Inverse procedures have been successfully used in several fields and scarcely applied in the field of food science/engineering. In addition, the experimental (direct) determination of thermophysical properties of foods in the freezing temperature range is tedious, complex and does not necessarily have the desired accuracy. The hypothesis is that designing just one simple and well-defined experiment (one-dimensional transient heat conduction) and implementing the appropriate mathematical and computational procedure, it will be possible to simultaneously obtain the thermal conductivity k(T) and apparent volumetric specific heat C(T) in the freezing temperature range (i.e., from the initial freezing point to -40 C).
