Thermal properties of foods and agricultural materials.

Physical Properties of Foods pp Cite as. Since many stages in the processing and preservation of foods involve heat transfer, it is important to understand the thermal properties of foods. Thermal properties data are required in engineering and process design. An energy balance for a heating or cooling process cannot be made and the temperature profile within the material cannot be determined without knowing the thermal properties of the material. In this chapter, principles and measurement methods of thermal conductivity, specific heat, enthalpy, and thermal diffusivity are discussed. In addition, predicted models for thermal conductivity and specific heat are given. Unable to display preview.

  1. Thermal properties are necessary for the design and control of processes and storage facilities of food materials. This study proposes the measurement of thermal properties using easily constructed probes with specific heat capacity calculated, as opposed to the use of Differential Scanning Calorimeter DSC or other. Results showed thermal properties were within the range of 0. These results agree with reports for similar products studied using DSC and commercially available line heat source probes. Empirical models were developed for each property through linear multiple regressions. 🥴
