IMPROVED CONDITIONS FOR MEASUREMENT OF THE SPECIFIC-HEAT CAPACITIES OF PURE TRIGLYCERIDES BY DIFFERENTIAL SCANNING CALORIMETRY

Reproducible specific heat capacities (C-p) of triglycerides can be ob tained by using heat-flux DSC under improved operating conditions. The improved operating parameters, such as the scanning rate, the sample mass and the atmosphere within the DSC chamber, were established via s tatistical analysis of the experimental data with trilaurin as a sampl e. The specific heat capacity results on trilaurin were compared with the values calculated by using estimation methods. The precision of th e specific heat capacity measured for trilaurin under these conditions was within +/-1%.
