38 inorganic elements in Shanxin extra aged vinegar and Zhenjiang vinegar were analysed through ICP-AES and ICP-MS.12 characteristic elements,which were Cd,Al,Ca,Ba,Fe,Mn,Zn,Ni,Pb,Cs,As,Mo,were selected by significant test(T test).The principal component analysis(PCA) showed obvious differences between the two vinegars.The contents of 12 characteristic elements were concerned with the local geological condition and processing technique.The inorganic elements determination was expected to be a discrimination method for authenticity of Chinese geographical indication vinegars.
