膳食纤维之所以日益受到人们的关注,主要是由于科学家不断发现膳食纤维所特有的理化特性和生理功能。如膳食纤维有很高的持水持油力,对阳离子有结合和交换能力,对有机化合物的吸附壁合作用,具有类似填充剂的充盈作用,可改变肠道系统中的微生物群系组成等等。正是由于膳食纤维的这些理化特征使它具有了以下几个方面的独特生理功能和营养保健作用。膳食纤维是一种资源丰富并有多种生理功能的多糖类物质,对预防某些疾病,保障人体健康起着极其重要的
The reason why dietary fiber is getting more and more people’s attention is mainly due to the continuous discovery of physicochemical properties and physiological functions of dietary fiber. Such as dietary fiber has a high water holding capacity, the cation binding and exchange capacity, adsorption of organic compounds wall cooperation, filling with a similar filler, can change the composition of the intestinal system of microbial flora Wait. It is because of these physical and chemical characteristics of dietary fiber so that it has the following aspects of the unique physiological functions and nutritional health role. Dietary fiber is a rich source of polysaccharides with a variety of physiological functions. It is extremely important for the prevention of certain diseases and the protection of human health.
