A refrigerator having an air pressure controllable storage container (100) is allowed to control air pressure of the storage container (100) to be temporarily lower than initial air pressure by hermetically sealing the storage container (100) and turning on a vacuum pump (200), so as to reduce dryness of vegetables stored in the storage container (100) and maintain optimal freshness of the vegetables. The refrigerator includes a storage container (100) configured to hermetically store fruits or vegetables therein, a vacuum pump (200) configured to suck internal air of the storage container(100), and a controller (300) configured to turn on the vacuum pump (200) such that internal air pressure of the storage container (100) is lower than an initial air pressure, and turn off the vacuum pump (200) such that the internal air pressure is restored to the initial air pressure.
