摘要

We exploit prediction capabilities of the moving-boundary model for food isothermal drying proposed in Adrover et al. (2019). We apply the model to two different sets of literature experimental data resulting from the air-drying process of eggplant cylinders (two-dimensional problem) and potatoes slices (three-dimensional problem). These two food materials, both exhibiting non-ideal shrinkage, are characterized by very different "calibration curves", i.e. different behaviours of volume reduction V/V-0 as a function of the resealed moisture content X/X-0. The purpose is twofold: to validate the model for different food materials and different sample geometries and to propose a simpler numerical approach for estimating the shrinkage factor, thus bypassing too lengthy analytical calculations and developing a general method that can be easily applied to any sample geometry and any food material characterized by a non-linear calibration curve.
