is filled with cellulose acetate fiber of normal density and is capable of filtering common aerosol components.

The first segment 25 and the second segment 26 may have different filtration properties with respect to the filterable aerosol (the smoke that the smoker inhales) released from the tobacco-containing segment 20A. At least one of the segments, which are the first segment 25 and the second segment 26, may include a flavoring agent. The filter portion 20C may be of any design, which may include a plurality of segments, or may consist of a single segment.

The connecting part 20B has a cylindrical shape. The connecting part 20B includes a paper tube 23 formed into a cylinder, such as thick paper.

A wrapping paper 28 is wrapped in a cylindrical manner around the outer surface of the tobacco containing segment 20A, the connecting portion 20B, and the filter portion 20C, joining them into one unit. The vinyl acetate emulsion adhesive is applied to the entire surface or substantially the entire surface of one of the surfaces (inner surface) of the wrapping paper 28, excluding areas near the portions 24 including the vent holes. The parts 24 including the vent holes are obtained by laser processing the outer surface after joining the tobacco containing segment 20A, the connecting part 20B and the filter part 20C together using wrapping paper 28.

The ventilation hole portion 24 includes two or more through holes that extend through the connection portion 20B in the thickness direction. The two or more through holes are formed such that they are arranged radially when viewed from the central axis of the aroma inhalation article 20. In the described embodiment, the portion 24 including the ventilation holes is located in the connecting portion 20B, however, it may be located in the filter portion 20C. In the described embodiment, two or more through holes in the portion 24 including the ventilation holes are arranged in a line in a row at equal distances on one ring; however, they may be aligned as two equally spaced rows on the two rings, or one or two rows of the vent portion 24 may be aligned in a non-continuous or irregular manner. When the user holds the mouthpiece to take a puff, the air outside the product enters the smoke that the smoker inhales through the vent part 24.

Below with references to Fig. 6-8 describe another example of a non-combustion heated product for flavor inhalation.

In fig. 6 is a perspective view of one example of a product with heating without combustion for aroma inhalation. In fig. 7 is an exploded view of one example of a product with heating without combustion for aroma inhalation. The heated non-combustion aroma inhalation product 30 (hereinafter simply referred to as the aroma inhalation product 30) is an electronic cigarette, nebulizer or the like that generates an aerosol according to the user's inhalations and delivers the aerosol to the user. One continuous breath taken by the user is called a "puff". By means of the aroma inhalation article 30, additional components, such as aroma components, are transported into the resulting aerosol and released into the user's oral cavity.

As shown in FIG. 6 and 7, the aroma inhalation article 30 includes a component body 30A, an aerosol source holding portion 30B, and an additive component holding portion 30C. The main body 30A provides power supply and control of the overall operation of the device. The aerosol source holding portion 30B holds the aerosol source generating an aerosol by spraying. The additive component holding portion 30C holds the tobacco filler 38. The tobacco filler 38 may include a "dampener-bearing component" according to the present invention, such as "flavor-bearing cut tobacco", "flavor-bearing sheet tobacco material", "flavor-bearing tobacco granules", "flavor-carrying granular base material" or "flavor-carrying metal foil". By holding the mouthpiece, which is an end portion located on the side of the additive component containing portion 30C, the user can inhale the aerosol to which a flavoring agent or the like is added.

The user or another person assembles the aroma inhalation article 30 by assembling the main body 30A, the aerosol source holding portion 30B, and the addition component holding portion 30C, etc. The named parts: the main body 30A, the aerosol source holding part 30B, and the additional component holding part 30C are cylindrical, frustoconical or the like having a certain diameter, and the main body 30A, the aerosol source holding part 30B and the additional component holding part 30C can be connected in the order specified. The main body 30A and the aerosol source holding portion 30B are connected to each other, for example, by a screw connection if their end portions are provided with an external thread and an internal thread, respectively. The aerosol source holding portion 30B and the additive component holding portion 30C are connected, for example, by inserting the tapered additive component holding portion 30C into a tubular portion formed at one end of the aerosol source holding portion 30B. The aerosol source holding portion 30B and the auxiliary component holding portion 30C may be disposable replaceable parts.

