Development of W/O emulsion to form harmless ice slurry to human being

In order to form ice slurry in ice storage, W/O emulsion was made from water–oil mixture with a small amount of surfactant. And, it was proved that ice slurry could be formed even in a metal vessel, which is expected to improve ice formation rate, without ice adhesion to a cooling vessel wall because of a structural feature of the emulsion. In this paper, authors proposed application of ice slurry to cold storage of foods. In order to apply ice slurry to cold storage of foods, a new harmless ice slurry to human being was formed by cooling a new W/O emulsion made from tap water–edible oil mixture with a small amount of edible emulsifier. And, the fundamental characteristics and availability of new W/O emulsion-ice slurry formed were clarified. Finally, it was concluded that new harmless ice slurry to human being could be fully applied to cold storage of foods.
