Description

Flavor molded body and method for producing the same, method for producing tobacco materials, and method for producing tobacco products

The present invention relates to flavor molded bodies and methods for producing the same, methods for producing tobacco materials, and methods for producing tobacco products.

As a method of uniformly imparting flavor to tobacco products, for example, Patent Document 1 discloses a flavor addition method in which leaf tobacco particles are suspended in a dispersion medium and then added to raw leaf tobacco by spray or the like.

Additionally, as one of the tobacco products, for example, patent documents 2 and 3 disclose tablet oral tobacco. In molding oral tobacco tablets, molding is generally performed using a binder.

On the other hand, in Patent Document 4, tobacco pieces with a cutting width of 0.6 to 1 mm are aged under airtight conditions in an air atmosphere, and polyol is added to the aged tobacco pieces, thereby producing enhanced ester aroma components and flavor. It is disclosed that it is possible to manufacture a tobacco material in which the composition of ingredients contributing to the taste is difficult to change over time.

Patent Document 1: International Publication No. 2014/185103 Patent Document 2: Japanese Patent Publication No. 2017-79764 Patent Document 3: Japanese Patent Publication No. 2012-85643 Patent Document 4: International Publication No. 2013/098920

However, as in the flavor addition method disclosed in Patent Document 1, when fine powder tobacco raw materials are used as flavor raw materials, dust may scatter during storage or transportation of the powder raw materials, or loss of the powder raw materials may occur. This may occur, or the flavor components may volatilize from the powdered raw materials. Therefore, there is a need for the development of flavor molded products that are easy to store and transport, and which suppress volatilization of flavor components during storage and transport.

Additionally, while the binder used in the molding of oral tobacco tablets improves the moldability (strength) of the tablet, it sometimes reduces the flavor. Therefore, there is a demand for the development of flavor molded products that have sufficient strength and good flavor.

The purpose of the present invention is to provide a flavor molded body that is easy to store and transport, suppresses volatilization of flavor components during storage and transport, has sufficient strength, and has a good flavor, and tobacco materials and tobacco products using the flavor molded object.

[Method for manufacturing flavor molded body]

The manufacturing method of the flavor molded body according to this embodiment includes the following steps. A process of forming a mixture by mixing alcohol having 2 to 7 carbon atoms with a tobacco powder raw material with an average particle diameter of 100 μm or less (hereinafter also referred to as “alcohol mixing process”); A process of compression molding the mixture (hereinafter also referred to as “compression molding process”); A process of removing at least a portion of the alcohol from the mixture (hereinafter also referred to as “alcohol removal process”).

In the method according to the present embodiment, alcohol having 2 to 7 carbon atoms is mixed with a tobacco powder raw material with an average particle diameter of 100 μm or less and compression molded, so that a flavor molded body with sufficient strength can be obtained. As described later, by adding alcohol having 2 to 7 carbon atoms to the tobacco powder raw material, the resin composition derived from the tobacco powder raw material transfers to the surface of the tobacco powder raw material, and the tobacco powder raw materials are bonded to each other through the resin composition, thereby providing sufficient It is assumed that a strong flavor molded body can be obtained. Additionally, it is presumed that a flavor molded body with sufficient strength can be obtained by dehydrating some of the hydroxyl groups of the cellulose contained in the tobacco powder raw material and condensing it with nearby cellulose. By using the flavor molded body manufactured by the method according to the present embodiment as a flavor raw material in the above flavor addition method, storage and transportation are easy, and volatilization of flavor components during storage and transportation is suppressed. Additionally, since the flavor molded body according to the present embodiment easily disintegrates in a dispersion medium, a suspension of tobacco powder raw materials can be easily prepared.

In addition, since compression molding is performed using alcohol having 2 to 7 carbon atoms in the method according to the present embodiment, there is no need to use a general binder during molding, and since most of the alcohol used is removed, sufficient strength is maintained. Additionally, a flavor molded body with good flavor can be obtained. Therefore, the flavor molded body manufactured by the method according to the present embodiment is suitable as an oral cigarette.

