During recent years, although a rapid increase of publications related to the possibilities of ultrasound application in drying technology has been observed, this has not resulted in this technique becoming available in everyday practice. The application of ultrasound into drying processes still remains at the experimental stage, what is more, the displayed results clearly indicate the necessity ... [Show full abstract] of their individual optimization and scrupulous dosage. To this day the potential benefits of US application seem to be attractive enough, to offset the costs and efforts of
the need to undertake meticulous research indispensable to determine the demands of specific raw materials which would potentially benefit from this process. In the article the current ‘state of art’ concerning the potential of ultrasound application in fruit and vegetable dehydration, related both for predrying and drying operations, are summarized.
