摘要: 对膳食纤维的分析方法-郑建仙等人提出的冷水性洗涤剂纤维提取法(CNDF法)作了改良,改良法先行提取分离了原料中的水溶性膳食纤维成分,避免了由于强烈的溶剂作用而造成的损失,因而测定结果更科学、准确,且由于用抽滤代替了原方法中的离心分离,而显得更方便实用。

关键词: 膳食纤维, CNDF法, 测定

Abstract: In the paper, the cold neutral detergent fiber (CNDF) assay suggested by Zheng Jianxian has been improved greatly. In the improved method, the solube dietary fiber was prior extracted and separated, so the restult was more scientific, accurate. And the improved method was more convenient and practical because of substtuting the reduced pressure - filter for the centrifugation.
