Abstract
(EN)


The present invention relates to a method for producing fatty acid alkyl
esters, such as fatty acid methyl esters (FAME) and fatty acid ethyl esters
with a low level of impurities such as phospholipids. The method of the
invention is simplified by combining two process steps into one single process
step and is therefore economically cheaper. The method includes mixing water,
alcohol, triglyceride and/or free fatty acids a lipolytic enzyme and a
phospholipase. Subsequently the aqueous phase, which contains glycerine,
residual enzyme and most of the hydrolyzed phospholipids, is separated from
the non-aqueous phase, whereby the content of phospholipids in the non-aqueous
phase is reduced.
