The central aim of the present work is devoted to study the effect on the earlier or Vigorous Bubbling step of the potato immersion frying process when a previous water heating treatment is applied to the potato samples. In such step, the occurrence of a Moving Front in the samples, from the external surface toward the symmetry center is experimentally observed. Such Moving Front separates two different zones: peripheral and central. Precisely, the influence of the water heating treatment of the potato samples on the dynamical behavior of the Moving Front is analyzed.
