Berton, V. Dupray, H. Atmani, G. Coquerel] Dehydration of trehalose dihydrate implemented by slow heating (1 K min−1), has been monitored by Raman microspectroscopy from 25 to 110°C directly on single crystals. Between 90 and 120°C, gas initially trapped in irregular macroscopic defects, reorganizes to form spherical vacuoles. The Raman analysis of these vacuoles highlights that the areas in vicinity of the defects are the first affected by the dehydration mechanisms. Indeed, the progressive amorphization of the crystal starts around these defects.
