Effect of drying methods on the physical properties and microstructures of mango (Philippine 'Carabao' var.) powder

► We investigated the influence of different drying methods on the quality of mango powders. ► Refractance Window® (RW) drying, freeze drying, drum drying and spray drying were used in the study. ► The colors of RW- and freeze-dried mango powder were similar; drum- and spray-dried were inferior. ► No significant difference on solubility and hygroscopicity of RW- and freeze-dried mango powders. ► RW drying method produces superior quality mango powders and comparable to freeze drying process.
