摘要： Conventional food treatment processes utilized for food preservation generally involve heat treatment and usually result in some degree of thermal damage. A process has been developed for the non-thermal treatment of liquid food products which results in a significant reduction in the microbial population, thus reducing spoilage and extending shelf life. The novel process involves the rapid application of electromagnetic energy (EME), such as microwave or radio frequency energy, and the simultaneous removal of any thermal energy which may be generated by the process through the use of circulating cooling medium and an efficient heat exchanger.
