The Influence of Ultrasound and Cultivar Selection on the Biocompounds and Physicochemical Characteristics of Dried Blueberry (Vaccinium corymbosum L.) Snacks.

Hybrid drying was proposed as a novel approach in blueberry drying. Ultrasound application as a part of abovementioned drying technique is considered an efficient way of shortening drying time due to mass transfer intensification and the interaction with dehydrated tissue. However, no experiments studying the impact of ultrasound on various cultivars within one species were carried out. This study contributes to the understanding that appropriate cultivar selection in the production of ready-to-eat dried blueberry fruit is just as important as process parameters in obtaining an attractive product with a high level of natural bioactive compounds.
