Outline
With the global supply and consumption of seafood increasing year by year, fraudulent behaviors such as passing off inferior products as quality ones, adulteration and mislabeling occur from time to time. This not only infringes on consumers’ interests but may also pose food safety risks. The species identification of seafood has gradually become a hot topic of concern and an important step in ensuring the safety of seafood and safeguarding consumers’ interests. DNA barcoding, as a tool for taxonomy, provides an effective technical means for the species identification of seafood and has been widely applied worldwide. This review mainly introduced the current development of DNA barcoding and summarized the research progress on the application in species identification of various seafood such as fish and crustaceans. Especially when combined with the latest technologies such as next-generation sequencing (NGS) and high resolution melting analysis (HRM), DNA barcoding has broad application prospects in the identification of complex samples like deep-processed seafood. This review will provide technical references for the application of DNA barcoding in the supervision of seafood safety.
