A novel technique of Dynamic Neutron Radiography (DNR) was applied for identifying and visualizing the dewatering paths and patterns in apple slices at three thicknesses, to the best of our belief for the first time in this field. By analyzing the DNR images obtained, the iso‐distribution of water (dewatering paths) and fractals (patterns) were obtained. Having the images geometrically calibrated and bileveled, the surface changes of apple slices were described by an exponential model in the course of a dewatering study period of 1500 min, with the velocity of the shrinkage of surfaces being estimated.
