Its low impact is justified by the fact that food remains at a temperature below the freezing-point during the process of sublimation, which tends to better preserve food quality. Despite that, the expensive equipment, high energy costs and long drying times are disadvantages which disable this technique to be applied as a routine basis procedure (Ratti, 2001). However, it can be considered as a drying control process in order to compare and evaluate the possible drying impact on food products.
