The Unique Lipidomic Signatures of Can Be Used to Pinpoint Their Geographic Origin.

The aquaculture of macroalgae for human consumption and other high-end applications is experiencing unprecedented development in European countries, with the brown algae being the flag species. However, environmental conditions in open sea culture sites are often unique, which may impact the biochemical composition of cultured macroalgae. The present study compared the elemental compositions (CHNS), fatty acid profiles, and lipidomes of originating from three distinct locations (France, Norway, and the United Kingdom).
