果实膳食纤维组成研究进展 Advances in Research on the Composition of Dietary Fiber in Fruits

膳食纤维指抗人体小肠消化吸收，但在大肠中能部分或全部发酵的可食用植物性成分——碳水化合物及类似物质，包括纤维素、半纤维素、木质素、果胶、抗性淀粉、寡糖等，按溶解性分为可溶性膳食纤维和不溶性膳食纤维两类。本文综述了“高纤维”、“纤维源”果品及高品质膳食纤维，从寡糖、抗性淀粉及细胞壁组分等方面综述了果实膳食纤维组成的研究进展，并进一步挖掘了果实总膳食纤维、可溶性膳食纤维和不溶性膳食纤维的单糖组成。 Dietary fibre means carbohydrate polymers which are not hydrolyzed by the endogenous enzymes in the small intestine of humans, including cellulose, hemicellulose, lignin, pectin, resistant starch and oligosaccharide, which was divided into two types as soluble dietary fiber and insoluble dietary fiber according to the solubility. This article summarizes the “high fiber”, “fiber source” fruit and high quality dietary fiber. The research progress of dietary fiber composition in fruits was reviewed from the aspects of oligosaccharides, resistant starch and cell wall component. The monosaccharide composition of total dietary fiber, soluble dietary fiber and insoluble dietary fiber was also reviewed.
