Description

喫煙物品配合用たばこ刻の製造方法Method for producing cigarettes for smoking articles
 本発明は、喫煙物品配合用たばこ刻の製造方法に関する。 The present invention relates to a method for producing a cigarette for smoking article blending.
 シガレット等の喫煙物品の喫煙に際して、喫煙物品からは、喫煙物品本体を通じて喫煙者により吸引される主流煙、および特に自然燃焼時に喫煙物品の先端部から立ち昇る副流煙が発生する。当該技術分野において、副流煙を低減する種々の技術が報告されており、例えば、特許文献1は、二重巻紙を用いたシガレットを報告する。 When smoking a cigarette or other smoking article, the smoking article generates mainstream smoke sucked by the smoker through the smoking article main body and particularly sidestream smoke rising from the tip of the smoking article during natural combustion. In the technical field, various techniques for reducing sidestream smoke have been reported. For example, Patent Document 1 reports a cigarette using a double wrapping paper.
国際公開第99/35923号International Publication No. 99/35923
 特許文献1では、巻紙が二重でかつ内側の巻紙が難通気性であるため、シガレットの燃焼時に、巻紙の内部に熱がこもり易く、外部へ放出されにくく、これにより燃焼部の温度が上昇し易い。その結果、特許文献1のシガレットは、通常の巻紙を有するシガレットと比べて、燃焼速度が増加し、シガレットの喫煙回数(すなわち、所定の吸い殻の長さになるまで吸煙するのに要する回数)が減る傾向がある。シガレットの喫煙は、喫煙者をリラックスさせ、ゆとりある時間を提供することができる。そのため、喫煙回数は、喫煙者にとって重要なシガレット性能の一つである。 In Patent Document 1, since the wrapping paper is double and the inner wrapping paper is hard to breathe, when the cigarette is burned, heat easily accumulates inside the wrapping paper and is not easily released to the outside, thereby increasing the temperature of the combustion section. Easy to do. As a result, the cigarette of Patent Document 1 has a burning rate increased as compared with a cigarette having a normal wrapping paper, and the number of cigarettes smoked (that is, the number of times it takes to smoke up to a predetermined cigarette butt length). There is a tendency to decrease. Cigarette smoking can relax the smoker and provide a certain amount of time. Therefore, the number of smoking is one of cigarette performance important for smokers.
 したがって、本発明は、喫煙物品に配合した際に、喫煙回数を減少させることなく、喫煙物品から生成される副流煙を低減することができるたばこ刻を提供することを目的とする。 Therefore, an object of the present invention is to provide a cigarette that can reduce sidestream smoke generated from a smoking article without reducing the number of times of smoking when blended with the smoking article.
 本発明の一つの側面によれば、たばこ刻に含まれる成分を含有するたばこ抽出液およびたばこ刻から選択される反応対象を、スルホ基を有する固体酸触媒および硫酸から選択される反応関与物質と、3.5以下のpHを有する反応混合液が得られるように混合して、前記たばこ刻に含まれる成分の反応を生じさせることを含む、喫煙物品配合用たばこ刻の製造方法が提供される。 According to one aspect of the present invention, a cigarette extract containing components contained in a cigarette cut and a reaction target selected from the cigarette cut are selected from a solid acid catalyst having a sulfo group and a reaction participant selected from sulfuric acid. And a method for producing a tobacco product for smoking articles comprising mixing the components so as to obtain a reaction mixture having a pH of 3.5 or less to cause a reaction of the components contained in the tobacco product. .
 別の側面によれば、前述の方法により得られる喫煙物品配合用たばこ刻が提供される。 According to another aspect, a cigarette for smoking article blend obtained by the above-described method is provided.
 更に別の側面によれば、前述の喫煙物品配合用たばこ刻を含む喫煙物品が提供される。 According to still another aspect, there is provided a smoking article including the above-described tobacco for compounding smoking articles.

Drying the mixture 10 to produce a tobacco cut 11 for blending smoking articles.
 第1の実施形態では、まず、たばこ刻1を水2での抽出工程に晒し、たばこ刻1に含まれる成分(以下、たばこ成分ともいう)を水2で抽出する。これにより、たばこ成分と水とを含んだたばこ抽出液3と、たばこ成分が抽出されたたばこ刻を含んだ抽出残渣4とが生成される。 In the first embodiment, cigarette time 1 is first subjected to an extraction process with water 2, and components contained in cigarette time 1 (hereinafter also referred to as tobacco components) are extracted with water 2. Thereby, the tobacco extract 3 containing a tobacco component and water and the extraction residue 4 containing the tobacco cut from which the tobacco component was extracted are produced | generated.
