Effects of H₂O₂ pretreatment on the elemental fingerprints of bivalve shells and their implications for the traceability of geographic origin.

ABSTRACT: The fraudulent mislabelling of seafood geographic origin has been growing due to complex supply chains and growing consumer demand. To address this issue, seafood traceability tools, such as those based on elemental fingerprints (EF) of bivalve shells, have been successfully used to confirm their harvesting location. However, despite the usefulness of these methodologies, there is still room for optimization. Therefore, this study evaluated the effects of a routine procedure during bivalve shells preparation for ICP-MS analysis - their pretreatment with H₂O₂ to remove organic components. More specifically, the present study evaluated the effects of H₂O₂ on i) the elemental fingerprints of shells of two bivalve species (Ruditapes philippinarum<
