| Abstract: |
| Aiming to provide a reference for the green and sustainable development of the fish oil industry, the application of supercritical fluid (SCF) technology in extraction, enrichment of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), structural modification and microencapsulation of fish oil were systematically introduced. The evolving landscape of SCF technology in fish oil processing was prospected. The SCF extraction of fish oil is completed at a lower temperature and inert environment, which can effectively prevent lipid oxidation and maximize its natural bioactivities. The fishy smell and short-chain fatty acid in fish oil can be removed by SCF technology, while EPA, DHA, and other ω-3 polyunsaturated fatty acids can be further enriched, so the additional value of the product is greatly increased. SCF can also serve as a solvent medium for enzymatic structural modification of fish oil to significantly improve the content of EPA and DHA in the product. The production of fish oil microcapsules produced by SCF technology can reduce the use of organic solvents and the quality of product is better. In conclusion, the development of continuous process based on fish oil extraction, enrichment and microencapsulation with SCF technology will become one of the future research directions. |
