Abstract
Description
また、旨味やコクを増加させる方法として茶葉原料をプロテアーゼ及びタンナーゼの存在下に抽出する方法(特許文献3)、また、セルラーゼ、ヘミセルラーゼ、ペクチナーゼ及びプロトペクチナーゼを少なくとも有する酵素群を用い、茶葉を酵素分解抽出処理する方法(特許文献4)、茶類原料の抽出時および/または抽出後に糖類分解酵素を用いて酵素分解処理する茶エキスの製造方法(特許文献5)が開示されている。
しかし、これらの製法は長期保管における沈殿の発生の防止、旨味の増強、渋味の低減などを目的とした製法であり、香りの観点では満足の出来るものではなかった。
また、茶類の香気を酵素によって高める方法として、緑茶の抽出液に配糖体分解酵素を作用させる製法(特許文献6)、茶葉にタンナーゼ処理時又は処理後に配糖体分解酵素を作用させる製法(特許文献7)、微生物由来のジグリコシダーゼを作用させる方法(特許文献8)が知られている。
しかし、これらの製法で使用される配糖体分解酵素は非常に高価であり、工業的に利用することに問題があった。
製造中、保存中の香りの損失を補うべく、化学的に合成された香気物質を調合して得る香料を添加する場合もあるが、近年の食品の安全性への消費者意識の高まり、天然志向の高まりから、特に茶系飲料への香料の使用は敬遠される傾向があった。
すなわち、本発明は、原料茶類から茶エキスを抽出する時及び/又は抽出した後、多糖類分解酵素処理を行う茶エキスの製造方法であって、多糖類分解酵素処理時の茶エキスのpHが3~7であり、処理時間が3~48時間である、前記製造方法を提供する。
また、本発明は、原料茶類から茶エキスを抽出する時及び/又は抽出した後に多糖類分解酵素処理した茶エキスであって、Brix 1%当たりのサリチル酸メチルの含有量が40ppb以上である、前記茶エキスを提供する。
さらに、本発明は、上記製造方法により得られる茶エキス又は上記茶エキスを配合して得られる容器詰茶飲料を提供する。
本発明においては、ツバキ科の植物チャ(学術名Camellia sinensis)の芽及び葉を原料とする茶であれば原料茶類として限定なく用いることができる。茶には、中国種(Camellia sinensis var sinensis)、アッサム種(Camellia sinensis var assamica)、カンボジア種(Camellia sinensis var ssp. lasiocalyx)などがあり、本発明ではそのいずれも用いることができる。具体的には、不醗酵茶(煎茶、かぶせ茶、玉露、碾茶、抹茶、玉緑茶、番茶、ほうじ茶、釜炒茶など)、半醗酵茶(包種茶、鉄観音茶、ウーロン茶など)、醗酵茶(紅茶、阿波番茶、碁石茶、富山黒茶、磚茶、プーアール茶など)が挙げられる。上記の茶を複数種適度な割合でブレンドしたものを用いてもよい。
多糖類分解酵素処理時の茶エキスのpHは、3~7であり、好ましくは4~5.5である。多糖類分解酵素処理の処理時間は、3~48時間であり、好ましくは10~24時間である。多糖類分解酵素処理の処理温度は、好ましくは10~60℃であり、より好ましくは20℃~50℃である。処理条件が上記範囲内であれば、サリチル酸メチルを効率よく充分量発生させることができる。
