Beschreibung
Zusammenfassung:	The present invention provides a reduced-cost production method for an acidic xylooligosaccharide, the production method including a step for depolymerizing a plant-derived starting material and a deacetylation step for adding a base to a solution of the product of the depolymerization step to make the pH at least 11. The present invention also provides an acidic xylooligosaccharide that has an acetyl group content of 0-5.0 mass%. The acidic xylooligosaccharide that has an acetyl group content of 0-5.0 mass% can be used as a starting material to produce pentosan polysulfate in high yields.
