Characterisation of some underutilised vegetable oils and <strong>the</strong>ir evaluation as starti<br />

Abstract<br />
Oils were extracted from <strong>the</strong> inner skin of <strong>Strychnos</strong> madagascariensis fruit shell, Trichelia emetica<br />
seed and Ximenia caffra seed. Gas chromatography analysis of methyl esters of <strong>the</strong> glycerides of<br />
<strong>the</strong>se oils was used to determine <strong>the</strong> fatty acid profiles of <strong>the</strong> oils. S. madagascariensis and X. caffra<br />
oils were found to contain high oleic acid levels, 68 and 59% respectively, while T emetica oil was<br />
found to contain 53% palmitic acid. Pancreatic lipase digestion was used to per<strong>for</strong>m structural<br />
analyses on <strong>the</strong> triglycerides of oils. Oleic acid was found to be concentrated at <strong>the</strong> 2-position of <strong>the</strong><br />
triglycerides of <strong>the</strong> X caffra and T emetica oils. The three oils were evaluated <strong>for</strong> use as starting<br />
materials in lipase-catalysed production of cocoa butter equivalents using transesterification<br />
reactions. A 1,3-specific lipase from Rhizomucor miehei was used to incorporate stearic acid and<br />
palmitic acid into <strong>the</strong> 1- and 3-positions of <strong>the</strong> triglycerides. The products of <strong>the</strong> transesterifications<br />
in <strong>the</strong> case of X caffra and S. niadagascariensis compare well with those produced using lipasecatalysed<br />
transesterifications of o<strong>the</strong>r oils. (C) 2002 Elsevier Science B.V. All rights reserved.
