Abstract

The fatty acid composition is a parameter that determines the quality and origin of vegetable oils. The standard method used in the analysis of fatty acid composition is gas chromatography (GC). In the last 20 years, however, the H NMR method has become more important in the analysis of fatty acids. Thanks to no need of special sample preparation, the high speed of analysis and the possibility to automate the process of analysis, H NMR is becoming a popular method of testing vegetable oils. It is possible to test oils both qualitatively and quantitatively, taking into account both the fatty acid profile and the level of minor components. In combination with statistical and chemometric methods, the analysis of H NMR spectra allows one to obtain much valuable information about the tested oil, considering its composition, quality, the presence of impurities, or the origin. The paper presents an overview of publications focusing on the application of the H NMR method in the profiling of fatty acids in vegetable oils.

摘要

脂肪酸组成是决定植物油质量和来源的一个参数。分析脂肪酸组成的标准方法是气相色谱法（GC）。然而，在过去的 20 年中，H NMR 法在脂肪酸分析中变得更为重要。由于不需要特殊的样品制备，分析速度快，并且可以实现分析过程的自动化，因此 H NMR 成为了测试植物油的一种流行方法。它可以定性和定量地测试油，同时考虑脂肪酸的分布和少量成分的水平。结合统计和化学计量学方法，对 H NMR 谱的分析可以获得有关测试油的大量有价值的信息，包括其组成、质量、杂质的存在或来源。本文综述了专注于 H NMR 法在植物油中脂肪酸剖析应用的文献。
