Description In the present investigation, far infrared (FIR) assisted refractance window (RW) drying (FIR+RW) of apple slices (2 and 5 mm) was evaluated in comparison with RW and hot air (HA). FIR+RW reduced drying time by 50 and 69% compared to RW and HA, respectively. Also, FIR+RW drying retained a significantly higher amount of phenolics, flavonoids, ascorbic acid, and antioxidant activity, as compared to HA. Increase in FIR temperature from 50 to 60 °C reduced drying time by 10–19% without having any deleterious effect on quality. Colour, flavour, and microstructure of FIR+RW dried slices were comparable to that of RW. Nearly 46% saving in energy consumption was observed for FIR+RW drying compared to HA. Results suggested that FIR+RW drying can be explored as a potential technique for drying of fruits in a shorter time, with better retention of flavour, nutrients and also enhance energy efficiency.
