Microwave technology for food applications

This chapter aims at introducing basic features of dielectric heating and to present the applications in the food industry. Based on a literature survey of recent works, many examples are given to highlight the main advantages of the microwave (MW) technology in food processing. The case of most processes involving heating is addressed. From another point of view, the environmental impacts, regulations, and safety aspects are discussed. Little data concerning the environmental impact of dielectric heating in the food industry are available. Therefore beyond assessing some particular points, a general methodology is presented which should be followed to obtain reliable results. Finally, some industrial examples are presented and future trends for the MW technique are given
