Book Description
"Polyphenolics are compounds found in plants, such as phenolic acid and flavonoids, that have positive effects on human health and help fight disease. As such, studies of these compounds are valuable for those looking to improve their own health or the health of others. Chapter One addresses the role that polyphenolics plays in the assessment of food integrity and authenticity. Chapter Two studies the potential of regular long-term consumption of various fruit species for reducing diabetes mellitus. Chapter Three provides a platform for the selection of solvent for extraction, column and mobile phase for better separation of polyphenol compounds. Chapter Four presents extraction with subcritical water as a technique for polyphenol isolation. Lastly, Chapter Five attempts to bridge the gap between the different ethnomedical and folklore claims of utilization of Amaranth germplasms against degenerative diseases with matching polyphenol-based chemical data having antioxidant and anti-inflammatory properties"--

Book Description
Polyphenols make a vital contribution to the colour, tanning, taste and astringency of so many of society's favourites - from the unique taste of the British cup of tea to a glass of red wine. Found widely in many foods of plant origin, polyphenols are also becoming increasingly recognised as antioxidants in the body, with action on long-term health and reduction in the risk of chronic disease. Due to the importance of polyphenols, it is vital to conduct accurate and sensitive analysis. Providing detailed state-of-the-art research, presented in a practical and effective way, Methods in Polyphenol Analysis looks at the latest techniques in this developing field and includes, among others: New modern techniques, such as LC-MS, LC-NMR and LC-coulometric detection; Chemical and enzymatic synthesis of polyphenol conjugates; and Characterization of oligomeric and polymeric tannins and complex polyphenols. This timely publication is written by highly experienced practitioners in this field and will be invaluable to all academics and industrialists involved in phytochemistry, biochemistry and food science.

Book Description
This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.

Book Description
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.

Book Description
Plant polyphenols are secondary metabolites that constitute one of the most common and widespread groups of natural products. They express a large and diverse panel of biological activities including beneficial effects on both plants and humans. Many polyphenols, from their structurally simplest representatives to their oligo/polymeric versions (also referred to as vegetable tannins) are notably known as phytoestrogens, plant pigments, potent antioxidants, and protein interacting agents. Sponsored by the scholarly society Groupe Polyphénols, this publication, which is the fourth volume in this highly regarded Recent Advances in Polyphenol Research series, is edited by Annalisa Romani, Vincenzo Lattanzio, and Stéphane Quideau. They have once again, like their predecessors, put together an impressive collection of cutting-edge chapters written by expert scientists, internationally respected in their respective field of polyphenol sciences. This Volume 4 highlights some of the latest information and opinion on the following major research topics about polyphenols: Biosynthesis and genetic manipulation Ecological role of polyphenols in plant defense Actions of polyphenols in human health protection Physical organic chemistry and organic synthesis Chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, biologists, ecologists, food scientists and nutritionists will all find this book an invaluable resource. Libraries in all universities and research institutions where these disciplines are studied and taught should have copies on their bookshelves.

Book Description
The quality of red juices is strongly determined by their content of anthocyanins since these are responsible for the nutritional value and organoleptic properties. The final anthocyanin concentration greatly depends on juice production and, more specifically, on the disintegration of the pectic substances in the cell walls during maceration which increases anthocyanin extractability. This work evaluates the potential of ultrasound treatment during enzymatic maceration to enhance pectin degradation. The application of this technique allows for gentle processing conditions regarding temperature and time compared to the conventional enzymatic treatment. Concurrently, the arising pool of soluble pectic oligosaccharides and polysaccharides can be increased which beneficially affects anthocyanin stability by complexation. The resulting interactions are multifaceted depending on the structural properties of both involved compounds. This thesis expands the knowledge of the molecular mechanisms of pectin degradation leading to soluble polymers that increase the stability of anthocyanins by complexation.

Book Description
Flavonoids are abundant secondary metabolites found in plants and fungi that have various roles in these organisms, including pigmentation, cell signalling, plant defence and inter-organism communication. Due to their abundance in nature, flavonoids are also important components of the human diet, and the last four decades have seen an intense study focused on the structure characterization of flavonoids and on their roles in mammal metabolism. This book reviews most of the well-established activities of flavonoids, and we also present more recent research studies on the area of flavonoids, including the chemical aspects of structure characterization of flavonoids, the biosynthesis of flavonoids in model plants as well as their role in abiotic stress situations and in agriculture, the role of flavonoids in metabolism and health and their importance in foods, from consumption to their use as bioactive components.
