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.
