Comparison of Fatty Acid Profile of Edible Tissues of Wild Terrestrial Snail (Helix lucorum L. 1758) Collected in Two Province (Adana and Sinop)

The aim of the present study is to compare the crude protein, fat content and fatty acids concentration of snail meat (Helix lucorum Linnaeus, 1758) obtained from Adana and Sinop Province (including 30 snail meat for both region) in Turkey. They were not statistically significant differences in fatty acid profile between two groups. But, in contrast to previous reports, may be due to geographical variation, the results show that the examined snails demonstrated a high content of fat that is between 3.74% and 4.20%. The analyses also indicated that snail meat from Adana province was richer in protein and fat content than Sinop province. In fatty acid composition for both region, monounsaturated fatty acid fraction (MUFA) was dominant followed by saturated fatty acid (SFA) and polyunsaturated fatty acid (PUFA). The ratio of n-3/n-6 and the content of PUFAs were found to be better in Adana province than Sinop. However, for both region, the ratio of PUFA/SFA was lower in H. lucorum than those recommended for nutritional.

Türkiye’de İki İlden (Adana ve Sinop) Toplanan Doğal Karasal Salyangoz (Helix lucorumL. 1758)’un Yenilebilir Dokularındaki Yağ Asidi Profilinin Karşılaştırılması

Bu çalışmanın amacı, Türkiye'de Adana ve Sinop İli'nden (her iki bölge için 30 salyangoz eti) elde edilen salyangoz etinin (Helix lucorumLinnaeus, 1758) ham protein, yağ içeriği ve yağ asitleri konsantrasyonunu karşılaştırmaktır. Yağ asidi profilinde iki grup arasında istatistiksel olarak farklılıklar bulunmamıştır. Ancak, daha önceki çalışmaların aksine incelenen salyangozların %3,74 ile %4,20 arasında yüksek bir yağ içerine sahip olduğu; bu farklılığın coğrafi farklılıklardan kaynaklanıyor olabileceği sonucuna varılmıştır. Analiz sonuçları, Adana ilinden elde edilen salyangoz etinin protein ve yağ içeriğinin, Sinop ilinden elde edilendendaha zengin olduğunu ortaya koymuştur. Her iki bölgeye ait salyangoz etinin yağ asidi bileşiminde, en fazla tekli doymamış yağ asidi oranı (MUFA) tespit edilmiş bunu doymuş yağ asidi (SFA) ve çoklu doymamış yağ asidi (PUFA) izlemiştir. Adana iline ait salyangozlarda n-3/n-6 ve PUFA içeriğinin oranın, Sinop iline göre daha iyi olduğu tespit edilmiştir. Bununla birlikte, H. lucorum'da her iki bölge için PUFA/SFA oranı, beslenme için önerilen oranlardan daha düşük bulunmuştur.
