Description

本発明は、オーラルたばこ製品に関する。   The present invention relates to oral tobacco products.

スヌースのようなオーラルたばこ製品は、不織布のような材料により形成された包装材にたばこ原料が収納されてなるものであり、使用者はこれを口腔内に入れて使用する。
オーラルたばこ製品は、その使用態様から、たばこ原料から使用者の口腔内にたばこ原料に含まれる望ましくない成分が染み出ることがある。このことについて、例えば、特許文献1〜3には、たばこ原料に含まれるニトロソアミンをオーラルたばこ製品の製造時に低減するための技術が記載されている。
An oral tobacco product such as snus is obtained by storing a tobacco raw material in a packaging material formed of a material such as a nonwoven fabric, and a user puts it in the oral cavity and uses it.
The oral tobacco product may bleed out undesirable components contained in the tobacco material from the tobacco material into the user's oral cavity due to the manner of use. In this regard, for example, Patent Documents 1 to 3 describe techniques for reducing nitrosamines contained in tobacco raw materials during the production of oral tobacco products.

上記特許文献1には、たばこ原料に存在するニトロソアミンを低減させるために、たばこ葉にマイクロ波を照射する工程を含む処理を経ることで、その後たばこ葉中でニトロソアミンの形成を阻害する方法が記載されている。特許文献2ではニトロソアミンの量を減少させるために、収穫したたばこ葉を圧搾したり、蒸気処理を行うことで処理することを開示している。特許文献3では、空気乾燥させて黄変したたばこ葉を自然乾燥工程と制御乾燥工程により乾燥させ、たばこ原料中の亜硝酸態窒素やニトロソアミンを減少させることを開示している。
上記のような技術とは別に、特許文献4には、無煙たばこ組成物に関する技術が記載されており、当該組成物に含有させるものとして着色料を挙げている。
Patent Document 1 describes a method for inhibiting the formation of nitrosamines in tobacco leaves by performing a treatment including a step of irradiating the tobacco leaves with microwaves in order to reduce nitrosamines present in tobacco raw materials. Has been. Patent Document 2 discloses that the harvested tobacco leaf is squeezed or steamed to reduce the amount of nitrosamine. Patent Document 3 discloses that tobacco leaves that have been yellowed by air drying are dried by a natural drying process and a controlled drying process to reduce nitrite nitrogen and nitrosamines in the tobacco raw material.
Apart from the above-described technology, Patent Document 4 describes a technology related to a smokeless tobacco composition, and mentions a coloring agent as a component contained in the composition.

特許第4108754号公報Japanese Patent No. 4108754 特許第3996958号公報Japanese Patent No. 3996958 特許第3922985号公報Japanese Patent No. 3922985 特表2009−508523号公報Special table 2009-508523

上記特許文献1〜3に記載の方法は、緑色のたばこ葉はヒトの消費に適さないという事情があることから、いずれも収穫したたばこ葉を、緑色がなくなってから(大部分が黄色になってから)、乾燥処理(マイクロ波や制御乾燥)を実施するというものである。特許文献1〜3に記載の方法では、収穫したたばこ葉を処理するタイミングは、少なくとも緑色である状態ではなくなってからということを開示している。
しかし本発明者は、これをオーラルたばこ製品の原料として用いた場合、その処理条件によっては、処理後も緑色であり、口腔内に出る抽出液の色が淡いことを発見した。
特許文献1等に記載の方法のように、黄色に変色したたばこ葉を乾燥処理したたばこ原料をオーラルたばこ製品に使用した場合には、口腔内に出る抽出液の色が濃くなることが想定される。
このような濃い色の抽出液が生じるような場合、使用者に好ましくない印象を与える可能性がある。
一方、特許文献4では、上記のように無煙たばこ組成物に含ませる材料として着色料を挙げている。このような技術によれば、無煙たばこ組成物を着色することはできるものの、その作用は含有されている着色剤に起因するものである。
In the methods described in Patent Documents 1 to 3, since green tobacco leaves are not suitable for human consumption, all harvested tobacco leaves are used after the green color disappears (mostly yellow). And then drying treatment (microwave or controlled drying). In the methods described in Patent Documents 1 to 3, it is disclosed that the timing of processing the harvested tobacco leaves is at least not in a green state.
However, the present inventor has discovered that, when this is used as a raw material for oral tobacco products, depending on the processing conditions, it is still green after the processing, and the color of the extract that comes into the oral cavity is light.
As in the method described in Patent Document 1, etc., when a tobacco raw material obtained by drying a tobacco leaf that has turned yellow is used for an oral tobacco product, it is assumed that the color of the extract that comes out in the oral cavity becomes darker. The
When such a dark extract liquid is generated, there is a possibility that an unpleasant impression is given to the user.
On the other hand, in patent document 4, the coloring agent is mentioned as a material included in a smokeless tobacco composition as mentioned above. According to such a technique, although a smokeless tobacco composition can be colored, the effect | action originates in the coloring agent contained.

