セルロース系基材とニコチンとを混合する方法は、特に限定されないが、ニコチンをセルロース系基材の外部から供給することにより混合することが好ましい。ニコチンをセルロース系基材の外部から供給することにより、ニコチンの少なくとも一部がセルロース系基材表面に存在するようになる。これにより、セルロース系基材の内部にニコチンが存在する場合より、ニコチンが香味吸引物品用材料の外部へ放出されやすくなり、その結果、従来の200℃以上などの温度より低い加熱温度でもニコチンが十分に放出されることとなる。ここで、セルロース系基材は、その表面が多数の孔を有する(多孔質の形状を有する)こともあり、この場合、セルロース系基材の表面には、当該孔の内部の部分も含まれる。 1. Flavor Inhalation Article Material In some embodiments of the present application, the flavor inhalation article material comprises a mixture of a cellulosic-based substrate and nicotine.
The method of mixing the cellulosic base material and nicotine is not particularly limited, but it is preferable to mix by supplying nicotine from the outside of the cellulosic base material. By supplying nicotine externally to the cellulosic substrate, at least a portion of the nicotine is present on the surface of the cellulosic substrate. As a result, nicotine is more likely to be released to the outside of the material for flavor inhalation articles than when nicotine is present inside the cellulosic base material. enough to be released. Here, the cellulose-based substrate may have a large number of pores on its surface (has a porous shape), and in this case, the surface of the cellulose-based substrate includes the inner portion of the pores. .
本明細書において、「たばこ葉」とは、収穫されたたばこの葉が、後述する熟成を経る前のものの総称である。なお、熟成の一態様にはキュアリングが含まれる。
これに対して、熟成を経たたばこ葉であって、たばこ製品で利用される種々の形態(後述するたばこ刻や、たばこシート、たばこ顆粒等)に加工される前のものを「熟成済たばこ葉」と称する。さらに、熟成済たばこ葉を、たばこ製品で利用される種々の形態に加工したものを「加工済たばこ葉」と称する。 <Tobacco leaves, aged tobacco leaves, and processed tobacco leaves>
As used herein, the term "tobacco leaf" is a general term for harvested tobacco leaves before ripening, which will be described later. One mode of aging includes curing.
On the other hand, aged tobacco leaves before being processed into various forms used in tobacco products (such as cut tobacco, tobacco sheets, tobacco granules, etc.) are referred to as "aged tobacco leaves." ”. Furthermore, the aged tobacco leaves processed into various forms used in tobacco products are referred to as "processed tobacco leaves".
たばこ充填物は、加工済たばこ葉が被充填物に所定の態様で充填されたものを指す。「被充填物」とは、加工済たばこ葉が充填される対象であり、たばこ製品の一部である。被充填物としては、巻紙を筒状にしたものや、空気の流入口と流出口とを備える収容体などを挙げることができるが、これらに限定されない。
加工済たばこ葉が、被充填物に充填される態様としては、加工済たばこ葉が内側となるように巻紙で巻装されることで充填される態様(以下、「たばこロッド」ともいう。)や、加工済たばこ葉が空気の流入口と流出口とを備える収容体の流路に充填される態様(以下、「たばこカートリッジ」ともいう。)等を挙げることができるが、これらに限定されることはない。 <Tobacco filling>
Tobacco filling refers to a material filled with processed tobacco leaves in a predetermined manner. "Filled material" is the object into which the processed tobacco leaves are filled and is a part of the tobacco product. Examples of the stuff to be filled include, but are not limited to, a roll of paper rolled into a cylinder, a container having an air inlet and an air outlet, and the like.
As a mode in which the processed tobacco leaves are filled into the filling material, the processed tobacco leaves are wrapped in wrapping paper so that the processed tobacco leaves are on the inside (hereinafter also referred to as "tobacco rod"). and a mode in which processed tobacco leaves are filled into a flow path of a container having an air inlet and an air outlet (hereinafter also referred to as a "tobacco cartridge"), etc., but are not limited to these. never
上述のとおり、たばこ顆粒は、熟成済たばこ葉を含む組成物を、顆粒形状に成形して得られるものである。 <Tobacco granules>
As described above, tobacco granules are obtained by molding a composition containing aged tobacco leaves into granules.
