When a mixture of triacylglycerols and free fatty acids or fatty acid alkyl esters is treated with a random or sn‐1,3 regioselective lipase enzyme, part of these acids will be incorporated into the triacylglycerols while liberating fatty acids that were originally part of these triacylglycerols. Authors generally report the extent of incorporation and then comment on whether equilibrium had been reached and/or acyl migration has been observed. In doing so, they do not refer to articles that provide equations to be used to conclude whether equilibrium has been reached. It is the purpose of the present article to provide these equations and, by using them on literature data, show to what extent conclusions drawn by authors are correct. Besides, the availability of these equations will make it easier to interpret ongoing research on interesterification and to steer its direction in a more appropriate manner.

酶法酯交换反应中脂肪酸掺入的预测

当用无规或sn-1,3区域选择性脂肪酶处理三酰甘油和游离脂肪酸或脂肪酸烷基酯的混合物时，这些酸的一部分将被掺入三酰甘油中，同时释放出原来是这些三酰甘油一部分的脂肪酸。作者通常报告掺入的程度，然后评论是否达到平衡和/或观察到酰基迁移。这样做时，他们没有引用提供方程式以推断是否已达到平衡的文章。本文的目的是提供这些方程，并通过在文献数据中使用它们，显示出作者得出的结论在何种程度上是正确的。除了，
