Zusammenfassung:•Five different lignocellulosic biomass feedstocks were hydrothermally treated.•Elevated hydrothermal conditions linked to structural lignocellulosic changes.•A novel method for quantifying the effects of hydrothermal treatment.•Hydrothermal treatment has a higher impact on higher hemicellulose-cellulose structures. Five biomass feedstocks (Coffee residues, Rice waste, Whitewood, Zilkha black, and Lignin) were hydrothermally processed in a semi-continuous flow rig using 9 different processing conditions (75, 150, 250 °C, and 1, 50, 240 bar). Solid residues produced at low temperature (