たばこ顆粒を成形する方法は、特に限定されないが、例えば、たばこ細粉、ニコチン、香味発現助剤およびバインダー並びに所望によりエアロゾル生成基材、香料を混合し、その混合物に水を加えて混練し、得られた混練物を湿式押出し造粒機で造粒(長柱状)した後、短柱状あるいは球状に整粒することにより得ることができる。たばこ顆粒は、たばこ由来の原料からのニコチンと、添加されたニコチンの双方を含む。
押出し造粒に際しては、混練物を周囲温度で、2kN以上の圧力で押出すことが好ましい。この高圧での押出しにより、押出し造粒機出口での混練物は温度が周囲温度から例えば90℃~100℃まで瞬間的に急激に上昇し、水分および揮発性成分が2~4重量%蒸発する。したがって、混練物を作るために配合する水は、最終製品であるたばこ顆粒中の所望水分よりも上記蒸発量だけ多くの量で用いることができる。
押出し造粒により得られたたばこ顆粒は、水分調整のために、必要に応じてさらに乾燥させてもよい。たとえば、押出し造粒により得られたたばこ顆粒の乾燥減量を測定し、それが、所望の乾燥減量(たとえば5重量%以上、17重量%以下)より高い場合、所望の乾燥減量を得るためにたばこ顆粒をさらに乾燥させてもよい。所望の乾燥減量を得るための乾燥条件(温度および時間)は、乾燥減量を所定の値だけ減少させるために必要な乾燥条件(温度および時間)を予め決定し、その条件に基づいて設定することができる。 <Tobacco Granule Forming Method>
The method of forming tobacco granules is not particularly limited, but for example, tobacco powder, nicotine, a flavor development aid, a binder, and optionally an aerosol-generating base material and a flavoring agent are mixed, water is added to the mixture, and the mixture is kneaded. The obtained kneaded product is granulated (long columnar) with a wet extrusion granulator, and then granulated into a short columnar or spherical shape. Tobacco granules contain both nicotine from the tobacco-derived material and added nicotine.
During extrusion granulation, it is preferred to extrude the kneaded material at ambient temperature and at a pressure of 2 kN or more. Due to this high-pressure extrusion, the temperature of the kneaded material at the outlet of the extrusion granulator instantaneously rises sharply from the ambient temperature to, for example, 90° C. to 100° C., and 2 to 4% by weight of water and volatile components evaporate. . Therefore, the amount of water to be blended for making the kneaded product can be used in an amount larger than the desired water content in the final tobacco granules by the amount of evaporation described above.
Tobacco granules obtained by extrusion granulation may be further dried for moisture adjustment, if necessary. For example, the loss on drying of tobacco granules obtained by extrusion granulation is measured, and if it is higher than the desired loss on drying (for example, 5% by weight or more and 17% by weight or less), tobacco is added to obtain the desired loss on drying. Granules may be further dried. The drying conditions (temperature and time) for obtaining the desired loss on drying should be determined in advance and set based on the drying conditions (temperature and time) required to reduce the loss on drying by a predetermined value. can be done.
上述のとおり、たばこシートは、熟成済たばこ葉などを含む組成物を、シート形状に成形して得られるものである。たばこシートに使用される熟成済たばこ葉は、特に限定されないが、例えば、除骨され、ラミナと中骨に分離されたものを挙げることができる。また、本明細書において「シート」とは、略平行な1対の主面、及び側面を有する形状をいう。 <Tobacco sheet>
As described above, the tobacco sheet is obtained by forming a composition containing aged tobacco leaves and the like into a sheet shape. The aged tobacco leaf used for the tobacco sheet is not particularly limited, but examples thereof include those that have been deboned and separated into lamina and backbone. In this specification, the term "sheet" refers to a shape having a pair of substantially parallel main surfaces and side surfaces.
たばこシートの成形方法は、特に限定されないが、例えば、たばこ細粉、ニコチン、香味発現助剤およびバインダー並びに所望によりエアロゾル生成基材、香料を混合し、その混合物に水を加えて混練し、得られた混練物を抄造法、キャスト法、圧延法、等の公知の方法で成形することができる。このような方法で成形された各種たばこシートについては、「たばこの事典、たばこ総合研究センター、2009.3.31」に詳細が開示されている。 <Tobacco sheet molding method>
The method of forming the tobacco sheet is not particularly limited. The resulting kneaded product can be molded by a known method such as a papermaking method, a casting method, a rolling method, or the like. Various tobacco sheets formed by such a method are disclosed in detail in "Encyclopedia of Tobacco, Tobacco Research Center, March 31, 2009".
