We have recently developed a transformation method for representation of different relaxation processes data (DMTA, DETA and 1H-NMR) as a function of free energy of activation in freeze-dried wheat starch gel. In our previous paper [12] the method of transformation was applied for freeze-dried wheat starch gel of density of 0.13 g/cm³, while in this paper we present results of a similar analysis of relaxation parameters measured in a wide temperature range in dehydrated wheat starch gel of a twice lower density. In the system studied, we observed a decreasing value of the complex rigidity modulus, due to much lower degree of crosslinking. Similar courses of dispersion profile obtained with 1H-NMR relaxation method and DMTA method, at temperature ranging from 100 to 380 K, point to a correlation between the nuclear and mechanical relaxation processes, confirming the results of our previous work, which are related to the dynamics of hydroxymethylene groups in freeze-dried starch gel.