In fig. 8 is a schematic representation of one example of the internal structure of the product 30 for inhaling the aroma of a substance. The main body 30A includes a power supply 31, a control unit 32, and an inhalant sensor 33. The control unit 32 is electrically connected to a power source 31 and a respirable matter sensor 33 . The power supply 31 is a secondary battery, etc. and supplies electrical energy to electrical circuits included in the aroma inhalation article 30. The control unit 32 is a processor, such as a microcontroller (microcontrol unit: MCU), that controls the operation of the electrical circuits present in the aroma inhalation product 30. The inhalant sensor 33 is, for example, an atmospheric pressure sensor, a flow meter, etc. When the user takes a puff from the mouthpiece of the aroma inhalation article 30, the inhalation sensor 33 detects the amount of negative pressure generated inside the aroma inhalation article 30, the gas flow rate, etc. Thus, the control unit 32 can determine the amount of inhaled substance based on the value detected by the inhaled substance sensor 33.

The aerosol source holding portion 30B in the aroma inhalation article 30 includes a storage unit 34, a supply unit 35, a load 36, and a residue sensor 37. The storage unit 34 is a container that contains a liquid aerosol source that is atomized when heated. The aerosol source is a polyol-based material such as glycerin or propylene glycol. The source of the aerosol can be a liquid mixture additionally containing liquid nicotine, water, flavoring and similar substances. It is assumed that such an aerosol source is placed in the storage unit 34 in advance. The aerosol source may be solid, in which case the storage unit 34 is not required.

The supply unit 35 includes a wick obtained by twisting fibers such as glass fiber. The supply unit 35 is connected to the storage unit 34. The supply unit 35 is connected to the load 36, or at least a portion of the supply unit 35 is located in the vicinity of the load 36. The aerosol source impregnates the wick by capillary forces and moves to a region in which the aerosol source can be atomized by heat using the load 36. In other words, in the supply unit 35, the aerosol source is moved from the storage unit 34 and transported to or near the load 36. The wick, instead of fiberglass, can be porous ceramics.

Load 36 is, for example, a coil heater that heats up when current flows through it. In addition, the load 36 has, for example, a positive temperature coefficient (PTC), and its resistance value is substantially directly proportional to the heating temperature achieved. The load 36 does not necessarily have to have a positive temperature coefficient; it is sufficient that there is a correlation between the value of its resistance and the heating temperature achieved. In one example, load 36 may have a negative temperature coefficient (NTC). The load 36 may be wound around the outer surface of the wick or, alternatively, may be designed such that the wick covers the peripheral portion of the load 36. The control unit 32 regulates the operation of the load 36 power source. When supplying an aerosol source from the storage unit 34 to the load 36 by supply unit 35, the aerosol source is evaporated by the heat generated by the load 36 to form an aerosol. If, based on the value detected by the inhaled substance sensor 33, it is detected that the user has inhaled, the control unit 32 applies voltage to the load 36 to produce an aerosol. If there is a sufficient amount of aerosol source remaining in the storage unit 34, then a sufficient amount of the aerosol source is supplied to the load 36, and the heat generated by the load 36 is transferred to the aerosol source. In other words, the heat generated by the load 36 is used to increase the temperature of the aerosol source and evaporate the aerosol source. Thus, in this case, the temperature of the load 36 almost never exceeds the preset temperature. On the other hand, if the aerosol source located in the storage unit 34 is depleted, then the amount of the aerosol source supplied to the load 36 per hour is reduced. As a result, the heat generated by the load 36 is not delivered to the aerosol source. In other words, the heat generated by the load 36 is not used to raise the temperature of the aerosol source and evaporate the aerosol source. Thus, in this case, the load 36 overheats, which in turn increases the resistance value of the load 36.

Residual sensor 37 provides data to estimate the amount of aerosol source remaining in storage unit 34 based on the temperature of load 36. For example, residual sensor 37 includes a current sensing resistor (shunt resistor) in series with load 36 and a meter in parallel. connected to a resistor and designed to measure the voltage across the resistor. The resistance value of the resistor is a predetermined constant value that essentially does not change with temperature. Thus, based on the known resistance value and the measured voltage value, the amount of current that flows through the resistor is obtained.

Contained within the additive-retaining portion 30C of the flavor inhalation article 30 is a tobacco filler 38. As described above, the tobacco filler 38 may include a “flavor-carrying component” according to the present invention, for example, “flavor-carrying cut tobacco”, “flavor-carrying component”. tobacco leaf material", "flavor-carrying tobacco granules", "flavor-carrying granular base material" or "flavor-carrying metal foil". In addition to the "flavor-carrying component", according to the present invention, the tobacco filler 38 may include a conventional tobacco filler. Conventional tobacco filler may consist of cut tobacco and/or cut pieces obtained by cutting tobacco sheet material into pieces of a certain width (cut tobacco sheet material). A ventilation hole is provided in the additional component holding portion 30C on the mouthpiece side and in the portion connected to the aerosol source holding portion 30B. Accordingly, when the user inhales through the mouthpiece, a negative pressure is created inside the additive holding part 30C, the user inhales the aerosol generated in the aerosol source holding part 30B, and components such as nicotine and aromatic components added to the aerosol inside the additive holding part 30B enter the user's oral cavity. component of part 30C.

