Abstract

ABSTRACT: This study investigated the effect of different levels of Moringa oleifera leaf powder (MLP) on physicochemical, microbiological, and sensory characteristics of chicken patties during cold storage. For MLP extracts, methanolic extract exhibited flavonoid and total phenolic contents of 48.0 and 2010.3 mg/kg, respectively. The aqueous extract of MLP showed high (16.7 mm) and mild (8.7 mm) antimicrobial activity (inhibition zones) against Escherichia coli and Staphylococcus aureus, respectively. In chicken patties, the pH, peroxide value (PV), sensory properties, and microbiological characteristics were all affected ( P ≤ 0.05) by the incorporation of MLP into the patty formula. The PV and bacterial counts were decreased ( P ≤ 0.05) with the increase in MLP concentration; however, their values were increased ( P ≤ 0.05) with the progress of storage period. Moderate level (50 g/kg) of MLP was good ( P ≤ 0.05) in retarding lipid peroxidation and inhibiting microbial growth without affecting the sensory quality of stored chicken patties.
