Vegetable oils are a dietary source of lipids that constitute an essential component of a healthy diet. The commonly used vegetable oils differ significantly for their triacylglycerol (TAG) profile. TAGs represent the principal components of oils and may contain different fatty acids (FA) esterified with glycerol leading to several positional isomers. To differentiate individual TAGs species in edible oils, advanced analysis systems and innovative methods are therefore required. TAGs can be considered as good fingerprints for quality control and many studies have been performed to develop rapid and low cost analytical methods to determinate the authenticity, origin and eventually evidence frauds or adulterations. The present manuscript provides a general overview on the most common vegetable oils TAGs compositions and on the related analytical methodologies recently used. Finally, the chemometric applications developed to assess the authenticity, quality and botanical origin of various edible oils are discussed.
植物油是脂质的饮食来源，是健康饮食的重要组成部分。常用植物油的三酰甘油（TAG）谱差异很大。TAG是油的主要成分，可能含有与甘油酯化的不同脂肪酸（FA），从而产生几种位置异构体。因此，为了区分食用油中的单个TAG种类，需要先进的分析系统和创新方法。TAG可被视为质量控制的良好指纹，并且已经进行了许多研究来开发快速且低成本的分析方法，以确定其真实性、来源，并最终证明是否存在欺诈或掺假行为。本手稿概述了最常见植物油的TAG组成以及最近使用的相关分析方法。最后，讨论了为评估各种食用油的真实性、质量和植物来源而开发的化学计量学应用。
