摘要：

In this study, the effects of gamma-irradiation on the physicochemical and structure properties as well as the biological activities of Schizophyllum commune polysaccharides were investigated. The results demonstrated that the total carbohydrate content, solubility, fat binding ability and foaming capability of polysaccharides were increased with the increasing gamma-irradiation dose, while the average molecular weight of polysaccharides showed the contrary trend and it significantly decreased from 11.96 to 4.16 kDa. Mannose, glucose and xylose were the main monosaccharides of polysaccharides and gamma-irradiation treatment hardly changed monosaccharide composition, but significantly affected the molar ratio of monosaccharides. gamma-Irradiation treatment slightly improved the crystallinity of polysaccharides, and low-dose gamma-irradiation treatment (4 and 8 kGy) could increase the zeta potential thus improved the stability of polysaccharides solution. Moreover, gamma-irradiation treatment influenced the color and the surface topography of polysaccharides but had less impact on the triple helix structure. High dose gamma-irradiation treatment (8-16 kGy) decreased the thermal stability of polysaccharides as well as the scavenging activity of ABTS radicals. These findings provide valuable insights into the physicochemical modification of polysaccharides via the gamma-irradiation.
