摘要
葡甘聚糖经羧甲基化改性后,其溶解性、抗潮性、成膜性能等明显改善,可用作空心胶囊的囊材。通过正交试验,得出了葡甘聚糖羧甲基化改性作囊材的最佳反应条件:6g魔芋精粉,6g氯乙酸,1 2g碘化钾,70℃水浴反应4h,所得产物的取代度为0 571。研究了改性后羧甲基葡甘聚糖的理化性能。
Konjac glucomannan was denatured by carboxyl methyl. The solubility and film-forming properties were all improved apparently. It can be used as capsule materials. By orthogonal experiment,the optimum denaturing conditions were determined. They were 6 g konjac glucomannan,6 g chloroacetic acid,1.2 g potassium iodide,70℃ and 4 h. The physical and chemical properties of denatured konjac glucomannan were researched.
