PROBLEM TO BE SOLVED: To provide a chlorine dioxide generator that allows both of chlorine dioxide and a flavor to effectively work, without the flavor to be decomposed by the chlorine dioxide.SOLUTION: A chlorine dioxide generator contains chlorite, an oxidizing agent and a specific flavor that does not react with chlorine dioxide. The chlorite, oxidizing agent, and flavor are contained in a mass ratio of the oxidizing agent 0.01-10 and the flavor 0.01-5 to the chlorite 1.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】香料が二酸化塩素によって分解されることなく、二酸化塩素および香料の両方が有効に作用する二酸化塩素発生剤を提供する。【解決手段】二酸化塩素発生剤は、亜塩素酸塩と酸化剤と二酸化塩素と反応しない特定の香料とを含み、前記亜塩素酸塩、酸化剤および香料が、質量で、亜塩素酸塩1に対して酸化剤が0.01~10、香料が0.01~5の割合で配合されている【選択図】図1
