Resumen:
Transfer function approach to predict thermal histories of conductive foodstuffs when surroundings present different forcing functions during start-up of processes is reported. Food is assimilated to a delayed first-order system with unit gain and characterized by two parameters, the dead time (L) and the time constant (t). The comparison of experimental data with the proposed models for cooking as well as for retorting processes presented very satisfactory results when the equipment evolved as first-order, second-order and bounded integrating systems.
