Abstract

Krill oil has recently gained attention as a popular dietary supplement due to its high bioavailability and the presence of potent antioxidants such as astaxanthin. In this study, the fatty acid profiles of different commercial krill oil supplements (KOs) were determined using the Gas Chromatography-Flame Ionization Detector (GC-FID) technique. Based on the results, the total saturated fatty acids (SFA) ranged from 11.70% to 51.59%, monounsaturated fatty acids (MUFA) from 32.13% to 52.50%, and polyunsaturated fatty acids (PUFA) from 9.22% to 55.17%. The predominant fatty acids identified were palmitic acid (C16:0), linoleic acid (C18:2 ω−6), oleic acid (C18:1 ω−9), docosahexaenoic acid (DHA, C22:6) and eicosapentaenoic acid (EPA, C20:5). Additionally, very low levels of trans fatty acids (0.28–3.96%) were observed across all samples. The findings demonstrate that the fatty acid composition of KOs varies significantly depending on the source of raw materials and the specific production parameters employed. This research provides valuable data for the nutritional classification and commercial development potential of krill oil supplements.

Özet

Krill yağı, yüksek biyoyararlanımı ve astaksantin gibi güçlü antioksidanların varlığı nedeniyle son zamanlarda popüler bir besin takviyesi olarak dikkat çekmiştir. Bu çalışmada, farklı ticari krill yağı takviyelerinin (KOs) yağ asidi profilleri Gaz Kromatografisi-Alev İyonizasyon Dedektörü (GC-FID) tekniği kullanılarak belirlenmiştir. Sonuçlara göre, toplam doymuş yağ asitleri (SFA) %11.70 ile %51.59 arasında, tekli doymamış yağ asitleri (MUFA) %32.13 ile %52.50 arasında ve çoklu doymamış yağ asitleri (PUFA) %9.22 ile %55.17 arasında değişim göstermiştir. Belirlenen başlıca yağ asitleri palmitik asit (C16:0), oleik asit (C18:1 ω−9), linoleik asit (C18:2 ω−6), eikosapentaenoik asit (EPA, C20:5) ve dokosaheksaenoik asit (DHA, C22:6) ‘den oluşmaktadır. Ayrıca, tüm örneklerde çok düşük miktarlarda trans yağ asidi (%0.28–3.96) tespit edilmiştir. Elde edilen bulgular, ticari krill yağı ürünlerinin yağ asidi bileşiminin, hammadde kaynağına ve kullanılan spesifik üretim parametrelerine bağlı olarak önemli ölçüde değiştiğini göstermektedir. Bu araştırma, krill yağı takviyelerinin besin sınıflandırması ve ticari geliştirme potansiyeli için önemli veriler sağlamaktadır.
