    • The invention relates to a first process for production of fatty acids directly from any soapstock generated in the alkali refining process comprising of a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of mono-,di- and triglycerides without prior neutralisation b) neutralizing and splitting the soaps with strong acids until reaching pH 1-6, c) separating the fatty acid phase from the aqueous by settling and/or centrifugation. In a second embodiment a second process for production of fatty acids directly from any soapstock is subject of the invention. This process comprises i) neutralizing and splitting the soaps with strong acids until reaching pH 1-6 ii) adding a lipase to facilitate mono-/di-/triglyceride hydrolysis iii) separating the fatty acid phase from the aqueous by settling and / or centrifugation In a further subject matter the invention deals with the use of said fatty acids for enzymatic or chemical synthesis of C1 to C6 alcanol esters and / or for chemical dimerisation of the fatty acids. As a consequence the invention also refers to a process for obtaining sterolesters and/or fatty acid esters characterized in that the fatty acids obtained according to the processes for production of fatty acids directly from any soapstock as aforementioned described are a) esterified with C1 to C6 alkanol with a Lipase that is selective for fatty acids and does not transesterify the sterolesters b) the fatty acid esters are separated from the sterolesters by distillation The use of said sterolesters for animal feed, food, health foods and as pharmaceutical agent for lowering cholesterol and/or as precursor for steroid synthesis as well as the use of said fatty acid esters as solvent, for the production of fatty alcohols, as biofuel, and biodiesel, as plastisicer or for dimerization is also subject of the invention.
    • 本发明涉及直接从碱精制方法中生产的任何皂液生产脂肪酸的第一种方法,包括:a)直接向碱性皂料中加入脂肪酶,以促进甘油单酯,甘油二酯和甘油三酯的水解,而无需预先中和b) 用强酸中和和分解肥皂直至pH达到1-6,c)通过沉降和/或离心将脂肪酸相与水相分离。 在第二个实施方案中,直接从任何皂片生产脂肪酸的第二种方法是本发明的主题。 该方法包括:i)用强酸中和并分离肥皂直到达到pH 1-6 ii)加入脂肪酶以促进单 - /二 - /甘油三酯水解iii)通过沉降和/或离心将脂肪酸相与水相分离 在另一主题中,本发明涉及所述脂肪酸用于C1至C6烷醇酯的酶或化学合成和/或用于脂肪酸的化学二聚化的用途。 因此,本发明还涉及一种获得甾体和/或脂肪酸酯的方法,其特征在于根据如上所述直接从任何皂片生产脂肪酸的方法获得的脂肪酸是a)用C1至C6酯化 链烷醇具有对脂肪酸选择性且不酯交换酯基的脂肪酶b)脂肪酸酯通过蒸馏与甾体分离使用所述甾体为动物饲料,食品,保健食品和用作降低胆固醇的药剂, /或作为类固醇合成的前体以及使用所述脂肪酸酯作为溶剂,用于生产作为生物燃料的脂肪醇和作为增塑剂的生物柴油或二聚体也是本发明的主题。
