Description

口腔用無煙たばこ及びその製造方法Oral smokeless tobacco and its manufacturing method
　本発明は、口腔用無煙たばこ及びその製造方法に関する。 The present invention relates to oral smokeless tobacco and a method for producing the same.
　口腔内で舐めて香味を味わう口腔用無煙たばことして、例えばたばこ抽出物と砂糖、砂糖代替物とを混錬し、冷却、固化したたばこ飴が知られている（特許文献１等）。このようなたばこ飴において、使用者は、たばこ飴がなくなりかけた時点でたばこ飴を噛んで飲み込むことが想定される。使用者がこのような方法でたばこ飴を使用する場合、たばこ飴がなくなりかけた時点で噛み砕く部分は、適切な噛み心地を有することが望ましい。一方、前記噛み砕く部分は噛んですぐに飲み込まれてしまうため、香味はそれほど求められない。また、たばこ飴の終わりかけ（すなわち、噛み砕ける程度までたばこ飴が小さくなった状態）はわかりにくいため、使用者はたばこ飴が小さくなった段階で、少し歯で噛んでみて、噛み砕けなければもう少し舐め進めて、しばらくして再び噛んでみる、といった動作を繰り返すことが想定される。 As an oral smokeless tobacco that can be licked in the mouth to enjoy the flavor, tobacco candy is known, for example, which is made by kneading tobacco extract, sugar, or a sugar substitute, and cooling and solidifying the mixture (Patent Document 1, etc.). In such tobacco candy, it is assumed that the user chews and swallows the tobacco candy when the tobacco candy is about to run out. When a user uses tobacco candy in this manner, it is desirable that the part that is chewed when the tobacco candy is about to run out has an appropriate chewing feel. On the other hand, since the chewable portion is swallowed immediately after being chewed, flavor is not required as much. In addition, it is difficult to tell when the tobacco candy is about to end (in other words, the tobacco candy has become small enough to be chewed), so when the tobacco candy has become small, try chewing it with your teeth and see if it doesn't break into pieces. It is assumed that the child will lick it a little further and then try biting again after a while, repeating the action.
　一方、口腔用無煙たばこの他の例として、たばこ材料の成型体の周部に空隙を有するコーティング層を設け、該成型体中の成分がコーティング層の空隙を介して口腔内へ運ばれる口腔たばこが知られている（特許文献２）。 On the other hand, as another example of oral smokeless tobacco, a coating layer having voids is provided around the periphery of a molded article of tobacco material, and the components in the molded article are carried into the oral cavity through the voids of the coating layer. is known (Patent Document 2).
特表２０１４－５２６２７８号公報Special table 2014-526278 publication 特表２０１３－５０７１０５号公報Special Publication No. 2013-507105
　しかし、特許文献１に開示された口腔用無煙たばこでは、使用者が無煙たばこの使用完了を認識するのが困難であり、無煙たばこを噛み砕くタイミングが判別しにくい。また、特許文献２に開示された口腔用無煙たばこでは、コーティング層がなくなり使用者が成型体を噛み砕く際に成型体が適切な噛み心地を有さず、更なる改善が望まれる。 However, with the oral smokeless tobacco disclosed in Patent Document 1, it is difficult for the user to recognize when the smokeless tobacco has been used, and it is difficult to determine the timing to chew the smokeless tobacco. Furthermore, in the oral smokeless tobacco disclosed in Patent Document 2, the coating layer is missing and the molded product does not have an appropriate chewing feeling when the user chews the molded product, and further improvements are desired.
　本発明は、使用者が使用完了を容易に認識でき、かつ、使用完了時に口腔内に残留した無煙たばこが適切な噛み心地を有する口腔用無煙たばこを提供することを目的とする。 An object of the present invention is to provide a smokeless tobacco for oral use that allows a user to easily recognize the completion of use, and in which the smokeless tobacco remaining in the oral cavity at the time of completion of use has an appropriate chewing feeling.

　［口腔用無煙たばこ］
　本実施形態に係る口腔用無煙たばこは、粉末を成型した成型体と、前記成型体を外包し、香味成分を含む口腔内で溶解可能なコーティング部と、を備える。ここで、錠剤硬度計を用いて測定される、前記成型体の杭型プランジャによる圧縮破断強度は２０Ｎ以上、２００Ｎ以下である。 [Smokeless tobacco for oral use]
The smokeless tobacco for oral use according to the present embodiment includes a molded body formed by molding powder, and a coating portion that encases the molded body and contains a flavor component and is dissolvable in the oral cavity. Here, the compressive breaking strength of the molded body measured by a pile-shaped plunger using a tablet hardness meter is 20 N or more and 200 N or less.
