摘要：
Radio frequency (RF) energy is used to quickly heat the yolk portion of a shell egg. An anode and corresponding cathode are applied to each individual egg. As the egg is selectively and systematically rotated, RF energy and a stream of cooling fluid (preferably water) are simultaneously applied to the egg. This initiates pasteurization of the egg yolk while maintaining a low temperature in the heat-sensitive albumen (egg white) thus preventing denaturation of the albumen. Immediately after the RF yolk heating process, the egg is placed in a hot water bath designed to rapidly pasteurize the albumen as well as to minimize heat loss from the yolk and pasteurize any portion of the yolk that is not already pasteurized through the RF yolk heating process.
