The chemical composition, physicochemical and in vitro biochemical properties of dietary fibers (DFs) from five types of citrus fruit peels (orange, grapefruit, lemon, gonggan and ponkan) were investigated. The contents of total, soluble and insoluble dietary fibers in citrus fruit peels had no significant difference (p>0.05) and the binding capacities of soluble dietary fibers (SDFs) of orange, lemon, gonggan and ponkan for sodium cholate and cholesterol were significantly (p