Examples

1-1. Solubility of Flavor Retaining Agent in Liquid Composition Hydroxypropyl cellulose (Nippon Soda Co., Ltd.: CELNY SSL, the degree of substitution of which was approximately 3.5 per glucose residue) and one of the following solvents were mixed:

(a) water;

(b) ethanol;

(c) propylene glycol and

(d) a liquid mixture of propylene glycol and menthol.

Propylene glycol, which was selected as the liquid flavorant, has an octanol-water partition coefficient (log P) of -1.4 and is one example of a hydrophilic flavorant. Menthol, which was selected as a liquid flavor, has an octanol-water partition coefficient (log P) of 3.3 and is one example of a hydrophobic flavor.

Hydroxypropylcellulose was dissolved in each of solvents (a)-(d). The results obtained indicate that hydroxypropyl cellulose can be used both as a hydrophilic flavor retention agent and as a hydrophobic flavor retention agent.

1-2. Stability of a dispersion of particles containing an aromatic component in a liquid composition

A liquid suspension was prepared consisting of 1.25% wt. hydroxypropylcellulose (Nippon Soda Co., Ltd.: CELNY SSL, the degree of substitution of which was approximately 3.5 per glucose residue), 8.75 wt%. ethanol, 30.00% wt. glycerol, 40.00% wt. propylene glycol and 20.0% wt. crushed tobacco leaves (particle diameter: 70-250 µm) (Sample 1).

For a comparative sample, a liquid suspension consisting of 20.0 wt.% was prepared as a liquid suspension containing no hydroxypropylcellulose. crushed tobacco leaves (particle diameter: 70-250 microns), 30.0% wt. glycerol, 40.0% wt. propylene glycol and 10.0% wt. water (sample 2).

The viscosity of sample 1 (10 ml) and sample 2 (10 ml) at a temperature of 20°C was measured by an SV-10 device, from A&D Company, Limited. The results show that the viscosity of sample 1 was 1115±55 mPa⋅s, and the viscosity of sample 2 was 484±38 mPa⋅s.

93.0 g of each of samples 1 and 2 were placed in a glass screw-on tube and left for 48 hours. At this point, the distance from the bottom surface of the glass tube to the surface of the liquid suspension was approximately 75 mm.

Sample 1 showed no sedimentation of shredded tobacco leaves. In sample 2, the liquid layer was located at a distance of 5 mm from the surface of the liquid suspension, which confirmed the deposition of crushed tobacco leaves. It has been shown that hydroxypropylcellulose helps maintain the dispersed state of shredded tobacco leaves and can suppress the separation into a liquid layer and a solid layer.

2. State of flavor compositions on leaf tobacco material

2-1. State (1) of the flavor composition on the tobacco leaf material

In the example presented, a liquid flavor was used as a flavoring agent.

The prepared liquid A consisting of flavor (cinnamyl alcohol) was applied to the surface of the tobacco leaf material, and the tobacco leaf material was left at room temperature of 22° C. for 6 hours. In this manner, the flavor composition was applied to the tobacco leaf material.

In addition, prepared liquid B, consisting of hydroxypropyl cellulose (Nippon Soda Co., Ltd.: CELNY SSL, the degree of substitution of which was approximately 3.5 per glucose residue), ethanol and flavor (cinnamic alcohol), and the leaf was applied to the surface of the leaf. the tobacco material was left at room temperature of 22°C for 6 hours. In this manner, the flavor composition was applied to the tobacco leaf material.

results

In fig. Figure 9 shows the state of the front surface of the sheet and the rear surface of the sheet after 6 hours. In fig. 9 “A” indicates the effect of prepared liquid A, and “B” indicates the effect of prepared liquid B.

In the case of prepared liquid B, the flavoring agent did not reach (percolate) the back surface of the leaf, and a film (of the flavoring composition) was locally formed on the front surface of the leaf. It is believed that in the case of prepared liquid B, the ethanol sufficiently evaporated within 6 hours and a complex of flavor and hydroxypropyl cellulose was formed on the front surface of the sheet. On the other hand, in the case of prepared liquid A, percolation of the flavoring agent was confirmed to the rear surface of the tobacco leaf material.

