Abstract: The present invention provides a method for reducing the level of free fatty acids in biodiesel/fatty acid alkyl esters. The method comprises providing a composition comprising fatty acid alkyl esters, free fatty acids and/or a fatty acid feedstock, reacting said free fatty acids and/or said fatty acid feedstock with alcohol in the presence of one or more liquid lipolytic enzymes to produce fatty acid alkyl esters; and/or reacting the free fatty acids and/or said fatty acid feedstock with alcohol in the presence of one or more non-enzymatic catalysts to produce fatty acid alkyl esters.
