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係り、より具体的には、タバコ固有のニトロソアミンが低減した口腔タバコ材料の製造方法、およびその製造方法により得られた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. More specifically, the present invention relates to a method for producing an oral tobacco material with reduced nitrosamine inherent to tobacco, and an oral tobacco material obtained by the production method.
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、通常のシガレット用タバコ材料と同様、ニコチン、ニトロソアミン類（タバコ固有のニトロソアミンを含む）、炭化水素類、タンパク質等種々の成分が含まれている。これらの成分には、喫味または他の理由から、除去しないか、あるいは増加させる方が望ましいものがある一方、その量を減少させることが望ましいものもある。タバコ固有のニトロソアミンは、その量を減少させることが望ましい。 The oral tobacco materials used in such oral tobacco products include various components such as nicotine, nitrosamines (including tobacco-specific nitrosamines), hydrocarbons, and proteins, as in the case of ordinary cigarette tobacco materials. ing. While some of these ingredients are not removed or increased for taste or other reasons, it is desirable to reduce their amounts. It is desirable to reduce the amount of tobacco-specific nitrosamines.
本発明の課題は、タバコ固有のニトロソアミン（ＴＳＮＡ）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。 An object of the present invention is to provide a method capable of producing an oral tobacco material having a reduced content of tobacco-specific nitrosamine (TSNA).
上記課題を解決するために、本発明の第１の側面によると、８以下のｐＨ値を示す口腔用乾燥タバコ材料からなる原料タバコ材料に、抗酸化剤を添加し、この抗酸化剤添加した原料タバコ材料を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。 In order to solve the above-mentioned problem, according to the first aspect of the present invention, an antioxidant is added to a raw tobacco material composed of a dry oral tobacco material having a pH value of 8 or less, and this antioxidant is added. There is provided a method for producing an oral tobacco material, wherein the raw 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。 Moreover, according to the 2nd side surface of this invention, the oral tobacco material manufactured by the manufacturing method of the oral tobacco material of this invention is provided.
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ＴＳＮＡ含有量を示す。 Oral tobacco materials made according to the present invention exhibit significantly reduced TSNA 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.
本発明の口腔タバコ材料の製造方法において、８以下のｐＨ値を示す口腔用乾燥タバコ材料を原料材料として用いる。通常、４以上のｐＨ値を示す口腔用乾燥タバコ材料を原料材料として用いる。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 the method for producing an oral tobacco material of the present invention, a dry oral tobacco material having a pH value of 8 or less is used as a raw material. Usually, a dry oral tobacco material having a pH value of 4 or more is used as a raw material. In this specification, the pH of the dry 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 for 10 minutes at room temperature, and allowing to stand for 5 minutes. The pH of the obtained extract is a value measured with a pH meter (IQ Scientific Instruments Inc. IQ240).
原料タバコ材料としては、初めから８以下のｐＨ値を示すものとして製造される口腔用乾燥タバコ材料と、８を超えるｐＨ値を示すものとして製造される口腔用乾燥タバコ材料に酸性物質を添加してｐＨ値を８以下に低下させたものが含まれる。 As the raw material tobacco material, an acidic substance is added to the dry oral tobacco material manufactured to exhibit a pH value of 8 or less from the beginning and the dry oral tobacco material manufactured to exhibit a pH value of more than 8. In which the pH value is lowered to 8 or less.
前者の初めから８以下のｐＨ値を示すものとして製造される口腔用乾燥タバコ材料には、黄色種（flue-cured tobacco）、バーレー種（burley tobacco）、暗色気干葉（dark air-cured tobacco）、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。 From the beginning of the former, dry oral tobacco materials produced with a pH value of 8 or less include flue-cured tobacco, burley tobacco, and dark air-cured tobacco. Examples thereof include dark fire-cured tobacco, air-cured tobacco by early-dehydrating, sun-cured tobacco, oriental tobacco, and the like.