The tobacco powder raw material with an average particle diameter of 100 μm or less used in the method according to the present embodiment can be a fine fraction of leaf tobacco generated when regrinding leaf tobacco in the production of tobacco products. Normally, when tobacco products such as cigarettes are manufactured in a tobacco manufacturing factory, leaf tobacco is subdivided in the process of reprocessing the leaf tobacco. Most of the above-described subdivisions are returned to the rebuilding plant and rebuilt into sheets in the papermaking sheet process. According to the method according to the present embodiment, a flavor molded body can be manufactured using the above fine powder. The flavor molded body can be returned to the rebuilding plant and used as a starting material for the papermaking sheet process. Alternatively, it can be reused by adding it to the raw material mixing process in the production of tobacco granule raw materials. In this way, by subdividing leaf tobacco into flavor molded products, storage and transportation are facilitated, and volatilization of flavor components during storage and transportation is suppressed. In addition, since the method according to the present embodiment does not use a general binder during molding, the flavor molded body produced by the method does not generate flavors other than those derived from tobacco and is easy to use in the reuse process.

Hereinafter, each process in the method according to the present embodiment will be described. However, the method according to the present embodiment may include processes other than the alcohol mixing process, compression molding process, and alcohol removal process. Additionally, the alcohol removal process may be performed during the compression molding process, as long as it follows the alcohol mixing process, or may be performed after the compression molding process.

(Alcohol mixing process)

In this process, a tobacco powder raw material with an average particle diameter of 100 μm or less is mixed with alcohol having 2 to 7 carbon atoms to form a mixture. Tobacco powder raw materials include leaf tobacco, veins, stems, roots, and flowers. As the leaf tobacco, for example, as described above, fine fractions of leaf tobacco generated when leaf tobacco is reprocessed in the production of tobacco products can be used. The type of leaf tobacco is not particularly limited, and may include yellow species, Burley species, native species, orient leaves, etc., or their fermented leaves. These tobacco powder raw materials may be used one type, or two or more types may be used together.

The average particle diameter of the tobacco powder raw material is 100 μm or less. When the average particle diameter is 100 μm or less, it is possible to obtain a flavor molded body that is free from deformation over time and has sufficient strength. The average particle diameter is preferably 5 to 80 μm, more preferably 10 to 60 μm, and still more preferably 20 to 50 μm. Additionally, the average particle diameter is measured using a light scattering method.

The carbon number of the alcohol is 2 to 7, preferably 2 to 5, and more preferably 2 to 3. As the alcohol, at least one alcohol selected from the group consisting of ethanol, 2-propanol, and benzyl alcohol is preferable from the viewpoint of obtaining a flavor molded product with higher strength, and ethanol is most preferable.

In this process, it is preferable to mix 1 to 20 parts by mass of the alcohol with respect to 100 parts by mass of the tobacco powder raw material. By mixing 1 part by mass or more of the alcohol with 100 parts by mass of the tobacco powder raw material, a flavor molded body with higher strength can be obtained. In addition, compression molding can be easily performed by mixing 20 parts by mass or less of the alcohol with respect to 100 parts by mass of the tobacco powder raw material. In this process, it is more preferable to mix 3 to 17 parts by mass of the alcohol, and more preferably 5 to 15 parts by mass, with respect to 100 parts by mass of the tobacco powder raw material.

In this process, in addition to the alcohol, for example, cellulose powder or the like may be further added to the tobacco powder raw material. By mixing cellulose powder, the strength of the flavor molded body is further improved.

The method of mixing the alcohol with the tobacco powder raw material is not particularly limited, but mixing can be done using, for example, a general mixer such as a V-type mixer.

(Compression molding process)

In this process, the mixture obtained in the alcohol mixing process is compression molded. The compression molding machine used for compression molding is not particularly limited, but for example, a rotary tablet press can be used. The conditions for compression molding are not particularly limited, but for example, it is preferable to mold with a compression pressure of 2 kN or more. Additionally, as described above, for example, at least part of the alcohol may be removed by natural drying or the like during compression molding.

The shape of the molded body obtained by compression molding is not particularly limited, but may be, for example, tablet-shaped, plate-shaped, cylindrical, rod-shaped, or spherical.

(Alcohol removal process)

In this process, at least a portion of the alcohol is removed from the mixture. Here, as described above, removal of at least part of the alcohol may be performed on the mixture during the compression molding process, or may be performed on the molded body obtained after the compression molding process.

