Ultrasonic Food Processing

Abstract

© The Royal Society of Chemistry 2018. Ultrasonic processing has wide applicability in the food industry. Ultrasonication can be used to improve conventional food processing unit operations by reducing energy and chemical requirements, thus offering a greener option. It can also be used to modify foods to create novel food products not possible using conventional food processing technologies. The unique mechanisms of ultrasound derive from both the physical interactions between the ultrasonic wave and the food medium and the phenomenon known as acoustic cavitation, which is the growth and collapse of bubbles in fluids. Food processing operations that can be enhanced by the physical effects o..