　本実施形態に係る口腔用無煙たばこでは、使用者がコーティング部を舐め進めていき、成型体が露出することで使用完了を認識する。その後、口腔内に残留した成型体を噛み砕き、飲み込むことで使用が完了する。前記口腔用無煙たばこでは成型体とコーティング部とで表面粗さが異なるため、使用者がコーティング部を舐め進めて成型体が露出した際に、前記表面粗さの相違により使用完了を容易に認識することができる。また、錠剤硬度計を用いて測定される、成型体の杭型プランジャによる圧縮破断強度が２０Ｎ以上、２００Ｎ以下であることにより、成型体をコーティング部で容易にコーティングすることができ、成型体を口腔内で舐めても容易に崩壊してしまうことがなく、かつ、成型体を噛み砕く際に適切な噛み心地を有することができる。 In the oral smokeless tobacco according to this embodiment, the user licks the coating portion and recognizes the completion of use when the molded product is exposed. After that, use is completed by chewing and swallowing the molded product remaining in the oral cavity. In the oral smokeless tobacco, the molded body and the coated part have different surface roughnesses, so when the user licks the coated part and the molded body is exposed, the difference in surface roughness makes it easy to recognize that use is complete. can do. In addition, since the compressive breaking strength of the molded body measured using a tablet hardness tester using a pile-shaped plunger is 20 N or more and 200 N or less, the molded body can be easily coated with the coating portion, and the molded body can be easily coated with the coating portion. Even if the molded product is licked in the oral cavity, it will not easily disintegrate, and the molded product can have an appropriate chewing feeling when being chewed.
　本実施形態に係る口腔用無煙たばこの一例を図１に示す。図１に示される口腔用無煙たばこ１は、成型体２と、成型体２を外包するコーティング部３とを有する。 An example of the oral smokeless tobacco according to this embodiment is shown in FIG. The oral smokeless tobacco 1 shown in FIG. 1 includes a molded body 2 and a coating portion 3 that encases the molded body 2.
　（成型体）
　本実施形態に係る口腔用無煙たばこにおける成型体は、粉末が成型された成型体であれば特に限定されない。粉末としてはたばこ粉末、セルロース粉末、グルコマンナン粉末、キシログルカン粉末等が成型性の観点から好ましい。たばこ粉末の原料（たばこ原料）としては、例えば葉たばこ、葉脈部、幹部、根、花等が挙げられる。葉たばこの種類は特に限定されず、例えば黄色種、バーレー種、在来種、オリエント葉等や、それらの発酵葉等であることができる。これらのたばこ原料は一種を用いてもよく、二種以上を併用してもよい。セルロース粉末としては、市販品では、例えばセルロース粉末（富士フィルム和光純薬、０３６－２２２２５）等が挙げられる。これらのセルロース粉末は一種を用いてもよく、二種以上を併用してもよい。 (molded body)
The molded product in the oral smokeless tobacco according to the present embodiment is not particularly limited as long as it is a molded product made of powder. As the powder, tobacco powder, cellulose powder, glucomannan powder, xyloglucan powder, etc. are preferable from the viewpoint of moldability. Examples of raw materials for tobacco powder (tobacco raw materials) include leaf tobacco, leaf veins, trunks, roots, flowers, and the like. The type of leaf tobacco is not particularly limited, and may include, for example, yellow tobacco, burley tobacco, native tobacco, orient leaf, and fermented leaves thereof. One type of these tobacco raw materials may be used, or two or more types may be used in combination. Examples of commercially available cellulose powder include cellulose powder (Fuji Film Wako Pure Chemical Industries, Ltd., 036-22225). One type of these cellulose powders may be used, or two or more types may be used in combination.
