AB Fish and fish by-products are the main natural source of omega-3 polyunsaturated fatty acids, especiallyEPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), both of them with a great importance inthe food and pharmaceutical industries. Comparing to conventional fish oil extraction processes suchas cold extraction, wet reduction or enzymatic extraction, supercritical fluid extraction with carbon dioxideunder moderate conditions (25 MPa and 313 K) may be useful for reducing fish oil oxidation, especiallywhen fish oil is rich in omega-3 such as salmon oil, and the amount of certain impurities, suchas some species of arsenic. Furthermore, taking profit of the advantages of supercritical carbon dioxideas extractive solvent, a coupled extraction-fractionation process is proposed as a way to remove free fattyacids and improve fish oil quality, alternatively to physical and chemical refining procedures.
