摘要：Wrinkle Floweringquince (Chaenomeles speciose (Sweet) Nakai) seed, as an unexploited forestry residue, contains considerable amount of bioactive carbohydrates with potential functionality, which was not widely concerned. The aim of this study is to determine the basic characterizations (molecular weight and functional group), specific components (carbohydrate, protein and uronic acid contents), and functional properties of Chaenomeles speciosa seed gum (CSG). Results indicated that carbohydrate (63.80%), protein (13.69%) and uronic acid (10.30%) contents were achieved. The CSG (average molecular weight, 9.85 × 106 u) consists rhamnose, arabinose, xylose and glucose in a molar percentage of 29.77?10.54?18.55?15.84, respectively. The Fourier transform infrared (FT-IR) analysis revealed hydroxyl, carboxyl and methyl groups and α-glycosidic linkages are founded in the CSG. The CSG was surface active and its ability to decrease surface tension was comparable to commercial gums. Moreover, the CSG solutions showed pseudoplastic flow behavior under dynamic shear rate at high concentrations. The GSC also presented good emulsifying and foaming properties, indicating the potential of the GSC as bioresource stabilizer and thickener in industry. ? 2019 Nanjing Forestry University
