ABSTRACTExperimental data are presented for water emission rates and temperature profiles of beef muscle that is heated in an especially constructed controlled environment oven in which air temperature, flow rate and humidity are continuously monitored and controlled at all times. Moisture loss rates and temperature rise in bovine semitendinosus muscle were measured for oven temperatures between 121°C and 204° C and for an air flow rate of 13.7 m3/hr in which fiber direction was parallel to the direction of the air flow. A qualitative model of heat and mass transfer is deduced that illustrates the interaction of heat and mass transfer during dry air roasting. The transport mechanisms known to be operative in the drying of rigid, nonproteinous porous media provide the basis for understanding the water emission behavior of cooking muscl
