Résumé

Water sorption characteristics of five tropical fruits, namely, banana, papaya, pineapple, mango and jackfruit were investigated. Fresh samples were used for the determination of desorption isotherms whereas, freeze-dried samples were used for the evaluation of resorption isotherms. Experiments were conducted at ten different water activity levels (0.11-0.97) at 30°C. Saturated salt solutions in desiccators were used to create different atmosphere of constant water activities. Desorption and resorption data are fitted with the GAB (Guggenheim-Anderson-de Boer) model. The model predicts well the experimental results, and the monolayer moisture content values for all the fruits are calculated from the model parameter.
