Abstract: <P>PROBLEM TO BE SOLVED: To provide ice for preserving/cooling food enhanced in its usability in view of safety, costs and environment by solving such problem that conventional ice for preserving/cooling food obtained by dissolving a chlorine type sterilant in water and freezing the solution requires for contrivance in an ice-making process because the chlorine type sterilant (hypochlorous acid) is rapidly decomposed, or water molten from ice has bad influence on the environment when discharged into the river.  <P>SOLUTION: The ice for preserving/cooling food is obtained by freezing water where a tannic acid is dissolved. This process makes the ice exert its original function to keep the freshness of food due to its low temperature, and also it has no anxiety about being regarded as a pollution source even when melted because the tannic acid is dissolved in the water itself to obtain the ice and thereby the ingredients of the water melted from the ice prevents deterioration of the food because the tannic acid is dissolved in the water, and thereby it has no anxiety about causing environmental destruction even when discharging the tannic acid-containing water as it is into the river. The tannic acid is easily soluble into water and hard to be decomposed so as to be easily produced only by addition of the tannic acid to freeze the tannic acid-mixed water to make ice.  <P>COPYRIGHT: (C)2004,JPO
