ABSTRACT
The aim of this work was to study the drying kinetics of fresh and osmotically treated papaya (Carica papaya L.) cubes. The osmotic treatment with 65 0Brix concentration of osmotic solution for 6 h was carried out in an incubator at constant temperature (60 0C) and agitation. The drying process was carried out in a fixed bed tray dryer at 60 0C. At the beginning of the drying process of fresh papaya, drying rate was influenced by air temperature till close to the equilibrium condition, the drying rate was affected by the impregnation of osmotic solution in to the product. The physicochemical changes in the papaya during osmotic treatment caused differences in the drying rate in the subsequent drying process when compared to fresh papaya cubes. The selected air temperature markedly influenced drying rate for fresh papaya samples at the beginning of drying. Close to the equillibrium condition, air temperature affected the drying rate.
