IMPROVED METHOD FOR REFINING VEGETABLE OIL

摘要

The present invention relates to improved methods for refining vegetable oil s and byproducts thereof. In an organic acid refining process, vegetable oil is combined with a dilute aqueous organic acid soluti on 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.
