Nonthermal food processing techniques have been receiving considerable attention lately. They have the potential to maintain the qualityof the processed product while ensuring the food safety. Applicationof high voltage electric field (HVEF) is an important nonthermal processing technology and considerable research has been carried out inthe development of new applications (Kempkes & Tokuşoğlu, 2014;Muthukumaran, Orsat, Bajgai, & Raghavan, 2009). A major advantageof this technique is that there is no significant change in temperatureof food during processing. Hence, this method can be successfully applied to any temperature sensitive food matrix such as fruits and vegetables (Muthukumaran et al., 2009). Furthermore, the ability of thismethod to enhance heat and mass transfer could play an importantrole in food processing. The thermal and refrigeration processes in thefood sector often involve transferring energy between the productbeing treated and the air. These convective processes such as dryingor freezing require large air volumes, high air velocity and low or highambient temperature which can increase energy demands and consumption. The enhancement of the heat transfer at fluid-solid interfacesremains one of the crucial issues of these processes. For that purpose,the application of high voltage electric field appears a promising approach (Ahmedou & Havet, 2009).