当該顆粒の粒径及び平均粒径(D50)は、散乱式粒子径分布測定装置(Partica、ヤマト科学株式会社製)を使用して乾式の条件下でレーザー回析法に基づいて測定することができる。 When the material for flavor inhalation articles is in the form of granules, the particle size of the granules is not particularly limited, but from the viewpoint of improving the release efficiency of nicotine and/or menthol, which will be described later, it is preferably 250 μm or more, and 250 to 850 μm.

Burley tobacco cuts with a nicotine concentration of 0.01%, heated at 120° C. and washed four times with water, were pulverized in a mill and sieved through a sieve with an opening of 50 μm to obtain fine tobacco powder having a size of less than 50 μm. Obtained. Tobacco powder thus obtained: 1000 g, CMC (carboxymethyl cellulose): 50 g and glycerin: 100 g were mixed, and 300 g of water was added to the resulting mixture and kneaded. The resulting kneaded product is put into a wet extrusion granulator (TDG-80A-1, manufactured by Dalton Co., Ltd.) and granulated into long columns under the conditions of pressure: 250 kN and temperature: 80 ° C., and then spherically. After sizing, tobacco granules (spherical) (particle size: 250-500 μm, average particle size (D50): 352 μm) were obtained.
Tobacco granules (spherical) (particle size: 500 to 850 µm, average particle size (D50): 643 µm) were prepared in the same manner as described above, except that the granulation conditions of the wet extrusion granulator were changed to pressure: 200 kN and temperature: 75°C. ).
The particle size of the above granules was dried at 100° C. for 2 hours, and then measured by laser diffraction under dry conditions using a scattering particle size distribution analyzer (Partica, manufactured by Yamato Scientific Co., Ltd.). .
空の無底円筒体(材質:紙、内径約6.8mm)に、上述のようにして得られたたばこ顆粒A又はBを100mg、200mg、又は300mg充填した後、当該円筒体の両端にアセテートフィルター(日本フィルター工業株式会社製)を配置して当該たばこ顆粒を密封した。円筒体に配置した片方のアセテートフィルターに隣接して、円筒体側から、ガラス繊維フィルター(商品名:CambridgeFilter44mm、Borgwaldt社製)及び喫煙器(一本掛け喫煙器、Borgwaldt社製)を順に配置した。たばこ顆粒を収容した円筒体を外部からヒーター(設定温度:55℃又は70℃)により加熱して蒸気及びエアロゾルを発生させ、発生した蒸気及びエアロゾルを喫煙器により吸引した。吸引は、CIR法(カナダ強制喫煙条件法)に基づき、1パフ当たり55ml/2秒とし(1パフは30秒間隔、すなわち2秒間吸引して28秒間待機すること)、計10パフ行った。そして、10パフ後にガラス繊維フィルターにより捕集されたニコチン及びメンソールの量を定量することにより、10パフ当たりのニコチン又はメンソールの捕集量(吸入量)の値を得た。当該定量は、捕集された成分をイソプロパノール(IPA) 10mlを抽出溶媒とし、20分間、200rpmの条件で振とう抽出し、得られた抽出液を以下の条件でGC分析することにより行った。 (Analysis of nicotine and menthol released from tobacco granules)
After 100 mg, 200 mg, or 300 mg of tobacco granules A or B obtained as described above were filled in an empty bottomless cylinder (material: paper, inner diameter of about 6.8 mm), acetate was placed on both ends of the cylinder. A filter (manufactured by Japan Filter Industry Co., Ltd.) was arranged to seal the tobacco granules. A glass fiber filter (trade name: Cambridge Filter 44 mm, manufactured by Borgwald) and a smoking device (one-piece smoking device, manufactured by Borgwald) were placed in this order from the cylindrical body side adjacent to one acetate filter placed in the cylindrical body. A cylindrical body containing tobacco granules was externally heated by a heater (set temperature: 55° C. or 70° C.) to generate steam and aerosol, and the generated steam and aerosol were inhaled with a smoking device. Based on the CIR method (Canadian Compulsory Smoking Condition Law), 1 puff was 55 ml/2 seconds (1 puff is an interval of 30 seconds, i.e., suction for 2 seconds and waiting for 28 seconds), and a total of 10 puffs were performed. After 10 puffs, the amount of nicotine and menthol collected by the glass fiber filter was quantified to obtain the amount of nicotine or menthol collected (inhaled amount) per 10 puffs. The quantification was carried out by extracting the collected components with 10 ml of isopropanol (IPA) as an extraction solvent with shaking at 200 rpm for 20 minutes, and subjecting the resulting extract to GC analysis under the following conditions.
