The Triglyceride Property Calculator (TPC) is a software implementation of the semi-empirical model developed by Leendert Wesdorp as his Ph.D. thesis (Wesdorp L (1990). Liquid-multiple solid phase equilibria in fats: theory and experiments. Doctoral Dissertation. TU Delft, Delft University of Technology). We revisited Wesdorp's work in 2017 (Moorthy et al. 2017. Estimating Thermodynamic Properties of Pure Triglyceride Systems Using the Triglyceride Property Calculator. J Am Oil Chem Soc (2017) 94:187-199), where we also developed this app. Rigorous testing of the calculator made apparent that the model is capable of estimating enthalpies of fusion with measurable success for both saturated and unsaturated triglycerides of all polymorphs, and particularly strong predictions of measurements for β saturated triglycerides. Testing also made evident that the current implementation of the Triglyceride Property Calculator has suspect value in predicting melting temperatures of triglycerides, often generating predictions that are physically unlikely. In spite of these issues, the TPC is an important preliminary advance in what will surely be a continued effort to generate quality estimates of thermodynamic properties for pure triglycerides. With continued, rigorous development, we expect to eventually build a tool, or tools, capable of estimating thermodynamic properties of mixed systems of multiple liquid and solid triglycerides; a development of significant value to scientists and engineers investigating naturally occurring fats and oils.

We offer range of analytical services that are unique in their nature. Our focus in on the physical characterization of fats and oils, in particular polymorphism, melting behavior, microstructrure and solid fat content. We have strong expertise in rheology as well. These unique capabilities are managed by permanent full-time staff, ensuring a quick turnaround. From a few analyses to major analytical projects, we offer the correct service for you. Our analytical services include the input/advice of Dr. Alejandro Marangoni and his expert team when necessary. A list of the analytical equipment available in our laboratory can be found below.
