ABSTRACT:
The present invention relates to improved methods for refining vegetable oils. Vegetable oil is combined with organic acid and subjected to high shear to finely disperse the acid solution in the oil. The resulting acid-and-oil mixture is mixed at low shear for a time sufficient to sequester contaminants into a hydrated impurities phase, producing a purified vegetable oil phase.
