ABSTRACT
Microwave and radio frequency heating refer to the use of
electromagnetic waves of certain frequencies to generate
heat in a material. Microwaves are used in food processing
as well as preservation. For convenience, we can divide
microwave use into that for food processing (where the
goal typically is to obtain comparable quality but in
reduced time as compared to more conventional heating)
and food preservation (where the goal is to improve quality
while ensuring microbiological safety).