In the detailed description of the present invention, it has been stated that hydroxypropylcellulose is expected to form a complex with a network structure when interacting with flavoring agent, and the results described above confirm the formation of a complex between hydroxypropylcellulose and flavoring agent.

2-2. State (2) of the flavor composition on the tobacco leaf material

In the presented example, particles containing a flavor (in particular, crushed tobacco leaves) were used as a flavoring agent.

1.900 g of a liquid suspension consisting of 3.70% ^wt . hydroxypropylcellulose (Nippon Soda Co., Ltd.: CELNY SSL, the degree of substitution of which was approximately 3.5 per glucose residue), 74.10 wt%. ethanol, 11.10% wt. glycerol and 11.10% wt. crushed tobacco leaves (particle diameter: 70-250 μm), and left at room temperature of 22°C for 18 hours. Ethanol was removed from the liquid suspension by evaporation. Thus, the flavor composition was applied to the tobacco leaf material. No liquid suspension was sprayed onto the back surface of the tobacco leaf material.

results

In fig. 10 shows the state of the front surface of the sheet and the back surface of the sheet after 18 hours. It was noted that there was a hard brown substance present on the front surface of the leaf, which is not typical of shredded tobacco leaves. No color change was observed on the back surface of the sheet compared to the back surface of the sheet before application of the liquid suspension. These results indicate that a fixed powder layer can be locally formed on the front surface of the tobacco sheet material (ie, a fixed powder layer is formed only on the front surface of the sheet and not on the rear surface of the sheet).

3. Change in the mass of tobacco leaf material containing flavoring caused by release of flavoring agent

1.900 g of a liquid mixture consisting of 3.7 wt.% was sprayed onto 0.800 g of leaf tobacco material. hydroxypropylcellulose (Nippon Soda Co., Ltd.: CELNY SSL, the degree of substitution of which was approximately 3.5 per glucose residue), 90.74 wt%. ethanol and 5.56% wt. glycerol, and left at room temperature of 22°C for 18 hours to evaporate the ethanol. Thus, a flavor-containing tobacco leaf material (Sample A) was prepared.

In addition, 1.900 g of a liquid mixture consisting of 94.44 wt.% was sprayed onto 0.800 g of leaf tobacco material. ethanol, and 5.56% wt. glycerol, and left at room temperature of 22°C for 18 hours to evaporate the ethanol. Thus, a flavor-containing tobacco leaf material (Sample B) was prepared.

Evaluation method

Samples A and B were cut into pieces of approximately 5 cm × 0.2 cm. From samples A and B, respectively, 0.2031 g and 0.2134 g of cut pieces were taken, and the dry matter loss of the samples was measured using a halogen moisture analyzer HR83-P from Mettler Toledo, with a heating temperature of 200°C and a heating duration of 900 seconds.

Dry matter mass loss (%) was determined according to the following formula:

Dry matter weight loss (%) = {(weight loss on drying) / (initial sample weight)} × 100

Since the dry matter loss of both samples A and B was essentially unchanged when the heating duration exceeded 900 seconds, the drying end period was set to 900 seconds.

Assuming that the dry matter mass loss after 900 seconds (end of drying) of heating is L900 (%), and the dry matter mass loss after t seconds of heating is Lt (%), the percentage R (%) of the residual components after evaporation at 200 ° C calculated according to the following formula:

R(%)={1 - (Lt / L900)} × 100

results

In fig. 11 shows the “percentage of residual components after evaporation at 200°C.” In fig. 11, the horizontal axis shows the heating duration (seconds), and the vertical axis shows the percentage of residual components after evaporation at 200°C.

The results presented in Fig. 11 show that at the initial stage of heating (the period from the start of drying to 200 seconds of drying duration), the percentage of residual components after evaporation at 200 ° C decreases to a greater extent in sample A than in sample B. This indicates that in In sample A, at the initial stage of heating, a larger amount of glycerol evaporates than in sample B. When heating the tobacco sheet material, its surface temperature first increases, after which its internal temperature gradually increases. Thus, the evaporation of more glycerol during the initial heating stage in sample A than in sample B indicates that glycerin is locally present on the surface of the tobacco sheet material without penetrating into the tobacco sheet material. This indicates that hydroxypropyl cellulose forms a complex with glycerol, and the complex is locally present only on the surface of the tobacco leaf material.

In the detailed description of the present invention, it has been stated that hydroxypropyl cellulose is expected to form a network complex when interacting with flavor, and the results described above confirm the formation of a complex between hydroxypropyl cellulose and flavor.

4. Preparation of flavor-bearing tobacco sheet material and flavor inhalation product
