ABSTRACT

It is shown that monoglycerides can be selectively adsorbed on rice husk ash from crude palm oil-hexane miscella or crude palm oil. The adsorbed monoglycerides were identified by gas chromatography and GC/MS. The major fatty acids of the monoglycerides were found to be palmitic and oleic acids. In model experiments, 0.2%(w) of monopalmitin added to refined, bleached and deodorized palm olein could be removed completely using rice husk ash; about 48 m mol or 15.84 mg of monopalmitin were adsorbed by one gram of ash.
