Abstract  

In this paper, the moisture loss mechanism in biological tissue of apples was experimentally investigated in order to understand this mechanism and hence to extend their shelf life. An image conversion procedure, based on the use of image processing and AlgoLab Photo Vector softwares, was developed in order to characterise physically the internal porous structure of apples from the core to the skin. Several geometrical and physical parameters of the restructured porous media (porosity, fractal dimension, tortuosity, capillary pressure, permeability) were determined, and a comparison between their trends was carried out and analysed. Besides, a moisture loss model was established and discussed.