　本実施形態では、特に前記粉末が、たばこ原料から香味成分を含むたばこ抽出液を抽出した後のたばこ残渣であることが好ましい。たばこ抽出液が抽出された後に残るたばこ残渣は香味が乏しいため、通常は廃棄されるか、あるいはたばこ抽出液をかけ戻すための基材として用いられる。ここで、本実施形態において成型体に求められる性質は適度な噛み心地であり、成型体は噛み砕かれた後にすぐに飲み込まれてしまうため、香味は必要とされない。そのため、前記たばこ残渣を、成型体を構成する粉末として用いることができる。通常は廃棄されるたばこ残渣を再利用することができるため、環境負荷を低減でき、またコスト面でも有利である。なお、後述するように、得られるたばこ抽出液はコーティング部の香味成分として使用することができる。 In this embodiment, it is particularly preferable that the powder is tobacco residue after extracting a tobacco extract containing flavor components from tobacco raw materials. The tobacco residue that remains after the tobacco extract is extracted has a poor flavor and is therefore usually discarded or used as a substrate for backing the tobacco extract. Here, in this embodiment, the properties required of the molded product are appropriate chewability, and since the molded product is swallowed immediately after being chewed, no flavor is required. Therefore, the tobacco residue can be used as a powder constituting a molded body. Since tobacco residue, which is normally discarded, can be reused, the environmental burden can be reduced and it is also advantageous in terms of cost. Note that, as described later, the obtained tobacco extract can be used as a flavor component in the coating part.
　前述したように、本実施形態において成型体は噛み砕かれた後にすぐに飲み込まれてしまうため、香味は必要とされない。また、香味成分がたばこ成分である場合、成型体とコーティング部においてニコチン濃度に差がある場合には、使用者がコーティング部を舐め進めて成型体が露出した際に、香味の差異を感じることができ、無煙たばこの使用完了をより容易に認識することができる。これらの観点から、成型体中のニコチン濃度は０．１質量％以下であることが好ましく、０．０５質量％以下であることがより好ましい。また、成型体はニコチンを含まないことが特に好ましい。なお、本実施形態において成型体のニコチン濃度は有機溶媒により抽出されたのち、ＧＣ－ＦＩＤにより測定される。 As mentioned above, in this embodiment, the molded product is swallowed immediately after being chewed, so no flavor is required. In addition, if the flavor component is a tobacco component, and if there is a difference in nicotine concentration between the molded product and the coating, the user may feel a difference in flavor when the molded product is exposed by licking the coating. This makes it easier to recognize when smokeless tobacco has been used. From these viewpoints, the nicotine concentration in the molded body is preferably 0.1% by mass or less, more preferably 0.05% by mass or less. Moreover, it is particularly preferable that the molded product does not contain nicotine. In this embodiment, the nicotine concentration of the molded product is extracted with an organic solvent and then measured by GC-FID.

By having the average particle size of 10 to 300 μm, the molded product can have a suitable surface roughness, and when the user licks the coated part and the molded product is exposed, the surface roughness between the coated part and the coated part is reduced. The completion of use can be more easily recognized due to the difference in height. The average particle diameter is more preferably from 20 to 200 μm, even more preferably from 30 to 100 μm. Note that the average particle diameter is measured using a light scattering method.
　本実施形態において、錠剤硬度計を用いて測定される、前記成型体の杭型プランジャによる圧縮破断強度は２０Ｎ以上、２００Ｎ以下である。該圧縮破断強度が２０Ｎ以上であることにより、口腔用無煙たばこの製造において成型体をコーティング部で容易にコーティングすることができる。また、使用者が口腔用無煙たばこのコーティング部を舐め進めて成型体が露出した際に、該成型体を舐めても容易に崩壊してしまうことがないため、使用完了を容易に認識することができる。一方、前記圧縮破断強度が２００Ｎ以下であることにより、使用者が使用完了を認識して成型体を噛み砕く際に、成型体が適切な噛み心地を有する。前記圧縮破断強度は３０Ｎ以上、１８０Ｎ以下であることが好ましく、４０Ｎ以上、１５０Ｎ以下であることがより好ましい。なお、前記圧縮破断強度は、具体的には後述する方法により測定される値である。 In the present embodiment, the compression rupture strength of the molded body with a pile-shaped plunger is 20 N or more and 200 N or less, as measured using a tablet hardness tester. When the compressive breaking strength is 20 N or more, the molded product can be easily coated with the coating portion in the production of oral smokeless tobacco. Furthermore, when the user licks the coating part of the oral smokeless tobacco and the molded product is exposed, the molded product will not easily disintegrate even if the user licks it, making it easy to recognize when use is complete. Can be done. On the other hand, since the compressive breaking strength is 200 N or less, the molded product has an appropriate chewing feeling when the user recognizes that use is complete and chews the molded product. The compressive breaking strength is preferably 30N or more and 180N or less, more preferably 40N or more and 150N or less. In addition, the said compressive breaking strength is a value specifically measured by the method mentioned later.
