Ohmic heating has different names and each names shows its principle of heating – Joule heating OR Electric resistance heating OR Direct electric resistance heating OR Electroheating OR Electroconductive heating. In ohmic heating process, alternating electric current is passed through food material; heat is internally generated within the material owing to its resistance to the applied electrical current. Unlike conventional heating where heat transfer occurs from a heated surface to the product interior by means of convection and conduction, Ohmic heating has inside–outside heat transfer pattern.