 たばこ刻1は、喫煙物品に配合される準備が整ったたばこ刻を使用することができる。たばこ刻1は、任意の品種のものを使用することができ、たとえば黄色種、バーレー種、オリエント種などのものを使用することができる。たばこ刻1は、単一品種のものを使用してもよいし、異なる品種の混合物を使用してもよい。たばこ刻1は、除骨葉、中骨、及びこれら原料から構成される再生たばこ(すなわち、工場の作業工程で生じる葉屑、刻み屑、中骨屑、細粉などを再使用可能な形状に加工したたばこ材料)などを含むことができる。「喫煙物品に配合される準備が整ったたばこ刻」とは、農家での乾燥工程、その後の原料工場での1年ないし数年の長期熟成工程、およびその後の製造工場でのブレンドおよび裁刻など種々の加工処理を経て、喫煙物品に配合される準備が整ったたばこ刻を指す。喫煙物品がシガレットの場合、「喫煙物品に配合される準備が整ったたばこ刻」は、「シガレットの巻上げ工程に使用される準備が整ったたばこ刻」である。 Tobacco 1 can be a tobacco that is ready to be blended into a smoking article. Tobacco stamp 1 can be of any variety, such as yellow, Burley, orient. Tobacco stamp 1 may be a single variety or a mixture of different varieties. Tobacco stamp 1 is a reusable tobacco composed of deboned leaves, middle bones, and these raw materials (that is, leaf scraps, shredded chips, middle bone scraps, fine powder, etc. generated in the factory work process can be reused) Processed tobacco material) and the like. “Tobacco ready to be blended into smoking articles” means a drying process at a farmer, followed by a long-term aging process for one to several years at a raw material factory, and subsequent blending and cutting at a manufacturing factory. It refers to cigarettes that are ready to be blended into smoking articles through various processing. When the smoking article is a cigarette, the “cigarette engraved ready to be blended into the smoking article” is the “cigarette engraved ready to be used in the cigarette winding process”.
 抽出は、たばこ刻1を15~100℃の水に0.5~2時間浸漬することにより行うことができる。抽出の際に、たばこ刻1は、抽出溶媒としての水2に対して例えば10質量%の量で使用され得る。 Extraction can be performed by immersing tobacco 1 in water at 15 to 100 ° C. for 0.5 to 2 hours. During the extraction, the tobacco 1 can be used in an amount of, for example, 10% by mass with respect to the water 2 as the extraction solvent.
 抽出後に、たばこ抽出液3を抽出残渣4から分離する。分離は、たとえば、たばこ抽出液3を抽出残渣4から分離可能な篩を用いて行うことができる。 After the extraction, the tobacco extract 3 is separated from the extraction residue 4. Separation can be performed, for example, using a sieve capable of separating the tobacco extract 3 from the extraction residue 4.
 分離されたたばこ抽出液3を、スルホ基を有する固体酸触媒5aと、3.5以下のpHを有する反応混合液6が得られるように混合する。ここで、スルホ基を有する固体酸触媒5aは、固体の表面上にスルホ基が存在し、スルホ基が触媒活性点として作用する触媒をいう。スルホ基を有する固体酸触媒5aは、好ましくは粒子の形態を有する。スルホ基を有する固体酸触媒5aとして、たとえばテイカキュアSAC-6(テイカ株式会社、平均粒径:200μm、比表面積:450m2/g)を使用することができる。スルホ基を有する固体酸触媒5aは、3.5以下のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。スルホ基を有する固体酸触媒5aは、好ましくは1.0~3.5のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。スルホ基を有する固体酸触媒5aは、より好ましくは1.7~3.5のpH、更に好ましくは1.7~2.5のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。たとえば、スルホ基を有する固体酸触媒5aは、たばこ抽出液3に対して、1~20質量%の量で使用することができる。後述の実施例で実証されるとおり、調製された反応混合液6のpHが3.5を超えると、この反応混合液6を用いて製造されたたばこ刻11は、副流煙の低減効果を十分に達成することができない。 The separated tobacco extract 3 is mixed with a solid acid catalyst 5a having a sulfo group so as to obtain a reaction mixture 6 having a pH of 3.5 or less. Here, the solid acid catalyst 5a having a sulfo group refers to a catalyst in which a sulfo group is present on the surface of a solid and the sulfo group acts as a catalyst active site. The solid acid catalyst 5a having a sulfo group preferably has a particle form. As the solid acid catalyst 5a having a sulfo group, for example, Teica Cure SAC-6 (Taika Corporation, average particle size: 200 μm, specific surface area: 450 m 2 / g) can be used. The solid acid catalyst 5a having a sulfo group is added to the tobacco extract 3 in such an amount that a reaction mixture 6 having a pH of 3.5 or less is obtained. The solid acid catalyst 5a having a sulfo group is preferably added to the tobacco extract 3 in such an amount that a reaction mixture 6 having a pH of 1.0 to 3.5 is obtained. The solid acid catalyst 5a having a sulfo group is preferably used in an amount such that a reaction mixture 6 having a pH of 1.7 to 3.5, more preferably 1.7 to 2.5 is obtained. It is added to the extract 3. For example, the solid acid catalyst 5a having a sulfo group can be used in an amount of 1 to 20% by mass with respect to the tobacco extract 3. As demonstrated in the examples described later, when the pH of the prepared reaction mixture 6 exceeds 3.5, the tobacco 11 manufactured using the reaction mixture 6 has an effect of reducing sidestream smoke. It cannot be fully achieved.
