Many papers concerning various drying methods of soft tissue
fruits can be found,
but there is not much literature on the use of
ultrasound assisted osmotic dehydration pretreatment before step
wise (intermittent) air drying applied to sour cherries. The aim of this study was to examine the effect of combined ultrasonic assisted osmosis with intermittent convective drying on drying kinetics and
selected quality indicators like color and water activity.
