glycosylated derivatives (glycosyl-DFAs), a family of prebiotic oligosaccharides. Under optimized conditions, up to 70% of the active DFA species were obtained from a highly concentrated solution of fructose, avoiding the filtration step and contamination risk associated with the current procedures that employ heterogeneous catalysis with acid ion-exchange resins. The optimized CO2-promoted preparation of DFA-enriched
由二氧化碳生成的d-果糖浓缩溶液被二氧化碳活化,可诱导形成二果糖二酐(DFA)及其糖基化衍生物(糖基-DFA),这是一种益生元寡糖家族。在优化的条件下,从果糖的高浓度溶液中最多可获得70%的活性DFA物质,从而避免了过滤步骤和与采用酸离子交换树脂进行多相催化的现有程序相关的污染风险。本文所述的优化的由CO 2促进的富含DFA的焦糖制剂的规模已成功扩大到150 kg d。-果糖用于营养研究,表明该过程的大规模实施是可能的。
