The application of ultrasound in food production processes is a field of growing interest for food manufacturers. In contrast to low intensity ultrasound (intensities < 1 W/cm²), which can be used for non-destructive testing and imaging, power ultrasound (intensities > 5 W/cm²) causes material alteration and can be used for the improvement of versatile processes in the food industry. Ultrasonic waves are compression waves that mechanically interact with the product under sonication. Cyclic compressions and rarefactions can influence cell structure. At high pressure amplitudes power ultrasound causes cavitation, the growth and implosion of gas bubbles, which is accompanied by pressure and temperature peaks and homogenizes and stabilizes disperse systems. Hielscher Ultrasonics and researchers from the Department of Food Biotechnology and Food Process Engineering from the Technical University of Berlin investigated of the positive effects of ultrasound to improve quality, stability and taste of smoothies; blended and chilled beverages made of fruit and vegetable juices and purees.
