Exploiting maltodextrin and whey protein isolate macromolecules as carriers for the development of freeze dried honey powder

This study was aimed at development of freeze drying powders from three types of honeys viz. Robinia pseudoacacia (RSA), Plectranthus rugosus (PR) and multifloral honey (MF) from Kashmir Himalayas of India using whey protein isolate (WPI) and maltodextrin (MD) as drying carriers. The powders were evaluated for physical, morphological and structural characterization. Results exhibited that powders with MD as drying carrier showed significantly higher water activity (aw), hygroscopicity, loose bed porosity (ɛL), tapped bed porosity (ɛT) and mean particle diameter (p
