2.5.2. Mathematical modeling of rehydration
The Page model was used to describe the water uptake kinetic of dehydrated pineapple during the rehydration process at
constant temperature. This empirical model is based on the following assumptions: water temperature is constant during
rehydration and initial moisture content is uniform. With the aim of explaining the water loss during singlelayer drying Eq. (5) was developed (Page, 1949):
