| Abstract: |
| Fish oil is rich in nutrients such as omega-3 polyunsaturated fatty acids (ω-3 PUFA), vitamin A/D and natural pigments, and has a variety of nutritional efficacy. To promote the green and sustainable development of the fish oil industry of China and ensure the safety and quality of fish oil products, the green preparation process, standard specifications and nutritional efficacy of fish oil were reviewed based on recent progresses at home and abroad. Several green preparation processes, including aqueous enzymatic extraction, supercritical fluid extraction, ultrasound-assisted extraction, microwave-assisted extraction methods were analyzed. Based on the relevant standard specifications of fish oil at home and abroad, the basic components and quality indicators, pollutant limits, and additive limits of fish oil were elaborated. The nutritional efficacy of fish oil in preventing cardiovascular diseases, anti-inflammation and preventing brain diseases were investigated, and the issues present in the application of fish oil were analyzed and prospected. In the future, it is necessary to conduct extensive research on the development of new preparation process for fish oil, as well as to improve the related standard specifications. Furthermore, it is essential to explore the biological activity mechanisms of fish oil in greater depth. |
