Research Abstract

Methods We studied antibacterial effect of disinfectant alkaline ionized water and preservative effect of disinfectant alkaline ionized water on foods. Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilus and Bacillus cereus were added in tap or disinfectant alkaline ionized water and a number of residual living bacteria measured till two hours later. Tofu was maden using tap or disinfectant alkaline ionized water and many kinds of foods were added in tap or disinfectant alkaline ionized water to examine preservative effect of disinfectant alkaline ionized water on foods.
Results Disinfectant alkaline ionized water showed high antibacterial effect on Escherichia coli and Pseudomonas aeruginosa but did not show the same effect on Bacillus subtilus and Bacillus cereus. It seems that disinfectant alkaline ionized water is ineffective on spore bacteria. Disinfectant alkaline ionized water reduced the increase of growth of bacteria in tonyu before heating, but did not reduce that of bacteria in tonyu after heating. But the increase of growth of bacteria in tofu stored in disinfectant alkaline ionized water was reduced. Disinfectant alkaline ionized water prolonged the preservation term of mugicha, mehijiki, kezuribushi and tororokonbu, but did not prolonged the preservation term of uncocked chinese noodle, prawn, coffee, consomme, soysoup, whipped cream. jelly, drywakame and nibosi.
