Monitoring of initial porosity and new pores formation during drying: A scientific debate and a technical challenge

By using X-ray microtomography (μ-CT) imaging, it has been possible to demonstrate that the initial empty spaces “initial porosity” of some fresh products is highly significant. The results of some mathematical simulations revealed that the two mechanisms are interrelated and therefore cannot be fully isolated and interpreted separately. This study opens a challenging scientific debate and an opportunity for finding a new approach for measuring/monitoring separately the two mechanisms during drying processes.
