Industrial relevance: Currently, there is a significant gap in the knowledge of the complex phenomena that
occurred during food freezing. This research develops a thermodynamic model which provides an accurate explanation
and a new insight of the main mechanisms involved in the meat freezing process. Moreover, this
model enables to leave a proof of the real structural impact that occurred in the muscular tissues, as a consequence
of the generation of ice crystals and agglomerates. In order to carry out this research, the thermal imaging
(TI) technique has been used. This is an innovative and emergent technology whose popularity and use at the
food industry has experienced a significant growth in recent years. The results obtained represent a starting
point for the future development of on-line cold chain monitoring systems in the food industry. The aim is no
other than to provide the necessary basis to meet current demands for food quality and safety.