このようなことから、本発明では、着色剤を用いることなくたばこ原料の緑色が維持されているとともに、水を溶媒として抽出を行った場合に抽出液の色が淡いオーラルたばこ製品を提供することを課題とする。   Therefore, the present invention provides an oral tobacco product in which the green color of the tobacco raw material is maintained without using a colorant and the color of the extract is light when extraction is performed using water as a solvent. Is an issue.

本発明者が鋭意検討した結果、特定の処理工程を経て得られるたばこ原料を用いたオーラルたばこ製品が、緑色を呈し、かつ、水を抽出溶媒として用いた抽出液の色が淡くなることで、上記課題を解決できることがわかり、本発明に到達した。   As a result of intensive studies by the present inventors, oral tobacco products using tobacco raw materials obtained through a specific treatment step exhibit a green color, and the color of the extract using water as an extraction solvent is light, It has been found that the above problems can be solved, and the present invention has been achieved.

<たばこ原料>
本発明のオーラルたばこ製品に用いられるたばこ原料となるたばこ種は、特に限定されるものではなく、例えばニコチアナ属であり、ニコチアナタバカムの黄色種・バーレー種、ニコチアナルスチカのブラジリア種などを挙げることができる。
たばこ原料として用いられるたばこ葉は、先行技術文献に記載の発明とは異なり、その色が黄変する前、すなわち大部分が緑色である時に以下で示す処理工程に供される。
ここで、「黄変する」とは、L*a*b*法で表現したa*値について、収穫葉の面積の大部分、例えば60%以上、例えば90%以上が1.0より大きい値になるまで変色したものをいう。たばこ葉はその収穫後に、たばこ葉に存在する(緑色)色素が減少することにより、黄変していく。なお、たばこ葉の収穫後のa*値は、通常−9〜−1.5程度である。
<Tobacco ingredients>
Tobacco species that are used as a raw material for tobacco used in the oral tobacco product of the present invention are not particularly limited. be able to.
Unlike the invention described in the prior art document, the tobacco leaf used as a tobacco raw material is subjected to the following processing steps before its color is yellowed, that is, when most of the color is green.
Here, “yellowing” means a value of a large portion of the harvested leaf area, for example, 60% or more, for example 90% or more, greater than 1.0 with respect to the a * value expressed by the L * a * b * method The one that has changed color until. Tobacco leaves turn yellow after the harvest due to a decrease in the (green) pigment present in the tobacco leaves. The a * value after harvesting tobacco leaves is usually about -9 to -1.5.

本発明のオーラルたばこ製品で用いられるたばこ原料は、L*a*b*法で表現したa*値(以下、緑色度ともいう)が、1.0以下であるとともに、当該たばこ原料について、水を抽出溶媒として用いた場合の抽出液の、420nm波長の吸光度が1.0以下である。
本発明のオーラルたばこ製品で用いられるたばこ原料は、上記を満たす限り特に限定されるものでなく、収穫後、たばこ葉から中骨を取り除いたものを処理工程に供してもよい。また、収穫後、たばこ葉を圧搾等により水分を除去してから処理工程に供してもよい。また、収穫後、たばこ葉を冷蔵もしくは冷凍保存した後に処理工程に供してもよい。
L*a*b*法におけるa*値は、その値が小さいほど緑色が強くなる。緑色は、通常のシガレットに用いられる際の収穫時期よりも早期に収穫することによって強くすることが出来る。この範囲の下限としては、−20以上であることが、たばこ原料として緑色であることを担保する観点から適当である。たばこ原料の緑色を強くしたい場合には、緑色度(a*値)は−2以下であることが適当である。
たばこ原料のa*値の測定は、水分3〜5重量%まで乾燥したたばこ原料を、粉砕機を用いて1−2mmメッシュの大きさに粉砕し、分光測色計を用いて粉砕したサンプルの色を測定することで行うことができる。なお、色の定義は、国際照明委員会(Commission International de l’Eclairage: CIE)およびJISにて採用されているL*a*b*表色系にて表現するものである。
測色操作は、サンプル粉体をガラス容器に層厚1cm投入し、容器底部から標準光(測色用標準イルミナントD65, CIE, ISOの基準光)を当て、反射光を測定(反射色測定/正反射光除去方式(SCE))することで数値化できる。
また、このa*値は、後述するたばこ原料の処理工程において、加熱処理の温度と時間を変更することで調整することができる。
具体的には、a*値の増加を抑制するには加熱処理の温度を低くしたり、その時間を短くしたりすることで可能である。
The tobacco raw material used in the oral tobacco product of the present invention has an a * value (hereinafter also referred to as greenness) expressed by the L * a * b * method of 1.0 or less, and the tobacco raw material When the extract is used as an extraction solvent, the absorbance at a wavelength of 420 nm is 1.0 or less.
The tobacco raw material used in the oral tobacco product of the present invention is not particularly limited as long as the above is satisfied, and a product obtained by removing the middle bone from the tobacco leaf after harvest may be subjected to a treatment step. Further, after harvesting, the tobacco leaf may be subjected to a treatment step after removing moisture by pressing or the like. Further, after harvesting, the tobacco leaf may be refrigerated or frozen and then subjected to a treatment step.
As the a * value in the L * a * b * method is smaller, green becomes stronger. The green color can be strengthened by harvesting earlier than the harvesting time used for normal cigarettes. The lower limit of this range is suitably −20 or more from the viewpoint of ensuring that the tobacco raw material is green. In order to increase the green color of the tobacco material, the greenness (a * value) is suitably −2 or less.
The a * value of the tobacco material was measured by pulverizing the tobacco material dried to a moisture content of 3 to 5% by weight to a size of 1-2 mm using a pulverizer and using a spectrophotometer. This can be done by measuring the color. The color definition is expressed in the L * a * b * color system adopted by the International Commission on Illumination (Commission International de l'Eclairage: CIE) and JIS.
For colorimetric operation, sample powder is placed in a glass container with a thickness of 1 cm, standard light (standard light for colorimetry D65, CIE, ISO standard light) is applied from the bottom of the container, and reflected light is measured (reflected color measurement / It can be quantified by using the regular reflection light removal method (SCE).
This a * value can be adjusted by changing the temperature and time of the heat treatment in the tobacco raw material processing step described later.
Specifically, the increase in the a * value can be suppressed by lowering the temperature of the heat treatment or shortening the time.

