Description

添加剤を含有する燃焼型喫煙物品およびその製造方法Combustion-type smoking article containing additive and method for producing same

　本発明は、添加剤を含有する燃焼型喫煙物品およびその製造方法に関する。 The present invention relates to a combustible smoking article containing an additive and a method for producing the same.

　燃焼型喫煙物品において、タール値が増加すると喫味阻害感も増加する。このため喫味阻害感を和らげることが提案されている。例えば、特許文献１は、ＰＧ（プロピレングリコール）とＶＧ（ベジタブルグリセリン）を添加したタバコ原料を含み、前記タバコ原料において、ＰＧとＶＧが５～５０重量％、水分が５～１０重量％であることを特徴とする両用型紙巻きタバコのタバコ充填物を開示する。当該タバコ充填物は煙をより柔らかくして、口当たりをより快適にするとされる。 In combustible smoking articles, as the tar value increases, the smoking taste inhibition also increases. For this reason, proposals have been made to alleviate this taste inhibition. For example, Patent Document 1 discloses a tobacco filler for dual-use cigarettes that contains tobacco raw material to which PG (propylene glycol) and VG (vegetable glycerin) have been added, and that is characterized in that the tobacco raw material contains 5-50% by weight of PG and VG and 5-10% by weight of moisture. The tobacco filler is said to make the smoke softer and more pleasant to the palate.

　本発明によってニコチン含有量が高く、かつ喫味阻害感が低い燃焼型喫煙物品を提供できる。 The present invention provides a combustible smoking article that has a high nicotine content and a low taste inhibition.

１．燃焼型喫煙物品
　本実施形態にかかる燃焼型喫煙物品は、たばこ材料（Ａ）と添加剤（Ｂ）とを含むたばこロッドを備える。前記たばこ材料（Ａ）は高ニコチン原料（Ａ１）を含む。高ニコチン原料（Ａ１）は、５．０～８．０重量％のニコチンを含有する。添加剤（Ｂ）は、高ニコチン原料（Ａ１）に対し２０～６０重量％の量で存在する。本開示において「Ｘ～Ｙ」はその端値であるＸおよびＹを含む。 1. Combustion-type smoking article The combustion-type smoking article according to this embodiment includes a tobacco rod containing a tobacco material (A) and an additive (B). The tobacco material (A) includes a high-nicotine raw material (A1). The high-nicotine raw material (A1) contains 5.0 to 8.0% by weight of nicotine. The additive (B) is present in an amount of 20 to 60% by weight of the high-nicotine raw material (A1). In this disclosure, "X to Y" includes the end values X and Y.

　燃焼型喫煙物品とは、燃焼によってエアロゾルを発生させる物品である。燃焼型喫煙物品は、通常、たばこロッドとフィルターを備える。 A combustion smoking article is an article that generates an aerosol through combustion. A combustion smoking article typically includes a tobacco rod and a filter.

（１）たばこロッド
　たばこロッドは、香味発生源である充填物とこれを巻装するラッパーを備える。本実施形態にかかるたばこロッドは、前記たばこ材料（Ａ）と、前記添加剤（Ｂ）を含む。たばこ材料（Ａ）と、添加剤（Ｂ）は、ともに充填物に含まれていてもよく、たばこ材料（Ａ）は充填物に、添加剤（Ｂ）は充填物以外の部位（例えばラッパー）に含まれていてもよい。 (1) Tobacco Rod The tobacco rod includes a filler, which is a flavor generating source, and a wrapper around which the filler is wrapped. The tobacco rod according to this embodiment includes the tobacco material (A) and the additive (B). Both the tobacco material (A) and the additive (B) may be included in the filler, or the tobacco material (A) may be included in the filler and the additive (B) may be included in a portion other than the filler (e.g., the wrapper).

