摘要
[目的]研究从鹰嘴豆中提取水不溶性膳食纤维的工艺方法，为今后工业化生产提供有效的基础数据。[方法]采用酶碱法提取鹰嘴豆水不溶性膳食纤维，主要考察的4个因素为：α－淀粉酶浓度、中性蛋白酶浓度、NaOH浓度以及浸泡时间，并通过正交试验对4个因素的水平进行了优化处理。[结果]通过正交试验提取鹰嘴豆水不溶性膳食纤维并计算产率，得出酶法提取鹰嘴豆水不溶性膳食纤维的最佳提取工艺参数为：α－淀粉酶浓度1．0％，中性蛋白酶浓度0．5％，NaOH浓度为3．0％，浸泡时间80 min，此时提取的鹰嘴豆水不溶性膳食纤维产率最高，为29．86％。[结论]用复合酶法提取鹰嘴豆膳食纤维大大提高了膳食纤维的提取率。
Abstract
Objective] The aim was to study the technique for extracting water insoluble dietary fiber from chickpea, to provide effective basic data for industrialized production in the future .[ Method] Water insoluble dietary fiber was extracted from chickpea by enzyme alkali , including 4 factors:α-amylase concentration, neutral protease concentration, NaOH contration and soaking time, through orthogonal test, levels of 4 fac-tors were optimized.[ Result] Through orthogonal test, water insoluble dietary fiber was extracted from chickpea and yield was calculated , the optimal extraction parameters were:1.0%α-amylase , 0.5%neutral protease, 3.0%NaOH, soaking time 80 min, the yield of water insoluble dietary fiber from chickpea was up to 29.86%.[Conclusion] Using composite enzymatic method can greatly increase the extraction yield of diet-ary fiber from chickpea.
