Abstract<\/strong><\/p>\n\n\n\n

This study was carried out at the laboratories\nof the Faculty of Technical Engineering, University of Tartus, during 6\/2017,\nto determine the changes in fatty acid content in\nflesh of (Liza aurata<\/em>, Risso, 1810), which is one of the Syrian\ncommercial marine fish species, and that during frozen storage at (-18 \u00b0C) at\nconsecutive time intervals (0, 60,  120, and180) day. Fish samples were randomly\ncollected from sites landing along the beach of Tartus governorate, and approximately (40) individuals were taken for the analysis with three\nreplicates, and an individual for each replication,\nthen kept it at (0-4) \u00b0C directly waiting to be transferred to the laboratory within less than an hour. There\nthe gonads, internal organs, head, bones, skin and blood vessels were removed, then\nfrozen and stored at (-18\u00b0C). The edible muscles of fresh and\nfrozen samples were analyzed only during the studied periods of freezing.\nAccording to the results of the study, L. aurata<\/em> was classified as a\nmedium-fat content fish. The content of Mono Un Saturated Fatty Acids was\nhigher than the Saturated Fatty Acids, followed by Poly Un Saturated Fatty\nAcids (MUFA \u02c3 SFA \u02c3PUFA) for fresh samples, but frozen samples content was (SFA\n\u02c3 MUFA \u02c3PUFA) at the end of the freezing period. The fresh samples content of  L. aurata<\/em> of omega 3 and omega 6) were\n(15 and 4%) respectively, while it attained in the frozen samples (11 and 3.7%)\nduring (0, 180) days of freezing time respectively, due to lipid oxidation, so it is possible to freeze L. aurata<\/em> at (-18\u00b0C) for (5) months while its nutritional value retaining within the limits which\nare suitable for human consumption. Fatty acids have significant differences during\nstorage duration at a significant level of (0.05).<\/p>\n\n\n\n

Key words<\/strong>: Liza aurata<\/em>, Tartus, Omega3, Omega6.<\/p>\n\n\n\n