 なお、本発明において、反応混合液6は、3.5以下のpHを有するように調製されるが、反応後の反応混合液7が、必ずしも3.5以下のpHを有している必要はない。 In the present invention, the reaction mixture 6 is prepared so as to have a pH of 3.5 or less, but the reaction mixture 7 after the reaction does not necessarily have to have a pH of 3.5 or less. Absent.
 調製された反応混合液6を所定の時間置くことにより、反応混合液6中に含まれるたばこ成分の反応を生じさせることができる。反応は、反応混合液6を、15~40℃で0.5~4時間静置することにより行ってもよいし、反応混合液6を、15~40℃で0.5~4時間撹拌しながら置くことにより行ってもよい。この反応で、たばこ刻に含まれる成分である多糖類、アミノ酸等が、スルホ基を有する固体酸触媒5aにより、脱水縮合することが予測される。 The reaction of the tobacco component contained in the reaction mixture 6 can be caused by placing the prepared reaction mixture 6 for a predetermined time. The reaction may be performed by allowing the reaction mixture 6 to stand at 15 to 40 ° C. for 0.5 to 4 hours, or stirring the reaction mixture 6 at 15 to 40 ° C. for 0.5 to 4 hours. It may be done by placing it. In this reaction, it is predicted that polysaccharides, amino acids, and the like, which are components contained in tobacco, are dehydrated and condensed by the solid acid catalyst 5a having a sulfo group.
 反応後の反応混合液7から固体酸触媒5aを除去して、反応後のたばこ抽出液8を得る。固体酸触媒5aの除去は、たとえば、吸引濾過により行うことができる。 The solid acid catalyst 5a is removed from the reaction mixture 7 after the reaction to obtain a tobacco extract 8 after the reaction. The removal of the solid acid catalyst 5a can be performed, for example, by suction filtration.
 得られたたばこ抽出液8を濃縮することによりたばこ抽出液8から水2を除去する。濃縮することにより水2を除去する工程は、反応後のたばこ抽出液8の液量が、たとえば100分の1~4分の1になる程度まで行うことができる。この工程で、一般的には、たばこ抽出液8から大量の水2が除去されるが、水2の全量が除去されるわけではない。 The water 2 is removed from the tobacco extract 8 by concentrating the tobacco extract 8 obtained. The step of removing the water 2 by concentrating can be performed until the amount of the tobacco extract 8 after the reaction becomes, for example, about 1/100 to 1/4. In this step, a large amount of water 2 is generally removed from the tobacco extract 8, but the total amount of water 2 is not removed.
 濃縮することにより水2が除去されたたばこ抽出液(処理液9)を、抽出工程で得られた抽出残渣4と混合する。処理液9は、処理液9に対して40~100質量%の量の抽出残渣4と混合され得る。ただし、この混合工程において、処理液9の量は、抽出残渣4と同時に得られたたばこ抽出液3から得られた処理液9の量を超えないことが望ましい。 The tobacco extract (treatment liquid 9) from which the water 2 has been removed by concentration is mixed with the extraction residue 4 obtained in the extraction step. The treatment liquid 9 can be mixed with the extraction residue 4 in an amount of 40 to 100% by mass with respect to the treatment liquid 9. However, in this mixing step, it is desirable that the amount of the treatment liquid 9 does not exceed the amount of the treatment liquid 9 obtained from the tobacco extract 3 obtained simultaneously with the extraction residue 4.
