Innovative methods of energy transfer

Energy is utilized in many forms for processing egg products and other foods. Energy in the form of heat has commonly been used to kill microorganisms and pasteurize eggs. Transfer of energy by convection and conduction is limited by the properties of the egg product. Energy transfer by radiation is being used to advantage in the development of innovative methods to kill or inactivate microorganisms. A review of the electromagnetic spectrum reveals underutilized forms of energy with unique properties. Specific frequencies and method of application are selected for their ability to focus energy toward the destruction of microorganisms and the production of safe food products for the public.