　成型体の形状は特に限定されないが、例えば錠剤（タブレット）形状、板状、円筒形状、棒状、球状、葉形状等であることができる。成型体はコーティング部の内部に配置されており、無煙たばこの中心部分に配置されていることが好ましい。また、本実施形態において成型体の表面はコーティング部で全て覆われている。コーティング部中のニコチン濃度が例えば０．２～２質量％である場合、無煙たばこの体積１００質量％に対する成型体の体積割合は１０～６０％が好ましい。成型体の体積割合が前記範囲内であることにより、使用完了をより容易に認識でき、かつ、使用者が成型体をより噛み砕きやすい。粉末を成型して成型体を製造する方法としては、後述する本実施形態に係る口腔用無煙たばこの製造方法と同様に行うことができる。 The shape of the molded product is not particularly limited, but may be, for example, a tablet shape, a plate shape, a cylindrical shape, a rod shape, a spherical shape, a leaf shape, etc. The molded body is disposed inside the coating part, preferably in the center of the smokeless tobacco. Further, in this embodiment, the entire surface of the molded body is covered with a coating portion. When the nicotine concentration in the coating part is, for example, 0.2 to 2% by mass, the volume ratio of the molded product to 100% by mass of the smokeless tobacco is preferably 10 to 60%. When the volume ratio of the molded product is within the above range, completion of use can be more easily recognized, and the user can more easily chew the molded product. The method for producing a molded product by molding the powder can be carried out in the same manner as the method for producing smokeless tobacco for oral use according to the present embodiment, which will be described later.
　（コーティング部）
　本実施形態に係る口腔用無煙たばこにおけるコーティング部は、成型体を外包し、香味成分を含む口腔内で溶解可能なコーティング部であれば特に限定されない。該コーティング部は、例えばたばこ成分等の香味成分と、飴、スクロース、ゼラチン、塩、およびそれらの混合物等の、コーティング基材で構成されることができる。 (Coating part)
The coating part in the oral smokeless tobacco according to the present embodiment is not particularly limited as long as it is a coating part that encases the molded product and contains a flavor component and can be dissolved in the oral cavity. The coating can be comprised of a flavor component, such as a tobacco component, and a coating substrate, such as candy, sucrose, gelatin, salt, and mixtures thereof.
　本実施形態では、特に前記コーティング部が、たばこ原料から抽出された、香味成分を含むたばこ抽出液を含むことが好ましい。前述したように、成型体を構成する粉末として、たばこ原料から香味成分を含むたばこ抽出液を抽出した後のたばこ残渣を使用する場合、該たばこ抽出液をコーティング部に含ませることで、コーティング部に香味成分を容易に付与することができ、またコスト面でも有利である。すなわち、本実施形態では、成型体を構成する粉末が、たばこ原料から香味成分を含むたばこ抽出液を抽出した後のたばこ残渣であり、かつ、前記コーティング部が該抽出により得られる該たばこ抽出液を含むことが特に好ましい。なお、コーティング部に含まれるたばこ抽出液は、成型体を構成するたばこ残渣の調製時に得られるたばこ抽出液とは異なるたばこ抽出液であってもよいが、同じたばこ抽出液であることが好ましい。 In this embodiment, it is particularly preferable that the coating portion contains a tobacco extract containing flavor components extracted from tobacco raw materials. As mentioned above, when using tobacco residue after extracting tobacco extract containing flavor components from tobacco raw materials as the powder constituting the molded product, by incorporating the tobacco extract into the coating part, the coating part Flavor components can be easily added to the product, and it is also advantageous in terms of cost. That is, in the present embodiment, the powder constituting the molded body is the tobacco residue after extracting the tobacco extract containing flavor components from the tobacco raw material, and the coating portion is the tobacco extract obtained by the extraction.

Moreover, it is particularly preferable that the molded product does not contain nicotine.
