on average,as well as the sugar gain by 3 [% wb]. Thus, drying with previous
UDOD clearly increases the efficiency of total dehydration. It means
that, ultrasonic waves influence both the dewatering kinetics and
the physical properties of cherries, especially the structure of tissues induced by the so called “sponge effect” [28]. Moreover, this
phenomenon accelerates diffusion of moisture from the dried biomaterial to the surrounding hot air and reduces total drying time
by about 1 h, compared with hot air drying without OD.