 得られた混合物10を乾燥させて、喫煙物品配合用たばこ刻11を製造する。乾燥は、たばこ刻が、当該技術分野で喫煙物品に一般に使用されるたばこ刻と同程度の水分含量を有するようになるまで行われる。乾燥は、一般に、乾燥後のたばこ刻11の水分含量が6~14質量%になるまで行われる。たとえば、乾燥は、混合物10を20~25℃の温度および60~70%の湿度の条件下に、2日間静置することにより行うことができる。 The resulting mixture 10 is dried to produce a tobacco cut 11 for blending smoking articles. Drying is performed until the cigarette has a moisture content similar to that typically used for smoking articles in the art. Drying is generally performed until the moisture content of the tobacco 11 after drying becomes 6 to 14% by mass. For example, the drying can be performed by allowing the mixture 10 to stand at a temperature of 20 to 25 ° C. and a humidity of 60 to 70% for 2 days.

Specifically, the method according to the second embodiment is:
Extracting the components contained in tobacco 1 with water 2 to produce a mixture of tobacco extract 3 containing the components and water and extraction residue 4 containing the tobacco from which the components were extracted To do
Separating the tobacco extract 3 from the extraction residue 4;
Mixing the separated tobacco extract 3 with sulfuric acid 5b so as to obtain a reaction mixture 6 having a pH of 3.5 or less to cause a reaction of the components;

Mixing the resulting treatment liquid 9 with the extraction residue 4 to obtain a mixture 10;
Drying the mixture 10 to produce a tobacco cut 11 for blending smoking articles. In addition, this series of steps may further include a step of removing sulfate ions from the reaction mixture 7 after the reaction. The removal of sulfate ions can be carried out, for example, by adding an anion exchange resin to the reaction mixture 7 after the reaction and reacting it sufficiently to remove the sulfate ions.
 第2の実施形態では、まず、第1の実施形態と同様の手法に従ってたばこ抽出液3を得る。 In the second embodiment, first, the tobacco extract 3 is obtained according to the same method as in the first embodiment.
 得られたたばこ抽出液3を、硫酸5bと、3.5以下のpHを有する反応混合液6が得られるように混合する。硫酸5bは、3.5以下のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。硫酸5bは、好ましくは1.0~3.5のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。硫酸5bは、より好ましくは1.7~3.5のpH、更に好ましくは1.7~2.5のpHを有する反応混合液6が得られるような量で、たばこ抽出液3に添加される。添加される硫酸5bは、たとえば、0.1~98質量%の濃度を有するものを使用することができる。たとえば、21質量%の濃度を有する硫酸5bは、たばこ抽出液3に対して、1~10質量%の量で使用することができる。後述の実施例で実証されるとおり、調製された反応混合液6のpHが3.5を超えると、この反応混合液6を用いて製造されたたばこ刻11は、副流煙の低減効果を十分に達成することができない。 The obtained tobacco extract 3 is mixed with sulfuric acid 5b so as to obtain a reaction mixture 6 having a pH of 3.5 or less. Sulfuric acid 5b is added to the tobacco extract 3 in such an amount that a reaction mixture 6 having a pH of 3.5 or less is obtained. The sulfuric acid 5b is preferably added to the tobacco extract 3 in such an amount that a reaction mixture 6 having a pH of 1.0 to 3.5 is obtained. The sulfuric acid 5b is added to the tobacco extract 3 in such an amount that a reaction mixture 6 having a pH of 1.7 to 3.5, more preferably 1.7 to 2.5 is obtained. The As the added sulfuric acid 5b, for example, one having a concentration of 0.1 to 98% by mass can be used. For example, sulfuric acid 5b having a concentration of 21% by mass can be used in an amount of 1 to 10% by mass with respect to the tobacco extract 3. As demonstrated in the examples described later, when the pH of the prepared reaction mixture 6 exceeds 3.5, the tobacco 11 manufactured using the reaction mixture 6 has an effect of reducing sidestream smoke. It cannot be fully achieved.
 調製された反応混合液6を所定の時間置くことにより、反応混合液6中に含まれるたばこ成分の反応を生じさせることができる。反応は、反応混合液6を、15~40℃で0.5~4時間静置することにより行ってもよいし、反応混合液6を、15~40℃で0.5~4時間撹拌しながら置くことにより行ってもよい。この反応で、たばこ刻に含まれる成分である多糖類、アミノ酸等が、硫酸5bにより、脱水縮合することが予測される。 The reaction of the tobacco component contained in the reaction mixture 6 can be caused by placing the prepared reaction mixture 6 for a predetermined time. The reaction may be performed by allowing the reaction mixture 6 to stand at 15 to 40 ° C. for 0.5 to 4 hours, or stirring the reaction mixture 6 at 15 to 40 ° C. for 0.5 to 4 hours. It may be done by placing it. In this reaction, it is predicted that polysaccharides, amino acids, and the like, which are components contained in tobacco, will undergo dehydration condensation with sulfuric acid 5b.
