A combined pretreatment of trehalose (0.5 %) and NaCl (0.5 %) solution was applied prior to drying eggplant to reduce shrinkage, browning and loss of polyphenols. Drying behaviour of eggplant slabs was experimentally examined in a convective dryer at temperatures of 50, 60 and 70 °C and at 2.3 m/s air velocity. Then the effects of pretreatment and drying temperature on the quality of the eggplant slabs in terms of microstructure, porosity, colour, total phenolic content, rehydration ratio and texture were investigated. It was noted that the pretreated eggplants (TR) dried more rapidly than the untreated ones (UTR) with a reduction of up to 1/4 of drying time. After drying at 50 and 60 °C, they showed no significant differences (p