処理前のたばこ葉のa*値の測定は、以下のようにして行われる。
たばこ葉の表面の20カ所を分光測色計(KONICA MINOLTA/CM3500d, Konica MinoltaHoldings, Inc)を用いて色を測定する。色の定義は、上記のたばこ原料の測色と同じく、L*a*b*表色系にて表現する。たばこ葉表面の20カ所とは、例えば図6の★に示すようにたばこ葉の中央部と外周部について均等に選択する。
測色操作は、標準光(測色用標準イルミナントD65, CIE, ISOの基準光)を当て、反射光を測定(反射色測定/正反射光除去方式(SCE)) にて行って数値化する。上記条件でたばこ葉を測定した時のa*値が小さいほど緑色であると言える。
Measurement of the a * value of the tobacco leaf before treatment is performed as follows.
The color of the surface of the tobacco leaf is measured using a spectrocolorimeter (KONICA MINOLTA / CM3500d, Konica Minolta Holdings, Inc.). The definition of the color is expressed in the L * a * b * color system similar to the above colorimetric measurement of tobacco materials. The 20 places on the surface of the tobacco leaf are selected equally for the central portion and the outer peripheral portion of the tobacco leaf, for example, as shown by * in FIG.
The colorimetric operation is performed by applying standard light (standard light for colorimetry D65, CIE, and ISO standard light) and measuring reflected light (reflected color measurement / regular reflected light removal method (SCE)) to digitize the measurement. . The smaller the a * value when measuring tobacco leaves under the above conditions, the greener the color.

また、本発明のたばこ原料は、水を抽出溶媒として用いた場合の抽出液の色について、420nm波長の吸光度(「ABS420nm」とも表記する)が1.0以下である。
また、上記吸光度は、たばこ原料について上記処理が行われた場合、通常、0.2以上になる。
この抽出は、以下のような手順で行って得られるものである。
水分を5重量%以下にまで低減させ、粉砕したたばこ原料1重量部を秤量し、22℃の水25重量部に加えて10分程度振盪抽出を行う。その後同温度で20分程度静置し、抽出液を0.20μmのメンブレンフィルターでろ過する。ろ過後の溶液を水で二倍希釈し、分光吸光光度計を用い、420nm波長の吸光度を測定する。
なお、本発明において、上記条件の吸光度の数値を「褐変度」ともいい、この数値が大きいほど抽出液の褐色度が高いと定義する。また、本発明において褐色と茶色は同義である。
この褐変度については、後述するたばこ原料の処理工程において、加熱処理の温度と時間を変更することで調整することができる。
具体的には、褐変度の増加を抑制するには加熱処理の温度を高くしたり、その時間を長くしたりすることで可能である。
The tobacco raw material of the present invention has an absorbance at a wavelength of 420 nm (also referred to as “ABS 420 nm”) of 1.0 or less with respect to the color of the extract when water is used as an extraction solvent.
Moreover, the said light absorbency will be 0.2 or more normally, when the said process is performed about the tobacco raw material.
This extraction is obtained by the following procedure.
Moisture is reduced to 5% by weight or less, 1 part by weight of the pulverized tobacco raw material is weighed, and added to 25 parts by weight of water at 22 ° C., followed by shaking extraction for about 10 minutes. Thereafter, the mixture is allowed to stand at the same temperature for about 20 minutes, and the extract is filtered through a 0.20 μm membrane filter. The filtered solution is diluted twice with water, and the absorbance at a wavelength of 420 nm is measured using a spectrophotometer.
In the present invention, the numerical value of absorbance under the above conditions is also referred to as “browning degree”, and the larger the numerical value, the higher the brownness of the extract is defined. In the present invention, brown and brown are synonymous.
About this browning degree, in the process of the tobacco raw material mentioned later, it can adjust by changing the temperature and time of heat processing.
Specifically, in order to suppress the increase in browning degree, it is possible to increase the temperature of the heat treatment or lengthen the time.