In this process, it is preferable to remove at least part of the alcohol at 10 to 40°C. By removing at least part of the alcohol at 10°C or higher, the alcohol can be sufficiently removed. Additionally, by removing at least part of the alcohol below 40°C, the effect of heating on flavor can be suppressed. The temperature for removing at least part of the alcohol is more preferably 15 to 35°C, and more preferably 20 to 30°C. When removing at least part of the alcohol at 10 to 40°C, for example, at least part of the alcohol can be removed by drying at 10 to 40°C for 30 to 120 minutes. Removal of at least part of the alcohol can be performed, for example, by electric oven, hot air drying, tunnel dryer, natural drying, etc. In addition, the removal of the alcohol is preferably performed in an open space, not in a closed space.

By this process, it is preferable that 90% by mass or more of the alcohol contained in the mixture (molded article) is removed, more preferably 95% by mass or more is removed, and even more preferably 99% by mass or more is removed, It is particularly preferred that all alcohol is removed.

[Flavor Molded Body]

The flavor molded body according to this embodiment is manufactured by the manufacturing method of the flavor molded body according to this embodiment. The flavor molded body is easy to store and transport, volatilization of flavor components is suppressed during storage and transport, has sufficient strength, and has a good flavor.

The compressive breaking strength of the flavor molded body by a wedge-shaped plunger, measured using a tablet hardness meter, is preferably 10 to 200 N. When the compressive breaking strength is 10 N or more, the shape can be maintained without easily collapsing, making storage and transportation easy. In addition, when the compressive breaking strength is 200 N or less, the flavor molded body collapses more easily in the dispersion medium, and a suspension of the tobacco powder raw material can be easily prepared. Additionally, the range of compressive breaking strength described above is also suitable for use as an oral cigarette. The compressive breaking strength is more preferably 20 to 150 N. In addition, the compressive breaking strength is a value measured specifically by a method described later.

The shape of the flavor molded body according to the present embodiment is not particularly limited, but may be, for example, tablet-shaped, plate-shaped, cylindrical-shaped, rod-shaped, spherical, etc.

The flavor molded body according to the present embodiment may be a flavor molded body formed by bonding a plurality of tobacco powder raw materials with an average particle diameter of 100 μm or less to each other through a resin composition derived from the tobacco powder raw material. By mixing the alcohol, the resin composition is extracted from the inside of the particles of the tobacco powder raw material, transfers to the surface of the particles, and the particles adhere to each other by the resin contained in the resin composition, so that sufficient strength can be obtained. It is assumed that there is. Additionally, since the resin derived from the tobacco powder raw material functions as a binder, the flavor molded body does not need to contain a general binder and has a good flavor. It can be confirmed by Raman imaging or the like that a plurality of tobacco powder raw materials are bonded to each other through a resin composition derived from the tobacco powder raw material.

The resin composition derived from the tobacco powder raw material may include resins such as soranesol, neophytadiene, and megastigmatrienone. The resin composition may contain one type of the resin, or may contain two or more types of the resin. In addition, the resin composition derived from the tobacco powder raw material may contain flavor components contained in the tobacco powder raw material, such as nicotine.

In addition, the flavor molded body according to the present embodiment is a flavor molded body containing a tobacco powder raw material with an average particle diameter of 100 μm or less and a cellulose content of 5 to 15% by mass, wherein at least a portion of the cellulose is dehydrated and condensed. It may be a flavor molded body. It is presumed that a flavor molded body with sufficient strength can be obtained by dehydrating some of the hydroxyl groups of the cellulose contained in the tobacco powder raw material and condensing it with nearby cellulose. In addition, when the cellulose content of the tobacco powder raw material is 5 to 15 mass%, it is possible to achieve a compressive breaking strength range (10 to 200 N) suitable for the flavor molded article according to this embodiment. The cellulose content of the tobacco powder raw material can be measured by the TAPPI method or the like. In addition, dehydration condensation of at least part of the cellulose can be confirmed by NMR spectrum analysis or the like.

