摘要：
With ponkan residue as raw material, the extraction methods of soluble dietary fiber (SDF) by water extraction, cellulose and high-pressure homogenization coupled cellulose were respectively studied in this paper. The result showed that the absorption capacities of W-SDF, C-SDF and HC-SDF for sodium cholate were 313.1 mg/g, 560.0 mg/g and 761.2 mg/g, respectively; The absorption capacities for cholesterol were 4.80 mg/g, 10.95 mg/g, 9.11 mg/g (pH 2) and 5.43 mg/g, 11.87 mg/g, 10.58 mg/g (pH7), respectively; The removal rate for NO2- were 23.03%, 18.48% and 31.12%, respectively; The inhibitory rate for pancreatic lipase activity were 11.96%, 31.69% and 35.80%, respectively. The apparent viscosities of W-SDF, C-SDF and HC-SDF were 0.104 pa·s, 0.188 pa·s and 0.245 pa·s, respectively. The solution of SDF from ponkan residue was pseudoplastic fluid which viscosity decreased with the increasing of shear rate. ©, 2015, Chinese Institute of Food Science and Technology.
