Abstract

The specific purpose of this scientific article is to obtain scientific information about the pattern composition of monoglycerides (MG), diglycerides (DG) and triglycerides (TG) in palm kernel oil (PKO) ethanolysis products at three stages and of the mole ratios of ethanol in ethoxy solution (ethanol 90% - NaOH 1%) to PKO (assumed as trilaurin). Ethanolysis reactions of PKO had been carried out in three stages, as follows: Level I ethanolysis was carried out at 60°C, at a stirring speed of 1000 rpm for 3 mins, in the treatment of the mole ratios of ethanol in ethoxy solution (ethanol 90% - NaOH 1%) to PKO of the 10, 12, 14, 16, 18 and 20, resulting in ethanolysis product I and the residual reaction I. Level II ethanolysis was ethanolysis of the residual reaction I, resulting in ethanolysis product II and residual reaction II. Level III ethanolysis was ethanolysis of the residual reaction II, resulting in ethanolysis product III. The mean yield of all treatments for PKO Ethanolysis Levels I, II, and III were 12.26±0.46%, 11.20±2.61%, and 11.78±2.99% (w/w), respectively. The highest total yield of PKO ethanolysis level I, II, and III was 41.04±9.74% (w/w) from the mole ratio treatment of 20, while the lowest yield was 27.54±3.39%; (w/w) from the mole ratio treatment of 10. The average amount of MG, DG, and TG from all treatments were 9.740%, 12.801%, and 2.675%, respectively. The highest MG content was obtained from the mole ratio treatment of 20 at Ethanolysis Level I (11.83%).
