Abstract
The content of phosphorus-containing components and the iron content of an edible vegetable or animal oil, preferably an oil such as soybean oil which has been wet-refined to remove mucilage, are reduced by enzymatic decomposition by contacting the oil with an aqueous solution of phospholipases A.sub.1, A.sub.2, or B and then separating the aqueous phase from the treated oil.
