Ultrasound has attracted considerable interest in food science and technology due to
its promising effects in food processing and preservation. As one of the advanced food
technologies it can be applied to develop gentle but targeted processes to improve the
quality and safety of processed foods and offers the potential for improving existing
processes as well as for developing new process options. There are an increasing number
of industrial processes that employ power ultrasound as a processing aid including
the mixing materials; foam formation or destruction; agglomeration and precipitation of
airborne powders; the improvement in efficiency of filtration, drying and extraction
techniques in solid materials and the enhanced extraction of valuable compounds from
vegetables and food products. Ultrasonic can be a specialized and versatile technology
with numerous applications in food processing. Ultrasonic processing is still in its infancy
and requires a great deal of future research in order to develop the technology on
an industrial scale, and to more fully elucidate the effect of ultrasound on the properties
of foods.
