Recebido em 2/12/08; aceito em 15/4/09; publicado na web em 26/8/09 MODELING AND SIMULATION OF THE OSMOTIC DEHYDRATION PROCESS OF PINEAPPLE'S PIECES USING THE FINITE ELEMENT METHOD. Water loss and sugar gain were modelling during the osmotic dehydration process of pieces of pineaplle. The transfer of solute to the fruit and the water to the solution was based on Fick's 2nd law. The three dimensional model was solved by the finite element method with the usage of the software COMSOL Multiphysics
