Physicochemical Properties of Some Vegetable Seed Oils and Their Applications | Chapter 06 | New Insights on Chemical Research Vol. 1
The physicochemical properties of oils were discussed, and as a case study, extracted from three locally available plant seeds in Nigeria namely: Alchomea cordiforlia, Cyperus esculentum and Irvingia gabonensis using n-Hexane and their properties determined. The results of the analysis revealed that their % yield were 37.00, 27.50 and 33.00 for A. cordiforlia, C. esculentum and I. gabonensis respectively. Their odour was non-offensive and their colours were reddish, light yellow and milky white for A. cordifolia, C. esculentum and I. gabonensis respectively, making them bright and attractive. The specific gravity of the oils at 25°c was 0.91, 0.94 and 0.92 for A. cordiforlia, C. esculentum and I. gabonensis respectively. Their flash points in °c were also 155, 159 and 229 respectively, indicating that I. gabonensis is the most thermally stable oil and suitable for frying. The chemical properties for A. cordiforlia, C.esculentum, and I. gabonensis respectively were as follows: Acid v...
