| 摘 要： | 研究了ESR波谱技术检测淀粉类辐照食品的方法。测定不同剂量辐照处理的玉米粉、小麦粉和糯米粉的电子自旋共振（ESR）波谱。结果表明：未辐照和辐照样品的ESR波谱有明显区别，ESR信号强度随着样品辐照吸收剂量的增加而增强。利用ESR试验结果与电镜图像进行比较。利用ESR波谱技术能够鉴别出含淀粉类辐照食品（玉米粉、小麦粉和糯米粉）是否经过辐照。

| Abstract: | The detection method of irradiated starch food by Electron Spin Resonance(ESR)technique is repooted.Maize powder,wheat powder and glutinous rice powder were treated by different dose irradiation,and the results showed that the ESR spectroscopy of starch material was obviously difference before and after irradiation.The intensity of ESR signal increased with the increasing of the irradiation dose.The results obtained by ESR method were also checked by the electron micrographs.It is concluded that ESR techniq... |
