Fatty Acid Compositions of Flathead Grey Mullet (Mugil cephalus L., 1758) Fillet, Raw and Beeswaxed Caviar Oils

摘要

The fatty acid compositions of flathead grey mullet fillet, raw and beeswaxed caviar oils were determined. Palmitic acid (C_(16:0), 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 (C_(16:1), 13.9%), oleic acid (C_(18:1), 10.8%), hexadecatetraenoic acid (C_(16:4), 11.2%), and octadecatetraenoic acid (C_(18:4), 12.5%). The most abundant unsaturated and saturated fattyacids of raw caviar oil were determined as palmitoleic (C_(16:1), 23.6%), oleic (C_(18:1), 18.8%), hexadecadioneic (C_(16:2), 12.8%), octadecatetraenoic acid (C_(18:4), 8.0 %), and palmitic acid (C_(16:0), 5.9%). Beeswaxed caviar oil contained palmitoleic (C_(16:1), 14.6%), oleic (C_(18:1), 18.6 %), hexadecadioneic (C_(16:2), 7.9%), octadecatetraenoic acid (C_(18:4), 13.8%), and palmitic acid (C_(16:0), 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 (C_(22:2)) and docosahexaenoic acid (C_(22:6)) of raw and beeswaxed caviar oils were nearly 1.5-2.9 times higher than those of theflathead grey mullet fillet.
