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.
(ZH) 本发明涉及生产具有低杂质水平的脂肪酸烷基酯的方法，所述脂肪酸烷基酯例如脂肪酸甲基酯(FAME)和脂肪酸乙基酯，所述杂质例如磷脂。本发明的方法通过将两个加工步骤组合成一个单一加工步骤而得以简化，因此在经济上更便宜。所述方法包括将水、醇、甘油三酯和/或游离脂肪酸与脂解酶和磷脂酶混合。随后将含有甘油、残余的酶和大多数被水解的磷脂的水相与非水相分离，由此降低非水相中的磷脂含量。
