<P>PROBLEM TO BE SOLVED: To inform a user when the user is going to store food unsuitable for refrigeration or freezing. <P>SOLUTION: A reader 4 provided at a refrigerator 2 reads information on a radio IC tag 6 attached to the food 5, analyzes read information, and informs the user if the food 5 corresponds to food unsuitable for refrigeration or freezing such as vegetables and fruit causing low temperature trouble stored in a storage means. The user is thereby prevented from carrying out an erroneous preservation method, and if the user desires to eat the food after cooling it, it is cooled as it is, and the user is informed when it is cooled properly. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
