Ultrasound

Ultrasound is an emerging technology in food processing and has demonstrated definite advantages. In this process, during contact with a liquid, ultrasonic waves generate expansion and compression zones, creating thousands of bubbles. As a result, the temperature and pressure inside the medium become very high. This physical phenomenon is referred to as Cavitation and is the factor responsible for the consequent inactivation of microorganisms.
