A food storage device includes a housing defining an interior area accessible through a door coupled to the housing. The food storage device includes a vacuum pump in communication with the interior area for selectively removing air from the housing. A pressure activated switch is in communication with the vacuum pump and interior area for selectively actuating the pump. A humidifier is also positioned relative to the interior area for maintaining that area at a predetermined humidity level. A humidity sensor communicates with the humidifier for selectively actuating the humidifier to add moisture to the interior area so as to maintain a desired humidity level. The food storage includes a pressure equalizing valve in communication with the housing interior area and with an area external to the housing for equalizing a pressure inside the interior area with a pressure outside the housing.
