“…The following review can be consulted for further information in this field [44]. The technique was also used recently to separate geometrical and positional C18:1 isomers in foods containing trans FA from both natural and industrial origin [78]. Regarding vegetable oils, some studies are available in the literature approaching UV absorption indirect detection [79,80] and C 4 D [46].…”

Fatty acids determination is of paramount importance for quality control and suitable labeling of edible oils, required by regulatory agencies in several countries, and fast methods for this determination are worldly desired. This review article aimed to explore the available analytical methods for vegetable and marine oils analyses employing CE, which can be a straightforward and faster alternative than GC methods for fatty acid determination, considering some purposes. CE usually offers the possibility of a rapid analysis with a simple preparation of the sample, without requiring specific columns, which are inherent advantages of the technique. Instrumental conditions and the key points about fatty acids determination employing the technique are highlighted, and the main challenges and perspectives are also approached. Potential use of CE for edible oil analyses has been demonstrated for research and routine, which can be of interest for industries, regulatory agencies, and edible oil researchers. Therefore, we have explored the analytical approaches described in the last decades, intending to spread the interest of CE methods for fatty acid monitoring, label accuracy assessment, and food authenticity evaluation of edible oils.

“…The chosen pre-processing method is determined by the nature of the data, and should be explored [56]. Three issues were raised in a recent review [57]; i.e., (1) incorrect units for exploratory analysis, (2) misinterpretation of PCA loadings from a first-and secondderivative pre-processed signal, (3) artefacts caused by signal normalization procedures, such as SNV or MSC, leading to the misinterpretation of PCA loadings. As a remedy to these issues, the units employed should be directly connected to the concentration to minimize misinterpretations.…”

Since ancient times, herbal medicines (HM) have played a vital role in worldwide healthcare systems. It is therefore critical that a thorough evaluation of the quality and control of its complicated chemical makeup be conducted, in order to ensure its efficacy and safety. The notion of HM chemical prints, which aim to acquire a full characterization of compound chemical matrices, has become one of the most persuasive techniques for HM quality evaluation during the last few decades. The link between NMR and chemometrics is discussed in this article. The chemometric latent variable technique has been shown to be extremely valuable in inductive studies of biological systems as well as in solving industrial challenges. The results of unsupervised data exploration utilizing main component analysis as well as the multivariate curve resolution, were various. On the other hand, many contemporary NMR applications in metabolomics and quality control are based on supervised regression or classification analyses.

“…Besides, some trans ‐FA can be also naturally found in milk and dairy products, derived from bacterial hydrogenation of FA in the rumen of animals. In this context, a new CZE‐UV method has been recently developed to detect both elaidic acid, an industrial‐related trans ‐FA, and vaccenic acid, a natural trans ‐FA, in spreadable cheese, and proposed for the detection of the addition of hydrogenated vegetable fat to food [52]. The method used a BGE composed of 10 mmol/L heptakis (2, 3, 6‐tri‐ o ‐methyl)‐β‐CD, 24 mmol/L sodium tetraborate buffer solution, 45% methanol, and 15% acetonitrile and provided LODs as low as 0.0163 and 0.0169 mmol/L for elaidic and vaccenic acids, respectively.…”

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.
