A process for the separation and recovery of minor components from
vegetable oil such as palm oil. Esterified palm oil is subjected to
molecular distillation giving a concentrate rich in minor components. The
concentrate is then adsorbed to adsorbents such as normal phase silica
gel, reversed phase (particularly C18) silica gel or neutral alumina as
well as polymer absorbents such as polyethylene glycol and polyacrylate
polyalcohol. Minor components such as squalene, carotenes, tocols and
sterols are then selectively desorbed, separated and recovered using
solvents operating at isocratic conditions. The desorption of the said
minor components are sped up by applying pressure of between 0.2 to 50
bar. By the same method, individual tocols isomers from palm oil can also
be separated and recovered.
