摘要

为了快速鉴别或检测稻米是否经过辐照杀虫处理，研究了粳米经辐照处理后淀粉粘滞性谱的变化规律。结果表明，随吸收剂量增大淀粉粘滞性显著下降，在检测助剂的调控下，辐照与未辐照的淀粉粘滞性谱有明显差异。利用淀粉的最高粘度、热浆粘度、冷胶粘度与吸收剂量之间的变化关系，可估算稻米辐照后的吸收剂量。借助检测助剂的调控，可快速检测稻米是否经过辐照处理。

Abstract

To rapidly detect whether the rice has been treated with irradiation to eliminate quarantine pests, the changes of starch viscosity profile of glutinous rice after irradiation were studied. The results show that the starch viscosity decreases dramatically with increasing the absorbed dose and under the regulation of detection auxiliary. The absorbed doses could be estimated with the relation between the peak viscosity, the hot paste viscosity, the cool paste viscosity and irradiation dose respectively. With the regulation of detection auxiliary we could rapidly detect whether the rice has been treated with irradiation.
