The book will be of significant interest to academic and industry researchers who wish to familiarize themselves with the concepts and applications of science and engineering of polyphenols. A book to wrap the developments in detailed synthetic reactions mechanism and industrial applications is broad overdue and present will be a milestone in the field. Topics include Fundamentals of Polyphenols, Synthesis and Characterization, Structure (electronic and Molecular) and Reactivity of Polyphenols, Conversion of Phenolic Compounds, Plant-Based Polyphenols, Polyphenols-Biomolecules Interactions, Biochemistry of Polyphenols, Toxicity and Eco-Friendliness of Polyphenols, Antioxidant Property of Polyphenols, Dietary polyphenols and their role in health and disease, Treatment of Wastewater & Industrial Influents, and applications of polyphenols.
