Shea Butter Quality Study in Three African Countries
The purpose of the experiment was to comprehensively investigate the oil quality of shea butter in Ghana,Uganda and Burkina Faso.The composition and quality of shea butter in the three countries were investigated by physicochemical property comparison,gas chromatography-mass spectrometry analysis,and high performance liquid chromatography analysis of triglyceride composition.The results showed that the yield of oil in Uganda was the highest(51.82%),and the content of Ghanaian shea butter was lower in acid value,moisture,peroxide value,insoluble impurities,and higher in unsaponifiable substances,and 12 fatty acids were detected by gas chromatography-mass spectrometry,among which oleic acid,stearic acid,linoleic acid and palmitic acid were the three main fatty acids of shea butter,and the total content of these four fatty acids exceeded 95%high performance liquid chromatography showed that SOS and SOO were the main triglycerides of the three shea butters,and Uganda shea butter had more OOO triglycerides,which were more than 6 times higher than those in the other two countries.In summary,Ghanaian shea butter has better oil quality,while the high unsaturated fatty acid and high OOO content of Uganda shea butter also broadens the application range of shea butter.
