SEC analysis suggests the possibility of condensation among lignin fragments during heat treatment. ATR-FTIR spectroscopy, thioacidolysis, and 2D HSQC NMR demonstrated that a structural rearrangement occurs in the heat-treated GL400 samples, in which the content of α-PEG-β-O-4 linkages decreases along with the proportional enrichments of β-5 and β-β linkages, particularly at treatment temperatures above 160 °C.Although it has been more than 40 years since "health for all" was presented as a focus in the Alma Ata declaration [...]