注入口温度:240℃
オーブン温度:150℃で1.3分間保持後、70℃/minで240℃まで昇温し、5分間保持
カラム:商品名:DB-WAX 10m×0.18mm×0.18μm、Agilent社製
検出器:FID <GC analysis conditions>
Inlet temperature: 240°C
Oven temperature: Hold at 150°C for 1.3 minutes, then heat up to 240°C at 70°C/min and hold for 5 minutes Column: Trade name: DB-WAX 10m × 0.18mm × 0.18μm, manufactured by Agilent Detection Instrument: FID
さらに、ニコチン及びメンソールのそれぞれについて、ニコチン又はメンソールの充填量に対する10パフ当たりの捕集量の割合(10パフ当たりの捕集量/充填量 ×100)(以下「10回吸引当たりのリリース効率」という)を算出した。
得られた結果を表1並びに図3及び4に示す。 In addition, the weight of the glass fiber filter before smoking is subtracted from the weight of the glass fiber filter after smoking to calculate the difference in weight of the glass fiber filter before and after smoking, and the weight difference is transferred to the vapor and aerosol inhaled by the smoking device. It is the amount of total particulate matter (TPM) contained.
Furthermore, for each of nicotine and menthol, the ratio of the amount captured per 10 puffs to the filling amount of nicotine or menthol (capture amount per 10 puffs/filling amount × 100) (hereinafter "release efficiency per 10 suctions" ) was calculated.
The results obtained are shown in Table 1 and FIGS.
表1並びに図3及び4の結果より、実施例1~12の香味吸引物品用材料は、加熱温度を70℃という、従来の200℃以上に比べて低い温度にしても、10回吸引当たりのニコチンのリリース効率が1.8%以上となり、ニコチンを放出しやすいことがわかった。加えて、実施例1~12の香味吸引物品用材料は、加熱温度を70℃という低い温度にしても、10回吸引当たりのメンソールのリリース効率が7%以上となり、メンソールを放出しやすいことがわかった。 The materials for flavor inhaling articles of Examples 1 to 12 are materials for flavor inhaling articles obtained by mixing a cellulosic base material and nicotine.
From the results in Table 1 and FIGS. 3 and 4, the materials for flavor inhalation articles of Examples 1 to 12 were heated to 70° C., which is lower than the conventional heating temperature of 200° C. or higher. The nicotine release efficiency was 1.8% or higher, indicating that nicotine is easily released. In addition, the materials for flavor inhalation articles of Examples 1 to 12 have a menthol release efficiency of 7% or more per 10 inhalations even when the heating temperature is as low as 70°C, indicating that menthol is easily released. have understood.
さらに、ニコチンの充填量が低くなればなる程、10回吸引当たりのニコチンのリリース効率が高くなる傾向があることがわかった。この点について、たばこ顆粒の粒径が同じ場合、ニコチンの充填量が低くなるにつれて、たばこ顆粒の表面に付着するニコチンの層が薄くなると考えられる。ニコチンの層が厚いと当該層の下方にあるニコチンがリリースされにくいと考えられる。一方、ニコチンの層が薄いと当該層全体からニコチンがリリースされやすくなり、このため、ニコチンのリリース効率が高くなると考えられる。
ニコチンに関して見られるこれらの傾向は、メンソールのリリース効率にも同様にして見られた。これらのメンソールのリリース効率の傾向もメンソールと同様の原因により発生していると思われる。 Further, from the results in Table 1 and FIGS. 3 and 4, even at the same heating temperature, tobacco granules A, which have a smaller particle size, have a higher nicotine release efficiency per 10 inhalations than tobacco granules B, which have a larger particle size. It was found that there is a tendency In this regard, it is considered that the total surface area of all the tobacco granules increases as the particle size of the tobacco granules decreases when the tobacco granules have the same filling amount. Such an increase in surface area is thought to increase the amount of nicotine present on the surface of the tobacco granules to be released, thereby increasing the nicotine release efficiency.
Furthermore, it was found that the lower the nicotine loading, the higher the nicotine release efficiency per 10 puffs. In this regard, when the particle size of the tobacco granules is the same, the lower the nicotine filling amount, the thinner the nicotine layer adhering to the surface of the tobacco granules. It is believed that if the nicotine layer is thick, the nicotine below the layer is less likely to be released. On the other hand, if the nicotine layer is thin, the nicotine is more likely to be released from the entire layer, which is thought to increase the nicotine release efficiency.
These trends seen for nicotine were similarly seen for menthol release efficiency. It is believed that these trends in release efficiency of menthol are caused by the same cause as menthol.
