Abstract
Oil extraction using CO2 from sheanut kernel (Vitellaria paradoxa Gaertn.) and Canarium pulp (Canarium Schweinfurthii Engl.)has been studied in comparison with hexane extraction. Samples that were stored at 18 C and -33 C, were analyzed after 1 month, 1 year and 2 years. Results showed that the extraction yields varied (dry basis) from 17.43-39.57% for shea butter and from 16.10-40.45% for Canarium oil. Lipids extracted with CO2 gave highest acid values, but lowest iodine values what irrespective of the storage temperature. Shea butter analysis by gaseous phase chromatography indicated a composition in stearic and oleic acids that did not vary significantly. Butter extracted with supercritical CO2 from sheanut kernel stored at 18 C were rich in polyunsaturated fatty acid. These results suggest that greater investigations on supercritical CO2 extraction of these fatty materials should be encouraged because of its selectivity.
