Summary: The present invention relates to a cost effective, non thermal pasteurization system that effectively treats liquid foods using radio frequency electric fields "RFEFs". One embodiment of the system operates by flowing liquid food products through a treatment chamber or a series of treatment chambers wherein the liquid food is exposed to high strength, uniform RFEFs for very short periods of time (i.e. less than 1 second). The treatment chamber is designed to apply a uniform and concentrated RFEF to the liquid food being treated. The system can be designed to incorporate recycling to increase the effectiveness. Suitable field strengths, treatment times and frequencies are provided. Patent Status: Patent Application Filed on February 22, 2005.
