Abstract

CPO refining process generally consisted of degumming, bleaching, filtration, deodorizing and fractionation. At the end of the process, the yield is divided into two products, namely olein (liquid fraction) and stearin (solid fraction). The aims of this research was to study the difference of stirring speeds on synthesis of MDAG using glycerolysis method at laboratory scale. The stirring speed was performed at scale 3 and 4, while MDAG was synthesized at substrate ratio of stearin:glycerol (1:2.3), temperature reaction of 180°C, time reaction of 90 min, and addition of 0.5% NaOH. Formation of MAG and DAG, as well as decomposition of TAG, was found to follow reaction order 0, with R2 of 0.4053, 0.5833, dan 0.3588, respectively. In the use of scale 3, formation of MAG and DAG followed reaction order 0, whereas decomposition of TAG followed reaction order 1, resulting in R2 of 0.6551, 0.6114, and 0.7708, respectively. At verification stage, the results demonstrated high accuracy, with Coefficient of Variance (CV) of < 5%, resulting in MAG 0.56% and DAG 2.52%. Acylglycerol fractions of verified MDAG product showed a noticeable variety, i.e. MAG 46.68±0.26%, DAG 32.57 ± 0.82%, and TAG 6.78 ± 0.47%. Furthermore, physichochemical characteristics of MDAG showed the greatest proportion of fatty acid as follows: palmitic acid (C16: 0) 55.71±0.41% and oleic acid (C18: 1 cis) 29.48±0.15%, with moisture content 0.57±0.02%, FFA 1.91±0.07%, iod number 6.08±0.04 mg/g, and slip melting point at 48.5-50 °C.
