Abstract


Jatropha curcas oil (JCO) is non-edible due to the content of phorbolesters (PEs) which are very toxic. The aim of this study was to evaluate the potential of JCO, treated by ultraviolet irradiation combined with ethanol washing, as an edible oil. The results showed that PEs can be significantly decreased by 100% (p < 0.05), but the treatments produced no significant changes (p < 0.05) in the fatty acids composition (FAC) and triacylglycerols (TAGs) in the detoxified Jatropha curcas oil (DJCO). In addition, the quality of DJCO was improved with enhanced DPPH radical scavenging. Therefore, DJCO with good quality will become a good resource for edible oil.
