Abstract

The objective of the current study was to separate saturated fatty acids (SFAs) from high free fatty acid crude palm oil fatty acid mixture using the methanol crystallisation method. The development of methanol crystallisation method procedure was based on various parameters. The fatty acid composition was determined by using gas chromatography-flame ionisation detector (GC-FID) as Fatty Acid Methyl Esters. The highest percentage of SFAs was more than 89% with the percentage yield of 48.9% under the optimal conditions of the fatty acids-to-methanol ratio of 1:15 (w/v), the crystallisation temperature of -15 °C, and the crystallisation time of 24 hours, respectively. After a double crystallisation, the composition of separated SFAs contains 90% of palmitic acid (C16:0) as a major component and 5.8% of stearic acid (C18:0), respectively. Moreover, almost 4.2% of oleic acid (C18:1) was observed in the saturated solid product. Based on the results, the use of methanol as a crystallisation solvent is recommended because of its high efficiency, low cost, stability, obtainability, and comparative ease of recovery.
