Abstract: As a nutritious seafood, commercial sea cucumbers are loved by consumers, but its high price has led to frequent occurrence of food frauds. Driven by economic profits, illegal operators may produce counterfeit or adulterated sea cucumber products. This highlights the paramount importance of tracing the species, geographic origin and production process of commercial sea cucumbers. In light of the current status of the adulteration of commercial sea cucumber products, the analytical techniques for the traceability of sea cucumbers including DNA analysis, elemental analysis, stable isotope analysis and omics methodologies (lipidomics, proteomics and glycomics) are reviewed, and an outlook on future trends is given.

Key words: sea cucumber; traceability analysis; species; geographic origin; production process