後者の８を超えるｐＨ値を示すものとして製造される口腔用乾燥タバコ材料としては、バーレー種、暗色気干葉、気干葉（air-cured tobacco）等の一部を例示することができる。このタバコ材料に添加す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。また、これら有機酸の代わりに、酸性（すなわちｐＨ７未満）を示す口腔用乾燥タバコ材料（黄色種、バーレー種、暗色気干葉、暗色火干葉、青干葉、日干葉、オリエンタル等）を用いることもできる。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。 Examples of the dry tobacco material for oral cavity produced as a material having a pH value exceeding 8 of the latter include burley species, dark air-cured leaves, air-cured tobacco, and the like. As an acidic substance added to the tobacco material, organic acids such as citric acid, ascorbic acid, acetic acid, lactic acid, malic acid, tartaric acid, and succinic acid can be used. In addition, instead of these organic acids, dry oral tobacco materials (yellow, burley, dark-colored dry leaves, dark-fired dry leaves, green dry leaves, sun-dried leaves, oriental, etc.) exhibiting acidity (ie, less than pH 7) may be used it can. 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、上記原料タバコ材料に抗酸化剤を添加する。抗酸化剤は、原料タバコ材料中に含まれるＴＳＮＡを有意に減少させる。ＴＳＮＡには、代表的なものとして、Ｎ’−ニトロソノルニコチン（ＮＮＮ）、４−（メチルニトロソアミノ）−１−（３−ピリジル）−１−ブタノン（ＮＮＫ）およびＮ’−ニトロソアナタビン（ＮＡＴ）が含まれる。抗酸化剤としては、エピガロカテキンガレート、アスコルビン酸、緑茶エキス等を例示することができる。なお、アスコルビン酸は、上述の通り、ｐＨ調整用の酸性物質でもあるが、抗酸化剤として、別の酸性物質と併用してもよく、あるいは、酸性物質としての効果を兼ねて単独で使用してもよい。抗酸化剤は、原料タバコ材料１００重量部当たり、１〜１００重量部の割合で添加することが好ましい。 Next, an antioxidant is added to the raw tobacco material. Antioxidants significantly reduce TSNA contained in the raw tobacco material. TSNA typically includes N′-nitrosonornicotine (NNN), 4- (methylnitrosoamino) -1- (3-pyridyl) -1-butanone (NNK) and N′-nitrosoanatabine ( NAT). Examples of the antioxidant include epigallocatechin gallate, ascorbic acid, green tea extract and the like. Ascorbic acid is also an acidic substance for pH adjustment as described above. However, ascorbic acid may be used in combination with another acidic substance as an antioxidant, or used alone as an acidic substance. May be. The antioxidant is preferably added at a rate of 1 to 100 parts by weight per 100 parts by weight of the raw tobacco material.
次に、抗酸化剤を添加した原料タバコ材料を８０℃以上の温度で加熱する。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 raw tobacco material to which the antioxidant is added is heated at a temperature of 80 ° C. or higher. The heating temperature is usually 130 ° C. or lower. Moreover, heating time is 10 minutes-30 minutes normally.
１００℃を超える温度で原料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）に原料タバコ材料を入れ、上記導入管から原料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 raw tobacco material at a temperature exceeding 100 ° C., the raw 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. The heating steam can be directly blown into the raw tobacco material from the introduction pipe, and the heating steam can be circulated in the jacket to heat the tobacco material at the temperature of the heating steam.
なお、原料タバコ材料中に含まれる亜硝酸塩は、原料タバコ材料が８以下のｐＨ値において不安定となり、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。従って、本発明の方法により、原料タバコ材料中のＴＳＮＡを減少させることができるとともに、硝酸塩をも減少させることができる。 The nitrite contained in the raw tobacco material becomes unstable when the raw tobacco material is at a pH value of 8 or less, and nitrous acid can be decomposed and released as NOx gas by heating at 80 ° C. or higher. Therefore, according to the method of the present invention, TSNA in the raw tobacco material can be reduced, and nitrate can also be reduced.
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。 EXAMPLES Next, although an Example demonstrates this invention, this invention is not limited by these Examples.
