EXTRACTION AND PHYSICOCHEMICAL CHARACTERISATION OF THE OIL EXTRACT FROM THE SEED OF UMBRELLA TREE (TERMINALIA MENTALIS). [ READ ]
Kayode Ebenezer Samuel.
The increase in demand and different applications of oils foster the search for vegetable and seed oils that are of high quality to meet up with the increasing rate of its demand worldwide. Oils are known to have important biological activities. In this study, the extraction and physicochemical characterization of the oil from the seed of Terminalia mentalis (umbrella tree) was carried out. The physical properties of the oil compares favorably with those of the conventional vegetable and seed oils like cotton seed oil, soybean oil and groundnut oil among others. The results obtained for the chemical properties showed 38% oil yield, 1.5 refractive index, 0.871 g/ml density, 0.052 mgKOH/g acid value, 2.600 mEq/Kg peroxide value, 140.223 mgKOH/g ester value, 54.567 gI2/100g iodine value and 140.275 mgKOH/g saponification value. These make the oil suitable for use in the industry except in the ink and paint industries because of its non drying property which is due to its low iodine value content.
