Описание:
Polyphenols in Plants: Isolation, Purification and Extract Preparation provides insight into how the polyphenols that occur naturally in plants can be affected during growth and development, and then effectively removed and optimized, before being implemented in food production.
Historically plants have been the major sources for drugs and health promotion. There are a small number of nutrients. However, the growing focus is on the very diverse, complex ring structures, polyphenols that are not nutritious. To study or use them in patient treatment the polyphenols need to be isolated, identified, and purified for use and study. This book will bring together experts that will update their continuing study of ways to isolate and purify polyphenols as well as determine their structures and composition. In addition, some will update their previous summaries with new research by others as well as themselves.
Plant scientists and dietary supplement producers will be particularly interested in assessing polyphenol content and factors impacting their composition, to select sources and regulate environmental conditions affecting yield for more consistent and functional dietary supplements.
Fully revised and updated with 12 new chapters including extraction optimization, additional plant varieties and recent technology advances
Develops understanding of isolation, characterization and identification of critical polyphenols vital to industrial development as therapies
Defines conditions of growth affecting the polyphenol levels
Describes assay and instrumentation techniques critical to identifying and defining polyphenols, vital to researchers and business development
Provides insights into potential dangers and importance to the dietary supplement industry, government regulators and lay public users

Описание:
This book focuses on polyphenols in the Mediterranean diet, providing a detailed overview of their chemical structure, extraction and analysis methods, and their role in the diet and in flavor.
Phenols are important not only in terms of preventing a number of diseases due to their antimicrobial and antioxidant effects, but also in shaping our perception of foods. The first chapter discusses consumers' sensory assessment of foods containing polyphenols in terms of flavor and color, as well as the chemical properties and natural sources of phenolic compounds. The second chapter examines hygiene and safety claims with respect to naturally occurring polyphenols, especially in connection with organoleptic features. The third and final chapter examines the dietary sources of these molecules from various fruits, including processed products such as infusions, wines, oils and olives.
Given its scope, this book is a valuable resource for researchers in academia and industry interested in food safety, hygiene and production issues related to the Mediterranean diet.

Описание:
There is a wealth of published research on the health-promoting effects of green tea and its various components including polyphenols. Green Tea Polyphenols: Nutraceuticals of Modern Life presents a collection of global findings on the numerous health benefits of green tea polyphenols, confirming their position as healthy functional ingredients. With chapters contributed by experts in the field of green tea science and the inclusion of extensive references, this book provides an authoritative volume that can be used to guide researchers, scientists, and regulatory bodies.
Each chapter previews a specific theme and highlights recent research and development conducted in the field. The book begins with the history, processing, and features of green tea. It then describes the chemical composition and biochemical and physicochemical characteristics, followed by a discussion of the properties of green tea polyphenols, including metabolism, bioavailability, and safety. The subsequent chapters deal with the numerous health benefits associated with consumption of green tea polyphenols. These include benefits related to cancer risk and prevention, cardiovascular disease, protection of internal organs, diabetes and weight management, bone and muscle health, allergies, oral care, inflammation, and gut health.
The book addresses the nutrigenomics and proteomics of poyphenols. It also examines food and nonfood applications of green tea polyphenols, such as extracts, supplements, and skin and hair cosmetic products, demonstrating both therapeutic and functional health benefits. This book brings together a wide array of data on green tea polyphenols, providing a greater understanding of them and insight into their effects on human health, and their applications and commercial potential.

Описание: 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.

Описание: This book is first of its kind exclusively dedicated to plant polyphenol oxidases (PPOs), highlighting their importance in the food processing industry. By reviewing the scientific developments of the past several decades, it offers a comprehensive overview of various aspects of plant PPOs, including chemistry, structure, functions, regulation, genetics/genomics and molecular aspects. PPOs are copper-containing proteins found in several plant species that catalyze the hydroxylation of o-monophenols to o-diphenols and oxidation of the o-dihydroxyphenols to o-quinones. Further, the quonines undergo self-polymerization or react with amines/thiol groups to produce brown/dark coloration of products. All the PPOs contain two Cu-binding sites (CuA and CuB) as their central domain, these interact with phenolic substrates and molecular oxygen. Several of the plant PPOs contain an N-terminal transit peptide (~80-100 amino acids ) necessary for plastid import. The PPOs occur in latent form that are activated by various treatments including acid and base shock, exposure to detergents or proteolytic degradation. The pH optimum of PPOs varies widely depending upon different plant species but is usually ~4.0 – 8.0. Similarly, the optimum temperature also varies as per the source and substrate involved ranging from 30 to 45 °C. Multiple PPO isoforms have been reported in several plant species, and the chromosomal location of PPOs has also been studied in some species. The physiological role (s) of PPOs is not entirely understood, but they could be involved in defense-related functions in plants. From an applied perspective, PPOs are implicated in enzymatic browning/darkening of cereal products, vegetables and fruits. Interestingly, browning is preferred in some instances like the processing of black tea, cocoa, and coffee as it enhances their quality by forming flavorful products. There have b een initiatives to specifically breed and develop cultivars with reasonably low PPO levels in the mature grain or fruit. Further, several types of inhibitors that reduce the PPO activity have also been identified. Despite their commercial/economic importance and the availability of literature on different aspects of PPOs in different plant species, this is the first book to provide basic information regarding PPOs. It is a valuable resource for researchers involved in quality-related research specifically in crops, vegetables and fruits. Further, as PPOs are also implicated in defense- or stress-related functions, the book is also useful to breeders, pathologists, molecular biologists, physiologists and entomologists.