　錠剤硬度計を用いて測定される、本工程により得られる成型体の杭型プランジャによる圧縮破断強度は２０Ｎ以上、２００Ｎ以下である。該圧縮破断強度が２０Ｎ以上であることにより、後述するコーティング部形成工程において成型体をコーティング部の材料で容易にコーティングすることができる。また、使用者が口腔用無煙たばこのコーティング部を舐め進めて成型体が露出した際に、該成型体を舐めても容易に崩壊してしまうことない。一方、前記圧縮破断強度が２００Ｎ以下であることにより、使用者が使用完了を認識して成型体を噛み砕く際に、成型体が適切な噛み心地を有する。前記圧縮破断強度は、３０Ｎ以上、１８０Ｎ以下であることが好ましく、４０Ｎ以上、１５０Ｎ以下であることがより好ましい。なお、前記圧縮破断強度は、具体的には後述する方法により測定される値である。 The compression rupture strength of the molded product obtained by this step with a pile plunger, as measured using a tablet hardness meter, is 20N or more and 200N or less. When the compressive breaking strength is 20 N or more, the molded body can be easily coated with the material of the coating portion in the coating portion forming step described below. Furthermore, when the user licks the coating portion of the oral smokeless tobacco to expose the molded product, the molded product will not easily disintegrate even if the user licks the molded product. On the other hand, since the compressive breaking strength is 200 N or less, the molded product has an appropriate chewing feeling when the user recognizes that use is complete and chews the molded product. The compressive breaking strength is preferably 30N or more and 180N or less, more preferably 40N or more and 150N or less. In addition, the said compressive breaking strength is a value specifically measured by the method mentioned later.

　［比較例１］
　セルロースパウダー成型体の成型時の圧縮圧力を変更した以外は、実施例１と同様に無煙たばこを製造し、評価した。結果を表１に示す。 [Comparative example 1]
Smokeless tobacco was produced and evaluated in the same manner as in Example 1, except that the compression pressure during molding of the cellulose powder molded body was changed. The results are shown in Table 1.
　［比較例２］
　セルロースパウダー成型体を風乾する代わりに、２１０℃で５分間加熱した以外は、実施例２と同様に無煙たばこを製造し、評価した。結果を表１に示す。なお、成型体の圧縮破断強度の測定において、２００Ｎでも成型体が破断しなかったため、成型体の圧縮破断強度は２００Ｎを超えると判断した。 [Comparative example 2]
Smokeless tobacco was produced and evaluated in the same manner as in Example 2, except that the cellulose powder molded body was heated at 210° C. for 5 minutes instead of being air-dried. The results are shown in Table 1. In addition, in the measurement of the compressive breaking strength of the molded article, the molded article did not break even at 200N, so it was determined that the compressive breaking strength of the molded article exceeded 200N.
　表１に示されるように、成型体の圧縮破断強度が２０Ｎ以上、２００Ｎ以下である実施例１～５では、使用完了を容易に識別することができ、また使用完了時の噛み心地が良好であった。実施例６では使用完了の識別容易性、使用完了時の噛み心地の評価はなされていないが、成型体の圧縮破断強度が２０～２００Ｎの範囲内であるため、実施例１～５と同様の評価結果が得られることが予測できる。一方、成型体の圧縮破断強度が２０Ｎ未満である比較例１では、成型体が唾液により容易に崩壊したため、使用完了を容易に識別することができなかった。また、成型体の圧縮破断強度が２００Ｎを超える比較例２では、使用完了時の噛み心地の評価が低かった。 As shown in Table 1, in Examples 1 to 5, in which the compressive breaking strength of the molded product was 20N or more and 200N or less, it was possible to easily identify when the use was completed, and the chewing feeling was good when the use was completed. there were. In Example 6, the ease of identifying when the use is completed and the chewing comfort at the time of the use are not evaluated, but since the compressive breaking strength of the molded product is within the range of 20 to 200N, the results are the same as in Examples 1 to 5. It is possible to predict that evaluation results will be obtained. On the other hand, in Comparative Example 1 in which the compressive breaking strength of the molded product was less than 20 N, the molded product was easily disintegrated by saliva, so it was not possible to easily identify when the product had been used. Furthermore, in Comparative Example 2 in which the compressive breaking strength of the molded product exceeded 200 N, the evaluation of chewing comfort at the end of use was low.
