Characteristics of menhaden oil ethanolysis by immobilized lipase in supercritical carbon dioxide
E-mail:
Ethanolysis of menhaden oil was performed with 1,3-regiospecific lipase to produce diglycerides and monoglycerides containing polyunsaturated fatty acids, and fatty acid ethyl esters. Immobilized lipases like lipozyme TL-IM (Thermomuces lanuginosa immobilized on silica gel) were used for enzymatic ethanolysis. Ethanolysis was carried out in different processes (solvent free, organic solvent and supercritical fluid system) to compare the reaction rate and yield obtained by menhaden oil ethanolysis. Organic solvent (hexane) and supercritical carbon dioxide (SC-CO2) were used as reaction medium. The reaction products were analyzed by gas chromatography (GC), thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). Higher amounts of ethanol as a substrate caused substrate inhibition which dramatically decreased the reaction rate of ethanolysis. To elucidate the effect of pressure, enzymatic ethanolysis was performed in SC-CO2 at pressures ranging from 75 to 121 bar. Enzymatic ethanolysis of menhaden oil in SC-CO2 decreased by substrate inhibition. Reaction rate and optimum amount of ethanol used were depended on SC-CO2 density individually. Kinetic model with substrate inhibition (dead-end inhibition) by excess ethanol was set up to measure the reaction and inhibition rates.
