摘　　要：以玉米芯为原料,采用纤维素酶解法制备玉米芯可溶性膳食纤维。通过对料液比、酶解时间、酶解温度和酶用量4个因素进行单因素及正交试验,获得了玉米芯制备水溶性膳食纤维的最佳工艺条件。试验结果表明经过α-淀粉酶、糖化酶和碱性蛋白酶预处理生产玉米芯膳食纤维的优化条件为:料液比1︰20(g/mL)、酶解时间110 min、酶解温度45℃、酶解用量5 mL,此时水溶性膳食纤维产率为6.66%。It studied the enzyme based exlraction of soluble dietary fiber from com cob. The effects of four factors, such as the ratio of raw material to extraction solvent, temperature and the time on the yield of soluble dietary fiber and the enzyme dosage were investigated. The results showed that the optimum preparation process conditions for SDF were the liquid ratio of 1 ： 20 （g/ mL）, the time of 110 min, the enzyme dosage of 5 mL and the temperature of 45 °C. Under this condition, the SDF yield was 6.66%.
