Preparation of polyunsaturated fatty acid concentrates from the liver oil of dogfish (Squalus acanthias) from the Black Sea.
Keywords:Black sea, Liver oil of dogfish, Polyunsaturated fatty acid (concentrate).
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.
