In the present work, we focused our attention on triacylglycerols. Their phase behavior strongly influences production processes of products based on fats and oils. However, the mechanisms controlling such behavior are not well understood. Hence, we decided to utilize computer simulation to gain more understanding in this matter. Using molecular dynamics simulation, we tried to mimic the thermal transition of triacylglycerols from liquid to solid state in order to shed more light on the crystallization of these species.
The main conclusions are that due to the large time scale of the crystallization process, computer resources and time available for this work were not sufficient to simulate the full phase transition of triacylglycerols. Nevertheless, we managed to observe the first structural changes that drive the crystallization, i.e., the strong tendency of oxygen atoms to group and isolate themselves from the hydrocarbon chains. The successfully created molecular models are now ready for further investigations.
