ConclusionThis
study investigated the drying of sliced durian flesh to produce oilfree durian chips using microwave vacuum (MWVC),combined microwave-hot air (MWHA) and hot air (HA) drying treatments. The results showed that the drying rates ofthe combined microwave techniques were higher than for the HA method, and these rates increased with microwave power level, leading to shorter drying times. The drying rate of thedurian chips in the MWVC also increased at lower pressure levels in the same way as for the microwave power. MWHA drying provided higher drying rates than MWVC drying.
