Abstract
Bu çalışmada Mersin yöresinden alınan levrek balığı, Dicentrarchus labrax L.'ın total yağ asidi bileşiminin mevsimsel değişimi gaz kromatografi ile araştırılmıştır. D. labrax'ın bileşiminde 12 farklı yağ asidi belirlenmiştir. Yağ asitleri bileşimlerinin C:14 ile C:22 arasında olduğu görülmüştür. Dört mevsimde de doymamış ve aşırı doymamış yağ asitleri toplam yüzdeleri doymuş yağ asitleri yüzdelerinden daha yüksek oranda bulunmuştur. lkbahar ve sonbahar mevsimlerinde en yüksek yüzdeye sahip yağ asidi olarak C 18:1 oleik aside, kış ve yaz mevsimlerinde ise C 16:0 palmitik aside rastlanmıştır. Sonbahar ve kış mevsiminde omega-3 yağ asitleri yüzdeleri, ilkbahar ve yaz mevsiminde ise omega-6 yağ asitleri yüzdeleri yüksek olarak belirlenmiştir.
In this study, total fatty acid composition and its seasonal variotion of sea bass, Dicentrarchus labrax L. which taken from Mersin were investigated by gas chromatographic method. 12 different fatty acids were determined in the compositions of D. labrax. Fatty acids compositions were seen between C:14 and C:22. Total percentages of unsaturated and polyunsaturated fatty acids were higher than saturated fatty acids in four seasons.Oleic acid was determined as fatty acid which has the highest percentage for spring and autumn seasons. Palmitic acid was determined as fatty acid which has the highest percentage for winter and summer seasons. Percentages of omega-3 fatty acids were found high in autumn and winter, whereas percentages of omega-6 fatty acids were high in spring and summer.
