PROBLEM TO BE SOLVED: To provide a cleaning method and a cleaning solution capable of holding a sterilization/fungicidal activity while decreasing a concentration of sodium hypochlorite.SOLUTION: A cleaning method includes cleaning a food as a cleaned object in flowing water by using chlorine bubble water which has a concentration of sodium hypochlorite of 20-80 ppm, and contains fine bubbles. In the food cleaning method, a percentage content of fine bubbles is 0.5-2.0% in a volume fraction in the chlorine bubble water, and a concentration of sodium hypochlorite is 20-80 ppm.EFFECT: A food as a cleaned object is cleaned in flowing water by using fine bubble-containing chlorine bubble water so as to hold a sterilization/fungicidal activity while decreasing a concentration of sodium hypochlorite, and retain freshness without spoiling the flavor of the food.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】次亜塩素酸ナトリウムの濃度を低下させつつ、除菌・殺菌力を保持できる洗浄方法及び洗浄溶液の提供。【解決手段】次亜塩素酸ナトリウムの濃度が20~80ppmであり、微細気泡を含有する塩素気泡水を用いて、洗浄対象である食品を流水洗浄する洗浄方法。該塩素気泡水において、微細気泡の含有率は、体積分率で0.5~2.0%であり、次亜塩素酸ナトリウムの濃度は20~80ppmである食品の洗浄方法。【効果】微細気泡を含有する塩素気泡水を用いて、洗浄対象である食品を流水洗浄することにより、次亜塩素酸ナトリウムの濃度を低下させつつ、除菌・殺菌力を保持できるため、食品の風味を損ねず、鮮度を維持できる。【選択図】図2
