Interpretive Summary: This study evaluated the addition of olive leaf powder (OLP) to chilled minced horse mackerel, and its potential inhibitory effect on fish oxidation. The addition of OLP increased significantly the antioxidant capacity of minced fish and correlated with the delayed lipid oxidation over storage. The effectiveness of OLP was concentration-dependent in all parameters studied. The results showed OLP as a potential natural antioxidant for fish products.

Technical Abstract: There is a growing interest in the replacement of synthetic food antioxidants by natural extracts. Olive leaf is an abundant by-product of the olive oil industry. The aim of this study was to investigate the antioxidant capacity of olive leaf powder (OLP) in chilled minced muscle. Concentrations of 0 % (control), 1.5%, 3.5% and 4.5% OLP were added to minced horse mackerel and stored at 4ºC over 3 days. OLP showed a high antioxidant capacity and fiber content. The addition of OLP increased significantly the antioxidant capacity of minced fish and correlated with the delayed lipid oxidation over storage. The effectiveness of OLP was concentration-dependent in all parameters studied. The results showed OLP as a potential natural antioxidant for fish products.
