(57)< Abstract > It makes the metal sub- chlorate and the freezing two chlorine oxide content constituent which includes the proton Acid in the freezing water matrix. This, although the metal sub- chlorate of approximately 0.0005wt% - approximately 0.5wt% and pH of aqueous solution approximately are made small up to 1.8 - approximately 5.0, contains the proton Acid of sufficient concentration and at the same time makes by making the aqueous solution freeze which substantially does not contain two chlorine oxides. Two chlorine oxide concentration of the freezing two chlorine oxide content constituent is approximately 3ppm super, but before making freeze, two chlorine oxide concentration of the aqueous solution is under approximately 3ppm. Making the backing material contact, you use the freezing two chlorine oxide content constituent, in order to sterilize the backing material. As a suitable backing material, the food which intends the fact that the human or the animal eats, for example it can list the meat, the fish and the fowl.金属亜塩素酸塩及びプロトン酸を凍結水性マトリックス中に含む凍結二酸化塩素含有組成物とする。これは、約0.0005wt%~約0.5wt%の金属亜塩素酸塩及び水溶液のpHを約1.8~約5.0まで小さくするのに十分な濃度のプロトン酸を含有し且つ実質的に二酸化塩素を含有しない水溶液を凍結させることによって作る。凍結二酸化塩素含有組成物の二酸化塩素濃度は約3ppm超であるが、凍結させる前の水溶液の二酸化塩素濃度は約3ppm未満である。凍結二酸化塩素含有組成物は、基材に接触させて基材を殺菌するために使用する。適当な基材としては、人間又は動物が食べることを意図した食物、例えば肉、魚及び家禽を挙げることができる。
