Abstract
Method and apparatus for preferential heating of a material are based on exposing the material to high intensity, pulsed, non-ionizing electromagnetic radiation. The method can destroy microorganisms, sterilize packaging, or sterilize moist food. An embodiment uses microwave radiation with pulse duration of less than 0.1 second with an average power of at least 1 kW to sterilize open-ended metal can prior to packaging.