Specifically, after harvesting, the tobacco raw material obtained through the step of drying after yellowing (for example, irradiation with microwaves) usually has a colorimetric value (ABS 420 nm) of the extract of about 1.4 or more. become.
On the other hand, in the present invention, as described above, the tobacco leaves are subjected to a treatment step before yellowing.

本発明において、「褐変関与酵素を失活させる条件」とは、下記で説明する手順を用いて測定される酵素活性(PPO(Polyphenol Oxidase)活性)値が0.02U以下になる条件をいう。
酵素活性値は、分光吸光光度計のセルに、試料から酵素タンパク質を抽出した溶液と、リン酸カリウム緩衝液(pH6.0)を加えて混合し、これに基質として10mMピロカテコール溶液を加え、40℃におけるリファレンスに対する420nm波長の吸光度の増加を測定することで得ることができる。リファレンスとしては、酵素タンパク質液のかわりに脱イオン水を混合した液を挙げることができる。
リファレンスの吸光度増加分を差し引き、試料の吸光度(ΔABS)を一分間に0.01上昇させる酵素量を1Uと定義する。
In the present invention, “conditions for inactivating the enzyme responsible for browning” refers to conditions under which the enzyme activity (PPO (Polyphenol Oxidase) activity) value measured using the procedure described below is 0.02 U or less.
The enzyme activity value was measured by adding a solution obtained by extracting enzyme protein from a sample to a cell of a spectrophotometric photometer and adding a potassium phosphate buffer (pH 6.0), and adding a 10 mM pyrocatechol solution as a substrate thereto. It can be obtained by measuring the increase in absorbance at 420 nm relative to the reference at 40 ° C. As a reference, a liquid in which deionized water is mixed instead of the enzyme protein liquid can be mentioned.
The amount of enzyme that increases the absorbance (ΔABS) of the sample by 0.01 by subtracting the increase in absorbance of the reference is defined as 1 U.

上記のたばこ原料の処理工程において、「褐変関与酵素を失活させる条件」とは、たばこ葉の酵素活性(PPO活性)値が0.02U以下になる条件のことであり、このような条件としては、例えば、80〜100℃での加熱を挙げることができる。この時の加熱時間は、通常、40分以内であり、加熱温度に応じてa*値が大きく上昇しない範囲で設定できる。
このような加熱を経ることで、たばこ葉の褐変関与酵素が失活し、たばこ原料が変色することなく緑色を保ち、かつ、その抽出液の色を淡い色(ABS420nmを小さく)することができる。
この加熱は、85℃以上、10分以内の態様がより好ましく、90℃以上、かつ5分以内で行うことが、たばこ原料が変色することなく緑色を保ち、かつ、その抽出液の色を淡い色に保つ観点からさらに好ましい。
なお、上記の温度については、加熱装置の設定温度ではなく、加熱されるたばこ葉自体の温度を示す。
In the above tobacco raw material treatment process, the “conditions for inactivating the enzyme responsible for browning” are conditions where the tobacco leaf enzyme activity (PPO activity) value is 0.02 U or less.

For example, steaming under steam pressure.
When heating is performed by applying hot air, for example, a method in which an air flow of 90 ° C. or higher and 90% relative humidity is aerated within 10 minutes can be mentioned.
Examples of the method of immersing in warm water include a method of immersing in boiling warm water and boiling at atmospheric pressure.

<実験例1−1>葉たばこの乾燥法の違い(慣行乾燥とマイクロ波乾燥)が及ぼす影響について
3種類のたばこ葉について、慣行乾燥(Conventional drying)とマイクロ波乾燥(Microwave drying)を実施した時の、乾燥葉の外観(色彩)を測定する実験を行った。3種類の原料はそれぞれ、BLY: バーレー種, FCV:黄色種, Rustica:ニコチアナ・ルスチカを用いた。
外観の色彩については、以下の手順により測定した。
水分3〜5%まで乾燥したたばこ原料を、粉砕機(MiniBlender, Melitta Japan Ltd., Tokyo, Japan)を用いて1−2mmメッシュの大きさに粉砕し、分光測色計(KONICA MINOLTA/CM3500d, Konica MinoltaHoldings, Inc)を用いて粉砕したサンプルの色を測定した。色の定義は、国際照明委員会(Commission International de l'Eclairage: CIE)およびJISにて採用されているL*a*b*表色系にて表現した。
測色操作は、サンプル粉体をガラス容器に層厚1cm投入し、容器底部から標準光(測色用標準イルミナントD65, CIE, ISOの基準光)を当て、反射光を測定(反射色測定/正反射光除去方式(SCE)) にて行って数値化した。
結果を図1(a)に示す。
図1(a)の縦軸(a*)は、L*a*b*法で表現した分光測色計のデータであり、a*値が小さいほど緑色である。測色値を比較すると、3種類いずれの原料においても、慣行乾燥と比較し、マイクロ波乾燥した乾燥葉は緑色度が高かった。
<Experimental Example 1-1> Effects of Differences in Drying Methods of Leaf Tobacco (Conventional Drying and Microwave Drying) When performing conventional drying and microwave drying on three types of tobacco leaves An experiment for measuring the appearance (color) of dried leaves was conducted. Three types of raw materials were BLY: Burley, FCV: Yellow, and Rustica: Nicotiana Rustica.
The appearance color was measured by the following procedure.
Tobacco raw material dried to a moisture content of 3 to 5% is pulverized to a size of 1-2 mm using a pulverizer (MiniBlender, Melitta Japan Ltd., Tokyo, Japan), and a spectrocolorimeter (KONICA MINOLTA / CM3500d, The color of the ground sample was measured using Konica Minolta Holdings, Inc). The color definition was expressed in the L * a * b * color system adopted by the International Commission on Illumination (Commission International de l'Eclairage: CIE) and JIS.
For colorimetric operation, sample powder is placed in a glass container with a thickness of 1 cm, standard light (standard light for colorimetry D65, CIE, ISO standard light) is applied from the bottom of the container, and reflected light is measured (reflected color measurement / It was converted into a numerical value by the regular reflection light removal method (SCE).
The results are shown in FIG.
The vertical axis (a *) in FIG. 1A is spectrocolorimeter data expressed by the L * a * b * method. The smaller the a * value, the greener the color. When the colorimetric values were compared, the dryness of the microwave-dried leaves was higher in green compared to the conventional drying in all three types of raw materials.

