The samples dried purely convectively both in constant air temperature or stepwise
changing air temperature were characterized by significant shrinkage, hardening and discoloration (darkening), so the cherries dried
in this way were of poor quality. Sensory assessment of osmotically dehydrated cherries showed that those samples possessed
better texture, while maintaining the soft flesh and aroma. But, in
the case of color, the quality of cherries dried in variable air temperature preceded by osmosis was much better. However, the most attractive appearance had the samples dried with stepwise changing air temperature and preceded by ultrasonic assisted osmosis.
These cherries had pleasant sweetish smell and preserved soft flesh
much more than cherries pretreated only in sugar solution and
dried intermittently.
