The Influence of the Extract Obtained from Giant Red Shrimp (Aristaeomorpha foliacea) Shells on Chemical Properties of Cold-Stored Anchovy (Engraulis encrasicolus)

Abstract

This study aims to determine the effects of extract obtained from giant red shrimp (Aristaeomorpha foliacea) shells on the changes in chemical parameters of anchovy (Engraulis encrasicolus) during 18 days of refrigerated storage. Butylated hydroxytoluene (BHT) was used for the comparison of antioxidant effects. The investigation of changes in fish during refrigerated storage indicated that lipid oxidation significantly increased (P<0.05). Compared to control group, BHT and different rates of shell extract were determined to have significant effects on prevention of oxidation. Comparison of total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBA), peroxide, free fatty acids and pH values indicated that the most positive result was found in the BHT added group, which was followed by the groups containing 0.5% and 0.1% of shell extracts, and control group. In this study, it was concluded appropriate to use natural shell extracts besides synthetic antioxidants during the storage of fish.
