(A) An overlay of CP and CPSP/MAS NMR spectra of low temperature isothermally stored normal maize hydrogels with peak assignment. Peaks of significantly increased local mobility are shown in green. (B) Bar chart of estimated levels of local mobility per signal across all carbon nuclear environments with arrows indicating peaks of increased local mobility. Inlays showing spectral excerpts featuring composite peak deconvolution and assignments (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.).
