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 in Plants: Isolation, Purification and Extract Preparation, 2nd edition, provides a detailed insight into polyphenols that occur naturally in plants and how they can be affected during growth and development, then effectively removed and optimized for various applications in food production. Historically, plants have been the major sources for drugs and health promotion. While there are a small number of nutrients contained, the growing focus is on the very diverse, complex ring structures: polyphenols that are not nutritious. In order to study or use them in patient treatment, the polyphenols need to be isolated, identified, and purified for application and study. This book brings together experts in the field who share their ongoing examination of isolation and purification of polyphenols as well as determination of their structures and composition. Polyphenols in Plants covers a range of new topics including polyphenols in vegetable waste and agricultural byproducts, extraction methods and characterization of polyphenols, and isolation techniques in the development of new compounds and their use in cancer therapy. This book will be useful to plant scientists and dietary supplement producers, as well as scientists in the food industry and alternative medicine who are interested in the specific health benefits of various dietary extracts and other polyphenol resources. Fully revised and updated to present the latest developments in the field Advances understanding of isolation, characterization, and identification of critical polyphenols vital to industrial development as therapies Defines conditions of growth affecting polyphenol levels Describes techniques critical to identifying and defining polyphenols

Book Description
Polyphenolic compounds are part of a division of secondary metabolites with high antioxidant capacity, found naturally in most edible and inedible plants. These compounds are responsible for pigmentation and plants defense of pathogens agents. Its molecular structure includes phenolic hydroxyl groups and aromatic rings. Polyphenols are increasingly studied because of the benefits to human health, introducing the ability to eliminate free radicals generated by oxidation, reducing risk of cancer, anti-aging, anti-diabetic, among others. This book provides new research on food sources of polyphenolic compounds, and their biochemistry and health benefits.

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
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.
