Polyphenols are characterized by different AgroFood by-products and waste sources, hence this book explores the practical applications of these polyphenols in the development of functional foods and pharmaceutical and cosmetic products. Containing definitions, case studies, applications, literature reviews, and coverage of recent developments, this book will be a welcomed resource for food scientists, including those working in sustainability, agriculture and engineering. - Promotes a circular economy by discussing the valorization of these compounds - Features case studies that enable the reader to understand the potential of several polyphenols and the possibilities regarding their incorporation into several matrixes - Presents tools for the development of new lines of research or in support of ongoing investigations with solutions for existing challenges

Polyphenols in Plants assists plant scientists and dietary supplement producers in assessing polyphenol content and factors affecting their composition. It also aids in selecting sources and regulating environmental conditions affecting yield for more consistent and function dietary supplements. Polyphenols play key roles in the growth, regulation and structure of plants and vary widely within different plants. Stress, growth conditions and plant species modify polyphenol structure and content. This book describes techniques to identify, isolate and characterize polyphenols, taking mammalian toxicology into account as well. - Defines conditions of growth affecting the polyphenol levels - Describes assay and instrumentation techniques critical to identifying and defining polyphenols, critical to researchers and business development - Documents how some polyphenols are dangerous to consume, important to dietary supplement industry, government regulators and lay public users

Phenolic compounds are secondary metabolites found in legumes, grains, fruits, algae, leaves and many other dietary sources. However, the abundance and differences in chemical structure, solubility, toxicological safety and, therefore, bioactivity and functional effects in humans. This book covers the basic chemical composition and structure of phenolic compounds and focus on their technological applications in food models and products: nondairy and dairy beverages, bakery, and meat-based foods. Additionally, food preservation aspects, including the effects of polyphenols additions on the product's shelf-life, processing and recovery of polyphenols from plant materials, antioxidant and antiproliferative aspects of polyphenol-rich extracts are considered and holistically debated. - Toxicological safety of polyphenols in foods is explained and discussed - Application of polyphenols in dairy and nondairy foods is discussed - Effects of polyphenols on food preservation/shelf-life are explained

Plant secondary metabolites have been a fertile area of chemical investigation for many years, driving the development of both analytical chemistry and of new synthetic reactions and methodologies. The subject is multi-disciplinary with chemists, biochemists and plant scientists all contributing to our current understanding. In recent years there has been an upsurge in interest from other disciplines, related to the realisation that secondary metabolites are dietary components that may have a considerable impact on human health, and to the development of gene technology that permits modulation of the contents of desirable and undesirable components. Plant Secondary Metabolites: Occurrence, Structure and Role in the Human Diet addresses this wider interest by covering the main groups of natural products from a chemical and biosynthetic perspective with illustrations of how genetic engineering can be applied to manipulate levels of secondary metabolites of economic value as well as those of potential importance in diet and health. These descriptive chapters are augmented by chapters showing where these products are found in the diet, how they are metabolised and reviewing the evidence for their beneficial bioactivity.

The growing concern for human wellbeing has generated an increase in the demand for polyphenols, secondary plant metabolites that exhibit different bioactive properties. This increasing demand is mainly due to the current applications in the food industry where polyphenols are considered essential for human health and nutrition. Advances in Technologies for Producing Food-relevant Polyphenols provides researchers, scientists, engineers, and professionals involved in the food industry with the latest methodologies and equipment useful to extract, isolate, purify, and analyze polyphenols from different available sources, such as herbs, flora, vegetables, fruits, and agro-industrial wastes. Technologies currently used to add polyphenols to diverse food matrices are also included. This book serves a reference to design and scale-up processes to obtain polyphenols from different plant sources and to produce polyphenol-rich foods with bioactive properties (e.g. antioxidant, antibacterial, antiviral, anticancer properties) of interest for human health and wellbeing.

Plant polyphenols are secondary metabolites that constitute one of the most common and widespread groups of natural products. They are crucial constituents of a large and diverse range of biological functions and processes, and provide many benefits to both plants and humans. Many polyphenols, from their structurally simplest representatives to their oligo/polymeric versions, are notably known as phytoestrogens, plant pigments, potent antioxidants, and protein interacting agents. This sixth volume of the highly regarded Recent Advances in Polyphenol Research series is edited by Heidi Halbwirth, Karl Stich, Véronique Cheynier and Stéphane Quideau, and is a continuance of the series’ tradition of compiling a cornucopia of cutting-edge chapters, written by some of the leading experts in their respective fields of polyphenol sciences. Highlighted herein are some of the most recent and pertinent developments in polyphenol research, covering such major areas as: Chemistry and physicochemistry Biosynthesis, genetics & metabolic engineering Roles in plants and ecosystems Food, nutrition & health Applied polyphenols This book is a distillation of the most current information, and as such, will surely prove an invaluable source for chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, biologists, ecologists, food scientists and nutritionists.
