本工作采用响应曲面法优化了一步酸解氧化制备双醛淀粉的工艺,以玉米淀粉为原料、盐酸（HCl）为酸解剂、高碘酸钠（NaIO4）为氧化剂,设置HCl浓度、淀粉乳浓度、反应温度和反应时间为变量。傅里叶变换红外光谱（FT-IR）和X射线光电子能谱（XPS）分析证明本实验成功制得了双醛淀粉。采用旋转黏度计、扫描电子显微镜（SEM）、X射线衍射仪（XRD）和热重分析仪（TGA）对双醛淀粉的糊化性能、颗粒形貌、结晶结构和热性能进行了表征。结果表明,对醛基含量的影响大小依次为反应温度>反应时间>淀粉乳浓度> HCl浓度。最佳制备工艺为:HCl浓度为1. 2mol/L,淀粉乳浓度为7%,反应温度为49℃,反应时间为4 h。在该...

In this paper, the response surface method was used to optimize the preparation process of dialdehyde starch by one-step acidolysis oxidation. Then corn starch as raw material, hydrochloric acid (HCl) as acid solution and sodium periodate (NaIO4) as oxidant. The concentration of HCl, the concentration of starch milk, the reaction temperature and the reaction time were the variables. Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) analysis proved that the dialdehyde starch was successfully prepared. The...
