PROBLEM TO BE SOLVED: To provide a hot spring water without executing a heat treatment, a chemical treatment (addition of a hypochlorous acid or hydrogen peroxide solution, an electric field treatment to generate hypochlorous acid, or addition of silver ions or copper ions, or the like), an electromagnetic wave treatment (ultraviolet rays, gamma rays, or the like), or the like.SOLUTION: The present invention provides a pasteurized hot spring water obtained by pumping up hot spring water using a non-wetted pump, at a source temperature of 63°C or more within the past 24 hours, in a hot spring water source of 10 M or less underground, where the temperature is controlled by a temperature sensor, and filling it up to a sterilized sealed pack without bringing into contact with the open air, in which collected K ionic concentration is 20 mg/L or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】加熱処理、薬品処理(次亜塩素酸や過酸化水素水の添加や、次亜塩素酸を発生させる電界処理、あるいは銀イオンや銅イオンの添加など)、電磁波処理(紫外線、ガンマ線など)などの処理を行わない温泉水の提供。【解決手段】温度センサによって温度管理された地下10M以下の温泉水源泉において、過去24時間の源泉温度が63℃以上で、温泉水を非接液型ポンプを用いてポンプアップし、外気に触れさせることなく滅菌済み密封パックへ充填して採取されたKイオン濃度が20mg/L以上の低温殺菌温泉水。【選択図】図1
