The experiment includes five pre-drying treatments namely, slicing, peeling, steaming,blanching with polythene sheet and boiling, and three drying methods namely, solar drying, microwave drying and open sundrying. Among pre-drying treatments, steaming recorded the lowest drying time, the lowest final moisture content andblanching with polythene sheet recorded the highest dry recovery. Whereas among the drying methods, microwave dryingrecorded the least drying time and the highest dry recovery and solar drying recorded the lowest final moisture content.
