KEYWORDS: Breadnut (Artocapus altilis) seed oil, specific gravity, physicochemical properties.


Some physical and chemical properties of breadnut (Artocarpus altilis) seed oil were investigated. The oil was found to be pale-yellow in colour and thick, but not solid at room temperature. It sets at 11.3° C and melts at 42.3°C, has specific gravity of 0.82 and a refractive index of 1.46 at 40°C. The total oil content of the seed was found to be 4.64%. The oil had an unsaponifiable matter content of 2.93% and a saponification value of 238.43. The iodine value was 46.83, while the acid and peroxide values were 1.15 and 14.6, respectively. The free fatty acid content of the oil was 1.89% . Although the oil has some advantageous physicochemical properties, this sample is not an oil seed because of its very low crude fat content.