なお、本発明では慣行乾燥として、たばこ葉種類により、以下の乾燥方法を用いる。以下の慣行乾燥は、全て常圧下で行った。
黄色種の場合、収穫したたばこ葉はFlue-curingと呼ばれる工程を経て乾燥される。一般に、収穫された後、30〜50℃の湿度管理された乾燥室で3日間かけてキュアし、その後約70℃で2日間乾燥させてたばこ原料水分を5重量%以下まで下げる。
バーレー種の場合、収穫したたばこ葉はAir-curingと呼ばれる工程を経て乾燥される。一般に、収穫された後、外気温〜35℃の湿度管理された環境下で30〜35日間かけて水分を15重量%以下まで乾燥する。
ニコチアナ・ルスチカの場合、収穫したたばこ葉はSun-air-cuingと呼ばれる工程を経て乾燥される。一般に収穫された後、数日から一週間程度、外気温で天日干し乾燥する。
In the present invention, as conventional drying, the following drying method is used depending on the type of tobacco leaf. The following conventional drying was performed under normal pressure.
In the case of yellow varieties, the harvested tobacco leaves are dried through a process called Flue-curing. Generally, after being harvested, it is cured for 3 days in a humidity-controlled drying room at 30 to 50 ° C., and then dried at about 70 ° C. for 2 days to lower the moisture content of the tobacco to 5% by weight or less.
In the case of Burley, harvested tobacco leaves are dried through a process called Air-curing. In general, after being harvested, the moisture is dried to 15% by weight or less over a period of 30 to 35 days in a humidity-controlled environment of outside temperature to 35 ° C.
In the case of Nicotiana Rustica, harvested tobacco leaves are dried through a process called Sun-air-cuing. In general, after being harvested, it is sun-dried at ambient temperature for several days to a week.

<実験例1−2>
実験例1−1と同じく3種類の原料について、その抽出液の色合いを測定した。結果を図1(b)に示す。抽出液の色は、前述した通り、420nm波長の吸光度で表現している。吸光度が高いほど(Y軸の値が大きいほど)褐色である。
たばこ原料の抽出液の褐変度は、以下の方法にて測定した。水分5%以下まで乾燥した原料(たばこ葉)を0.4g秤量し、水10mLを加えて10分間22℃で振盪抽出する。振盪後、22℃で20分間静置し、抽出液を0.20μm孔径メンブレンフィルター(Whatman PVDF membrane, GE Healthcare UK Ltd., Buckinghamshire, UK)でろ過した。この溶液を水で二倍希釈し、分光吸光光度計を用いて420nm波長の吸光度を測定した。
図1(b)に示されるように、3種類いずれの原料に関しても、慣行乾燥によるたばこ原料と比較し、マイクロ波乾燥したたばこ原料の方が抽出液の褐変度が小さかった。
すなわち、マイクロ波乾燥したたばこ原料を原料としてオーラルたばこ製品に用いた場合、慣行乾燥を経たたばこ原料を原料として用いた場合に比べて口腔内の唾液の色が淡くなり、また、使用後にオーラルたばこ製品の包装材である不織布が茶色くならないことが期待できる。
<Experimental example 1-2>
Similar to Experimental Example 1-1, the color of the extract was measured for three types of raw materials. The results are shown in FIG. As described above, the color of the extract is expressed by absorbance at a wavelength of 420 nm. The higher the absorbance (the larger the Y-axis value), the browner.
The browning degree of the tobacco raw material extract was measured by the following method. 0.4 g of raw material (tobacco leaves) dried to a moisture content of 5% or less is weighed, 10 mL of water is added, and the mixture is extracted by shaking at 22 ° C. for 10 minutes. After shaking, the mixture was allowed to stand at 22 ° C. for 20 minutes, and the extract was filtered through a 0.20 μm pore size membrane filter (Whatman PVDF membrane, GE Healthcare UK Ltd., Buckinghamshire, UK). This solution was diluted twice with water, and absorbance at a wavelength of 420 nm was measured using a spectrophotometer.
As shown in FIG. 1 (b), for any of the three types of raw materials, the browning degree of the extract was lower in the microwave-dried tobacco raw material than in the tobacco raw material by conventional drying.
In other words, when microwave-dried tobacco materials are used as raw materials for oral tobacco products, the saliva color in the oral cavity becomes lighter than when tobacco materials that have undergone conventional drying are used as raw materials. It can be expected that the non-woven fabric that is the product packaging material will not turn brown.

