Supercritical fluid extraction of fish oil from fish by-products: A comparison with other extraction methods

► SFE is an advantageous process for obtaining oil from freeze-dried, low fat, fish by-products. ► SFE can prevent lipid oxidation and reduce extraction of certain pollutants. ► Closed circulation SFE may provide extracts with high volatile content. ► On-line fractionation SFE can provide enhanced quality fish oil with low FFA and oxidation products content.