 反応後の反応混合液7を濃縮することにより反応混合液7から水2を除去する。濃縮することにより水2を除去する工程は、反応後の反応混合液7の液量が、たとえば100分の1~4分の1になる程度まで行うことができる。この工程で、一般的には、反応混合液7から大量の水2が除去されるが、水2の全量が除去されるわけではない。 The water 2 is removed from the reaction mixture 7 by concentrating the reaction mixture 7 after the reaction. The step of removing the water 2 by concentrating can be performed until the amount of the reaction mixture 7 after the reaction becomes, for example, about 1/100 to 1/4. In this step, a large amount of water 2 is generally removed from the reaction mixture 7, but not all of the water 2 is removed.
 濃縮することにより水2が除去された反応混合液(処理液9)を、抽出工程で得られた抽出残渣4と混合する。処理液9は、処理液9に対して40~100質量%の量の抽出残渣4と混合され得る。ただし、この混合工程において、処理液9の量は、抽出残渣4と同時に得られたたばこ抽出液3から得られた処理液9の量を超えないことが望ましい。 The reaction mixture (treatment liquid 9) from which water 2 has been removed by concentration is mixed with the extraction residue 4 obtained in the extraction step. The treatment liquid 9 can be mixed with the extraction residue 4 in an amount of 40 to 100% by mass with respect to the treatment liquid 9. However, in this mixing step, it is desirable that the amount of the treatment liquid 9 does not exceed the amount of the treatment liquid 9 obtained from the tobacco extract 3 obtained simultaneously with the extraction residue 4.
 得られた混合物10を、第1の実施形態と同様の手法に従って乾燥させて、喫煙物品配合用たばこ刻11を製造する。 The obtained mixture 10 is dried according to the same method as in the first embodiment, and the tobacco 11 for blending smoking articles is manufactured.

 第4の実施形態では、まず、たばこ刻1を、硫酸5bと、3.5以下のpHを有する反応混合液6が得られるように混合する。硫酸5bは、たとえば、0.1~98質量%の濃度を有するものを使用することができる。硫酸5bは、3.5以下のpHを有する反応混合液6が得られるような量で、たばこ刻1と混合される。硫酸5bは、好ましくは1.0~3.5のpHを有する反応混合液6が得られるような量で、たばこ刻1と混合される。硫酸5bは、より好ましくは1.7~3.5のpH、更に好ましくは1.7~2.5のpHを有する反応混合液6が得られるような量で、たばこ刻1と混合される。たとえば、21質量%の濃度を有する硫酸5bは、たばこ刻1に対して、1~20質量%の量で使用することができる。後述の実施例で実証されるとおり、調製された反応混合液6のpHが3.5を超えると、この反応混合液6を用いて製造されたたばこ刻11は、副流煙の低減効果を十分に達成することができない。 In the fourth embodiment, the tobacco 1 is first mixed with the sulfuric acid 5b so that a reaction mixture 6 having a pH of 3.5 or less is obtained. As the sulfuric acid 5b, for example, one having a concentration of 0.1 to 98% by mass can be used. The sulfuric acid 5b is mixed with the tobacco 1 in such an amount that a reaction mixture 6 having a pH of 3.5 or less is obtained. The sulfuric acid 5b is mixed with the tobacco 1 in such an amount that a reaction mixture 6 having a pH of 1.0 to 3.5 is obtained. Sulfuric acid 5b is mixed with tobacco 1 in such an amount that a reaction mixture 6 having a pH of 1.7 to 3.5, more preferably 1.7 to 2.5 is obtained. . For example, the sulfuric acid 5b having a concentration of 21% by mass can be used in an amount of 1 to 20% by mass with respect to the tobacco cut 1. As demonstrated in the examples described later, when the pH of the prepared reaction mixture 6 exceeds 3.5, the tobacco 11 manufactured using the reaction mixture 6 has an effect of reducing sidestream smoke. It cannot be fully achieved.
 調製された反応混合液6を所定の時間置くことにより、たばこ刻1に含まれるたばこ成分の反応を生じさせることができる。反応は、反応混合液6を、15~40℃で0.5~4時間静置することにより行ってもよいし、反応混合液6を、15~40℃で0.5~4時間撹拌しながら置くことにより行ってもよい。この反応で、たばこ刻に含まれる成分である多糖類、アミノ酸等が、硫酸5bにより、脱水縮合することが予測される。 The reaction of the tobacco component contained in the tobacco 1 can be caused by placing the prepared reaction mixture 6 for a predetermined time. The reaction may be performed by allowing the reaction mixture 6 to stand at 15 to 40 ° C. for 0.5 to 4 hours, or stirring the reaction mixture 6 at 15 to 40 ° C. for 0.5 to 4 hours.

