Fatty Acid Composition in Phosphatidylcholine, Phosphatidylethanolamine, Triacylglycerol and Diacylglycerol of the Muscle and Skin Swordfish (Xiphias Gladius)
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
The objective of this study was to quantify the phospholipids in swordfish that are present in both types of muscles, white and red, and in the skin. The content in total lipids was 5.1% in white muscle, 4.5% in the red muscle and 0.5% in the skin. The content in phospholipids was 52mg/100g, 84mg: 100g and 106mg/100g, respectively in the white muscle, the red muscle and the skin. Phosphatidylcholine (PC) dominated in the skin and in the red muscle with respective rates of 61mg and 51mg/100g. The concentrations of phosphatidylethanolamine (PE) were 41 in the white muscle, 41mg in the red muscle and 44.8/100g within the skin. Polyunsaturated fatty acids (PUFA) were dominant in the PC red muscle with a rate of 16%. The most important were linoleic acid (LA) (5.6%) and EPA (3.4%). PUFAs were the most represented in the PE of the white muscle (9.4%) and the skin (8.8%). In the white muscle, PUFA were represented by linoleic acid (1.9%), while in the skin, they were represented by the EPA (4.7%).
