Abstract
In this work the attention is focused on the thermal properties of trehalose, a glass-forming disaccharide which is very effective as a shelf-life extending compound in food industry. A wavelet analysis of Elastic Incoherent Neutron Scattering (EINS) intensity data as a function of the exchanged wavevector on trehalose and its homologous, maltose and sucrose, is presented. This analysis, which allows to highlight the correlation between the signal and the set of the scaled and translated mother functions, reveals the existence of different kinds of protons dynamics which cover different spatial scales. Differently from previous analyses, it emerges that the energy distribution as a function of the exchanged wavevector for trehalose mixture is less sensitive to temperature changes. Furthermore, the application of a new fitting model to the partial and global EINS intensity data as a function of temperature allows to put into evidence both the different wavevector dependence of the system relaxation times, extracted from the intensity vs temperature inflection point, and the higher thermal resistance of trehalose in respect to the other investigated disaccharides.