<実験例2>加熱温度ごとの各種効果について
たばこ葉について加熱処理を行い、その時の外観(色彩)と抽出液の外観(色彩)を測定した。
たばこ種としてバーレー種、凍結乾燥済のものを使用した。
加熱処理:40〜100℃において10分間加熱した。原料としたたばこ葉は真空パックに梱包し、湯浴にて加熱処理した。結果を図2(a)及び(b)に示す。これらの結果(たばこ葉(バーレー種を凍結乾燥した葉)を各温度で10分間加熱した場合の測色値)から、80℃以上で加熱した場合、緑色度が低下していく(図2(a))。一方で、85℃以上で加熱した場合、加熱処理されたたばこ原料の抽出液の色が淡くなる(褐変度が低くなる)ことがわかった(図2(b))。
<Experimental example 2> About various effects for every heating temperature The tobacco leaf was heat-processed and the external appearance (color) and the external appearance (color) of the extract were measured.
Burley seeds and lyophilized ones were used as tobacco seeds.
Heat treatment: Heated at 40-100 ° C. for 10 minutes. The tobacco leaf as a raw material was packed in a vacuum pack and heat-treated in a hot water bath. The results are shown in FIGS. 2 (a) and (b). From these results (tobacco leaves (colorimetric values when freeze-dried burley seeds are heated for 10 minutes) at each temperature), the greenness decreases when heated at 80 ° C. or higher (FIG. 2 ( a)). On the other hand, when it heated at 85 degreeC or more, it turned out that the color of the extract of the tobacco raw material heat-processed becomes light (a browning degree becomes low) (FIG.2 (b)).

<実験例3>加熱時間ごとの各種効果について
たばこ葉について加熱処理を行い、その時の外観(色彩)と抽出液の外観(色彩)を実験例1と同様の手順により測定した。
たばこ葉はバーレー種、凍結乾燥済のものを使用した。
加熱処理:80, 90, 100℃の3水準、加熱時間は1〜40分間、加熱方式は実験例2と同様にした。
図3(a)は、たばこ葉(バーレー凍結乾燥葉)を80℃、90℃、100℃の3条件で、加熱時間を変更した場合の、処理原料の測色値を示している。いずれの温度でも、加熱時間の経過に伴い、緑色度が低下したことが分かる。加熱温度が高くなるほど、短時間で退色した。
図3(b)は、たばこ葉(バーレー凍結乾燥葉)を80℃、90℃、100℃の3条件で、加熱時間を変更した場合の、処理原料の抽出液の褐変度を示している。加熱時間の経過に伴い、処理原料の褐変度が抑えられることが分かった。
これらの結果から、80℃で30分加熱した時(A)と、90℃で5分加熱したとき(B)と、100℃で2分加熱したとき(C)で、抽出液の褐変度はほぼ同じであるが(図3(b))、緑色度は全く異なることが分かった(図3(a))。
<Experimental Example 3> Various Effects for Each Heating Time Tobacco leaves were subjected to heat treatment, and the appearance (color) and the appearance of the extract (color) at that time were measured by the same procedure as in Experimental Example 1.
Tobacco leaves used were Burley seeds and lyophilized ones.
Heat treatment: Three levels of 80, 90, and 100 ° C., heating time of 1 to 40 minutes, and heating method were the same as in Experimental Example 2.
FIG. 3A shows the colorimetric values of the processing raw materials when the heating time is changed under the three conditions of 80 ° C., 90 ° C., and 100 ° C. for tobacco leaves (Burley freeze-dried leaves). It can be seen that at any temperature, the greenness decreased with the elapse of the heating time. The higher the heating temperature, the faster the color faded.
FIG.3 (b) has shown the browning degree of the extract of a processing raw material at the time of changing a heating time on 3 conditions, 80 degreeC, 90 degreeC, and 100 degreeC of a tobacco leaf (Burley freeze-dried leaf). It turned out that the browning degree of a processing raw material is suppressed with progress of heating time.
From these results, the browning degree of the extract is as follows: when heated at 80 ° C. for 30 minutes (A), when heated at 90 ° C. for 5 minutes (B), and heated at 100 ° C. for 2 minutes (C). Although it was almost the same (FIG. 3B), it was found that the greenness was completely different (FIG. 3A).

