SEATRACES PUBLICATION Bárbara Teixeira, Helena Vieira, Sandra Martins and Rogério Mendes Bárbara Teixeira, Helena Vieira, Sandra Martins and Rogério Mendes, IPMA researchers, recently published a paper in Foods on the Quantitation of Water Addition in Octopus Using Time Domain Reflectometry. This study aimed to develop a rapid and non-destructive method to control abusive water addition…

Comparison of three rapid non-destructive techniques coupled with a classifier to increase transparency in the seafood value chain: Bioelectrical impedance analysis (BIA), near-infrared spectroscopy (NIR) and time domain reflectometry (TDR)

SEATRACES PUBLICATION Ángela Melado-Herreros, Sonia Nieto-Ortega, Idoia Olabarrieta, Graciela Ramilo-Fernández, Carmen G. Sotelo, Bárbara Teixeira, Amaya Velasco, Rogério Mendes Abstract: Bioelectrical impedance analysis (BIA), near-infrared (NIR) spectroscopy and time domain reflectometry (TDR) were compared as non-destructive techniques, coupled with a classifier based on partial least square discriminant analysis (PLS-DA), to assess added water detection in…

Population structure and geographic origin assignment of Mytilus galloprovincialis mussels using SNPs

SEATRACES PUBLICATION Ane del Rio-Lavín, Natalia Díaz-Arce, María Angélica Larraín, Cristian Araneda, Naiara Rodríguez-Ezpeleta, Elisa Jiménez, Miguel Ángel Pardo Abstract: Seafood traceability represents a major goal for regulators and fishing industries worldwide who seek to prevent commercial fraud, protect marine resources and ensure consumer safety. Genetic approaches can be used to trace the provenance of…

Rapid Differentiation of Unfrozen and Frozen-Thawed Tuna with Non Destructive Methods and Classification Models: Bioelectrical Impedance Analysis (BIA), Near-Infrared Spectroscopy (NIR) and Time Domain Reflectometry (TDR)

SEATRACES PUBLICATION Sonia Nieto-Ortega , Ángela Melado-Herreros, Giuseppe Foti, Idoia Olabarrieta, Graciela Ramilo-Fernández, Carmen Gonzalez Sotelo, Bárbara Teixeira, Amaya Velasco and Rogério Mendes Abstract: The performances of three non-destructive sensors, based on different principles, bioelectrical impedance analysis (BIA), near-infrared spectroscopy (NIR) and time domain reflectometry (TDR), were studied to discriminate between unfrozen and frozen-thawed fish.…

Fraud in highly appreciated fish detected from DNA in Europe may undermine the Development Goal of sustainable fishing in Africa

Carmen Blanco‑Fernandez, Alba Ardura, Paula Masiá, Noemi Rodriguez, Laura Voces, Marcelino Fernandez‑Raigoso, Agustín Roca, Gonzalo Machado‑Schiaffino, Eduardo Dopico and Eva Garcia‑Vazquez Abstract: Despite high effort for food traceability to ensure safe and sustainable consumption, mislabeling persists on seafood markets. Determining what drives deliberate fraud is necessary to improve food authenticity and sustainability. In this study,…

Analysis of added phosphates in hake fillets by ion-exchange chromatography: A case study of false positives induced by nucleotides coelution

SEATRACES PUBLICATION Bárbara Teixeira and Rogério Mendes Abstract: This study aimed to optimize an ion-exchange chromatography method for an accurate quantification of phosphates. Coelution of nucleotides was detected following the quantification of small amounts of di- and trimetaphosphates in hake fillets. In some samples, triphosphates were added to the glaze ice, therefore, defrosting waters (glaze…
