    • 11515.204-WO 25 ABSTRACT The invention relates to a process for producing a triglyceride product comprising the steps of: (a) subjecting a triglyceride feedstock comprising at least 25 mole%, based on the total amount of acyl groups in the triglycerides, unsaturated C18 fatty acid residues to an alcoholy- sis reaction with an alcohol having 1 to 6 carbon atoms (C 1 -C 6 ) to obtain a reaction mixture, 5 wherein the conversion is at least 65%; (b) separating from the reaction mixture produced in step (a) fractions comprising (i) unsaturated C18 fatty acid alkyl esters and (ii) glycerides; and (c) using the fractions (i) and (ii) or subfractions thereof in a condensation reaction catalyzed by a lipase to produce a triglyceride product comprising at least 80 mole% unsaturated fatty acids.10
    • 11515.204-WO 25摘要本发明涉及一种生产甘油三酸酯产品的方法,包括以下步骤:(a)将甘油三酯原料包含至少25摩尔%,基于甘油三酯中的酰基总量,不饱和C18脂肪 酸残基与具有1至6个碳原子的醇(C 1 -C 6)进行醇解反应,得到反应混合物,其中转化率为至少65%; (b)从步骤(a)中产生的反应混合物中分离出包含(i)不饱和C18脂肪酸烷基酯和(ii)甘油酯的级分; 和(c)在由脂肪酶催化的缩合反应中使用级分(i)和(ii)或其亚级分,以产生包含至少80摩尔%不饱和脂肪酸的甘油三酯产物。
