title = "The effect of different organic solvents on ethyl oleate from palm oil transesterification using immobilized Candida rugosa lipase on Fe3O4-polydopamine nanoparticles",
abstract = "Ethyl oleate ester can be produced by palm oil transesterification. Enzymatic transesterification reaction can be performed by using immobilized Candida rugosa lipase on Fe3O4-polydopamine. The obtained loading percentage of immobilized lipase was 78%. Fe3O4-polydopamine nanoparticles was succesfully characterized using FE-SEM, VSM, and XRD. Variation of solvents used for reaction were t-butanol, methyl isobutyl ketone, and n-hexane. Analysis of ethyl oleate ester was performed by GC-FID. The highest composition on transesterification using free lipase and immobilized lipase, with methyl isobutyl ketone as solvent, were 80% and 54%, respectively. Immobilized enzyme in this reaction can be used repeatedly for three reation cycles reaction with a relative activity decrease of 61%.",