　［たばこ材料（Ａ）］
　１）高ニコチン原料
　たばこ材料は、高ニコチン原料（Ａ１）を必須成分として含む。高ニコチン原料（Ａ１）とは、高濃度のニコチンを含むたばこ原料であり、その由来は限定されない。すなわち、高ニコチン原料（Ａ１）は、たばこ由来であってよく、例えばニコチン含有量が高いたばこ葉などの天然物由来であってもよい。ニコチン含有量が高いたばこ葉としては、限定されないが、フィリピン産Ｓｕｎ　Ａｉｒ　Ｃｕｒｅｄ等が挙げられる。 [Tobacco material (A)]
1) High-nicotine raw material The tobacco material contains a high-nicotine raw material (A1) as an essential component. The high-nicotine raw material (A1) is a tobacco raw material containing a high concentration of nicotine, and its origin is not limited. That is, the high-nicotine raw material (A1) may be derived from tobacco, and may be derived from a natural product such as tobacco leaves with a high nicotine content. Examples of tobacco leaves with a high nicotine content include, but are not limited to, Sun Air Cured from the Philippines.

　高ニコチン原料（Ａ１）は非たばこ由来の材料であってもより。例えば、高ニコチン原料（Ａ１）は、非たばこ由来の材料（刻またはシート等）に、別途調製したニコチンまたはニコチンを含む材料を添加した材料であってよい。前記ニコチンは合成したものであってもよいし、たばこ植物から単離したものであってもよい。前記ニコチンを含む材料としては、たばこ植物を抽出に供して得たたばこ抽出物等が挙げられる。 The high-nicotine raw material (A1) may be a material derived from a non-tobacco source. For example, the high-nicotine raw material (A1) may be a material obtained by adding separately prepared nicotine or a material containing nicotine to a non-tobacco source (such as shreds or sheets). The nicotine may be synthetic or isolated from tobacco plants. Examples of the material containing nicotine include tobacco extracts obtained by subjecting tobacco plants to extraction.

　高ニコチン原料（Ａ１）中のニコチン量は５．０～８．０重量％である。当該ニコチン量が過少であるとユーザーのニーズにマッチしない。一方、当該ニコチン量が過多であると、喫味阻害感が高まるおそれがある。かかる観点から、前記下限値は限定されないが、好ましくは６．０重量％以上であり、前記上限値は限定されないが、好ましくは７．０重量％以下である。ニコチン量は公知の方法で定量できるが、好ましくはサンプルをヘキサン等の無極性有機溶媒を用いた抽出に供し、当該抽出液を、ガスクロマトグラフィーでの分析に供することで定量できる。この際、水素炎イオン化検出器（ＦＩＤ）を用いることが好ましい。 The amount of nicotine in the high-nicotine raw material (A1) is 5.0 to 8.0% by weight. If the amount of nicotine is too low, it will not meet the needs of users. On the other hand, if the amount of nicotine is too high, there is a risk of the smoking taste being inhibited. From this perspective, the lower limit is not limited, but is preferably 6.0% by weight or more, and the upper limit is not limited, but is preferably 7.0% by weight or less. The amount of nicotine can be quantified by a known method, but preferably, the sample is subjected to extraction using a non-polar organic solvent such as hexane, and the extract is subjected to analysis by gas chromatography. In this case, it is preferable to use a flame ionization detector (FID).

　２）たばこ原料（Ａ２）
　たばこ材料（Ａ）は、高ニコチン原料（Ａ１）よりもニコチン含有量が低いたばこ原料（Ａ２）を必要に応じて含む。すなわち、たばこ材料（Ａ）は、一態様において高ニコチン原料（Ａ１）とたばこ原料（Ａ２）を含み、別態様において高ニコチン原料（Ａ１）を含むが、たばこ原料（Ａ２）を含まない。 2) Tobacco raw material (A2)
The tobacco material (A) optionally contains a tobacco material (A2) having a lower nicotine content than the high-nicotine material (A1). That is, in one embodiment, the tobacco material (A) contains the high-nicotine material (A1) and the tobacco material (A2), and in another embodiment, the tobacco material (A) contains the high-nicotine material (A1) but does not contain the tobacco material (A2).

