Fractionation and structural characterization of LiCl-DMSO soluble hemicelluloses from tomato

► Acetylated hemicelluloses were purified from LiCl-DMSO extracts of tomato cell wall. ► The hemicelluloses structure was analyzed by enzymatic degradation and MALDI-TOF MS. ► A novel substitution of tomato glucomannan side chains by pentose is revealed.
