RF oven was turned off once during the cooking of Fresh, M20 and
M20-G conditioned chicken breast meats, whereas during cooking of
M15 and M15-G conditioned chicken breast meat it was turned off
twice. A considerable amount of water evaporation was observed
during cooking experiments.
In several experiments, arcing occurred at the end of the process.
Despite developing the RF cooking protocol, arcing occurred either
on the container or the grid instead of the package. Even though arcing
was observed in some experiments, all the cooked chicken breast
meat packages were free of melting or any indication of burning.
Results showed that RF cooking of chicken breast meat had higher
heating rate than WB cooking. Average heating rate of chicken breast
meat was 2.67 °C/min during cooking in the RF oven, while it was
1.8 °C/min for WB cooking. Typical time–temperature graphs for RF
and WB cooking of M20 conditioned 1.36 kg chicken breast meat
are given in Fig. 2.
