Effect of sono-osmodehydration pretreatment on the mass transfer kinetics, freezing characteristics and quality attributes of frozen carrot (Daucus carota)

•Sono-osmodehydration was used to accelerate the freezing process.•A new exponential model was proposed for the prediction of WL and SG.•Dehydration pretreatment shortened the freezing time significantly.•High sonication duration resulted in structural damage, as confirmed by SEM.•Sono-osmodehydrati...