 2.喫煙物品配合用たばこ刻
 一般的には、本発明の喫煙物品配合用たばこ刻は、たばこ刻中のカーボン含有割合が0.50未満であり、かつ、たばこ刻を窒素雰囲気下で500℃において10分間加熱し、その後冷却して22℃で0.5時間維持することにより得られる炭化物中のカーボン含有割合(以下、「炭化物中のカーボン含有割合」ともいう)が0.50以上であることにより特徴づけられる。
2. Cigarette engraved for smoking articles In general, the cigarette engraved for smoking articles of the present invention has a carbon content of less than 0.50 in the cigarette engraved, and the cigarette engraved at 500 ° C. in a nitrogen atmosphere at 500 ° C. When the carbon content in the carbide obtained by heating for 30 minutes and then cooling and maintaining at 22 ° C. for 0.5 hour (hereinafter also referred to as “carbon content in the carbide”) is 0.50 or more. Characterized.
 好ましい態様において、本発明の喫煙物品配合用たばこ刻は、「たばこ刻中のカーボン含有割合」が、0.30以上、0.50未満であり、かつ、「炭化物中のカーボン含有割合」が、0.50以上、0.58未満であることにより特徴づけられる。 In a preferred embodiment, the tobacco for smoking article blending of the present invention has a "carbon content ratio in the tobacco" of 0.30 or more and less than 0.50, and a "carbon content ratio in the carbide" It is characterized by being 0.50 or more and less than 0.58.
 一方、通常のたばこ刻は、一般に、たばこ刻中のカーボン含有割合が、0.30以上、0.50未満であり、かつ、たばこ刻を窒素雰囲気下で500℃において10分間加熱し、その後冷却して22℃で0.5時間維持することにより得られる炭化物中のカーボン含有割合(「炭化物中のカーボン含有割合」)が、0.40以上、0.50未満であることにより特徴づけられる。本明細書において「通常のたばこ刻」は、本発明の方法の出発材料として使用されるたばこ刻、すなわち本発明の方法で処理されていないたばこ刻を指す。 On the other hand, in general cigarettes, generally, the carbon content in the cigarettes is 0.30 or more and less than 0.50, and the cigarettes are heated at 500 ° C. for 10 minutes in a nitrogen atmosphere, and then cooled. Thus, the carbon content in the carbide obtained by maintaining at 22 ° C. for 0.5 hour (“carbon content in the carbide”) is characterized by being 0.40 or more and less than 0.50. As used herein, “regular cigarette” refers to a cigarette used as a starting material for the method of the present invention, that is, a cigarette that has not been treated by the method of the present invention.
 したがって、一般的には、本発明の喫煙物品配合用たばこ刻は、通常のたばこ刻と同程度の「たばこ刻中のカーボン含有割合」を有し、かつ、通常のたばこ刻から得られる炭化物よりも高い「炭化物中のカーボン含有割合」を有することにより特徴づけられる。 Therefore, in general, the cigarette for smoking article blending of the present invention has a "carbon content ratio in the cigarette" that is comparable to that of a normal cigarette and is obtained from a carbide obtained from a normal cigarette. Is also characterized by having a high “carbon content in carbides”.
 「カーボン含有割合」は、燃えにくさの指標であると考えられる。また、炭化物を得るために使用される500℃の加熱温度は、自然燃焼時のシガレットの燃焼温度とほぼ同程度の温度である。したがって、「炭化物中のカーボン含有割合」が高いことは、たばこ刻が、自然燃焼時に燃えにくいことを示す。 “Carbon content” is considered to be an index of incombustibility. Further, the heating temperature of 500 ° C. used for obtaining the carbide is approximately the same as the cigarette combustion temperature during natural combustion. Therefore, a high “carbon content ratio in the carbide” indicates that the tobacco is difficult to burn during natural combustion.
 以上より、たばこ刻中のカーボン含有割合が0.50未満であり、かつ、炭化物中のカーボン含有割合が0.50以上であるという特徴は、たばこ刻が、自然燃焼時に燃えにくく、喫煙物品から生成される副流煙の量が少ないことを意味する。 From the above, the feature that the carbon content in the tobacco is less than 0.50 and the carbon content in the carbide is 0.50 or more is that the tobacco is less likely to burn during natural combustion, and from the smoking article This means that the amount of sidestream smoke produced is small.