<実験例4>加熱タイミングについて
加熱処理を、たばこ葉の乾燥前、乾燥中、乾燥後の、各タイミングで実施した場合の、たばこ原料の外観(図4(a))とたばこ原料抽出液の外観(図4(b))について調べた。
たばこ葉としてはバーレー種、実施例における処理方法については以下のように行った。
・乾燥前加熱: 収穫葉を気流加熱(85℃、10分)した後、凍結乾燥により乾燥
・乾燥中加熱: 収穫葉をマイクロ波加熱により加熱乾燥
・乾燥後加熱: 収穫葉を凍結乾燥後、100℃で3分加熱
・対照:バーレー種慣行乾燥原料(Air-cured Leaf)
図4(a)及び4(b)に示される結果より、加熱処理を乾燥前、乾燥中、乾燥後のどのタイミングに実施したとしても、一定の条件を満たす限り、たばこ原料の緑色度は担保でき、たばこ原料の抽出液の着色(色が濃くなること)も防ぐことができることが分かった。一定の条件とは、たばこ葉が変色する前に加熱処理および乾燥を終え、また、実験例3と同様に、加熱処理は高温短時間での処理である。
<Experimental Example 4> Heating Timing Appearance of tobacco raw material (FIG. 4 (a)) and tobacco raw material extract when heat treatment is performed at each timing before, during and after drying of tobacco leaves. The appearance (FIG. 4B) was examined.
The tobacco leaves were Burley species, and the treatment methods in the examples were as follows.
-Heating before drying: Heating the harvested leaves with airflow (85 ° C, 10 minutes), then drying by freeze-drying, heating during drying: Heating the harvested leaves by microwave heating, heating after drying: After freeze-drying the harvested leaves, Heat at 100 ° C for 3 min. Control: Burley seed customary dry material (Air-cured Leaf)
From the results shown in FIGS. 4 (a) and 4 (b), the greenness of the tobacco material is guaranteed as long as certain conditions are satisfied, regardless of the timing of the heat treatment before, during, or after drying. It was found that coloring of the tobacco liquid extract (darkening of the color) can also be prevented. The certain condition is that the heat treatment and drying are finished before the tobacco leaf is discolored, and the heat treatment is a treatment at a high temperature in a short time as in Experimental Example 3.

<実験例5>
本発明のたばこ原料(a*値:−11.0、抽出液の420nm波長の吸光度:0.3)と、それ以外のたばこ原料(通常オーラルたばこ製品に用いられるたばこ原料であり、a*値:8.31、420nm波長の吸光度:1.4)を混合した場合に得られるa*値と、吸光度(420nm)の関係を測定した。
図5の(a)及び(b)にその結果を示す。図中の横軸は、本発明のたばこ原料の割合(重量%)を示す。
本発明のたばこ原料と、それ以外の通常のたばこ原料とを混合する場合には、概ね40重量%以上であると、望ましいa*値や吸光度(420nm)を得ることができる。
<Experimental example 5>
Tobacco material of the present invention (a * value: −11.0, absorbance at 420 nm wavelength of extract: 0.3) and other tobacco materials (cigarette materials usually used in oral tobacco products, a * value : 8.31, Absorbance at 420 nm wavelength: 1.4) and the relationship between a * value obtained and absorbance (420 nm) was measured.
The results are shown in (a) and (b) of FIG. The horizontal axis in the figure indicates the ratio (% by weight) of the tobacco raw material of the present invention.
When the tobacco raw material of the present invention is mixed with other normal tobacco raw materials, a desirable a * value and absorbance (420 nm) can be obtained when the amount is approximately 40% by weight or more.

<参考例1>収穫したたばこ葉の黄変について
葉表面の大部分が黄色に変色するまで保存してあった黄色種(FCV)たばこ葉について測色計にて測定した。その結果、葉表面の大部分を占める黄色に変色した部分の緑色度(a*値)は2.0±0.7であった。また、このたばこ葉をマイクロ波乾燥し、黄色のたばこ原料とした場合のa*値は5.3±0.1、また吸光度(ABS420nm)は1.57であった。
すなわちたばこ葉表面の大部分(面積の60%以上)の緑色度(a*値)が1.0より大きい値まで変化した場合“黄色に変色した葉”と言え、換言すると少なくともたばこ葉の大部分(面積の60%以上)のa*値が1.0以下でない限り本発明の効果は得られない。
なお、本発明の実験例に用いたバーレー種、黄色種、ニコチアナ・ルスチカの乾燥前たばこ葉(冷凍品)の緑色度(a*値)は、それぞれバーレー種:−2.1±0.3、黄色種:−2.5±0.6、ニコチアナ・ルスチカ:−4.6±0.5であった。
Reference Example 1 Yellowing of Harvested Tobacco Leaves Yellow seed (FCV) tobacco leaves that had been stored until most of the leaf surface turned yellow were measured with a colorimeter. As a result, the greenness (a * value) of the yellow-colored portion occupying most of the leaf surface was 2.0 ± 0.7. Further, when this tobacco leaf was microwave-dried to obtain a yellow tobacco raw material, the a * value was 5.3 ± 0.1, and the absorbance (ABS 420 nm) was 1.57.
That is, when the greenness (a * value) of most of the tobacco leaf surface (60% or more of the area) changes to a value greater than 1.0, it can be said to be a “yellow-colored leaf”, in other words at least the size of the tobacco leaf. The effect of the present invention cannot be obtained unless the a * value of the portion (60% or more of the area) is 1.0 or less.
In addition, the greenness (a * value) of the tobacco leaf (frozen product) before drying of the Burley species, the yellow species, and Nicotiana rustica used in the experimental examples of the present invention was Burley species: −2.1 ± 0.3, respectively. Yellow species: -2.5 ± 0.6, Nicotiana rustica: -4.6 ± 0.5.

