Abstract
System and method for preserving food. Embodiments of the system include a food compartment to store food and a user interface configured to receive user input relating to the preservation of the food stored. The system also includes a humidity sensor configured to sense a humidity level, an ozone generator configured to generate ozone gas, an ozone sensor configured to sense an ozone level and a gas sensor configured to sense a level of residual gases inside the food compartment. The system further includes a controller, responsive to the user interface, the humidity sensor, the ozone sensor and the gas sensor. In one embodiment, the controller preserves the food stored in the food compartment as a function of the user input, the humidity level, the ozone level, the residual gas level and as a function of a type of the food stored in the food compartment.
