The variation of average thermal conductivity of coconut milk with temperature at various fat contents is shown in Fig. 1. The average values of thermal conductivity (3 replications) of coconut milk with 20–35% fat contents at different temperatures (60, 70, and 80 C) were 0.425–0.590 W/m C, with standard deviation in the range of 0.009–0.036 W/m C. The statistical testing showed that the fat content and temperature had a significant effect on thermal conductivity at a 95% confidence level. It was observed from Fig. 1 that thermal conductivity of coconut milk increased linearly with temperature but decreased linearly with fat content. In addition, the influence of fat content on thermal conductivity was stronger than that of temperature
