| 摘 要： | 以花生苗为原料，通过正交实验法，确定花生苗中水溶性膳食纤维的最佳提取工艺条件为：pH=6、温度60℃、提取液用量15mL／g、时间20min．此条件下水溶性膳食纤维提取率为4．97％．同时用化学法、酶法、酶法-9化学法结合法分别提取花生苗水不溶性膳食纤维，通过对3种方法得到的水不溶性膳食纤维进行分析比较，酶法-9化学法结合法得到的水不溶性膳食纤维的持水力和膨胀力分别2．624g·g^-1和1．425mL·g^-1.

| Abstract: | In the study, soluble dietary fiber was extracted from peanut seedling with orthogonal tests. The optimum condition was obtained： pH=5.0, temperature 60℃, extraction dosage15mL/g and time 20rain. By this condition the yield was 4.97%. Several extraction methods （Chemical, enzymatic, enzymatic-chemical） of extracting Insoluble dietary fiber were studied and the properties of products have been compared. It showed that the insoluble dietary fiber by enzymatic-chemical was best, Its water holding power and expansion power were 2.624 g.g^-1 and 1.425 ml·g^-1 respectively. |
