Title (EN) PRODUCTION METHOD FOR ACIDIC XYLOOLIGOSACCHARIDE, AND ACIDIC XYLOOLIGOSACCHARIDE
(FR) XYLOOLIGOSACCHARIDE ACIDE, ET PROCÉDÉ DE FABRICATION DE CELUI-CI
(JA) 酸性キシロオリゴ糖の製造方法及び酸性キシロオリゴ糖
Abstract:
(EN) 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.
(FR) L’invention fournit un procédé de fabrication à coût réduit de xylooligosaccharide acide, qui inclut une étape de dépolymérisation au cours de laquelle une matière première d’origine végétale subit une dépolymérisation, et une étape de désacétylation au cours de laquelle le pH d’une solution d’un produit obtenu à l’étape précédente, est ajusté à 11 ou plus par chauffage d’une base. L’invention fournit également un xylooligosaccharide acide de teneur en groupe acétyle comprise entre 0 et 5,0% en masse. Selon l’invention, il est possible d’obtenir avec un rendement élevé un polysulfate de pentosanne au moyen d’un procédé de fabrication prenant pour matière première le xylooligosaccharide acide de teneur en groupe acétyle comprise entre 0 et 5,0% en masse.
(JA) 本発明により、酸性キシロオリゴ糖のコストが低減された製造方法として、植物由来原料を解重合する工程、及び上記工程で得られた生成物の溶液を塩基の添加によりｐＨ１１以上とする脱アセチル化工程を含む、酸性キシロオリゴ糖の製造方法、ならびにアセチル基含量が０～５．０質量％である酸性キシロオリゴ糖が提供される。本発明のアセチル基含量が０～５．０質量％である酸性キシロオリゴ糖を原料とする製造方法によりポリ硫酸ペントサンを高収率で得ることができる。
