When materials contain sufficient water and electrolytes to allow the passage of electric current, Ohmic Heating (OH) can be used to generate heat within the product. OH (also referred to as Joule heating, electroheating, and electroconductive heating) is defined as a process wherein electric current (usually alternating) is passed through materials with the primary purpose of heating them. The heating occurs in the form of internal energy transformation (from electric to thermal) within the material (Sastry & Barach, 2000). Therefore, OH can be seen as an internal thermal energy generation technology,and not only as a thermal energy transfer, meaning that it does not depend on heat transfer either through a solid-liquid interface or inside a solid in a two-phase system.
