Description
本発明は、口腔タバコ材料の製造方法および口腔タバコ材料に関する。
The present invention relates to a method for producing an oral tobacco material and an oral tobacco material.
近年、スヌース等の口腔タバコ製品が注目されてきている。これら口腔タバコ製品は、粉末タバコ等を含む口腔タバコ材料を、水分透過性のポーチに収容したもので、口腔内で唇と歯茎の間に挿入し、粉末タバコの味・香りを楽しむものである（例えば、特許文献１参照）。
In recent years, oral tobacco products such as snus have attracted attention. These oral tobacco products are obtained by containing oral tobacco materials including powdered tobacco in a moisture-permeable pouch and inserted between the lips and gums in the mouth to enjoy the taste and aroma of powdered tobacco (for example, , See Patent Document 1).
このような口腔タバコ製品に使用される口腔タバコ材料には、亜硝酸塩が含まれている。亜硝酸塩は、刺激味を有することが知られており、特に口腔タバコ材料が亜硝酸塩を多く含むと、タバコ風味を損なう原因となる。そのため、スウェーデン国のある口腔タバコ製品製造会社は、口腔タバコ材料に含まれる亜硝酸量の上限を設定している。
The oral tobacco material used in such oral tobacco products contains nitrite. Nitrite is known to have an irritating taste, and in particular, when the oral tobacco material contains a large amount of nitrite, it causes a loss of tobacco flavor. Therefore, an oral tobacco product manufacturer in Sweden has set an upper limit on the amount of nitrous acid contained in oral tobacco materials.
亜硝酸塩に起因して風味が損なわれることのない口腔タバコ製品を提供するためには、亜硝酸塩含有量の少ない口腔タバコ材料を選んで用いることが必要である。しかしながら、そのような制約の下では、亜硝酸塩含有量を除くと口腔タバコ材料として良好な官能特性を有する口腔タバコ材料であっても、使用に不適切であるとして排除されてしまう。すなわち、亜硝酸塩含有量の少ない口腔タバコ材料を選んで用いるという制約は、使用し得る口腔タバコ材料に対する大きな制約である。
In order to provide an oral tobacco product whose flavor is not impaired due to nitrite, it is necessary to select and use an oral tobacco material having a low nitrite content. However, under such restrictions, even if the nitrite content is removed, even an oral tobacco material having good sensory characteristics as an oral tobacco material will be excluded as inappropriate for use. That is, the restriction of selecting and using an oral tobacco material having a low nitrite content is a great restriction on the oral tobacco material that can be used.
従って、本発明の課題は、小さい制約の下で、亜硝酸塩の含有量が低下した口腔タバコ材料を製造することができる方法を提供することである。
Therefore, an object of the present invention is to provide a method capable of producing an oral tobacco material having a reduced nitrite content under small restrictions.
本発明者らは、スヌース等の口腔タバコ材料はアルカリ性成分を添加することにより良好な風味が引き出されるということが当該分野でよく知られているところ、酸性物質を添加し、所定の温度で加熱することにより、口腔タバコ材料中の亜硝酸（塩）量を大幅に低下させ得ることを見いだした。本発明は、かかる知見に基づく。
The present inventors are well known in the art that oral tobacco materials such as snus can bring out a good flavor by adding an alkaline component. However, an acidic substance is added and heated at a predetermined temperature. By doing so, it has been found that the amount of nitrous acid (salt) in the oral tobacco material can be significantly reduced. The present invention is based on such knowledge.
すなわち、本発明の第１の側面によると、８を超えるｐＨ値を示す口腔用乾燥タバコ材料からなる出発材料に、酸性物質を添加することによりｐＨ値を８以下に低下させ、前記酸性物質を添加したタバコ材料を８０℃以上の温度で加熱することを特徴とする口腔タバコ材料の製造方法が提供される。
That is, according to the first aspect of the present invention, an acidic substance is added to a starting material made of a dry tobacco material for oral cavity exhibiting a pH value exceeding 8, whereby the pH value is lowered to 8 or less, There is provided a method for producing an oral tobacco material, wherein the added tobacco material is heated at a temperature of 80 ° C. or higher.
