Abstract: The present invention provides a method for reducing the content of phospholipids in a phospholipid-containing oil material by converting the phospholipids into fatty acid alkyl esters (FAAE) and free fatty acids (FFA). The method comprises reacting a phospholipid-containing oil material with one or more phospholipases in a system comprising a low content of a short chain alcohol and water. The method can be used in degumming or as an enzymatic pretreatment before transesterification and/or biodiesel production, but it can also be used as basic oleochemical in further downstream processes of the oleochemical industry. The present invention also provides a method for producing free fatty alkyl esters (FAAE) from phospholipids in a phospholipid containing oil material by reacting the phospholipids with one or more phospholipases in a reaction mixture comprising a low content of a short chain alcohol and water.
