Fatty Acid Compositions of Flathead Grey Mullet (Mugil cephalus L., 1758) Fillet, Raw and Beeswaxed Caviar Oils
2 Istanbul Technical University, Chemical Engineering Department, 80626 Maslak- Istanbul, Turkey Viewed : 4849 - Downloaded : 6183 The fatty acid compositions of flathead grey mullet fillet, raw and beeswaxed caviar oils were determined. Palmitic acid (C16:0, 20.3%) was the dominant saturated fatty acid in flathead grey mullet fillet oil. The major unsaturated fatty acids of flathead grey mullet fillet oil were detected as palmitoleic acid (C16:1, 13.9%), oleic acid (C18:1, 10.8%), hexadecatetraenoic acid (C16:4, 11.2%), and octadecatetraenoic acid (C18:4, 12.5%). The most abundant unsaturated and saturated fatty acids of raw caviar oil were determined as palmitoleic (C16:1, 23.6%), oleic (C18:1, 18.8%), hexadecadioneic (C16:2, 12.8%), octadecatetraenoic acid (C18:4, 8.0 %), and palmitic acid (C16:0, 5.9%).
Beeswaxed caviar oil contained palmitoleic (C16:1, 14.6%), oleic (C18:1, 18.6 %), hexadecadioneic (C16:2, 7.9%), octadecatetraenoic acid (C18:4, 13.8%), and palmitic acid (C16:0, 6.7%) as major fatty acids. The total unsaturation fatty acids of raw (82.2%) and beeswaxed caviar oils (78.3%) were higher than that of flathead greymullet fillet oil (61.2%).
Furthermore, the amounts of docosadienoic acid (C22:2) and docosahexaenoic acid (C22:6) of raw and beeswaxed caviar oils were nearly 1.5-2.9 times higher than those of the flathead grey mullet fillet.
