A refrigerator and a method to control the same are provided. The refrigerator includes a body (10) having a supercooling compartment (13), a cooling unit (20) to provide cool air to the supercooling compartment (13), an electromagnetic radiation sensor (45) to detect electromagnetic radiation emitted when a food placed in the supercooling compartment (13) begins to freeze, an energy supply (46) to apply energy to the food placed in the supercooling compartment (13) to prevent freezing of the food, and a controller to receive a detection signal from the electromagnetic radiation and then to activate the energy supply (46). Electromagnetic radiation emitted from each beverage in a supercooled state when the beverage begins to freeze is detected and energy is applied to the beverage according to the detection.
