Objective

To investigate the feasibility of mineral element analysis for tracing the geographical origin of Salmon.

Methods

The content of 20 kinds of mineral elements in 40 Salmon samples from the Faroe Islands, Norway, Scotland and Xinjiang were determined by inductively coupled plasma mass spectrometry. The obtained data were processed with SPSS 27.0 software for variance analysis, principal component analysis and Fisher discriminant analysis.

Results

The 11 kinds of mineral elements (Na, Mg, K, Ca, Fe, Cu, V, Cr, Co, As, Hg)showed significant differences among the different origins (P<0.05), while 6 kinds of elements (Zn, Sr, Sn, Sb, Pb,Mn) did not show significant differences (P>0.05). According to principal component analysis, the cumulative variance contribution rate of the 4 principal components was 80.864%, and it was determined that 11 kinds of mineral elements, namely Na, Mg, K, Ca, Fe, Cu, V, Cr, Co, As and Hg, were the characteristic factors of the differences in mineral elements among the Salmon from the 4 production areas. The discriminant model established based on these 11 kinds of mineral elements had an overall correct discrimination rate of 100.0% for the origin of fresh Salmon, and the correct rate of cross-validation results was also 95.0%.

Conclusion

Mineral element analysis is an effective method for tracing the geographical origin of fresh Salmon from the Faroe Islands, Norway, Scotland and Xinjiang,providing technical support for combating the misrepresentation of the geographical origin and label fraud of Salmon.
