(4) reviewed the application of microwave heating in
food processing with reference to the advantages and limitations
for a range of food processing operations.
Microwave penetration depths within a product are determined
by the electrical and physical properties, heating patterns,
microbial inactivation, and safety (5) and can vary significantly
with chemical composition, product temperature,
and the frequency at which the microwave operates. Industrial
microwave systems are available in both batch and continuous
design configurations and use magnetrons that develop either
915 or 2450 MHz (6). Lassen and Ovesen (7) reviewed the effects
