Conclusions
With these SAXS/WAXS measurements, we have gained insight into
the morphological differences generated by 2 thermal routes towards
solidification from melt of cocoa butter.
• Untempered cocoa butter:
Cooling fast in the fridge then bring back to
room temperature
• Tempered cocoa butter:
Cooling to room temperature, then tempering
at 35 °C, then bring back to room temperature
