In the context of expanding fish production and complex distribution chains, traceability, provenance food safety tools are becoming increasingly important. Here, we compare elemental fingerprints gilthead seabream (Sparus aurata) muscle from wild different aquaculture productions (semi-intensive earth ponds intensive sea cages two locations) to confirm their origin evaluate concentrations elements with regulatory thresholds (Cu, Hg, Pb Zn). Using a chemometric approach based on multi-elemental signatures, sample was determined an overall accuracy 90%. Furthermore, in model built replicate real-case scenario where it would be necessary trace method S. aurata without reliable information about its harvesting location, 27 30 samples were correctly allocated original (sea-cage aquaculture), despite being another location. The regulated ranged as follows: Cu (0.140-1.139 mg/Kg), Hg (0-0.506 (0-2.703 mg/Kg) Zn (6.502-18.807 only presenting consistently above recommended limit for human consumption. present findings contribute establishing fingerprinting tool methods underpin seafood authentication.

Provenance and traceability are crucial aspects of seafood safety, supporting managers regulators, allowing consumers to have clear information about the origin products they consume. In present study, we developed an innovative spectral approach based on total reflection X-ray fluorescence (TXRF) spectroscopy identify provenance a case study for five economically relevant marine species harvested in different areas Atlantic Portuguese coast: three bony fish-Merluccius merluccius, Scomber colias, Sparus aurata; one elasmobranch-Raja clavata; cephalopod-Octopus vulgaris. Applying first-order Savitzky-Golay transformation TXRF spectra reduced potential matrix physical effects light scattering beam while maintaining differences inherent chemical composition samples. Furthermore, variable importance projection partial least-squares discriminant analysis (VIP-PLS-DA), with k - 1 components (where is number geographical origins each species), produced robust high-quality models classification samples according their origin, several clusters well-evidenced dispersion plots all species. Four displayed overall above 80.0%, whereas lowest accuracy S. aurata was 74.2%. Notably, 10% features that significantly contribute class differentiation shared among The results obtained suggest can be used purposes (from cartilaginous fishes cephalopods) presented chemometric has added value coupling classic peak deconvolution elemental quantification, characterization samples, providing highly accurate informative dataset terms food safety.

Food fraud associated with the intentional mislabelling of non-Protected Geographical Indication (PGI) is a concern for consumers. "Maçã de Alcobaça" (Alcobaça apple) one oldest Portuguese PGI products, characteristic main apple-growing regions in country, being utmost importance to develop traceability and authenticity tools depict certification status these products. Pulp multielement signatures were able discriminate moderate accuracy (65.7 %) different Royal Gala clones, grown within same cultivation area. Moreover, Variable Importance Projection Partial Least-Squares Discriminant Analysis (VIP-PLS-DA) allowed discrimination samples from producers 70.0 % accuracy. Apple cultivars also discriminated accurately (82.0 %). Expanding approach non-PGI production areas, several could be distinguished, according their provenance high accuracy, namely Starking (100.0 accuracy), Granny Smith Fuji (86.7 accuracy) Reineta (90.3 accuracy). The fruit's microelement nutritional traits highlighted higher value, an important trait food reduction, informing consumer product authenticity, providing insights on value high-value market

Abstract This study delves into the Molluscan diversity along Gujarat coast, India, focusing on distribution and habitat suitability of four key species: Cerithium caeruleum, Lunella coronata, Peronia verruculata, Trochus radiatus. Utilizing Species Distribution Models (SDMs) integrated with machine learning algorithms, we assessed impact environmental variables patterns these molluscs. Our findings reveal a nuanced understanding preferences, highlighting critical roles salinity, chlorophyll concentration, water temperature. The MaxEnt model, highest Area Under Curve (AUC) value 0.63, demonstrated moderate discrimination capability, suggesting room for enhancement in capturing complex ecological interactions. spatial analysis indicated random arrangement species, no significant autocorrelation observed. research underscores significance advanced modelling techniques predicting distributions, providing insights crucial conservation sustainable management marine biodiversity coast.
