摘　　要：采用热失重法(TG)和差示扫描量热分析技术(DSC)对松谷Fibersol2抗性淀粉进行热性质分析。TG曲线显示该抗性淀粉在293.85℃开始分解,312.37℃分解速度最快,330.89℃是分解的最终温度。DSC吸热曲线显示,样品在24.36℃左右开始出现吸热峰,相变高峰温度约在98.54℃(相变焓179.1J/g),另外在204.23℃和225.48℃出现两个小的吸热峰,表明样品以支链晶体结构为主。Thermogravimetric (TG) and Differential Scanning Calorimeter (DSC) were used to determine the thermal property of resistant starch Fibersol 2 in this paper. The TG curve indicated that this kind of resistant starch began to decompose at 293.85℃. The fastest decomposition rate was achieved at 312.37℃ and the decomposition ended at 330.89℃. The DSC curve showed that besides two small endothermic peaks at about 204.23℃ and 225.48℃, one big endothermic peak appeared at about 24.36℃, and the peak temperature of ...
