Abstract
Description
本発明は、非重合体カテキン類含有容器詰飲料に関する。 The present invention relates to a non-polymer catechin-containing container-packed beverage.
カテキン類の効果としてはαアミラーゼ活性阻害作用などが報告されている。このような生理効果を発現させるためには、より簡便に大量のカテキン類を摂取する必要があるため、飲料にカテキン類を高濃度配合する技術が望まれていた。 As an effect of catechins, α amylase activity inhibitory action and the like have been reported. In order to express such a physiological effect, since it is necessary to ingest a large amount of catechins more easily, a technique for blending a high concentration of catechins in a beverage has been desired.
この方法の一つとして、緑茶抽出物の濃縮物などの茶抽出物を利用して、カテキン類を飲料に添加する方法が用いられている。しかしながら、例えば紅茶抽出液にカテキン類を高濃度に配合した場合、カフェイン及び緑茶由来の苦渋みの残存が飲料の商品価値を大きく損ねることがわかっている。 As one of the methods, a method of adding catechins to a beverage using a tea extract such as a concentrate of a green tea extract is used. However, for example, when catechins are blended at a high concentration in black tea extract, it has been found that the residual bitterness derived from caffeine and green tea greatly impairs the commercial value of beverages.
紅茶等の発酵茶抽出液に対してタンナーゼ処理を行い、低温冷却時の懸濁、すなわちティークリーム形成を抑制できることは古くから知られていた。又、特許文献１に見られるカテキンガレート体にタンナーゼ処理を行い、一部又は全部を没食子酸とすることにより、カテキン類と没食子酸との混合物を得る方法によれば、苦味の原因となるカテキンガレート体を低減することができるが、苦味をなくすこと、特に、後味の悪さについては、課題として残った。また、茶抽出物からカフェイン等の苦味を有する夾雑物を取り除く方法としては、吸着法（特許文献２〜４）、抽出法（特許文献５）等が知られている。
しかしながら、緑茶抽出物を配合した非重合体カテキン類を高濃度に含有する飲料において、非重合体カテキン類特有の苦みや渋みが気になり、途中で飲用を中止してしまう場合がある。また、飲料保存時に非重合体カテキン類特有の苦みや渋みが強調され嗜好性が下がる場合がある。
従って、本発明の目的は、高濃度に非重合体カテキン類を配合した飲料における苦みや渋みを緩和した容器詰飲料を提供することにある。
However, in beverages containing a high concentration of non-polymer catechins blended with green tea extract, the bitterness and astringency peculiar to non-polymer catechins may be worrisome and drinking may be stopped in the middle. Moreover, the bitterness and astringency peculiar to non-polymer catechins may be emphasized at the time of drink preservation, and palatability may fall.
Accordingly, an object of the present invention is to provide a packaged beverage that alleviates bitterness and astringency in beverages containing non-polymer catechins at a high concentration.
そこで本発明者は、緑茶抽出物を配合した非重合体カテキン類を高濃度に含有する飲料に、種々のフレーバー成分を配合して、苦みや渋みに対する影響を検討してきたところ、柑橘類に多く含まれているリモネンに比べて、特定の成分を非重合体カテキン類に対して一定の比率で配合することにより、非重合体カテキン類特有の苦みや渋みが緩和され、おいしく飲める飲料が得られることを見出した。 Therefore, the present inventor has examined the influence on bitterness and astringency by blending various flavor components into a beverage containing a high concentration of non-polymer catechins blended with a green tea extract, and it contains a lot of citrus fruits. Compared to limonene, certain ingredients are blended at a certain ratio with respect to non-polymer catechins, so that the bitterness and astringency peculiar to non-polymer catechins are alleviated and a drink that can be enjoyed deliciously is obtained. I found.
すなわち、本発明は、緑茶抽出物を配合したｐＨ２〜６の容器詰飲料であって、
次の成分（Ａ）及び（Ｂ）：
（Ａ）非重合体カテキン類 ０．０３〜０．６質量％、
（Ｂ）ヘキサノール、ｃｉｓ−３−ヘキセノール、プロピオン酸、酢酸エチル、１−ｐ−メンタン−８−チオール及び酪酸エチルよりなる群から選ばれる１種以上
を（Ｂ）／（Ａ）（質量比）が０．０００１〜５の範囲で含有する容器詰飲料を提供するものである。
That is, the present invention is a packaged beverage having a pH of 2 to 6 containing a green tea extract,
The following components (A) and (B):
(A) Non-polymer catechins 0.03-0.6 mass%,
(B) One or more selected from the group consisting of hexanol, cis-3-hexenol, propionic acid, ethyl acetate, 1-p-menthane-8-thiol and ethyl butyrate (B) / (A) (mass ratio) Is a container-packed beverage containing 0.0001-5.
本発明の容器詰飲料は、生理効果を奏するのに十分な量の非重合体カテキン類を含有しながら、非重合体カテキン類特有の苦みや渋みが緩和され、苦みや渋みが不得手な方にとっても飲みやすい飲料である。 The container-packed beverage of the present invention contains a sufficient amount of non-polymer catechins to exert a physiological effect, while bitterness and astringency peculiar to non-polymer catechins are alleviated, and bitterness and astringency are poor It is a drink that is easy to drink.
本発明で非重合体カテキン類とは、カテキン、ガロカテキン、カテキンガレート、ガロカテキンガレートなどの非エピ体カテキン、及びエピカテキン、エピガロカテキン、エピカテキンガレート、エピガロカテキンガレートなどのエピ体カテキンをあわせての総称である。なお、非重合体カテキン類の濃度は上記８種の合計量に基づいて定義される。 Non-polymer catechins in the present invention include non-epimeric catechins such as catechin, gallocatechin, catechin gallate, and gallocatechin gallate, and epi-catechins such as epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate. It is a collective term. In addition, the density | concentration of non-polymer catechin is defined based on the said 8 types total amount.
