Abstract | Sequential-cooling ureafatty acid complexation is a novel technique developed to pre-concentrate vitamin E extractedfrom palm fatty acid distillate before further purification by supercritical fluid extraction. The efficacies of the sequential-coolingand the constant cooling methods were compared. The sequential-cooling method cools the reaction mixture to a sequence ofpredetermined temperatures between 35?C and -5?C, whereas the constant cooling method cools down to ?5?C that is maintainedfor 12 hours. The recovery of vitamin E was increased from 21.62% with constant cooling to 32.04% with sequential cooling,while the corresponding concentration in the sample increased from 8.85 to 25.16 % (w/w). Combining sequential cooling ureafatty acid complexation with a final supercritical fluid extraction increased the concentration of vitamin E to 80% |
