Structural characterization of the lignin obtained in a biomass-to-ethanol process is of importance for the lignin utilization which is in turn economically critical for the process. For steam explosion lignins, it has been found that there is a noticeable amount of pseudolignin structures present, appearing as two unique peaks in 2D HSQC NMR. The structures were elucidated as the condensed structures between lignin with furfural and with hydroxymethyl furfural (HMF) via a double bond connection. All isolated steam explosion lignins contain the structures in a quantity of 1 to 4 furan nuclei per 100 lignin C6 units.
