PROBLEM TO BE SOLVED: To generate nuclear magnetic resonance over a vast range in a storage of a quick freezing refrigerator which utilizes nuclear magnetic resonance. SOLUTION: The refrigerator 40 is provided with a pair of varying magnetic field generating means 41 for generating a variable magnetic field in which magnetic force varies, an electromagnetic wave generating means 42 for radiating electromagnetic waves of a given frequency toward food 44 from a direction right angle to the magnetic force line of the variable magnetic field, and a refrigerating means 43 for cooling inside of the refrigerator 40. Nuclear magnetic resonance is generated in a hydrogen nucleus by the variable magnetic fields and the electromagnetic waves to lower the freezing temperature of the water molecules contained in the food 44. Utilizing such a phenomenon, the food 44 is allowed to freeze at a temperature which is lower than the normal freezing temperature of the food 44. Thus, nuclear magnetic resonance is generated over a vast range in the storage, enabling refrigeration of the food 44 without destroying its cell membranes. Accordingly, when the food 44 is thawed, the cell membranes can be restored to have the pre-refrigeration conditions. In this way, food as refrigerated fresh can be served.
