Abstract
The topic of food analysis and safety has attracted increasing interest in recent decades owing to recent scandals concerning fraudulent activities (mislabeling, sophistication, adulteration, etc.) that can undermine human health. Among them, seafood fraud has probably the strongest relationship with food safety, an activity that goes beyond economic interests. This article explores the capabilities of an innovative instrumental setup, called the "iKnife," as a powerful tool in this specific research area, where until now genomics and proteomics have been the workhorses in analytical approaches. iKnife, which means "intelligent knife," is the name of a recent technology based on rapid evaporative ionization mass spectrometry (REIMS). REIMS is an emerging technique able to characterize different samples rapidly, affording a comprehensive profile usable as a fingerprint, without the need for preliminary extraction or cleanup procedures. In detail, a REIMS source is coupled to a high-resolution tandem mass spectrometer; such coupling allows one to maximize the amount of information (discriminant features) collected for a single analysis, as well as to focus on target analytes to achieve enhanced sensitivity and selectivity. A database was created from 18 marine species typical of the Mediterranean Sea, all caught in the very small area of the Strait of Messina, and reliable identification was achieved for each species with confidence higher than 99%. One big model and three submodels were built by principal component analysis and linear discriminant analysis for unambiguous key variable identification within each class (e.g., Cephalopoda), order (e.g., Perciformes), or family (e.g., Carangidae).

Abstract
Few studies applying NGS have been conducted in the food inspection field, particularly on multispecies seafood products. A preliminary study screening the performance and the potential application in NGS analysis of 14 "universal primers" amplifying 16SrRNA, cytb, and COI genes in fish and cephalopods was performed. Species used in surimi preparation were chosen as target. An in silico analysis was conducted to test primers' coverage capacity by assessing mismatches (number and position) with the target sequences. The 9 pairs showing the best coverage capacity were tested in PCR on DNA samples of 53 collected species to assess their amplification performance (amplification rate and amplicon concentration). The results confirm that primers designed for the 16SrRNA gene amplification are the most suitable for NGS analysis also for identification of multispecies seafood products. In particular, the primer pair of Chapela et al. (2002) is the best candidate.

Abstract
The meat of Ruvettus pretiosus and Lepidocybium flavobrunneum (gemfishes) contains high amounts of indigestible wax esters that provoke gastrointestinal disorders. Although some countries have banned the sale of these species, mislabeling cases have been reported in sushi catering. This work developed a simple conventional multiplex PCR, which discriminates the two toxic gemfishes from other potentially replaced species, such as tunas, cod, and sablefish. A common degenerate forward primer and three species-specific reverse primers were designed to amplify cytochrome oxidase subunit I (COI) gene regions of different lengths (479, 403, and 291 bp) of gemfishes, tunas, and sablefish, respectively. A primer pair was designed to amplify a fragment (193 bp) of the cytb gene of cod species. Furthermore, a primer pair targeting the 16S rRNA gene was intended as common positive control (115 bp). The method developed in this study, by producing the expected amplicon for all of the DNA samples tested (reference and commercial), provides a rapid and reliable response in identifying the two toxic species to combat health frauds.

Abstract
BACKGROUND Detection of improper labelling of raw and processed seafood is of global importance for reducing commercial fraud and enhancing food safety. Crabs are crustaceans with intricate morphological as well as genetic divergence among species and are popular as seafood in restaurants. Owing to the high number of crab species available, it can be difficult to identify those included in particular food dishes, thus increasing the chance of supersession. DNA barcoding is an advanced technology for detecting improper food labelling and has been used successfully to authenticate seafood. RESULTS This study identified 11 edible crab species from India by classical taxonomy and developed molecular barcodes with the cytochrome c oxidase I (COI) gene. These barcodes were used as reference barcodes for detecting any improper labelling of 50 restaurant crab samples. Neighbour-joining tree analysis with COI barcodes showed distinct clusters of restaurant samples with respective reference species. The study demonstrated 100% improper labelling of restaurant samples to cover up acts of inferior crab supersession. CONCLUSION DNA barcoding successfully identified 11 edible crabs in accordance with classical taxonomy and discerned improper crab food labelling in restaurants of India.

Abstract
Salted jellyfish, a traditional food in Asian Countries, is nowadays spreading on the Western markets. In this work, we developed a Pentaplex PCR for the identification of five edible species (Nemopilema nomurai, Rhopilema esculentum, Rhizostoma pulmo, Pelagia noctiluca, and Cotylorhiza tuberculata), which cannot be identified by a mere visual inspection in jellyfish products sold as food. A common degenerated forward primer and five specie-specific reverse primers were designed to amplify COI gene regions of different lengths. Another primer pair targeted the 28SrRNA gene and was intended as common positive reaction control. Considering the high level of degradation in the DNA extracted from acidified and salted products, the maximum length of the amplicons was set at 200 bp. The PCR was developed using 66 reference DNA samples. It gave successful amplifications in 85.4% of 48 ready to eat products (REs) and in 60% of 30 classical salted products (CPs) collected on the market.
