Abstract : The physicochemical and nutrient properties of stored palm oil was assessed in this study. Stored and freshly produced palm oil samples were obtained from Ngor-Okpala L.G.A of Imo state, Nigeria The acid, iodine, ester, refractive index, moisture content, sap, peroxide and viscosity values were assessed using standard biochemical methods. Results indicate that acid , iodine, sap, refractive index , esters , viscosity , peroxide and moisture values for both fresh and stored oil were respectively 10.0 and 18.0mg/g; 40.20 and 49.50mg/g; 200 and 210mg/g; 12.2 and 21.2mg/g; 1985 and 1250mg/g; 12.4 and 14.3mg/g; 12.5 and 14.6mg/g, 9.85 and 18.6mg/g . With lower acidic, iodine and peroxide content as observed in the result, fresh palm oil is more suitable for domestic uses while stored palm oil could find use in the industries.

Keywords : Physicochemical, Iodine, Refractive Index, Peroxide, Ester.
