Osmotic dehydration kinetics of beetroot cubes in sucrose solution having different concentrations (30?Brix, 45?Brix and 60?Brix), solution temperature 35, 45 and 55 ?C, sample to solution ratio 1:4 were studied up to 240 min duration. For osmotic dehydration of beetroot in solution of sucrose the effect of all process parameter were significant at 5% level of significance on both water loss and solute gain (p<0. 05). The magnitude of ?-values revealed that osmotic solution concentration, temperature and time have positive effect on water loss and solute gain during osmotic dehydration. In case of solute gain, concentration has least effect as compared to temperature of osmotic solution and time of osmotic process. Among the different models applied (Peleg Model ,Penetration Model, Power Law Model, Magee Model, Azuara Model), Power Law Model best fitted to the experimental data for water loss and solute gain during osmotic dehydration.
