  • 摘要: 【目的】改善麦麸膳食纤维(Wheat Bran Dietary Fiber,WBDF)的理化特性、功能特性及结构特征,提高其资源利用率。【方法】采用羧甲基化改性处理WBDF,并对比分析其改性前后的理化特性、功能特性及结构特征。【结果】成功制备出取代度为0.16的羧甲基化麦麸膳食纤维(Carboxymethylated Wheat Bran Dietary Fiber,CWBDF),其可溶性膳食纤维含量由改性前的3.31%提高到20.76%,持水力、持油力和膨胀力分别提升至改性前的1.81倍、1.31倍和1.30倍,葡萄糖吸附能力最高提升至改性前的2.18倍,胆固醇吸附能力显著提高且表现出良好的无pH依赖性,DPPH和ABTS+自由基清除率分别为改性前的1.33倍和1.53倍,总酚含量提高至改性前的1.74倍,纤维素和半纤维素均发生降解,结晶区被破坏,形成疏松多孔结构,比表面积增大。【结论】羧甲基化改性能显著提高WBDF中可溶性膳食纤维含量,是改善WBDF物理结构并增强其加工和功能特性的有效途径。

摘要: 【目的】改善麦麸膳食纤维(Wheat Bran Dietary Fiber,WBDF)的理化特性、功能特性及结构特征,提高其资源利用率。【方法】采用羧甲基化改性处理WBDF,并对比分析其改性前后的理化特性、功能特性及结构特征。【结果】成功制备出取代度为0.16的羧甲基化麦麸膳食纤维(Carboxymethylated Wheat Bran Dietary Fiber,CWBDF),其可溶性膳食纤维含量由改性前的3.31%提高到20.76%,持水力、持油力和膨胀力分别提升至改性前的1.81倍、1.31倍和1.30倍,葡萄糖吸附能力最高提升至改性前的2.18倍,胆固醇吸附能力显著提高且表现出良好的无pH依赖性,DPPH和ABTS+自由基清除率分别为改性前的1.33倍和1.53倍,总酚含量提高至改性前的1.74倍,纤维素和半纤维素均发生降解,结晶区被破坏,形成疏松多孔结构,比表面积增大。【结论】羧甲基化改性能显著提高WBDF中可溶性膳食纤维含量,是改善WBDF物理结构并增强其加工和功能特性的有效途径。
