カプセル内容物は、水を主成分として油性成分を含む態様、油性成分を主成分として含む態様、および油性成分のみで構成される態様のいずれも取ることができる。「油性成分を主成分として含む」とは、具体的には、カプセル内容物の全重量に対し、油性成分が、例えば50重量%以上、好ましくは60重量%以上、より好ましくは70重量%以上、さらに好ましくは80重量%以上を占めることをいうものとする。「水を主成分として油性成分を含む」とは、具体的には、カプセル内容物の全重量に対し、水成分が、例えば80重量%以下、好ましくは70重量%以下、より好ましくは60重量%以下を占めることをいうものとする。
本発明のシームレスカプセルでは、カプセル内容物の外側に中間層が形成される。中間層は、少なくとも1層であり、複数層でも良い。複数層の場合は、同じ配合で用いても、違う配合で用いてよいが、通常中間層は1層である。以下、簡単のため中間層が1層として説明する。中間層では、カプセル内容物の調製に用いることができる油性組成物として、例えば、オリーブ油、ホホバ油、コーン油、ナタネ油、豚脂、牛脂、鯨油、ビーズワックス、ヒマシ油、大豆油、米油、米胚芽油、ヤシ油、パーム油、カカオ油、アボガド油、マカデミアナッツ油、スクワラン、ミンク油、タートル油、コーン油、中鎖脂肪酸トリグリセリド(MCT)、長鎖脂肪酸トリグリセリド(LCT)、炭素数が8~30の炭化水素類、ミツロウ、カルナウバロウ、ライスワックス、ラノリン、流動パラフィン、ワセリン、炭素数が4~30の脂肪酸、炭素数が4~30の脂肪酸とショ糖とのエステル、炭素数が4~30の脂肪酸とグリセロールとのエステル、炭素数が4~30の脂肪族アルコール、炭素数が4~30の脂肪酸と炭素数が4~30の脂肪族アルコールとのエステル、およびシリコーンオイル、などが挙げられる。これらの1種のみで用いてもよく、また2種以上を混合して用いてもよい。これらの油性組成物のうち、-30℃~60℃の温度範囲において粘度が200mPa・s以下である液状油脂がより好ましい。
中間層を更に皮膜層で被覆する。皮膜層は、脱アシル型ゲランガムおよび修飾デンプンを含有する。ゲランガム(「ジェランガム」とも呼ばれる。)は、グラム陰性菌であるPseudomonas elodeaにより産出される水溶性多糖類であり、直鎖状のヘテロ多糖類で、グルコース、グルクロン酸、グルコース、ラムノースの4つの糖の繰り返し単位から構成されている。ゲランガムには1-3結合したグルコースに存在するアセチル基とグリセリル基の有無によって脱アシル型ゲランガムとネイティブ型ゲランガムの2種類があり、本発明においては脱アシル型ゲランガムが用いられる。脱アシル型ゲランガムは、市販品が用いられ、ケルコゲル(KELCOGEL:商標)Fやゲルザン(GELZAN:商標)CM(共に、シーピーケルコ(CPKelco)社製)が挙げられる。
結晶セルロースは、微結晶セルロースとも称され、繊維性植物から得られたα-セルロースを酸で部分的に解重合して精製したものである。グルコース単位がβ(1→4)グリコシド結合でつながったものであり、水、希酸、および大抵の有機溶剤に溶解しないが、吸湿性を有する化合物である。各社より、アビセルPHシリーズ、セレックス101、セオルス、エムコセル、ビバセルシリーズ等が市販されている。セルロース誘導体は、上記セルロースの水酸基がアルキルエーテル(-O-M)基ないし脂肪酸エステル基(-C(=O)-M)(M:アルキル)で置換された化合物であり、水等に溶解する性質を有する。
上述のように、本発明のシームレスカプセルは、特定の割れ性能、具体的には外圧を加えることにより、カプセル皮膜が破裂し、好ましくはシームレスカプセルが破裂時に弾け、破裂音をたてる性能を有する。そのため本発明のシームレスカプセルは、以下のような割れ特性を有する。
本発明のシームレスカプセルは、いわゆる滴下法と呼ばれる製造方法で製造される。滴下法は、ノズルから液滴を流体中に滴下して、表面張力で球状になる現象を利用して製造する方法である。本発明のシームレスカプセルは、前述のように、カプセル内容物と皮膜層との2層構造を有しても良く、またカプセル内容物と皮膜層の間に中間層を有する3層構造を有してもよいので、2層構造を有する場合の製造方法と、3層構造を有する場合の製造方法とを記載する。
内側ノズルと外側ノズルと、が同心円状に存在する二重ノズルから同時に吐出した吐出液を冷却液中に滴下する滴下法によるシームレスカプセルの製造方法であって、
内側ノズルからカプセル内容物液を吐出し、
外側ノズルから皮膜層液を吐出し、
前記カプセル内容物液が、油性成分を含み、かつカプセル内容物液の温度を5℃~30℃(好ましくは10~30℃)の範囲で設定値±2℃(好ましくは±1℃)に制御し、
前記皮膜層液が、少なくとも脱アシル型ゲランガムおよび修飾デンプンを含み、かつ皮膜層液の温度を60℃~90℃の範囲で設定値±2℃(好ましくは±1℃)に制御し、
前記冷却液が、油を含み、かつ冷却液の温度を10℃~30℃(好ましくは12~30℃)の範囲で設定値±2℃(好ましくは±1℃)に制御し、
前記皮膜層液の温度と前記冷却液の温度との差が、30℃以上80℃以下(好ましくは35℃以上73℃以下)の範囲に制御する、ことにより製造される。
内側ノズルと、中間ノズルと、外側ノズルと、が同心円状に存在する三重ノズルから同時に吐出した吐出液を冷却液中に滴下する滴下法によるシームレスカプセルの製造方法であって、
内側ノズルからカプセル内容物液を吐出し、
中間ノズルから中間層液を吐出し、
外側ノズルから皮膜層液を吐出し、
前記カプセル内容物液が、油性成分を含み、かつカプセル内容物液の温度を5℃~30℃(好ましくは10~30℃)の範囲で設定値±2℃(好ましくは±1℃)に制御し、
