    • Disclosed are derivatized malto-oligosaccharides and methods for the preparation thereof. In accordance with the disclosed invention, a malto-oligosaccharide is hydrogenated to thereby obtain a hydrogenated malto-oligosaccharide, and the resulting hydrogenated malto-oligosaccharide is derivatized, such as via oxidation, esterification, etherification, or enzymatic modification. The derivatization of such hydrogenated malto-oligosaccharides results in a surprisingly low level of a formation of by-products and products of degradation. In a particularly preferred embodiment of the invention, a mixture of malto-oligosaccharides is catalytically hydrogenated under reaction conditions suitable to substantially preserve the degree of polymerization (DP) profile of the mixture. The resulting malto-oligosaccharide mixture then is derivatized to form a derivatized malto-oligosaccharide mixture.
    • 公开了衍生的麦芽寡糖及其制备方法。 根据所公开的发明,将麦芽糖寡糖氢化以由此获得氢化麦芽寡糖,并且将得到的氢化麦芽寡糖衍生化,例如通过氧化,酯化,醚化或酶改性。 这种氢化麦芽寡糖的衍生化导致副产物和降解产物的形成水平惊人地低。 在本发明特别优选的实施方案中,麦芽低聚糖的混合物在适合于基本上保持混合物的聚合度(DP)分布的反应条件下催化氢化。 然后将得到的麦芽寡糖混合物衍生化以形成衍生的麦芽寡糖混合物。
