摘　　要：利用元素分析法对3个产地的香米进行鉴别,利用电感耦合等离子体质谱法(ICP-MS)和电感耦合等离子体光谱法(ICP-OES)对来自泰国、江西、湖南3个地区的180份香米进行包括钙、铁、钾、镁、锌、硼、铝、铬、锰、钴、镍、铜、砷、锶、硒、镉、铯、钡、铅19种元素在内的含量分析,通过判别分析建立判别模型。判别模型对泰国香米自校验交叉校验准确率100%,拥有极高的准确率。The research set up a regional discrimination method for 3 kinds of rice by multi-element analysis.180 kinds of rice from 3 places of origin were collected,including Thailand,Jiangxi,Hunan.The concentration of 19 elements（Ca,Fe,K,Mg,Zn,B,Al,Cr,Mn,Co,Ni,Cu,As,Sr,Se,Cd,Cs,Ba,Pb）were determined by ICP-MS or ICP-OES.Discriminatory analysis was applied in building up a regional discrimination model,which reached an accuracy of 100%for both self verification and cross validation.