また、本発明の第２の側面によると、本発明の口腔タバコ材料の製造方法により製造された口腔タバコ材料が提供される。
Also, according to the second aspect of the present invention, there is provided an oral tobacco material produced by the method for producing an oral tobacco material of the present invention.
本発明により製造された口腔タバコ材料は、有意に低減された亜硝酸含有量を示す。
The oral tobacco material produced according to the present invention exhibits a significantly reduced nitrite content.
以下、本発明の種々の実施の形態について、詳細に説明する。
Hereinafter, various embodiments of the present invention will be described in detail.
本発明によると、口腔タバコ材料は、８を超えるｐＨ値を示す口腔用乾燥タバコ材料からなる出発材料に、酸性物質を添加することにより前記ｐＨ値を８以下に低下させ、前記酸性物質を添加した口腔タバコ材料を８０℃以上の温度で加熱することにより製造される。
According to the present invention, the oral tobacco material reduces the pH value to 8 or less by adding an acidic substance to the starting material composed of the dry oral tobacco material exhibiting a pH value exceeding 8, and the acidic substance is added. It is produced by heating the prepared oral tobacco material at a temperature of 80 ° C. or higher.
本発明においては、８を超えるｐＨ値を示す口腔用乾燥タバコ材料を出発材料として用いる。通常、８を超え、１０以下のｐＨ値を示す口腔用乾燥タバコ材料を出発材料として用いる。かかるｐＨ値を示す口腔タバコ材料は、豊富に作られており、大きな制約とはならないであろう。出発材料としては、バーレー種（burley tobacco）、暗色気干葉（dark air-cured tobacco）、気干葉（air-cured tobacco）等の一部を例示することができる。
In the present invention, a dry oral tobacco material having a pH value exceeding 8 is used as a starting material. Usually, dry oral tobacco material having a pH value of more than 8 and not more than 10 is used as a starting material. Oral tobacco materials exhibiting such pH values are abundantly made and would not be a major limitation. Examples of starting materials include burley seeds (burley tobacco), dark air-cured actobacco, and air-cured cotobacco.
本明細書において、乾燥タバコ材料のｐＨは、タバコ材料２～１０ｇに１０倍の２０～１００gの蒸留水を加え、室温で水とたばこの混合物を２００ｒｐｍで１０分間振盪し５分間静置した後、得られた抽出液のｐＨをｐＨメーター（IQ Scientific Instruments Inc.製IQ240）で測定した値を指す。
In this specification, the pH of the dried tobacco material is determined by adding 20 to 100 g of distilled water 10 times to 2 to 10 g of tobacco material, shaking the mixture of water and tobacco at 200 rpm at room temperature for 10 minutes, and allowing to stand for 5 minutes. The pH of the resulting extract is a value measured with a pH meter (IQ Scientific Instruments Inc. IQ240).
本発明では、まず、出発材料に、酸性物質を添加することにより、そのｐＨ値を８以下に低下させる。通常、酸性物質の添加により、ｐＨ値を４～８に低下させる。酸性物質としては、クエン酸、アスコルビン酸、酢酸、乳酸、リンゴ酸、酒石酸、コハク酸等の有機酸を用いることができる。
In the present invention, first, an acidic substance is added to the starting material to lower its pH value to 8 or less. Usually, the pH value is lowered to 4-8 by the addition of acidic substances. As the acidic substance, organic acids such as citric acid, ascorbic acid, acetic acid, lactic acid, malic acid, tartaric acid, and succinic acid can be used.
また、上記酸性物質として、有機酸の代わりに、酸性（すなわちｐＨ７未満）を示す口腔用乾燥タバコ材料を用いることもできる。かかる酸性を示す口腔用乾燥タバコ材料としては、黄色種（flue-cured tobacco）、バーレー種、暗色気干葉、暗色火干葉（dark fire-cured tobacco）、青干葉（air-cured tobacco by early-dehydrating）、日干葉（sun-cured tobacco）、オリエンタル（oriental tobacco）等を例示することができる。酸性物質として酸性を示す口腔用乾燥タバコ材料を用いる場合、その量は、出発材料の重量の１００％以下であることが好ましい。
Further, as the above acidic substance, dry tobacco material for oral cavity exhibiting acidity (that is, pH less than 7) can be used instead of the organic acid. Such dry tobacco materials for oral use exhibiting acidity include yellow (flue-curedbtobacco), burley, dark-fired, dark-fired (dark fire-cured tobacco), and green (air-cured tobacco by early-dehydrating) ), Sun-cured tobacco, oriental tobacco, and the like. When using the dry oral tobacco material which shows acidity as an acidic substance, it is preferable that the quantity is 100% or less of the weight of a starting material.