(たばこ原料の褐変関与酵素の活性測定方法について)
たばこ原料について、加熱する工程を含ませることによる効果を確認するために、加熱処理しないたばこ葉(凍結乾燥のみを実施したバーレー種(みちのく)、凍結乾燥のみを実施したバーレー種(Burley21))と、本発明で加熱および水分を低下させる工程を経たたばこ原料の褐変関与酵素の活性値を測定する実験を行った。
各たばこ原料の褐変関与酵素(PPO)活性の測定は以下のように行った。水分5重量%以下までたばこ葉を乾燥し、粉砕した試料200mgに対して20mMリン酸カリウム緩衝液(pH6.0)10mLを加え、氷冷環境下で2分間ホモジナイズし、さらに氷冷環境下で10分間超音波を照射して酵素タンパクを抽出した。この溶液を0.20μm孔径のセルロースアセテートフィルター素材のメンブレンフィルター(ADVANTEC Cellulose Acetate filter)を用いてろ過した。PPO活性測定は、以上に述べた酵素タンパク溶液と0.1Mリン酸カリウム緩衝液(pH6.0)、そして基質となるピロカテコール溶液を用いた。活性測定の手順を次に示す。0.1Mリン酸カリウム緩衝液900μLと、上述の方法で調製した酵素タンパク質抽出液100μLを分光吸光光度計用セル内で混合する。対照として、0.1Mリン酸カリウム緩衝液900μLと脱イオン水100μLを混合し、これをリファレンスとする。40℃に設定された環境下で、サンプルとリファレンスに対して10mMピロカテコール溶液を1.00mL混合し、40℃における、リファレンスに対する420nm波長の吸光度の増加を観測した。測定は基質投入直後から15秒後〜60秒後の間の吸光度増加速度を観測する。
加熱処理しないたばこ葉の酵素活性値は、4.64U(凍結乾燥葉、バーレー種(みちのく))、6.42U(凍結乾燥葉バーレー種(Burley21))であったのに対し、加熱及び水分を低下させる工程を経たたばこ原料の酵素活性値は全て0.02U以下であった。このことから、たばこ葉の加熱処理がPPO活性の不活化に有効であるといえる。

(About the method for measuring the activity of browning-related enzymes in tobacco materials)
To confirm the effect of including a heating process for tobacco raw materials, tobacco leaves that are not heat-treated (Burley seeds that were only freeze-dried (Michinoku), Burley seeds that were only freeze-dried (Burley 21)) and In the present invention, an experiment was conducted to measure the activity value of the enzyme responsible for the browning of the tobacco raw material that has undergone the steps of heating and reducing moisture.
The browning-related enzyme (PPO) activity of each tobacco raw material was measured as follows. Tobacco leaves were dried to a moisture content of 5% by weight or less, and 10 mL of 20 mM potassium phosphate buffer (pH 6.0) was added to 200 mg of the crushed sample, and homogenized for 2 minutes in an ice-cooled environment. The enzyme protein was extracted by irradiating ultrasonic waves for 10 minutes. This solution was filtered using a membrane filter (ADVANTEC Cellulose Acetate filter) made of cellulose acetate filter material having a pore diameter of 0.20 μm. The PPO activity was measured using the enzyme protein solution described above, 0.1 M potassium phosphate buffer (pH 6.0), and a pyrocatechol solution as a substrate. The procedure for measuring the activity is as follows. 900 μL of 0.1 M potassium phosphate buffer and 100 μL of the enzyme protein extract prepared by the above method are mixed in the spectrophotometric cell. As a control, 900 μL of 0.1 M potassium phosphate buffer and 100 μL of deionized water are mixed and used as a reference. Under an environment set at 40 ° C., 1.00 mL of a 10 mM pyrocatechol solution was mixed with the sample and the reference, and an increase in absorbance at 420 nm wavelength with respect to the reference at 40 ° C. was observed. In the measurement, the rate of increase in absorbance is observed between 15 seconds and 60 seconds after the substrate is introduced.
The enzyme activity values of the tobacco leaves that were not heat-treated were 4.64 U (freeze-dried leaves, Burley species (Michinoku)) and 6.42 U (freeze-dried leaf Burley species (Burley 21)). All the enzyme activity values of the tobacco raw materials that had undergone the step of decreasing were 0.02 U or less. From this, it can be said that the heat treatment of tobacco leaves is effective for inactivating the PPO activity.
