Öğe Comparative Study on Fatty Acid Profiles of Anchovy from Black Sea and Mediterranean Sea (Engraulis encrasicholus L., 1758)(Asian Journal Of Chemistry, 2009) Oksuz, Abdullah; Ozyilmaz, Ayse; Turan, CemalFatty acid profile of anchovies (Engraulis encrasicholus) from Black Sea and Mediterranean Sea were determined by using GC-MS.. A total of 25 fatty acids were identified. The level of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) were found as almost 38, 14.3 and 47.7 % in Mediterranean anchovy (MA). respectively. These levels were followed by 35.40 % (SFA), 29.5 % (MUFA) and 31.27 % (PUFA) in Black Sea anchovy (BSA). Geographical location has no effect on total saturated fatty acids of anchovy, whereas MUFA and PUFA changed significantly. BSA contained greater amount of MUFA and low level of PUFA. Conversely, MA had high level of PUFA and low level of MUFA compare to BSA. The ratio of DHA to EPA was calculated as 5.91 in MA and 1.64 in BSA. Palmitic acid, oleic acid and DHA (22:6 n3) were the most prominent fatty acid in both MA and BSA, DHA level may be considered as a key fatty acid to differentiate MA from the BSA.Öğe A Comparative Study on Proximate, Mineral and Fatty Acid Compositons of Deep Seawater Rose Shrimp (Parapenaeus longirostris, Lucas 1846) and golden Shrimp (Plesionika martia, A. Milne-Edwards, 1883)(Medwell Online, 2009) Oksuz, Abdullah; Ozyilmaz, Ayse; Aktas, Mevlut; Gercek, Gozde; Motte, JelenaProximate, Fatty Acids (FA) and element compositions of two shrimp species, deep seawater rose-shrimp (Parapenaeus longirostris) and golden shrimp (Plesionika martia), were determined. Amount of lipid in P. longirostris and P. martia was found as 1.1 and 2.61%. Proportion of lipid in both shrimps was lower than that of marine fish. Surprisingly, FA profile of these 2 shrimp species can be comparable with that of marine fish. The amounts of PUFA's in both shrimp species were found higher than those of SFA and MUFA. Level of DHA in P. longirostris was significantly (p<0.05) higher than that of P. martia. In addition, major macro elements found in both of the shrimp species were Ca, K, Na, P and Mg. Zinc and iron were the major micro elements followed by Cu and Mn. Heavy metals such as, Cd and Cr, were in below the safe limits.Öğe A comparative study on proximate, mineral and fatty acid compositons of deep seawater rose shrimp (Parapenaeus longirostris, Lucas 1846) and red shrimp (Plesionika martia, A.

The lipid and moisture contents in the two species were found to be significantly different from each other (P<0.05). Lipids of striped red mullet include significantly (P<0.05) higher levels of C14:0, C15:0, C16:1, C17:1, C18:1n9, C18:2n6, C20:3n6, DHA (Docosahexaenoic Acid, C22:6n3) and EPA (Eicasapentaenoic Acid, C20:5n3) fatty acids than those of gold band goatfish. Proportions (%) of SFA (Saturated Fatty Acid), MUFA (Monounsaturated Fatty Acid), and PUFA (Polyunsaturated Fatty Acid), DHA/EPA, and n3/n6 were found to be 39.30, 26.81, 32.18, 3.26, and 5.35 for gold band goatfish and 36.72, 41.83, 18.92, 0.89, and 3.31 for striped red mullet, respectively. K and P were found to be predominant among the 11 measured minerals in the two species. Only the K, Ca, and Na content of the two fish species were found to be significantly different (P<0.05).Öğe Proximate Composition, Fatty Acid Profile and Mineral Content of Wild Brown Trout (Salmo trutta sp.) From Munzur River in Tunceli, Turkey(Asian Journal Of Chemistry, 2011) Kayim, Murathan; Oksuz, Abdullah; Ozyilmaz, Ayse; Kocabas, Mehmet; Can, Erkan; Kizak, Volkan; Ates, MehmetIn present study, the proximate composition, fatty acid profile and mineral content of wild brown trout living in Munzur river (Tunceli/Turkey) were investigated. The average level of protein, lipid, moisture and ash content of muscle of the wild brown trout was calculated to be 17.48, 2.3, 77.8 and 1.5 %, respectively. Thirty fatty acids were identified in this study. Identification of the fatty acid was carried out with gas chromatography-mass spectrometry (GC-MS). The total polyunsaturated fatty acids (PUPA) were found the highest fatty acid followed by that of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). Docosahexaenoic acid (DHA, C22:6n3) and eicosapentaenoic acid (EPA, C20:5n3), linolenic acid (LNA, C18:3n3) and linoleic acid (LA, C18:2n6) were found to be predominant fatty acids in PUFAs with the percentages of 11.25, 6.82, 6.30 and 4.88, respectively. The ratio of n3/n6 and DHA /EPA was calculated to be 4.55 and 1.65, respectively. Twelve elements were determined in this study. Determination of elements was performed with ICP-AES. P and K were the predominant element among the minerals analyzed and calculated to be 1305.56-2967.06 and 1908.68-1220.10 mg kg(-1) in muscle-skin of the wild brown trout, respectively.
