Polymorphic Structures and Transitions of Triglycerides and Complex Fats: A Guide to X-Ray Scattering Approaches.

ABSTRACT: This contribution provides a comprehensive review of nanostructural aspects in pure triglyceride compared with more complex, real fat systems. Alongside this journey on understanding the crystallization of triglycerides, we provide a practical guide on using X-ray scattering to its fullest extent. Data from public-domain literature of monoacid and mixed-acid saturated and mono-unsaturated triglycerides are reviewed in great depth. On the nanoscale, lamellar stacking and hydrocarbon tilt angles are discussed, and on the molecular scale, trends in the chain packing density and concomitant geometry changes are explained. Useful tools to evaluate lab-scale and synchrotron X-ray scattering data are presented, including (i) electron density profile calculations, decomposing the lamellar repeat d
