摘要
使用脱盐菊粉,以强酸型阳离子交换树脂作为固体酸进行菊粉的催化水解,然后经真空浓缩制备出质量良好的高果糖浆。菊粉水解的适宜条件为:选用D061强酸型阳离子交换树脂作为固体酸,固体酸与菊粉溶液(20%)比例为1∶3,在75℃下水解120min,菊粉水解率达92.0%。菊粉溶液的脱盐是成功实现固体酸水解及固体酸多次使用的关键工艺之一。
Inulin hydrolysis catalyzed with strongly acidic cation resins as solid acids was investigated by suing desahed inulin solutions and high fructose syrups with high quality were obtained after being vacuum concentrated. The optimal conditions for inulin hydrolysis were： D061 strongly acidic cation resin as solid acid; the ratio of solid acid and inulin solution （20 %） 1＂3; hydrolysis temperature 75 ~C; hydrolysis time 120 min. Percentage of hydrolysed Inulin with this method was 92.1%. Desalting from inulin solution was one of the key technologies for successful inulin hydrolysis with solid acid.
