The purpose of this study was to evaluate the feasibility of Raman spectroscopy for predicting purity of caviars. The 93 wild caviar samples of three different types, namely; Beluga, Asetra and Sevruga were analysed by Raman spectroscopy in the range 1995cm −1 to 545cm −1 . Also, 60 samples from combinations of every two types were examined. The chemical origin of the samples was identified...
