Resumen:
During the various stages of marketing, frozen food products are frequently subjected to changes in temperature which afect their quality.In the present work, a mathemtical model is developed to analyze the thermal behaviour of frozen meat subjected, under diferent insulationconditions, to thermal step functions and periodic fluctuations in temperature varying in amplitude and frequency.The heat transfer equation has been numerically solved, since it is asystem with physical properties that vary with the temperature, and fluctuating boundary conditions.At the same time, laboratory experiments were performed to verify that the mathematical model is applicable to one-dimensional and three dimensional heat transfer problems. The obtained results were cornpared with analytical solutions for the heat transfer equation, with constant coeficients, determining the temperature range for which it is pssible to use average values in the physical properties.
