Abstract:
The present study was aimed at determining the thermal properties, namely, thermal conductivity, specific heat, and thermal diffusivity, of minced chicken meat at a moisture content range of 72 to 81 percent wet basis and a temperature range of 40o to 85oC. Thermal conductivity and specific heat were measured using the line heat source probe method and differential scanning calorimetry (DSC), respectively. Thermal diffusivity was calculated as a mathematical function of these properties. The results showed that the thermal conductivity of minced chicken meat ranged from 0.553 to 0.700 W m-1 oC-1, the specific heat of the meat varied from 3.589 to 3.935 kJ kg-1 oC-1, and the thermal diffusivity of the meat varied from 1.37 x 10-7 to 1.71 x 10-7 m2 s-1. Additionally, thermal conductivity, specific heat, and thermal diffusivity of minced chicken meat were found to increase linearly with moisture content and temperature. Minced chicken meat density was found to increase with an increase in moisture content and decreased as temperatures increased. An empirical correlation based on the moisture content and temperature was developed to predict the thermal properties of minced chicken meat during cooking. The correlation from the literature was found to accurately predict the thermal properties of minced chicken meat within the moisture content and temperature ranges of interest.
