Simultaneous authentication of species identity and geographicalorigin of shrimps: Untargeted metabolomics to recurrentbiomarker ions
(Elsevier, 2019) Chatterjee, Niladri S.
Mandatory disclosure of the species identity, production method, and geographical origin are embed-ded in the regulations and traceability systems, governing international seafood trade. A high-resolutionmass spectrometry-based metabolomics approach could simultaneously authenticate the species iden-tity and geographical origin of commercially important shrimps. The highly innovative approach sparedthe need for multiple testing methods which are in routine use currently. A robust chemometric model,developed using the metabolite fingerprint dataset, could accurately predict the species identity of theshrimp samples. Subsequently, species-specific biomarkers were discovered and a tandem mass spec-trometry method for authentication of the species was developed. Two other chemometric models fromthe metabolomics experiment accurately predicted the geographical origin of king prawns and tigerprawns. The study has shown for the first time that food-metabolomics along with chemometrics cansimultaneously check for multiple seafood fraud issues in the global seafood supply-chain.
