Synergism of ultrasound and microwave for food processing, preservation, and extraction

Nonchemical preservation techniques are gaining interest in food processing industry in terms of minimizing processing time, cost of processing, maximize quality, and guarantee the security of food products. Moreover, they are also preferred over thermal processing of foods for their power conservation role. Use of ultrasound and microwaves are already being engaged for different food applications from the past few decades. In this chapter, role of ultrasound and microwaves will be discussed in detail in terms of their recent innovative food applications. Moreover, this chapter will also highlight the synergistic effect of ultrasound and microwaves for their different roles in food processing industry; however, use of ultrasonic in combination with microwave has not yet been extensively explored.
