The material is heated to a predetermined temperature for a predetermined time in order to achieve a food product characterized by a preselected refrigerated shelf life of from about two weeks to about forty-two weeks. The food product may be packaged prior to the microwave exposure so as to sterilize the packaging and decrease product loss.

The relative position between the set of heating lamps and the wafer is adjusted so that the wafer center is at the position with local mean heat flux from lamps between the most inner lamp subset and its adjacent lamp subset. Followed by adjusting the heating powers, either or both of the wafer and the set of heating lamps are rotated respect to the center of the wafer, so as to improve uniformity of the heat flux distribution on the heated object.
