Abstract
A preferably self-contained food conservator system includes a vacuum compartment appropriate for storing baked goods, in which a negative pressure of about 10" Hg in maintained, preferably at about 60% relative humidity. The environment of the compartment preferably is feed-back-controlled by a microprocessor control. The microprocessor preferably can control vacuum, relative humidity, temperature, the amount of ozone introduced into the compartment to retard bacterial growth, as well as outgassing time cycles. A pushbutton type menu allows a user to input data used to control the microprocessor, and permit optimization of the compartment environment for the particular foodstuffs presently being stored.
