Analysis of omega-3 fatty acids content in fresh marine fish
Апстракт
Fish lipids are rich dietary sources of n-3 long-chain polyunsaturated fatty acid (LC-PUFAs). Among n-3 fatty acids, the most important are eicosapentaenoic (20:5 n-3, EPA) and docosahexaenoic (22:6 n-3, DHA) acids which have important roles in the prevention and treatment of different diseases. The aim of this study was to analyze the fatty acid content of fresh marine fish available on the Serbian market. In five species of marine fish (salmon, tuna, mackerel, sardines and hake) the content and composition of fatty acids were analyzed. After lipid extraction, fatty acids were derivatized into volatile methyl-esters. Fatty acids were determined using capillary gas chromatography. Analyses of total lipid content in fresh fish samples and their fatty acid composition revealed that mackerel and sardines were the best dietary sources of LC-PUFAs (4.6 and 4.5 g/100 g, respectively). All analyzed fish samples had significantly higher DHA than EPA content. The highest average EPA content per... 100 g of edible fish was observed in samples of sardines (2.0 g). The results showed that the DHA content of sardines, mackerel and salmon were similar - 2.2 g, 2.6 and 2.3 g/100 g, respectively. Hake and tuna had significantly lower LC-PUFAs, EPA and DHA contents. Although significant variations in n-3 fatty acids' content were noted among individual fish samples, it could be concluded that fresh marine fish available on Serbian market can be cheap and valuable source of LC-PUFAs in daily diet.