　たばこ材料（Ａ）中のニコチン含有量は、好ましくは１．０～４．０重量％、より好ましくは２．５～４．０重量％である。たばこ材料（Ａ）中のニコチン濃度がこの範囲になるように、高ニコチン原料（Ａ１）とたばこ原料（Ａ２）の量は適宜調整されうる。例えば、たばこ材料（Ａ）は、好ましくは１０～３０重量％の高ニコチン原料（Ａ１）を含有する。当該ニコチン量が過少であるとユーザーのニーズにマッチしない。一方、当該ニコチン量が過多であると、喫味阻害感が高まるおそれがある。かかる観点から、前記下限値は限定されないが、好ましくは１５重量％以上であり、前記上限値は限定されないが、好ましくは２５重量％以下である。 The nicotine content in the tobacco material (A) is preferably 1.0 to 4.0% by weight, more preferably 2.5 to 4.0% by weight. The amounts of the high nicotine raw material (A1) and the tobacco raw material (A2) can be adjusted appropriately so that the nicotine concentration in the tobacco material (A) is within this range. For example, the tobacco material (A) preferably contains 10 to 30% by weight of the high nicotine raw material (A1). If the nicotine amount is too low, it will not meet the needs of users. On the other hand, if the nicotine amount is too high, there is a risk of an increased inhibition of the smoking taste. From this perspective, the lower limit is not limited, but is preferably 15% by weight or more, and the upper limit is not limited, but is preferably 25% by weight or less.

（１）刻の調製
　高ニコチン原料（Ａ１）として、フィリピン産Ｓｕｎ　Ａｉｒ　Ｃｕｒｅｄを準備した。当該材料のニコチン含有量は６．５重量％であった。たばこ原料（Ａ２）として、黄色葉（ＦＣＶ）、オリエント葉（ＯＲＴ）、バーレー葉（ＢＬＹ）を準備し、表１に示すように混合して、たばこ材料（Ａ）刻を調製した。 (1) Preparation of shreds As the high nicotine raw material (A1), Sun Air Cured from the Philippines was prepared. The nicotine content of this material was 6.5% by weight. As the tobacco raw material (A2), yellow leaf (FCV), Orient leaf (ORT), and Burley leaf (BLY) were prepared and mixed as shown in Table 1 to prepare shredded tobacco material (A).

（２）添加剤（Ｂ）
　添加剤としてプロピレングリコール、グリセリンを用い、前記刻に添加した。プロピレングリコールおよびグリセリンの合計添加量は、刻に対して、７．４２重量％とした。 (2) Additive (B)
Propylene glycol and glycerin were used as additives and were added to the chopped material in a total amount of 7.42% by weight based on the amount of the chopped material.

　当該刻を充填した燃焼型喫煙物品を調製し、十分に訓練された５名のパネリストによる喫煙試験に供した。喫味阻害感の程度を１（弱）～１０（強）の数値で評価し、その平均値を求めた。結果を表３に示す。 Combustible smoking articles filled with the tobacco were prepared and subjected to smoking tests by five well-trained panelists. The degree of taste inhibition was evaluated on a scale of 1 (weak) to 10 (strong), and the average score was calculated. The results are shown in Table 3.

　刻中の各成分の量は、刻の抽出物をガスクロマトグラフ分析装置（Ａｇｉｌｅｎｔ製ＧＣ－ＦＩＤ／ＴＣＤ、ＧＣ：７８９０Ｂ）にて分析して求めた。具体的には以下のとおりに実施した。 The amount of each component in the chopped meat was determined by analyzing the chopped meat extract with a gas chromatograph analyzer (Agilent GC-FID/TCD, GC:7890B). Specifically, the procedure was as follows:

