The highest drop was observed during the first 100 min of drying, when the moisture content decreased from
6.22 ± 0.02 kg H2O kg1 DM to 4.85 ± 0.02 kg H2O kg1 DM. In case of waxy skinned blueberries, such low temperature did not allow to maintain high moisture gradient between inner and outer parts of blueberries resulting in significantly lower drying rates than in other drying processes used in the study.
