Ozone has capability of sterilization and deodorization due to high oxidation power. And it is effective for conservation of perishable foods and purification of water. However, conservation of ozone is difficult because of resolving into oxygen. Recently, ice containing ozone is taken notice for the purpose of conserving ozone. In the present study, we investigated the influence of pressure of ozonized water on the concentration of ozone in ice and the shape of bubbles in ice. The higher pressure of water dissolved ozone, the smaller size of gas in ice. And the higher pressure of ozonized water, the larger concentration of ozone in ice.
