T , or vs. t (t standing for time). When several compounds are released within the same T (or t) range, the DTG record shows as a multi-peak profile, that can be deconvolved into a sum of gaussian or gaussian-like peaks, each related to a single compound. This treatment allows the assessment of the kinetics of the release for each single volatile. Food dehydration can be easily simulated with a TG experiment. Significant improvements of classical TG can be achieved by matching the mass loss rate with the simultaneous record of the related DSC trace, that allows evaluation of the associated enthalpy (Fig.

Relaxation of nuclear spins is related either to spin-lattice, or spin-spin interactions, with relaxation times T1 and T2, respectively: The larger the relaxation time the higher the mobility of the molecules that host the relaxing nuclear spin. The 1H spin-spin relaxation signal recorded from dough samples with T2 in the millisecond range is mainly related to mobile water molecules that interact with flour components [30]. Protons of water molecules tightly bound to the substrates or protons of polymers have instead T2 in the range of microseconds.
