香料ビーズおよびシガレット用フィルタ 技術分野  Perfume beads and cigarette filters
[0001] 本発明は、香料ビーズおよびこれを含むシガレット用フィルタに関する。  [0001] The present invention relates to a perfume bead and a cigarette filter including the same.
背景技術  Background art
[0002] 葉タバコ刻に添加される香料には、ケーシングソースとしての第 1香料とトップフレ 一バーとしての第 2香料が含まれる。第 2香料の成分は、比較的揮発性が高ぐまた 熱分解を受けやすい。したがって、第 2香料を有するシガレットは、その保管中に第 2 香料が揮散し、喫煙時の香喫味が減少するば力、りでなぐチヤコールフィルタを備え たシガレットにおいては、第 2香料がチヤコールに移行 ·吸着されて一層香喫味が減 少する。第 2香料を吸着したチヤコールは、タバコの主流煙中の成分除去能が低下 する。  [0002] The flavor added to the tobacco leaf includes a first flavor as a casing source and a second flavor as a top flavor. The components of the second fragrance are relatively volatile and susceptible to thermal decomposition. Therefore, for cigarettes with a second fragrance, if the second fragrance is volatilized during storage and the savory taste during smoking is reduced, the second fragrance is chiacoal.・ Adsorption is further reduced. Tiacol adsorbed with the second fragrance will reduce the ability to remove components in the mainstream smoke of tobacco.
[0003] 特許第 2709077号明細書は、第 2香料を、天然多糖類でマイクロカプセル化し、 そのマイクロカプセルをいわゆるキヤビティ充填によりタバコフィルターに添加すること を開示している。香料は、天然多糖類からなるマイクロカプセル内に封入されている ため、保管時の香料の移行、揮散が生じず、したがって、チヤコールフィルタとともに 用いても、チヤコールフィルタの、タバコの主流煙中の成分除去能を低下させることも ない。  [0003] Japanese Patent No. 2709077 discloses that the second fragrance is microencapsulated with a natural polysaccharide and the microcapsules are added to a tobacco filter by so-called cavity filling. Since the fragrance is enclosed in microcapsules made of natural polysaccharides, the fragrance does not migrate or volatilize during storage. Therefore, even when used with a Thiakol filter, the Thiakol filter contains the mainstream smoke of tobacco. It does not reduce the component removal ability.
[0004] しかしながら、マイクロ化カプセル中の香料は、シガレットの喫煙時に指で押し潰し たり、擦り潰したりすること（外力の適用）によって、初めて味わうことができるものであ る。しかし、外力の適用は面倒であり、また外力の適用によって流出した香料はフィ ルタ全体に均一に分布し得ず、その結果喫煙時の喫味が一定しない。  [0004] However, the fragrance in the microcapsule can be tasted for the first time by crushing or crushing with a finger (application of external force) when smoking a cigarette. However, the application of external force is cumbersome, and the fragrance discharged by the application of external force cannot be evenly distributed throughout the filter, resulting in a non-uniform taste during smoking.
発明の開示  Disclosure of the invention

This fragrance bead 20 is such that the entire surface of the particulate carrier (core) 22 is covered with a solid fragrance film 24 like menthol, and the entire surface of the solid fragrance film 24 is covered with a gnolecan film 26! /. .
