ABSTRACT:
A novel impregnated activated carbon, containing from about 1.0 percent to about 15.0 percent by weight of MgO, has been found to be useful in a method of decolorizing a crude vegetable oil or a degummed vegetable oil, and removing organic acids therefrom, as well as in a process for making a refined edible vegetable oil wherein a crude vegetable oil is degummed, passed through the impregnated activated carbon, and subjected to steam distillation at reduced pressure. A novel method of preparing the MgO impregnated activated carbon has also been discovered.
