In our previous studies that have demonstrating ¹H LF-NMR energy relaxation time chemical and morphological spectral mapping as an efficient tool to characterize LSO’s thermal oxidation (Resende et al., 2019a,b). In the present study for comparison to their emulsions, both LSO and FO were thermal oxidized with air at 55^oC for 96 hours and their 2D TD fingerprint map are shown respectively at Fig. 2.
