摘要
将木薯淀粉进行H2SO4酸解后制备淀粉纳米晶。用X射线衍射、电子显微镜、红外光谱仪(FTIR)和差示扫描量热仪(DSC)表征酸解后淀粉颗粒的结构,并对其热稳定性进行研究。研究结果表明,木薯淀粉经H2SO4酸解后,淀粉颗粒粒径减小至50~100nm之间;结晶度比原淀粉提高了41%。
Starch nanocrystal are prepared by sulfuric acid hydrolysis of cassava starch.The remaining starch granules after acid hydrolysis are characterized by XRD、SEM、TEM、FTIR and DSC.The results showed that starch nanocrystals with size between 50nm to 100nm.The crystallinity of starch nanocrystal increase 41%,compared to natural cassava starch.
