摘　　要：针对异麦芽酮糖母液中产品分离难的问题,研究了一种可行的从异麦芽酮糖母液中分离异麦芽酮糖和海藻酮糖的方法。采用大孔吸附树脂、Na^+型阳离子交换树脂和Ca^(2+)型阳离子交换树脂分别对异麦芽酮糖母液进行分离并采用高效液相色谱法对分离效果、异麦芽酮糖和海藻酮糖的含量进行检测分析,以确定最佳分离方法。异麦芽酮糖分离前的含量为53.8%,经Na^+型树脂分离后含量为89.3%,大孔吸附树脂分离后含量67.5%,Ca^(2+)型树脂分离后含量为76.1%。经分离效果比较,确定采用Na^+型阳离子交换树脂为异麦芽酮糖和海藻酮糖分离的最佳方法。In order to resolve the problem of difficult separation and low purity in isomaltulose production technique, a novelty method was carried out to separate isomaltulose and trehalulose. Macro-porous absorption resin, sodium ion exchange resin and calcium ion exchange resin were used to isolate isomaltulose and trehalulose. The high performance liquid chromatography was used to assay the effect of separation and the content of isomaltulose and trehalulose. The purity of isomaltuolse was 53.8% before separation. The content was 89.3% separated by the sodium ion exchange resin, the content was 67.5% separated by macro-porous absorption resin, and the content was 76.1% separated by calcium ion exchange resin. The method of the sodium ion exchange resin was optimal after comparing and analyzing.
