Separation/fractionation of triglycerides in terms of fatty acid constituents in palm kernel oil using supercritical CO2

Separation/fractionation of triglycerides in terms of fatty acid constituents in palm kernel oil using supercritical CO2

Separation of triglycerides in terms of fatty acid constituents in palm kernel oil (PKO) from dehulled ground palm kernel using supercritical carbon dioxide (SC-CO2) as a solvent at 40 and 80 ◦C and pressures of 20.7, 27.6, 34.5, 41.4 and 48.3MPa was studied. The extraction was continuous and PKO...

Triglycerides with differing fatty acid contents of caprylic (C8), capric (C10), lauric (C12), myristic (C14), palmitic (C16), stearic (C18:0), oleic (C18:1) and linoleic (C18:2) acid were separated in different percentages in different fractions. About 70% of PKO comprises triglycerides with C8–C12 fatty acids and these fatty acids were mostly extracted in fractions 1and 2.
