Identification of structural features of various (O-Acetylated) Xylo-Oligosaccharides from Xylan-Rich agricultural by-products: A review

Research output: Contribution to journal › Article › Academic › peer-review

Abstract

Hydrolysates obtained by hydrothermal treatment of four xylan rich by-products (wheat bran, brewery's spent grain, corn cobs and Eucalyptus wood) were characterised. Depending on the feedstock material studied, a wide variety of differently substituted xylo-oligosaccharides (XOS) and xylan-fragments were obtained. The structural features of the this way obtained arabinose, 4-O-methylglucuronic acid and O-acetyl substituted XOS are reviewed. High performance anion-exchange chromatography (HPAEC),reversed phase (RP)-high performance liquid chromatography (HPLC), mass spectrometry (MS), NMR spectroscopy, RP-HPLC-MS and RP-HPLC-NMR showed to be very useful for the separation and characterisation of the detailed structures of the substituted XOS
