Abstract
Characterization of fats and oils is important in assessing their potential economic uses. This study was carried out to determine and compare the physicochemical characteristics of a commercial oil and solvent extracted oil from the kernels of calabash seeds (Lagenaria siceraria). The range of physicochemical properties are: Solvent extraction recorded a higher yield of (42.3±0.66%) acid value (9.4±1.8 - 8.2±0.5 mgKOH/g of oil), iodine value (4.56±2.6 - 4.46±0.07 mg/100g), saponification value (162.7±4.58 - 159.42±3.68 mgKOH/g), peroxide value (6.0±1.63 - 5.3±2.4 mEq/kg), free fatty acid (10.3±1.76 - 9.89±1.8 % as oleic acid). The low iodine value indicates a high degree of saturation of the fat as well as its non-drying nature.
Keywords: Chemical, analysis, Lagenaria siceraria, calabash seed oil.
