Özet:

Interest on novel thermal technologies has been steadily increased in recent years because of the some undesirable changes in the quality characteristics of foods and the low energy efficiency during conventional heating. Novel methods that meet customer expectations for minimally processed and high-quality products and enable high energy efficiency production can be alternative to conventional methods. In this review, induction heating and ohmic heating processes, which are novel electrical heating methods, are explained, and working principles and the differences between their application areas are discussed. The studies on the continuous system pipe line and cooking applications designed for both heating methods are presented. Based on the food processing systems established for similar purposes, the applicability of both heating methods to foods is compared, and their potential application areas are suggested.
