Polyphenols: Physicochemical and Biological Properties and Perspectives of Their Use in a Zero-Waste Society.

The 28th International Conference on Polyphenols, held in Vienna (Austria) in July 2016, offered a venue for global exchanges on the active research on polyphenols and for the presentation and discussion of the latest advances. The multidisciplinary event attracted 280 scientists from four continents working in different fields, from analytical and biosynthetic chemistry through genetic and metabolic engineering, plant physiology, and ecology to food nutrition and health sciences as well as industrial applications. This special issue presents a selection of papers from oral presentations and poster contributions shown within the framework of sessions focusing on research in the fields of (1) chemistry and physicochemistry, (2) food, nutrition, and health, and (3) applied polyphenolics. This introductory paper also briefly summarizes general properties of this versatile and largest group of secondary metabolites and their use in bioeconomical approaches.
