Process for preparing food in the package

Claim 1

A process of baking foods in flexible containers comprising providing a flexible package that is a barrier to microorganisms and is capable of withstanding baking temperatures, placing the farinaceous food product in the package, sealing the package to provide a filled package, maintaining a vent opening in said flexible package to allow the escape of steam and gas during baking, plaing the package in a baking oven and exposing it to heat for a sufficient period of time to bake or to cook the food product and generate steam to fill the space within the package, excess steam being allowed to escape through the vent opening, providing a source of sterile air free from viable mold spores, allowing said package to cool and inspire said sterile air through the vent opening as steam within said package condenses, the amount of sterile air inspired being in an amount sufficient to prevent the package from being crushed by the atmospheric pressure when the vapor condenses within the package, thereafter sealing the vent opening to completely seal the package to contain said condensed moisture generated during baking and the inspired sterile air whereby a package of bakery goods is provided which is free from mold for a period of 120 days storage at room temperature.
