The total acid hydrolysis shows that the polysaccharide consists of galactose, glucose, mannose and rhamnose. The employed physico-chemical techniques of the polysaccharide sequences approach (FT-IR, MALDI-TOF-MS spectrometry, 1H and 13C NMR) indicate that it is a Galactoglucomannan, the main chain consists of major amounts of ?-(1?4)-linked glucose and mannose residues with monosaccharide branches of ?-(1?6) galactose and O-acetyl substituents. The properties of this new glucomannan suggest that it could find an application as a prebiotic in the food industry.eninfo:eu-repo/semantics/embargoedAccessAntioxidant ActivitiesCrataegus AzarolusGalactoglucomannanPrebioticArticle127010.1016/j.molstruc.2022.133889Q30008484218000102-s2.0-85136479335Q2
