The vigorous Bubbling step in the Potato Immersion Frying Process: Influence of a Previous water thermal treatment

Abstract

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.
