<p>Method and apparatus for preferential heating of a material are based on exposing the material to high intensity, pulsed, non-ionising 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 cans prior to packaging.</p> |
