Notes:
The seeds of the baobab Adansonia suarenzensis (Bombacaceae) contain 46.2% oil used for cooking by the malagasy population. This oil gives a positive Halphen test showing the presence of cyclopropenoic fatty acids (CPEFA). Composition analysis of derivatized fatty acid methyl esters was done by gas-liquid chromatography (GLC). The A. suarenzensis seed oil contains mainly palmitic (46%) stearic (3.5%) oleic (21%) and linolenic (12%) acids. Effect of heat on CPEFA content of boabab oil was studied at 133°C and 180°C. Major decomposition of CPEFA at 180°C shows that deodorisation would be the main step in the oil refining process. Hydrogenation of the baobab oil using an industrial hydrogenating catalyst results in CPEFA content decreasing rapidly.