 「たばこ刻中のカーボン含有割合」および「炭化物中のカーボン含有割合」は、元素分析装置を用いて測定することができる。たとえば、元素分析装置SUMIGRAPH NCH-22F(株式会社住化分析センター製)を用いて測定することができる。 “The carbon content in the tobacco” and “the carbon content in the carbide” can be measured using an elemental analyzer. For example, it can be measured using an elemental analyzer SUMIGRAPH NCH-22F (manufactured by Sumika Chemical Analysis Co., Ltd.).
 「カーボン含有割合」は、具体的には、以下のとおり測定することができる。たばこ刻または炭化物を、調和環境下(22℃、60%相対湿度)で24時間以上蔵置し、たばこ刻または炭化物の0.01gを秤量し、800℃まで酸化雰囲気下で加熱し、得られた燃焼生成物を元素分析装置で分析して元素組成を求める。炭素と水素のリファレンスとして結晶セルロースを用いる。リファレンスを用いることで、燃焼生成物のカーボン割合を直接測定することができる。 The “carbon content ratio” can be specifically measured as follows. Tobacco or carbide was stored for 24 hours or more in a harmonious environment (22 ° C, 60% relative humidity), 0.01 g of tobacco or carbide was weighed and heated to 800 ° C in an oxidizing atmosphere. The combustion product is analyzed with an elemental analyzer to determine the elemental composition. Crystalline cellulose is used as a reference for carbon and hydrogen. By using the reference, the carbon ratio of the combustion product can be directly measured.
 3.喫煙物品
 本発明の喫煙物品配合用たばこ刻は、任意の喫煙物品、一般的には燃焼型の喫煙物品、たとえばシガレット、パイプ、キセル、葉巻、シガリロなどに使用することができる。
3. Smoking Article The tobacco tobacco for smoking article blending of the present invention can be used for any smoking article, generally a combustion type smoking article, such as a cigarette, pipe, xel, cigar, cigarillo, and the like.
 配合割合は、限定されないが、本発明の喫煙物品配合用たばこ刻が、喫煙物品に含まれる全たばこ刻(以下、たばこ充填材ともいう)の全体(100質量%)を占めるように配合されてもよいし、たばこ充填材の一部分、たとえばたばこ充填材の50~75質量%を占めるように配合されてもよい。 The blending ratio is not limited, but the cigarette for smoking article blending of the present invention is blended so as to occupy the whole (100% by mass) of all cigarettes included in the smoking article (hereinafter also referred to as tobacco filler). Alternatively, it may be blended so as to occupy a part of the tobacco filler, for example, 50 to 75% by mass of the tobacco filler.
 前者の場合、たばこ充填材が自然燃焼時にきわめて燃えにくく、副流煙を著しく低減することができる。ただし、この場合、吸煙燃焼時にもたばこ充填材が燃えにくくなり、その結果、喫煙回数が通常のたばこ刻より多少増える可能性がある。一方、後者の場合、本発明の喫煙物品配合用たばこ刻は、通常のたばこ刻と混合されているため、たばこ充填材が自然燃焼時に燃えにくく、副流煙を低減することができるという効果と、吸煙燃焼時には通常のたばこ刻と同様に燃えることを保証することができるという効果を併せ持つことができる。 In the former case, the tobacco filler is extremely difficult to burn during natural combustion, and sidestream smoke can be significantly reduced. However, in this case, the tobacco filler becomes difficult to burn even during smoke-absorbing combustion, and as a result, the number of times of smoking may slightly increase from that of normal tobacco. On the other hand, in the latter case, the cigarette engraved with a smoking article of the present invention is mixed with a normal cigarette engraving, so that the tobacco filler is less likely to burn during natural combustion and can reduce sidestream smoke. In addition, at the time of smoke-absorbing combustion, it can have the effect of being able to ensure that it burns in the same way as a normal cigarette.
 以上より、本発明の喫煙物品は、喫煙回数を減少させることなく、喫煙物品から生成される副流煙を低減することができるという効果を奏する。 As described above, the smoking article of the present invention has an effect that the sidestream smoke generated from the smoking article can be reduced without reducing the number of times of smoking.

 実施例1-1乃至1-4、並びに比較例1-1および1-2では、反応対象としてたばこ抽出液を使用し、反応関与物質として、スルホ基を有する固体酸触媒を使用した。これらの実験結果から、たばこ抽出液と固体酸触媒とを含む反応混合液のpHを所定の値(3.5)以下にして、たばこ刻に含まれる成分の反応を生じさせると、得られたたばこ刻は、喫煙回数を減少させることなく、シガレットから生成される副流煙を低減することができることが分かる。 In Examples 1-1 to 1-4 and Comparative Examples 1-1 and 1-2, a tobacco extract was used as a reaction target, and a solid acid catalyst having a sulfo group was used as a reaction participant. From these experimental results, it was obtained when the reaction mixture containing the tobacco extract and the solid acid catalyst was brought to a predetermined value (3.5) or less to cause the reaction of the components contained in the tobacco. It can be seen that cigarette time can reduce sidestream smoke generated from cigarettes without reducing the number of smokers.
