Enrichment of unsaturated fatty acids from palm oil by means of solubility difference / Noor Azmira Mohd Alwi

Palm oil undergo saponification process with ethanolic sodium hydroxide to break the triglycerides into free fatty acids (FFA) and glycerol. Then, the FFA was crystallize with methanol by using methanol crystallisation method based on one parameter which is solubility difference. The crystallisation...
