Fish oil is a kind oil extracted from fatty fish oil. It is rich in highly unsaturated n-3 polyunsaturated fatty acids (PUFA), like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which have health benefits for human body, such as anti-inflammatory, regulating blood lipid. Therefore, an increasing number of people are likely to choose foods with these fatty acids, which promotes the production of fish oil and PUFA concentrates.
Methods for Fish Oil Extraction
At present, the extraction methods for fish oil mainly includes pressing method, cooking method, traditional solvent method, supercritical CO2 method and subcritical solvent extraction method. However, which method is environment-friendly? Which method has higher yield? Which method causes minimum degradation for nutrients and active components? Below simply introduce the pros and cons of each method for fish oil extraction.
|Fish Oil Extraction Methods||Pros||Cons|
|Sub-critical Biological Extraction||
In conclusion, the sub-critical biological extraction method is the most suitable process for fish oil extraction. It has many outstanding features compared to traditional extraction methods and super-critical extraction process. (See More Oil Extraction at Solvent Extraction Unit)