　プロピレングリコールおよびグリセリンの分析：２ｇの刻を２５ｍＬのメタノールで抽出した液を、ガスクロマトグラフ分析に供した。刻中のプロピレングリコールおよびグリセリン（ＰＧおよびＧ）の量は、これらを添加する前の刻に元から含まれていたＰＧおよびＧの量と、外添したＰＧおよびＧのうち、添着した分（ロス分を除く）の合計値である。例えば、刻３に元から含まれるＰＧおよびＧの総量は１．８３ｍｇ／ｇであった。実施例１と比較例１の差分から刻に添着したＰＧおよびＧの総量は７１．４５ｍｇ／ｇである。これは、刻３（ブレンドしたたばこ刻）に対して、成分（Ｂ）が７．１４５％添着したことを意味する。同様に、ＰＧおよびＧの添着分は、参考例２では７．２４２％、参考例４では６．９５０％、実施例２では７．３１４％であった。 Analysis of propylene glycol and glycerin: 2 g of shredded tobacco was extracted with 25 mL of methanol and the liquid was subjected to gas chromatographic analysis. The amount of propylene glycol and glycerin (PG and G) in the shredded tobacco is the sum of the amount of PG and G originally contained in the shredded tobacco before the addition of these and the amount of PG and G that was added externally (excluding the amount lost). For example, the total amount of PG and G originally contained in shredded tobacco 3 was 1.83 mg/g. The total amount of PG and G that was added to the shredded tobacco was 71.45 mg/g based on the difference between Example 1 and Comparative Example 1. This means that 7.145% of component (B) was added to shredded tobacco 3 (blended shredded tobacco). Similarly, the amount of PG and G added was 7.242% in Reference Example 2, 6.950% in Reference Example 4, and 7.314% in Example 2.

　ニコチンの分析：まず、１ｇの刻を２０ｍＬの純水で抽出して抽出水を得た。次いで当該抽出水を２０ｍＬのヘキサンを用いた抽出に供し、有機相を分離した。最後に、当該有機相を２０ｍＬの８Ｎ水酸化ナトリウム水溶液を用いた抽出に供し、水相を得た。当該水相をガスクロマトグラフ分析（Ａｇｉｌｅｎｔ製ＧＣ－ＦＩＤ／ＴＣＤ、ＧＣ：７８９０Ｂを使用）に供した。 Nicotine analysis: First, 1 g of chopped nicotine was extracted with 20 mL of pure water to obtain an extract. The extract was then subjected to extraction with 20 mL of hexane to separate the organic phase. Finally, the organic phase was subjected to extraction with 20 mL of 8N aqueous sodium hydroxide solution to obtain an aqueous phase. The aqueous phase was subjected to gas chromatographic analysis (Agilent GC-FID/TCD, GC: 7890B was used).

　煙中の量は、喫煙物品の吸口端にケンブリッジフィルターを接続し、当該物品を喫煙器による喫煙試験に供して求めた。具体的には、自動喫煙器を用いて、自動喫煙し、１パフごとのたばこ煙中粒状物質をケンブリッジフィルター（Ｂｏｒｇｗａｌｄｔ　ＫＣ　Ｉｎｃ．製、ＣＭ－１３３）で捕集した。喫煙試験後のケンブリッジフィルターを、メタノール（和光純薬工業株式会社製、試薬特級）１０ｍＬ中で振盪して分析試料を得た。得られた分析試料１μＬをマイクロシリンジに採取し、ガスクロマトグラフ分析装置（Ａｇｉｌｅｎｔ製ＧＣ－ＦＩＤ／ＴＣＤ、ＧＣ：７８９０Ｂ）にて分析した。 The amount in the smoke was determined by connecting a Cambridge filter to the mouth end of the smoking article and subjecting the article to a smoking test using a smoking machine. Specifically, smoking was performed automatically using an automatic smoking machine, and particulate matter in the tobacco smoke for each puff was collected with a Cambridge filter (CM-133, manufactured by Borgwaldt KC Inc.). After the smoking test, the Cambridge filter was shaken in 10 mL of methanol (special grade reagent, manufactured by Wako Pure Chemical Industries, Ltd.) to obtain an analytical sample. 1 μL of the obtained analytical sample was collected in a microsyringe and analyzed using a gas chromatograph analyzer (GC-FID/TCD, GC: 7890B, manufactured by Agilent).

　添加剤によって喫味阻害感が低減されることが明らかである。 It is clear that additives reduce the unpleasant taste sensation.
