The objectives of this work were, therefore, to provide information on comparison of rehydration characteristics of five freezedried tropical fruits, namely, pineapple, mango, guava, acerola and papaya, to test different mathematical models for a proper description of the rehydration kinetics as well as to assess rehydration indices related to water uptake and loss of solubles. Glass transition temperatures of the freeze-dried fruits were also determined in order to verify possible influence of rehydration-induced deterioration in highly porous matrices on the rate and degree of restoration of water lost during drying.
