Secondary metabolites, including polyphenols, alkaloids, and terpenoids, provide food products with pigmentation, health benefits, and sensory attributes. These compounds may lend disease protection to botanicals and supplements, and, specifically in the case of polyphenols, enhance the quality of foods and beverages, such as tea, wine, and beer. Polyphenols’ significance for the human diet and antimicrobial activity has been recently established. In this Research Topic, the role of polyphenols for fraud and authenticity issues (e.g., geographical origin, organic–non organic) via metabolomics and foodomics will be discussed. Additionally polyphenols as natural ingredients can be considered as alternatives to chemical preservatives due to antioxidant and antimicrobial activity.
The goal of this Research Topic is therefore to provide new research on polyphenols concerning methods of extraction and isolation, chemical analysis and characterization via modern and hyphenated analytical techniques, such as mass spectrometry (multiple quadrupole (LC-MSn), time of flight (QTOF) LTQ-Orpitrap), with two-stage mass analysis (MS/MS) and multi-stage mass analysis (MSn), GC-MS after silylation and NMR spectroscopy (i.e., 2D Diffusion Ordered Spectroscopy) in combination with chemometrics. The health promoting effects of polyphenols is also important, hence our goal is to collect all of the available scientific research on the discovery of new polyphenolic compounds via hyphenated analytical techniques from all kinds of foods, beverages, and natural products, which could benefit human health.
We welcome subtopics in including (but not limited to):
1. Modern, new, "green" extraction techniques for extracting and isolating polyphenols;
2. Analysis and chemical characterization by means of new, hyphenated techniques;
3. Metabolomics and Foodomics correlated to fraud and authenticity issues;
5. Antioxidant and antimicrobial activity of foods due to polyphenols;
6. Waste recovery of polyphenols and analytical determination.
