The PUFA, MUFA and SFA content of the nisin treatment groups were found to be higher than the control group at the end of the storage and it was concluded that this was due to the antioxidant properties of the nisin.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this study the effects of nisin used at different concentrations (0.2%, 0.4% and 0.8% w/v) on the fatty acids profile of sea bass (Dicentrarchus labrax) fillets were investigated under chilled storage.
📊
Key Findings & Data:As a result of the fatty acid analysis, high concentration saturated fatty acids (SFA) were determined as myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) and high concentrations of monounsaturated fatty acids (MUFA) were determined as palmitoleic acid (C16:1), oleic acid (C18:1n9), waxenic acid (C18:1n7), eicosenoic acid (C20:1n9).
💡

Abstract

In this study the effects of nisin used at different concentrations (0.2%, 0.4% and 0.8% w/v) on the fatty acids profile of sea bass (Dicentrarchus labrax) fillets were investigated under chilled storage. As a result of the fatty acid analysis, high concentration saturated fatty acids (SFA) were determined as myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) and high concentrations of monounsaturated fatty acids (MUFA) were determined as palmitoleic acid (C16:1), oleic acid (C18:1n9), waxenic acid (C18:1n7), eicosenoic acid (C20:1n9). Polyunsaturated fatty acids (PUFA) which were determined at high concentration were linoleic acid (C18:2n6), linolenic acid (C18:3n3), eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3). It was determined that sea bass fillets had nutritional values rich in unsaturated fatty acid contents. The PUFA, MUFA and SFA content of the nisin treatment groups were found to be higher than the control group at the end of the storage and it was concluded that this was due to the antioxidant properties of the nisin. Fatty acids composition analysis indicated that presence of the nisin preserved nutritional quality of fish lipid.

Özet

Bu çalışmada, farklı konsantrasyonlarda (% 0.2, % 0.4 ve % 0.8) kullanılan nisinin soğukta depolanan levrek (Dicentrarchus labrax) filetolarının yağ asitleri üzerine etkileri araştırılmıştır. Yapılan yağ asidi analizleri sonucunda yüksek oranlarda tespit edilen doymuş yağ asitleri (SFA) miristik asit (C14:0), palmitik asit (C16:0), stearik asit (C18:0) olarak belirlenmişken, yüksek oranlarda belirlenen tekli doymamış yağ asitleri (MUFA) palmitoleik asit (C16:1), oleik asit (C18:1n9), vaksenik asit (C18:1n7), eikosenoik asit (C20:1n9) olarak belirlenmiştir. Yüksek oranlarda tespit edilen çoklu doymamış yağ asitleri (PUFA) ise linoleik asit (C18:2n6), linolenik asit (C18:3n3), eikosapentaenoik asit (EPA, C20:5n3) ve dokosahekzaenoik asit (DHA, C22:6n3) olmuştur. İncelenen levrek balığının doymamış yağ asidi içerikleri açısından zengin besinsel değerlere sahip olduğu tespit edilmiştir. Nisin muamele gruplarının depolama sonundaki PUFA, MUFA ve SFA içeriği kontrol grubundan daha yüksek olduğu belirlenmiş ve bu durumun nisinin antioksidan özelliğinden kaynaklandığı sonucuna varılmıştır. Yağ asitleri kompozisyon analizi sonuçlarına göre, nisin varlığının balıkta lipit kalitesini koruduğu gözlenmiştir.
