Thermophysical properties of coconut milk Original Research Article

Thermal conductivity and specific heat of coconut milk were measured by a thermal conductivity probe apparatus and a differential scanning calorimeter (DSC), respectively. Thermal diffusivity of coconut milk was then calculated from experimental results of thermal conductivity, specific heat, and density. It was found that thermal conductivity, specific heat, density, and thermal diffusivity of coconut milk samples with 20–35% fat content at 60–80 °C were in the range of 0.425–0.590 W/m °C, 3.277–3.711 kJ/kg °C, 969.00–983.05 kg/m3, and 1.325–1.634 × 10−7 m2/s, respectively. The empirical models for each property as a function of fat content and temperature were obtained.
