摘要：Mono-diacylglycerol (M-DAG) is one of potential palm oil derived products to be developed.Palm Fatty Acid Distillate (PFAD) and glycerol esterification using Methyl Ester Sulfonic Acid (MESA) catalyst produced M-DAG that consist of Free Fatty Acid (FFA) and Triacylglycerol (TAG) fractions.FFA and TAG fractions can reduce the M-DAG emulsifier quality.Therefore,purification process is needed to eliminate FFA and TAG fractions.The purpose of this research was to improve the M-DAG emulsifier quality by purification process.The purification was performed in two ways: solvent extraction - saponification and molecular distillation.Solvent extraction - saponification was done with the addition of 0,10,15 and 20% (w/w) NaHCO3.The result showed that the addition of 20% (w/w) NaHCO3 was the best treatment.It was able to produce 43.52% yield of M-DAGconsisted of 44.48% Thin-Layer Chromatography (TLC) in FFA+TAG composition,31.05% MAG,24.47% DAG,melting point of 44.83oC,free fatty acid level of 19.43%,pH value of 6,emulsion stability of 51.21% for 12 hours,has a white color,dry texture,and odorless.The molecular distillation at temperature of 100-180oC on purification process was carried out to separatethe FFA.Molecular distillation had produced distillate and residue.Molecular distillation was an effective process to separate the FFA from M-DAG whereas produced 96.09% of FFA from distillation flow.
