Progress in Pretreatment and Analysis of Fatty Acids in Foods: An Update since 2012

Abstract

Fatty acids (FAs) are a class of lipids found in everyday foods that are closely related to human health. These chemicals are involved in many physiological functions. The establishment of methods for the analysis of FAs in different foods is necessary. In this review, an updated overview of the pretreatment and analysis methods that have been reported since 2012 is given. Sample preparation methods involve extraction, fractionation and derivatization, while analysis methods involve chromatographic, spectral, and electrophoretic methods, as well as several other methods. Different pretreatment and determination methods are discussed.
