The polymorphic behavior of lard was systematically investigated by differential scanning calorimetry (DSC) while simultaneously monitoring the formation of the different crystal forms with X-ray diffraction (XRDT). To interpret the complex polymorphic evolution of the sample analyzed by regular DSC, both XRD patterns and DSC curves were recorded at the same time from the same sample (20 mg) using a laboratory-made calorimeter (http://www.umr-cnrs8612.u-psud.fr/Francais/pdf/MICROCALIX.pdf) installed at a synchrotron radiation bench capable of both small- and wide-angle X-ray diffraction and time-resolved experiments. Lard exhibits a large melting range (-30 degrees C
