The proximate nutritional composition, characterization some selected of physicochemical properties and comparative assessment of Trichilia emetica oilseeds with some selected commercial oilseeds were compared in this study. The results revealed the percentage crude lipid, crude fiber, ash, crude protein, and total carbohydrate contents of the oilseeds as 65.81, 15.28, 3.4, 5.21, and 22.43, respectively. The oil is odorless and solid at room temperature, with golden yellow color. The acid value (8.13 mgNaOH/g), saponification value (180.09 mgKOH/g), iodine value (60.15 mgI2/g) and peroxide value (0.56 meqO2/kg) of the seeds oil. The studied characteristics of the seeds oil was compared favorably with most conventional vegetable oils and seeds oil. The results suggest that the seeds examined may be nutritionally potent and also viable source of seeds oil judging by the oil yield. The data also showed that the seeds oil was edible inferring from the low acid value. Industrially, the results revealed the seeds oil has a great potential in cosmetic, candle and soap making industries because of the high saponification value. It was also shown that to be non-drying due to low iodine value which also suggested that the oil contain few unsaturated bonds and therefore have low susceptibility to oxidative rancidity and deterioration as confirmed by the low per oxidation value which serves as indicators of the presence or high levels of anti-oxidants in the oil.
Key words: Proximate composition, trichilia emetica oil seeds, physico-chemical.
