Osmotic dehydration kinetics of pineapple wedges using palm sugar

Osmotic dehydration kinetics of pineapple wedges was studied using palm sugar at different syrup concentration and temperature. Equilibrium kinetics were presented by defining equilibrium constants and nonequilibrium period of water loss and solid gain followed the model based on mass balance and zero order reaction kinetics. At constant temperature, the rate constants for both water and solids increased with increase in syrup concentration. At constant syrup concentration, the rate constants of water increased and the rate constants of solid decreased with the increase of temperature. Temperature had much more effect at high syrup concentration.
