Ethanolysis of PKO has been done by the addition of ethoxide ion solution {ethanol 90% containing 1% (w/w PKO) of NaOH} to 100 g PKO at the ratio of 1.0; 1.2; or 1.4 (w/w), each with the addition of glycerol 10% (w/w PKO) at 55-60oC, stirred at 1000 rpm for 3, 6, 9, or 12 minutes. Careful observation is done on the yield and monoglyceride, diglycerides, and triglycerides distribution patterns in the PKO ethanolysis products. The average yield of all treatments resulted in a value of 44.91% (± 4.47%; w/w). The yield of ethanolysis of PKO with the ratio of 1.4 (w/w) is better than with the ratio of 1.0 (w/w) and 1.2 (w/w), while 6 minutes shown a better result for the PKO ethanolysis time reaction compared to 3, 9, or 12 minutes. The average of glycerides, esters, monoglycerides, internal standard, diglycerides, and triglycerides in overall treatments, shows 6.09, 55.02, 7.07, 2.55, 23.54, and 5.73%, respectively. Group of monoglyceride (MG) and diglyceride (DG) compounds in PKO ethanolysis products, both obtained on average with the best treatment at ethanolysis time for 3 minutes for a ratio of 1.0 (w/w), each at 7.74% (w/w) and 30.60% (w/w).
