Fig. 1. Percent content (%) of the fatty acid group in “Minyak ala Muncar”
There are several methods of separating fatty acids in the oil, namely freezing methods, enzymatic lipase reactions [29], [30], super critical fluid extraction [31], [32], Preparative HPLC with stationary phases modified using AgNO3 reagents [32], [33], crystallization with ethanol solvents [31], n-hexane and ethyl acetate in cold temperature conditions [32], [33], and urea crystallization [16], [32]. However, crystallization methods were the best choice to be applied to recycle MAM. The results of the crystallization process can be seen in table 1.
