Redox status in commercial bottled mineral water, ILOHAS, Mt. Fuji, Choju, Crystal Geyser, Volvic, Evian, Vittel, Perrier and Contrexville was studied. Among the 9 water, Choju and Perrier showed significantly larger DMPO-OH decay rate, k (min-1). Next, redox related correlation was studied with 9 water samples. A strong correlation between the hardness of water and the amount of residue after lyophilization of each water sample was demonstrated. Significant correlations were observed between X-ray-induced •OH generation and pH of the water sample. Another significant correlation was also observed between free radical-reducing ability and 1 minus the ratio of hardness/residue content (1-H/R value) of the sample water, which is a value indicating a ratio of mineral contents other than (Ca) and magnesium (Mg) in the water sample. No notable correlations were recognized among other factors, such as correlation between DMPO-OH generation C0int and residue weight, correlation between DMPO-OH decay rate and pH, and correlation between DMPO-OH decay rate and residue weight.
