Abstract: A new dietary fiber was prepared by the enzyme-chemical method using the residue of Angelica sinensis as the raw material. The chemical composition,structural characteristics,and physical and chemical properties of this new A. sinensis dietary fiber (ADF) were determined and analyzed. Next,an adsorption thermodynamic equation was established between the new ADF and sodium cholate,and the adsorption rate of metal ions in vitro being determined. Results showed the new ADF with the following characteristics: ADF moisture content was 1.32%,protein was 5.47%,crude fat was 0.57%,total ash was 5.24%,ADF water holding capacity was 3.2 gg-1,swelling property was 1.3 mLg-1,and water binding capacity was 0.105 1 g. The structural feature analysis demonstrated that ADF and the angelica residue were not the same fiber type. Maximum ADF adsorption on sodium cholate was 40 gg-1 with the absorption mode corresponding to the Freundlich model. Also,the ADF adsorption rate for selected inorganic metal ions(in mgg-1) was nickel was 30.18,copper was 17.47,and lead was 21.22. Thus,this study could provide helpful references for dietary fiber in medicinal plants.[Ch,8 fig. 7 tab. 26 ref.]
