Abstract

The Carica papaya seed oil (CPSO) was extracted by solvent process. The physicochemical characteristics of the oil were studied. The seed has an oil yield of 31.60% which is commercially sustainable. The CPSO was analysed for specific gravity (0.94), viscosity at 40 0C (49.20 cp), iodine value (53.80 g/100g), and saponification value (158.60 mg/g), peroxide value (6.70 m mol/kg), calorific value (44.37 MJ/kg) and free fatty acid (0.34) using standard methods. Fatty acid profile of the oil indicted it is highly unsaturated (67.4%), this implies that the unsaturated fatty acid of the seed oil is more than the saturated one. The implication of this is that the oil will not solidify easily when applied in engines but will flow as oil and not fat. Thus, it can be concluded that the seed can be utilized for the extraction of oil which can be used as feedstock for bio-fuel production
