PROBLEM TO BE SOLVED: To provide a tapioca-containing acidic beverage which can be distributed at normal temperature, capable of preventing the proliferation of bacteria caused by tapioca and the deterioration in texture and flavor and a manufacturing method thereof.SOLUTION: Gelatinous tapioca pieces sized at a pH less than 4.0 are added to an acidic beverage having a pH less than 4.0 to make a tapioca-containing beverage. A container is filled with the tapioca-containing beverage and sealed to make a bottled tapioca-containing beverage. The manufacturing method of a bottled tapioca-containing beverage includes the steps of: manufacturing gelatinous tapioca pieces which are sized, gelatinized, and adjusted to a pH less than 4.0 preparing a tapioca-containing beverage by adding the gelatinous tapioca pieces to an acidic beverage having a pH less than 4.0 sterilizing the tapioca-containing beverage at 65°C for 10 minutes or under equivalent or more severe conditions and cooling the tapioca-containing beverage and filling a sterilized container with the tapioca-containing beverage under sterile environment after the cooling step and sealing the container with a sterilized lid material.COPYRIGHT: (C)2015,JPO&INPIT【課題】酸性飲料、タピオカに起因する菌の繁殖、食感、フレーバー等のテクスチャーの劣化を防止した常温流通可能なタピオカ含有飲料及びその製造方法を提供する。【解決手段】pH4.0未満のサイズ化されたゲル状タピオカ片を、pH4.0未満の酸性飲料に添加したタピオカ含有飲料を容器に充填、密封した容器詰めタピオカ含有飲料とする。また、その製造方法は、サイズ化及びゲル化され、pH4.0未満に調整されたゲル状タピオカ片を得るゲル状タピオカ片製造工程、該ゲル状タピオカ片をpH4.0未満の酸性飲料に添加してタピオカ含有飲料を得るタピオカ含有飲料調製工程、該タピオカ含有飲料に、65℃、10分間又は同等以上の殺菌処理を行い、冷却を行う殺菌・冷却工程、並びに該冷却工程後に無菌環境下で該タピオカ含有飲料を殺菌済み容器に充填し、殺菌済み蓋材で密封する充填密封工程、を含む容器詰めタピオカ含有飲料の製造方法とする。【選択図】なし
