膳食纤维定义及分析方法研究进展

Review in Defining Dietary Fiber and Analysis Methods

随分析方法学及生理学方面的研究日益深入,膳食纤维在定义上进行了扩充,分析方法也有了一定的发展。为了解不同分析方法及其适用的范围,本文综述了膳食纤维定义的演变、常用分析方法,比较了不同分析方法膳食纤维测定值,并对几种不消化碳水化合物(抗性淀粉、果聚糖、多聚葡萄糖等)的分析方法能否作为AOAC酶重量法的补充进行了说明。

The definition and analytical methods of dietary fiber（DF） have been developed significantly with the increasing intensive research in physiology and analytical methodology. In order to clarify the application of these various methods in routine analysis, this article reviewed the development of DF definition, the methods for routine analysis, and the DF contents comparison obtained by different quantion methods. Meanwhile, it also illustrated whether the methods for non-digestible carbohydrates （such as resistant starch, fructans, and polydextrose） could be used as supplements to the AOAC enzymatic-gravimetric methods.
