Abstract

In this study, the effects of chitosan extracted from Metapenaeus stebbingi shells and commercial chitosan on lipid oxidation of European eel (Anguilla anguilla L.) during refrigerated storage (+4 degrees C) were examined. The control and treated fillet samples were analyzed periodically for pH value, free fatty acid (FFA), thiobarbituric acid (TBA) number, and peroxide value (PV). The results indicated that both chitosans significantly reduced FFA content, TBA number, and PV (P<0.05). It was concluded that 10 g/L of extracted chitosan solution was the optimal concentration for extending the shelf life of eel fillets.
