Abstract
Description
本発明は非重合体カテキンガレート体類を高濃度含有し、色相変化の抑制された容器詰飲料及びその製造法に関する。 (4) The present invention relates to a packaged beverage containing a high concentration of non-polymer catechin gallates and suppressing a change in hue, and a method for producing the same.
カテキン類の効果としては、コレステロール上昇抑制作用やαアミラーゼ活性阻害作用などが報告されている（例えば、特許文献１、２参照）。このような生理効果を発現させるためには、成人一日あたり４〜５杯のお茶を飲むことが必要であることから、より簡便に大量のカテキン類を摂取するために、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。この方法の一つとして、緑茶抽出物の濃縮物（例えば、特許文献３参照）などを利用して、カテキン類を飲料に溶解状態で添加する方法がある。 As the effects of catechins, an effect of suppressing cholesterol elevation and an effect of inhibiting α-amylase activity have been reported (for example, see Patent Documents 1 and 2). In order to express such physiological effects, it is necessary to drink 4 to 5 cups of tea per day for an adult. Therefore, in order to more easily ingest a large amount of catechins, catechins are added to the beverage. There has been a demand for a technique of blending high concentrations. As one of the methods, there is a method of adding a catechin to a beverage in a dissolved state using a concentrate of a green tea extract (for example, see Patent Document 3).
一方、非重合体カテキン類のなかでもガロカテキンガレートやエピガロカテキンガレートなどのいわゆる非重合体カテキンガレート体類は特に生理活性が高いことが知られており、飲食物や健康食品分野で抗アレルギー剤や脳機能活性化剤などの提案がなされている（例えば、特許文献４、５参照）。しかしながら非重合体カテキンガレート体類はその生理効果を高める目的で高純度製剤化される製造過程において酸、アルカリ、熱、溶剤等の多くの精製プロセスを経るために、緑茶抽出物でありながら独特の色調を呈する結果となり、高い生理効果がある反面、飲料処方上その使いこなしが難しいという大きな問題を抱えている。従ってこれを高濃度配合した飲料では長期保存時や加熱殺菌時のpH変化に伴う外観の安定性が特に重要な課題となってくる。
本発明の目的は非重合体カテキンガレート体類を高濃度に含有し、かつ色相変化を抑制した容器詰飲料を提供することにある。 目的 An object of the present invention is to provide a packaged beverage containing a non-polymer catechin gallate at a high concentration and suppressing a change in hue.
本発明者は、高濃度の非重合体カテキンガレート体類を含有する容器詰飲料の色相変化を抑制すべく検討した結果、アスコルビン酸又はアスコルビン酸金属塩を一定量配合してpHを４．５〜７にすることによって、長期保存時や加熱殺菌によって通常想定されうるpH変化においても色相の変化を来し難い容器詰飲料が得られることを見出した。 The present inventor has studied to suppress a change in hue of a packaged beverage containing a high concentration of a non-polymer catechin gallate derivative, and as a result, a certain amount of ascorbic acid or a metal salt of ascorbic acid is blended to adjust the pH to 4.5. It has been found that by setting the value to ７7, a packaged beverage that does not easily change in hue even during a long-term storage or a pH change that can be normally assumed by heat sterilization can be obtained.

実施例１〜４、比較例１〜４
テアフラン９０Ｓ（伊藤園社製）をそれぞれ０．２〜０．４重量％になるようにイオン交換水に溶かした。次に適当量のアスコルビン酸とアスコルビン酸ナトリウムでpHを調整した飲料を調製した。次に各飲料のＬ値（明るさ）とｂ値（黄色）を色差計（ｃｏｌｏｒ Ｍｅｔｅｒ ＺＥ２０００、ＮＩＰＰＯＮ ＤＥＮＳＨＯＫＵ社製）で測定した。その結果を表１に示す。
Examples 1-4, Comparative Examples 1-4
Theafuran 90S (manufactured by ITO EN Co., Ltd.) was dissolved in ion-exchanged water so as to be 0.2 to 0.4% by weight. Next, a beverage whose pH was adjusted with an appropriate amount of ascorbic acid and sodium ascorbate was prepared. Next, the L value (brightness) and the b value (yellow) of each beverage were measured with a color difference meter (color Meter ZE2000, manufactured by NIPPON DENSHOKU). Table 1 shows the results.
試験の結果、非重合体カテキンガレート体類の多い、精製度の極めて高い緑茶抽出物においては、pHに依存する色の変化がより中性領域の方が安定であることが判った。つまり容器詰飲料としての長期保存安定性及び殺菌処理前後の組成変化を鑑みた場合、保存時または殺菌処理時のpH変化による飲料の外観への影響を最小限に抑えるためにはpH４．５〜７が好ましいことが判った。 As a result of the test, it was found that in the highly purified green tea extract containing many non-polymer catechin gallates, the pH-dependent color change was more stable in the neutral region. In other words, considering the long-term storage stability as a packaged beverage and the composition change before and after the sterilization treatment, in order to minimize the influence on the appearance of the beverage due to the pH change during storage or sterilization treatment, the pH is 4.5 to 4.5. 7 was found to be preferred.
