3.3.2. Stage II
The crystallization of MP probably triggers the crystallization of
the higher-melting point TAGs of PO (second crystallization peak in
Fig. 5 and melting peak with peak maximum at 38 °C in Fig. 6D). Consistent
with the XRD results, these TAGs most likely crystallized into
the β′1 polymorph. This assumption is consistent with the change in
microstructure that was observed during cooling (Fig. 8). A change
to a more gritty microstructure could be seen, which is, similar to
the results observed in the case of pure MP, probably attributable to
the presence of an orthorhombic chain packing
