2.2. Ohmic heating unit and procedures
Ohmic heating experiments were conducted in a laboratory
scale ohmic heating system consisting of a power supply, an
isolating variable transformer, power analyzer (Lutron DW-
6090) and a microprocessor board (Fig. 1.). The cell employed
was constructed from PTFE (Polytetrafluoroethylene or Teflon)
cylinder with an inner diameter of 2.5 cm, outer diameter
of 5 cm, and length of 0.15 cm and two removable stainless
steel electrodes with thickness of 0.2 cm.
