(57) Abstract: The process of extracting sterol from deordourised distillates which is a by-product during refining
of soya oil from soya seeds, comprising the steps of:
i) subjecting deodourised distillates to undergo physical conversion;
ii) subjecting resultant product at step (i) above to the Molecular Distillation; and
iii) subjecting the residue collected at the end of the Molecular Distillation to chemical purification and
mixing with solvents and simultaneously cooling to a very low temperature to obtain the crystal
precipitates;
iv) filtering the crystal precipitates to obtain end filtrates;
v) mixing and treating the said end filtrates at step (iv) with solvents in a crystalizer to remove all the
remaining fatty acids and the impurities present therein;
vi) heating the treated resultant filtrate to undergo a reflux process continuously for predetermined
specific period thereby dissolving the waxes in a solvent and filtering the wax free crystals;
vii) subjecting the said filtered crystals to another solvent was in a centrifuge to remove any other
impurities present;
viii) subjecting said resultant product at step (vii) above to vacuum drying together with simultaneous
heating to obtain the pure sterol.
