Omega-3 polyunsaturated fatty acids (ω-3PUFAs) have gained increasing interest in recent years due to their beneficial effects in maintaining heart health and regulating blood pressure, improving brain function, strengthening memory, and reducing depression. Fish and algae are known as the main sources of ω-3PUFAs. In the meantime, extracting fish oil from less-exploited species or fish waste not only creates higher added value, but also reduces environmental pollution caused by the process of disposal of fishery waste. In this study, the most common methods of oil extraction from marine sources, such as solvent-based methods (Soxhlet, Bligh and Dyer, and Folch Methods), supercritical fluid extraction (SFE) and enzymatic hydrolysis, along with their advantages and disadvantages, were investigated. Among them, Soxhlet extraction provides a high yield of lipids; Of course, choosing the right solvent is the most important factor in the effective extraction of lipids. However, continuous heating at the boiling temperature could lead to lipid oxidation and degradation of heat liable compounds. Therefore, development of alternative extraction and purification methods based on the use of green technologies and the sustainability principles, avoiding the use of organic solvents and high temperatures, is needed in order to produce omega-3 polyunsaturated fatty acids of higher purity and quality. Supercritical fluid extraction with environment-friendly solvents and enzymatic hydrolysis are the most promising green technologies for extracting fish oil, whereas pressurized extractions are suitable for extracting microalgae oil.
