is quite susceptible to quality deterioration during conventional hot air (HA) drying[1-4]. Due to low thermal conductivity of the high sugar containing banana, heat transfer to the inner sections of foodstuffs in the falling rate period is limited during conventional heating, which renders low energy efficiency and lengthy drying time. Owing to the high sugar contents, banana drying normally requires high temperatures and prolonged drying time, which adversely affect its flavor, color, texture, nutrients, and rehydration capacity. As processors continue to grapple with lack of low-cost and energy efficient drying technology, the demand for the dried banana and co products shows a steadily increasing
