Drying characteristics of mango slices using the Refractance Window™ technique

► Refractance Window technique has a high potential for the drying of fruit slices. ► Drying time is lower and the thermal damage is less for RW drying as compared to air drying. ► Drying time required for RW is reduced by a factor of 4-8 as compared to dry samples in a tray dryer. ► Water activity values sufficiently low to ensure the stability, were achieved by use of the RW.
