Abstract


The fatty acid composition of the liver oil from the Black Sea dogfish Squalus acanthias, as well as its seasonal variations were determined. A scheme for concentration of polyunsaturated fatty acids from the dogfish liver oil by urea complexation was proposed. From 360g of free fatty acids a 48g concentrate was obtained, containing 7,8% C20:4, 16,4% C20:5. 9,2% C22:5 and 49,7% C22:6.

Keywords


Black sea; Liver oil of dogfish; Polyunsaturated fatty acid (concentrate).
