“…Here we describe a novel use of Itrax micro X-ray fluorescence (μXRF), a scanner capable of determining the elemental abundance of samples at a resolution of 200 μm. The data obtained from the Itrax μXRF were successfully used to distinguish the geographic origin as well as the production methods of Penaeus monodon from various regions in the Asia-Pacific [ 4 ]. Using Itrax μXRF has several advantages over the conventional methods; it requires minimal sample preparation and it is non-destructive allowing the sample to be used for additional analyses.…”

“…The isotopic technique is usually combined with an elemental profiling technique to increase the accuracy of the traceability methods [157,159,[162][163][164][165]. Elemental profiling techniques rely on digestion of samples into ions, then concentration of the ions is followed by spectroscopic analysis, including atomic absorption spectroscopy (AAS), inductively coupled plasma-optical emission spectroscopy (ICP-OES), and ICP-mass spectrometry (ICP-MS) [11].…”

Animal origin food products, including fish and seafood, meat and poultry, milk and dairy foods, and other related products play significant roles in human nutrition. However, fraud in this food sector frequently occurs, leading to negative economic impacts on consumers and potential risks to public health and the environment. Therefore, the development of analytical techniques that can rapidly detect fraud and verify the authenticity of such products is of paramount importance. Traditionally, a wide variety of targeted approaches, such as chemical, chromatographic, molecular, and protein-based techniques, among others, have been frequently used to identify animal species, production methods, provenance, and processing of food products. Although these conventional methods are accurate and reliable, they are destructive, time-consuming, and can only be employed at the laboratory scale. On the contrary, alternative methods based mainly on spectroscopy have emerged in recent years as invaluable tools to overcome most of the limitations associated with traditional measurements. The number of scientific studies reporting on various authenticity issues investigated by vibrational spectroscopy, nuclear magnetic resonance, and fluorescence spectroscopy has increased substantially over the past few years, indicating the tremendous potential of these techniques in the fight against food fraud. It is the aim of the present manuscript to review the state-of-the-art research advances since 2015 regarding the use of analytical methods applied to detect fraud in food products of animal origin, with particular attention paid to spectroscopic measurements coupled with chemometric analysis. The opportunities and challenges surrounding the use of spectroscopic techniques and possible future directions will also be discussed.

“…Promising methods for shrimp authentication mostly rely on stable isotope and multi-element analysis (Ortea and Gallardo 2015, Gopi et al 2019). However, to date tools were developed using relatively low amount of data, little species diversity (up to 5 Penaeid species, Ortea and Gallardo 2015) and restricted geographical areas.…”

“…As a consequence, to my best knowledge no control organism has yet implemented a method to validate the labelling of production method for Penaeid shrimps. Since Penaeid shrimps are essentially produced in tropical latitudes and developing countries (FAO 2018) and traded over wide geographical areas (Gopi et al 2019), a study encompassing all continents is required. In addition, although farmed animals massively belong to two species (Litopenaeus vannamei and Penaeus monodon), shrimps are often sold peeled or headless, making them barely impossible to differentiate from the tens of wild species and leading to frequent mislabelling (Pascoal et al 2008).…”

Declarations of interest: noneAbstract:Shrimps and prawns are especially subject to food fraud, which has consequences not only on the economy but also represents a potential risk for public health. Fatty acids (FA) of Penaeid shrimps have been largely explored in the literature, and although they are unable to discriminate shrimps geographical origin or species, they might provide an interesting tool to distinguish their production method (wild vs. farmed). The present study is based on a literature compilation of Penaeid shrimp FA profiles encompassing all continents and 28 species. It reveals that the ratio of FA 18:2ω6 + FA 18:3ω3 / FA 16:1ω7 can differentiate wild vs. farmed Penaeid shrimps with 100% accuracy within the 207 FA profiles of the dataset considered. Assuming a normal distribution of the dataset, 94.4% of the farmed shrimps population is expected to fall above 2.92, and 99.7% of the wild shrimps population is expected to fall below 2.92.2
