为了研究魔芋低聚糖的制备和分离，采用γ射线和β-甘露聚糖酶联合降解魔芋葡甘聚糖，然后通过超滤分离降解产物。值得注意的是，通过这种方法获得的大多数魔芋寡糖的分子量都低于2200 Da。此外，1000 Da分子量截留膜可以有效分离魔芋低聚糖。综上所述，γ射线与β-甘露聚糖酶联合应用是一种获得魔芋低聚糖的有效方法，并且超滤可以有效分离分子量低于1000 Da的低聚糖。 (C) 2012 Elsevier Ltd. 保留所有权利。
To study the preparation and separation of Konjac oligosaccharides, Konjac Glucomannan was degraded by the combination of gamma-irradiation and beta-mannanase, and then the degradation product was separated by ultrafiltration. To our interest, for most of Konjac oligosaccharides obtained by this method, the molecular mass was lower than 2200 Da. In addition, the 1000 Da molecular weight cut off membrane could effectively separate the Konjac oligosaccharides. In conclusion, the combination of gamma-irradiation and beta-mannanase was an efficient method to obtain Konjac oligosaccharides, and the oligosaccharides of molecular mass lower than 1000 Da could be effectively separated by ultrafiltration.
