Abstract

In this study, Fatty acid composition of the carpet shell Ruditapes decussatus originating from İzmir Bay (Turkey) and effect of depuration on fatty acids were investigated. Identification of fatty acid composition was used gas chromatography/mass spectrometry (GC-MS). The results show that of all fatty acids identified in carpet shell, the polyunsaturated fatty acids (PUFA) is the group with highest percentage. Within this group, the C20:5n-3 (EPA) and C22:6n-3 (DHA) fatty acids show the highest levels. The highest amounts of SFA and MUFA during the depuration were determined in Palmitoleic acid (C16:0) as 12.08-12.95% and Oleic acid (C18:1n9c) as 2.77-3.31, respectively. ∑SFA, ∑MUFA, ∑PUFA at the end of depuration were found to be 25.62%, 6.87% and 37.98% respectively, and the changes in the amount of PUFA, ∑MUFA, ∑PUFA were not found statistically significant
