Enzymatic synthesis of lipids containing long-chain omega-3 fatty acids and evaluation of their properties

The two long-chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have well documented health promoting effects. They are mainly found in marine fats and oils. Enrichment iof these fatty acids from different marine oils has been carried out. The principle behind the enrichment is that many lipases convert these fatty acids much slower than other fatty acids. It was thus possible to remove a large portion of the other fatty acids from the triglyceride molecules and keep EPA and DHA in the glyceride fraction. After removal of the free fatty acids a concentrate of EPA and/or DHA was obtained. This forms an interesting ingredient in functional food products.
