Résumé

Recently, the use of ice containing trapped gaseous ozone, which provides the dual benefits of sterilization and deodorization, has gathered increased attention as a food cold storage method. As a method of efficiently trapping gaseous ozone in ice, the authors previously proposed the use of micro-bubbles with several tens of micro-meters in size. Since the process used to trap ozone micro-bubbles results in both ozone gas bubbles and dissolved ozone in the ice itself, both forms of ozone can be recovered and used effectively when the ice is melted. In this study, as the first step, gaseous oxygen is substituted for ozone, after which the suppression of oxygen micro-bubble coalescence, and decrease in the lifting speed of the bubbles caused by adding a small amount of surfactant, are investigated. Additionally, the influence of added surfactant on distribution of bubble size in ice, ice formation rate, mass of formed ice, and bubble content in ice are clarified.