次に、酸性物質を添加した出発材料を８０℃以上の温度で加熱する。亜硝酸塩は、ｐＨ８を超えるアルカリ性条件下では、安定に存在するが、本発明により、ｐＨ値が８以下に低下されると、不安定となり、８０℃以上の加熱により、亜硝酸をＮＯｘガスとして分解放出させることができる。加熱温度は、通常、１３０℃以下である。また、加熱時間は、通常、１０分～３０分である。
Next, the starting material to which the acidic substance has been added is heated at a temperature of 80 ° C. or higher. Nitrite is stably present under alkaline conditions exceeding pH 8, but becomes unstable when the pH value is lowered to 8 or less according to the present invention, and nitrite is converted into NOx gas by heating at 80 ° C. or higher. It can be decomposed and released. The heating temperature is usually 130 ° C. or lower. The heating time is usually 10 minutes to 30 minutes.
１００℃を超える温度でタバコ材料を加熱するためには、外側にジャケットを有し、かつ加熱蒸気の導入管と排出管を備えた密閉加熱容器（例えば、円筒状）にタバコ材料を入れ、上記導入管からタバコ材料中に加熱蒸気を直接吹き込むとともに、ジャケット内に加熱蒸気を循環させて、同加熱蒸気の温度でタバコ材料を加熱することができる。
In order to heat the tobacco material at a temperature exceeding 100 ° C., the tobacco material is put in a sealed heating container (for example, a cylindrical shape) having a jacket on the outside and provided with a heating steam introduction pipe and a discharge pipe. While the heating steam is blown directly into the tobacco material from the introduction pipe, the heating steam is circulated in the jacket, and the tobacco material can be heated at the temperature of the heating steam.
本発明によれば、出発材料中の亜硝酸量を９０％以上減少させることができる。
According to the present invention, the amount of nitrous acid in the starting material can be reduced by 90% or more.
なお、特開昭５０－１１１２９５公報に、アスコルビン酸等の化学物質をタバコ全体に分散させることにより、タバコ組成物を製造することが開示されている。しかしながら、この先行技術は、タバコを燃焼したときに発生するタバコ主流煙中の二酸化窒素の量を減少させるものであって、タバコ自体に含まれる二酸化窒素の量を減少させるものではない。
Note that Japanese Patent Laid-Open No. 50-111295 discloses that a tobacco composition is produced by dispersing a chemical substance such as ascorbic acid throughout the tobacco. However, this prior art reduces the amount of nitrogen dioxide in the mainstream smoke generated when tobacco is burned, and does not reduce the amount of nitrogen dioxide contained in the tobacco itself.
次に、本発明を実施例により説明するが、本発明は、それら実施例により限定されるものではない。

＜亜硝酸濃度の測定方法＞
サンプル中の亜硝酸と芳香族第一アミン（スルファニルアミド）を反応させ、ジアゾニウム塩を生成する。ジアゾニウム塩がＮ－（１－ナフチル）－エチレンジアミン（ＮＥＤ）とアゾカップリングし、赤紫色のアゾ化合物を生成する。この呈色部分の吸光度（５４０ｎｍ）を測定することでサンプル中の亜硝酸態窒素（Ｎ）の濃度を測定し、亜硝酸に換算する。
<Method of measuring nitrous acid concentration>
Nitrous acid in the sample and an aromatic primary amine (sulfanilamide) are reacted to form a diazonium salt. The diazonium salt is azo-coupled with N- (1-naphthyl) -ethylenediamine (NED) to produce a reddish purple azo compound. By measuring the absorbance (540 nm) of this colored portion, the concentration of nitrite nitrogen (N) in the sample is measured and converted to nitrous acid.
