酶法提取芦笋皮中高活性膳食纤维的研究

Extraction of high activity dietary fiber from asparagus peel by enzyme

摘要: 以芦笋皮为原料，采用酶法水解制备高活性膳食纤维。试验结果表明：用0.54%的脂肪酶(100 U/mg)、0.80%的淀粉酶(25 U/mg)和0.80%的糖化酶(20 U/mg)、1.20%的蛋白酶(100 U/mg)可提取出高活性的膳食纤维。所得膳食纤维纯度高，总膳食纤维含量达83.08%，其中水溶性膳食纤维17.02%，不溶性膳食纤维66.06%。而且生理活性好，持水性和溶胀性分别为886%和4.5 mL/g。

Abstract: Asparagus peel as raw materials, adopting enzyme hydrolysis method, extract the high active dietary fibre. Result indicated that, the high active dietary fibre could be extracted with 0.54% lipase(100 U/mg), 0.80% amylase (25 U/mg) and saccharase (20 U/mg), 1.20% protease (100 U/mg). Quality of the dietary fibre was high, total content of dietary fibre was 83.08%, among them the soluble dietary febre accounted for 17.02%, the insoluble dietary fibre accounted for 66.06%. And the physiological activation was good, holding water capacity and swelling property were 886% and 4.5 mL/g respectively.
