The RF oven used was a custom built 50 X system built by CTech Innovation (Chester, UK) using a low power (0.6 kW) RF generator (Model No. RFG 600-27, Coaxial Power System Ltd., Spectrum House, Finmere Road, Eastbourne, East Sussex, UK) and a
complementary automatic impedance matching network and controller (Model No. AMN 600-27) at a frequency of 27.12 MHz. The
boxed meat was placed at the centre of the bottom electrode and
tempered at 500 W for 11 min or thawed at 400 W non-continuously (20 min RF power on, 10 min off followed by 15 min on).
Meat blocks of these dimensions have been used in previous studies and their temperature profiles following defrosting have been
precisely established
