The Presence of Bioactive Compounds in European Eel ( Anguilla anguilla ) Skin: A Comparative Study with Edible Tissue
The presence of bioactive compounds in European eel ( Anguilla anguilla ) skin was studied. Proximate and lipid class compositions and analysis of the fatty acid (FA) profile (individual FAs; FA groups, i.e., saturated, monounsaturated, and polyunsaturated; FA ratios, i.e., polyunsaturated/saturated...

The presence of bioactive compounds in European eel ( Anguilla anguilla ) skin was studied. Proximate and lipid class compositions and analysis of the fatty acid (FA) profile (individual FAs; FA groups, i.e., saturated, monounsaturated, and polyunsaturated; FA ratios, i.e., polyunsaturated/saturated, ω3/ω6) were determined and compared to the composition of the eel muscle. As a result, higher ( p < 0.05) levels of proteins (271.6 g·kg −1 ), lipids (38.0 g·kg −1 ), ash (27.7 g·kg −1 ), and ω6 FAs were observed in the skin tissue. Contrary, the muscle tissue showed higher ( p < 0.05) moisture, ω3 FA, and ω3/ω6 ratio values. Regarding lipid classes, a higher ( p < 0.05) proportion of phospholipids (111.1 g·kg −1 lipids), free sterols (104.7 g·kg −1 lipids), α-tocopherol (274.0 mg·kg −1 lipids), and free FAs (43.6 g·kg −1 lipids) was observed in the skin tissue.
