Application and Research Progress of High-intensity Ultrasound Technique in Agricultural Products Processing Industry

The high-intensity ultrasound acting on a liquid medium can generates a series of unique physical and chemical effects, which had been ultrasound, widely applied in many industries. In this paper the author summarized the basic principle and the characteristics of highintensity ultrasound and the methods of producing ultrasound wave. The current situation of applications of high-intensity ultrasound in agriculture and the products processing industry was reviewed in terms of uhasround -reinforced separation, crystallization, deposition, atomization, emulsification, de-emulsification, dryness, dehydration, sterilization, thawing, washing and so on.
