| Popis: | In 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 (PUFA) 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. |
