为提高黑糯米的综合利用价值,对黑糯米米糠中水不溶膳食纤维的功能特性进行分析,结果表明:每克黑糯米中水不溶膳食纤维（IDF）可吸附4. 03 g水,持油力和膨胀力分别为3. 04 g/g、1. 79 mL/g;其阳离子交换能力为0. 83 mmol/L,是白糯米IDF的1. 66倍; pH对亚硝酸盐吸附量基本没有影响,在pH=2. 0和pH=7. 0的条件下,黑糯米IDF的亚硝酸盐吸附量分别为348. 59、346. 96μg/g;黑糯米IDF在pH=7. 0时胆固醇吸附量为12. 63 mg/g,优于模拟胃酸环境下（pH=2. 0）的吸附效果;黑糯米IDF在中性条件下（pH=7. 0）对重金属Cd2+体外吸附率为89. 52μg/g,远远高于模拟胃酸环境（pH=2. 0）时的2. 40μg/g。

In order to improve the comprehensive value of the black glutinous rice,the functional properties of insoluble dietary fiber in the black glutinous rice were studied.The results showed that insoluble dietary fiber(IDF)per gram absorbed 4.03g water in the black glutinous rice,with oil-holding capacity and swelling value were 3.04 g/g and 1.79 mL/g.The cation exchange capacity was 0.83 mmol/L,which was 1.66 times higher than IDF from white glutinous rice.pH had no effect on the amount of the nitrite absorption.Under the conditions of pH=2.0 and p...
