“…On the other hand, CE provides very fast methods for detecting particular groups of FA. This approach was followed for the determination of the major unsaturated FA present in milk, that is, C18:1 n-9 cis, C18:2 n-6, and C18:3 n-3, and applied to the study of different milk powder samples packaged with different oxygen concentrations [47]. The developed methodology offered a great sensibility and was useful to evaluate the potential lipid oxidation that occurred as a consequence of the presence of oxygen in the sample packages.…”

This work presents a revision of the main applications of capillary electromigration methods in food analysis and Foodomics. Articles that were published during the period February 2019‐February 2021 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods. Namely, CE methods have been applied to analyze amino acids, biogenic amines, carbohydrates, chiral compounds, contaminants, DNAs, food additives, heterocyclic amines, lipids, secondary metabolites, peptides, pesticides, phenols, pigments, polyphenols, proteins, residues, toxins, vitamins, small organic and inorganic compounds, as well as other minor compounds. The last results on the use of CE for monitoring food interactions and food processing, including recent microchips developments and new applications of CE in Foodomics, are discussed too. The new procedures of CE to investigate food quality and safety, nutritional value, storage and bioactivity are also included in the present review work.

“…The reported analytical methods for FAs include CE [18], NMR [19], GC [20], GC-MS [21,22], LC [23], and LC-MS [24,25]. Due to high sensitivity and excellent separation, GC-MS is widely used to determine SCFAs and MCFAs in biological samples.…”

Fatty acids have multitudinous biological functions and play a crucial role in many biological processes, but due to poor ionization efficiency and lack of appropriate internal standards, the comprehensive quantification of fatty acids by liquid chromatography‐tandem mass spectrometry is still challenging. In this study, a new, accurate, and reliable method for quantifying 30 fatty acids in serum using dual derivatization was proposed. Indole‐3‐acetic acid hydrazide derivants of fatty acids were used as the internal standard and indole‐3‐carboxylic acid hydrazide derivants of them were used to quantify. The derivatization conditions were systematically optimized and the method validation results showed good linearity with R2 > 0.9942, low detection limit (0.03–0.6 nM), precision (1.6%–9.8% for intra‐day and 4.6%–14.1% for inter‐day), recovery (88.2%–107.2% with relative standard deviation < 10.5%), matrix effect (88.3%–105.2% with the relative standard deviation < 9.9%) and stability (3.4%–13.8% for fatty acids derivants in 24 h at 4°C and 4.2%–13.8% for three freeze‐thaw cycles). Finally, this method was successfully applied to quantify fatty acids in serum samples of Alzheimer's patients. In contrast to the healthy control group, nine fatty acids showed a significant increase in the Alzheimer's disease group.
