An Overview of Ultrasonic Technology and Its Applications in Food Processing, Preservation and Quality Control

Ultrasound is one of the emerging technologies that were developed to minimize processing,
maximize quality and ensure the safety of food products. In recent years, ultrasound technology has
been used as an alternative processing option to conventional thermal approaches. Although
Ultrasonication methods have been used for years in research and diagnostics, major advances have
been made in the last decade. The applications for which high power ultrasound can be used range
from existing processes that are enhanced by the retrofitting of high power ultrasonic technology, to
the development of processes up to now not possible with conventional energy sources. The present
paper reviews the generation, principle mechanism, properties, process parameters, applications,
merits and demerits and future trends of the ultrasound technology in the food processing.
