| Abstract;Strong acidic electrolyzed water(SAW) has unique characteristics such as high positive oxidation-reduction, strong acidity, high concentration of dissolved oxygen and strong bactericidal activity. The bactercidal effect is considered to be due to hypochlorous acid(HOCl) and residual chlorine contained in SAW. It is well-known that the residual chlorine in sodium hypochlorite solution(NaOCl) decreases when mixed with organic substances. But a detailed analysis of the reaction of SAW with organic substances has not been done. It this research, we examined the effect or organic substances contained in cabbage juice on SAW, comparing SAW and NaOCl solution. As a result, it was suggested that 85% of the residual chlorine in NaOCl and SAW was consumed by nitrogenous compounds and 15% of it was consumed by other substances such as kinds of polyphenol and L-ascorbic acid. Then we measured the rates of concentration of free and combined chlorine when the residual chlorine in SAW and NaOCl reacted with ammonia. These results indicate that the characteristics of SAW are mainly due to the residual chlorine and strong acidity. (author abst.) |
