【産業上の利用分野】
本発明は、耐酸性、耐塩性、耐熱性に優れた油脂含有水溶性組成物およびこれを含有する飲食品に関するものである。
【0002】
【従来の技術】
飲食品、特に飲料では、油脂をその飲料に添加配合する場合、様々な添加物を配合し、熱殺菌処理をするため、耐酸性、耐塩性、耐熱性に優れ、かつ、長期間保存してもクリーミングを生じたり、油脂が分離することなく、均一な乳化もしくは可溶化状態を保つことが望まれている。
このような飲食品を開発するために、これまでに種々の検討がなされてきた。
例えば、ジェランガムを用いてゲル化する方法(特開昭62−125850号公報)、ポリアミンを含むカプセル壁を有するマイクロカプセルを用いる方法(特開昭63−119845号公報)、乳清蛋白質の加水分解物を含有させる方法(特開平2−257838号公報)などが提案されている。
