Lipids from algae acids

We studied the extraction of lipids from algae (Isochrysis galbana Parke) to verify the possibility to enrich EPA, DHA or other omega-3 fatty acids for healthy products or pharmaceutical application (35). We found that the SFs allow the extraction of lipids from microalgae with interesting fatty acid composition and good extraction yield in comparison with traditional solvents.

The principle problem of algae as sources of lipids is their high water (70-90%) and low lipid content. Despite their lipid content (-7%), the fatty acids of marine algae have aroused considerable interest among researchers for their nutritional value to other marine organisms, occurrence of bioactive conjugated fatty acids, and potential medical applications. The annual production of carotenoids from seaweeds is estimated to be approximately 100 million tons, of which fucoxanthin, the main carotenoids from brown seaweed, contributes more than 10% (Matsuno, 2001).
