The study explores the use of glycolic acid-based deep eutectic solvents (DESs) to extract xylo-oligomers from corncob, achieving a yield of 65.9% under optimal conditions.
The research shows that adding metal inorganic salts can enhance the extraction process, with AlCl promoting rapid xylan hydrolysis and FeCl leading to greater xylo-oligomer accumulation.
Overall, the findings indicate that this method is effective for producing valuable biomass-derived products under mild conditions, potentially benefiting future bioconversion technologies.
