Detection of adulteration of fish caviar by inductively coupled plasma mass spectrometry

The use of inductively coupled plasma mass spectrometry for differentiation of natural and imitated caviar of various fish species: salmon, sturgeon, and particulate species has been proposed. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) have been used as tools for multivariate statistical analysis. The use of PCA and HCA have allowed effective visualisation of differences between caviar samples in terms of authenticity.