For example, as described later, the flavor molded body according to the present embodiment is prepared by adding the flavor molded body to a dispersion medium, producing a tobacco material in which the tobacco powder raw material is dispersed in the dispersion medium, and applying the tobacco material to a tobacco product. By adding it, it can be used in a method of imparting flavor to tobacco products. Additionally, the flavor molded body according to this embodiment is suitable as an oral cigarette. Additionally, as the tobacco powder raw material contained in the flavor molded body according to the present embodiment, fine fractions of leaf tobacco generated when leaf tobacco is reheated in the production of tobacco products can be used.

According to the manufacturing method of the tobacco material according to this embodiment, the tobacco material used when imparting flavor to a tobacco product can be manufactured simply and efficiently. In particular, since the flavor molded body according to the present embodiment is used instead of using a fine powder tobacco raw material as the tobacco raw material, storage and transportation of the tobacco raw material are easy, and volatilization of the flavor component during storage or transportation is suppressed. Additionally, since the flavor molded body according to the present embodiment easily disintegrates in a dispersion medium, a dispersion of tobacco powder raw materials can be easily prepared.

Examples of the dispersion medium for adding the flavor molded product include water, monohydric alcohol, polyhydric alcohol, sugar alcohol, saccharides, and polyhydric alcohol ester. Examples of monohydric alcohols include methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 2,2-dimethyl ethanol, cyclohexanol, etc. Examples include monohydric aliphatic alcohols, monohydric alcohols with an aromatic substituent such as benzyl alcohol, monohydric alcohols containing one or more halogen elements, and monohydric alcohols with one or more ether bonds. Examples of polyhydric alcohols include glycerin, propylene glycol, and the like. Examples of sugar alcohols include sorbitol, maltitol, xylitol, erythritol, lactitol, sorbitan, xylose, arabinose, mannose, and trehalose. Examples of saccharides include lactose, sucrose, coupling sugar, glucose, enzyme starch syrup, acid saccharified starch syrup, maltose starch syrup, maltose, isomerized sugar, fructose, reduced maltose, reduced starch syrup, and honey. Examples of polyhydric alcohol esters include fatty acid polyhydric alcohol esters such as fatty acid triglycerides. Among these, the dispersion medium is preferably water or a combination of water and something soluble in water.

The amount of the flavor molded body added to the dispersion medium is not particularly limited, but may be, for example, 5 to 100 parts by mass per 100 parts by mass of the dispersion medium. The tobacco material manufactured by the method according to the present embodiment may be in a slurry form in which the tobacco powder raw material of the flavor molded body is dispersed in a dispersion medium.

In particular, since the tobacco material is manufactured by the tobacco material manufacturing method according to the present embodiment, the effects based on the tobacco material manufacturing method according to the present embodiment described above can be obtained.

Tobacco products to which tobacco ingredients are added are not particularly limited, and examples include leaf tobacco, dried leaf tobacco, flavored leaf tobacco, shredded tobacco, cigarettes, cigar tobacco, pipes, hookah, hookah, oral tobacco, and snuff. The method of adding the tobacco material is not particularly limited, but it is preferable to spray the tobacco material onto the tobacco product using a spray because the flavor components contained in the tobacco material can be more uniformly applied to the tobacco product.

Example

Specifically, a wedge-shaped plunger (product name: TH-1, manufactured by Az One Co., Ltd.) is slowly lowered against the compression molded body, and the strength when the compression molded body is compressed and fractured is measured using a tablet hardness tester (brand name: TH-1, manufactured by Az One Corporation). ) was measured three times. The average value of the values measured three times was taken as the compressive breaking strength (N).

[Flavor evaluation]

A suspended slurry was prepared by adding 6 times the amount of water to the mass of the produced compression molded body. 2.8 g of the slurry was added to 20 g of a commercially available tobacco product (shredded tobacco) by spraying to impart flavor to the tobacco product. After that, the tobacco product was conditioned for 24 hours under conditions of 22°C and 60% relative humidity. Cigarettes were produced using the blended tobacco products, and sensory evaluation of flavor was performed. Additionally, sensory evaluation was conducted by sufficiently trained panelists. In addition, when cigarettes were manufactured in the same manner as slurry using tobacco powder raw materials instead of compressed molded products, and sensory evaluation was performed (Reference), sugar odor and orange flavor increased.