 実施例2-1、および比較例2-1乃至2-3では、反応対象としてたばこ刻を使用し、反応関与物質として硫酸を使用した。これらの実験結果も、たばこ刻と硫酸とを含む反応混合液のpHを所定の値(3.5)以下にして、たばこ刻に含まれる成分の反応を生じさせると、得られたたばこ刻は、喫煙回数を減少させることなく、シガレットから生成される副流煙を低減することができることを示す。 In Example 2-1, and Comparative Examples 2-1 to 2-3, cigarette time was used as a reaction target, and sulfuric acid was used as a reaction participant. These experimental results also show that when the pH of the reaction mixture containing tobacco and sulfuric acid is set to a predetermined value (3.5) or less to cause a reaction of components contained in the tobacco, the obtained tobacco is It shows that sidestream smoke generated from cigarettes can be reduced without reducing the number of smoking.
 実施例3-1では、反応対象としてたばこ抽出液を使用し、反応関与物質として硫酸を使用した。この実験も、たばこ抽出液と硫酸とを含む反応混合液のpHを所定の値(3.5)以下にして、たばこ刻に含まれる成分の反応を生じさせると、得られたたばこ刻は、喫煙回数を減少させることなく、シガレットから生成される副流煙を低減することができることを示す。 In Example 3-1, a tobacco extract was used as a reaction target, and sulfuric acid was used as a reaction participant. In this experiment as well, when the reaction mixture containing the tobacco extract and sulfuric acid is brought to a predetermined value (3.5) or less to cause the reaction of the components contained in the tobacco, the obtained tobacco It shows that sidestream smoke generated from cigarettes can be reduced without reducing the number of smokers.
 また、実施例1-1乃至1-3の結果から、以下のことが分かる。本発明の方法により得られたたばこ刻を100質量%の配合割合でシガレットに配合すると、たばこ刻が自然燃焼時にきわめて燃えにくく、副流煙を著しく低減することができる。一方、本発明の方法により得られたたばこ刻を、通常のたばこ刻と混合して50~75質量%の配合割合でシガレットに配合すると、たばこ刻が自然燃焼時に燃えにくく、副流煙を低減することができるという効果と、吸煙燃焼時には通常のたばこ刻と同様の燃えやすさで燃焼することができるという効果を併せ持つことができる。 Further, the following can be understood from the results of Examples 1-1 to 1-3. When the cigarette cut obtained by the method of the present invention is blended with cigarette at a blending ratio of 100% by mass, the cigarette cut is extremely difficult to burn during natural combustion, and the sidestream smoke can be significantly reduced. On the other hand, when cigarettes obtained by the method of the present invention are mixed with ordinary cigarettes and blended in cigarettes at a blending ratio of 50 to 75% by mass, the cigarettes are less likely to burn during natural combustion, reducing sidestream smoke. It is possible to have both the effect of being able to burn, and the effect of being able to burn with the same flammability as a normal cigarette at the time of smoke absorption combustion.
 また、比較例4-1乃至4-5の結果から、硫酸の代わりに硝酸を使用して反応混合液のpH所定の値(3.5)以下にして、たばこ刻に含まれる成分の反応を生じさせたとしても、シガレットから生成される副流煙を低減できないことが分かる。 Further, from the results of Comparative Examples 4-1 to 4-5, the reaction of the components contained in the tobacco was carried out by using nitric acid instead of sulfuric acid so that the pH of the reaction mixture was a predetermined value (3.5) or less. Even if it makes it generate | occur | produce, it turns out that the sidestream smoke produced | generated from a cigarette cannot be reduced.
 また、実施例1-1乃至1-3、実施例2-1、実施例3-1、および参考例の結果から、本発明の方法により得られたたばこ刻は、通常のたばこ刻と比較して、喫煙回数を減少させることなく、シガレットから生成される副流煙を低減することができることが分かる。 Further, from the results of Examples 1-1 to 1-3, Example 2-1, Example 3-1, and the reference example, the tobacco engraved obtained by the method of the present invention is compared with the ordinary tobacco engraving. Thus, it is understood that the sidestream smoke generated from the cigarette can be reduced without reducing the number of times of smoking.