[0021] 固体香料膜 24は、後述するように、メントールのような固体香料の結晶を微粉末化 し、粒子状担体 12と混合し、固体香料微粉末を粒子状担体 22に付着させ、これを粒 子状担体 22上で加熱溶融した後、冷却により再結晶化させることにより形成すること ができる。この冷却時にメントール等の固体香料を柱状結晶となるまで成長させない ようにするために、固体香料に脂肪酸、グリセリン、プロピレングリコール等の結晶成 長抑制剤を添加しておくことが好ましい。この結晶成長抑制剤は、メントール等の固 体香料の重量の 0. ；!〜 1. 0%に相当する量で用いることができる。また、固体香料 膜 14には、固体香料以外の香料を含めることができる。  [0021] As will be described later, the solid fragrance film 24 is obtained by finely pulverizing a solid fragrance crystal such as menthol and mixing it with the particulate carrier 12, and attaching the solid fragrance fine powder to the particulate carrier 22. It can be formed by heating and melting on a granular carrier 22 and then recrystallizing by cooling. In order to prevent the solid fragrance such as menthol from growing until it becomes columnar crystals during cooling, it is preferable to add a crystal growth inhibitor such as fatty acid, glycerin, propylene glycol or the like to the solid fragrance. This crystal growth inhibitor can be used in an amount corresponding to 0.;! To 1.0% of the weight of the solid fragrance such as menthol. Further, the solid fragrance film 14 can contain a fragrance other than the solid fragrance.
[0022] 固体香料膜 24の厚さに特に制限はないが、固体香料膜 24は、最終香料ビーズの 重量の 1〜20%に相当する量の固体香料により形成することが好ましい。  [0022] The thickness of the solid fragrance film 24 is not particularly limited, but the solid fragrance film 24 is preferably formed of a solid fragrance in an amount corresponding to 1 to 20% of the weight of the final fragrance bead.

The thickness of the gnolecan film 26 is not particularly limited. However, the glucan film 26 is 0.2% of the weight of the final fragrance bead from the viewpoint of the retention of solid fragrance when not smoked and the ability to release menthol when smoked. It is preferable to form with an amount of dulcan corresponding to 5 to 5%.
[0024] 第 2の態様に係る香料ビーズは、例えば、次の方法により製造することができる。す なわち、粒子状担体と固体香料結晶の微粉末および必要に応じて結晶成長抑制剤 、他の香料をリボンミキサーで混合 ·加熱する。この混合初期には、固体香料結晶の 微粉末が各粒子状担体の表面に付着し、加温温度が固体香料の融点（例えばメント ールでは約 42°C)となったところで固体香料結晶の微粉末が溶融し始める。攪拌混 合を続けることで、溶融した固体香料が各粒子状担体の表面に均一に塗布される。 この加温混合後、例えばリボンミキサー缶体を冷却する力、、あるいはリボンミキサー内 に冷風を吹き込むことにより、粒子状担体を速やかに冷却する。この冷却により、溶 融した固体香料は再結晶化し、各粒子状担体の表面を膜状に覆うことができる。この 固体香料膜で覆われた粒子状担体を、流動造粒乾燥機に入れ、例えば 40°C以下 の温風を吹き込みながら、グルカンの水溶液ある!/、はグルカンの水分散液等を間欠 的に噴霧し、冷却する。こうして、粒子状担体の表面に形成された固体香料膜の表 面にダルカンの皮膜が形成される。 [0024] The perfume beads according to the second embodiment can be produced, for example, by the following method. In other words, the particulate carrier, fine powder of solid fragrance crystals, and if necessary, a crystal growth inhibitor and other fragrances are mixed and heated with a ribbon mixer. At the beginning of this mixing, the fine powder of solid fragrance crystals adheres to the surface of each particulate carrier, and when the heating temperature reaches the melting point of the solid fragrance (for example, about 42 ° C in menthol), The fine powder begins to melt. By continuing the stirring and mixing, the molten solid fragrance is uniformly applied to the surface of each particulate carrier. After this warming and mixing, the particulate carrier is rapidly cooled, for example, by cooling the ribbon mixer can body or by blowing cold air into the ribbon mixer. This cooling The melted solid fragrance can be recrystallized to cover the surface of each particulate carrier in the form of a film. The particulate carrier covered with this solid fragrance film is put into a fluidized granulator and dried with a glucan aqueous solution while blowing hot air at 40 ° C or lower, for example! Spray onto and cool. In this way, a Dalkan film is formed on the surface of the solid fragrance film formed on the surface of the particulate carrier.
