The experiment was conducted to determine the drying rate, moisture content of osmo-dried papaya slice. Drying of papaya slices in a hot air oven dryer takes only 660 minutes for drying from an initial moisture content of 89% (wb) to a final moisture content of , , and (db) of 55 oBrix and the final moisture content were recorded of 65 oBrix that , , and (db) for T1, T2, T3 and T4 samples. The drying temperature is the main factor controlling the rate of drying. It is an important parameter for internal water transfer in the product. | Effect of hot air oven drying on the moisture kinetics and drying rate of osmo-dried papaya (Carica papaya L.) slices
