The results acquired regarding the freezing of pork tenderloin under the presence of microwaves revealed that, apart from controlling the nucleation temperature, the final quality of the frozen product also may be improved as the damage of the meat mcrostructure was significantly improved under the tested conditions. This first achievement demonstrates an effectiveness of the microwave radiation in controlling ice crystal size. Further investigation is needed in the direction of the underlying heat transfer phenomena of the process and application of this innovative freezing process to other food systems would be beneficial.
