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 :

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 :

The book is a comprehensive treatment of the subject covering a wide range of subjects uniquely available in a single source for the first time. A material science approach has been adopted in dealing with wood adhesion and adhesives. The approach of the authors was to bring out hierarchical cellular and porous characteristics of wood with polymeric cell wall structure, along with the associated non-cell wall extractives, which greatly influence the interaction of wood substrate with polymeric adhesives in a very unique manner not existent in the case of other adherends. Environmental aspects, in particular formaldehyde emission from adhesive bonded wood products, has been included. A significant feature of the book is the inclusion of polymeric matrix materials for wood polymer composites.

Book Description :

Cellulose is a versatile and renewable natural resource which has attracted increasing attention in the last decade, expecially after the energy crisis of 1973. Apart from its extensive use as asolid product, wood is the most important source of cellulose fibres for papermaking and is also widely used as a source of energy. The form and availability ot· the forest provides a great opportunity for technological improvement and innovation in the future to satisfy the foreseeable increasing demand for wood based products. For example, North American sawmills and plywood mills presently recover only about 45 to 55% of logged wood while the remainder is disposed as waste, if it is not used in pulp manufacturing. In addition, top and branch wood, and logs from non-commercial species which are presently not recovered from the logging sites could provide an abundant and relatively inexpensive resource for the manufacture of composite products. Other valuable potential sour ces of cellulosic materials are waste paper and agricultural waste. A composite is the consolidation of two polymerie materials such that one of the components acts as the adhesive binder while the other forms the substrate matrix. In some cases, the matrix and the adhesive may be the same materials. To maximize the adhesion potential of the composite, the properties of the substrate which can enhance, hinder or complicate the development of optimum adhesion should be thoroughly explored and identified.

Book Description :

This book includes papers on polymeric materials from renewable resources known as `Biorelated Polymers and Plastics', and issues are bound to their utilization and environmental impact in their production, conversions to manufacts and ultimate disposal of post-costume manufacts. Modern industrial developments inspired by the new concepts of sustainability and ecocompatibility require a deeper attention to renewable resources as a new-old source of raw material and feedback. This new trend, occurring not only in industrialized countries but also in emerging countries and countries in transition, thoroughly permeates the polymer and plastic industry, due to the big impact that those materials have on the modern way of life. Plastic waste, specifically that stemming from segments of packaging, containers for solids and liquids and single use items, is attracting much effort from municipality officers, producers and converters, aimed at finding a harmonized solution among the various options available for their appropriate management. In this respect, polymeric materials of natural origin (biopolymers), as well as materials from renewable resources useable for the production of monomeric precursors, or semi-synthetic polymeric materials, constitute a focal point for future industrial development in the production of polymers and plastics. The present book contains much valuable information and scientific hints on a modern approach aimed at designing processes and products with minimal negative environmental impact.

Book Description :

Wood Extractives and their Significance to the Pulp and Paper Industries focuses on the promotion of the study of the biochemistry of wood extractives and to elaborate on the effects these materials may pose to the manufacture of pulp and paper. The publication first elaborates on wood, distribution and formation of polyphenols within the tree, and the simple polyphenolic constituents of plants. Discussions focus on the factors affecting the amounts of polyphenols present in living tissues, glycosidic combination, flavonols, anthocyanins, and leucoanthocyanins, formation of carbohydrates in the tree, types of polyphenols in different tissues of uninjured trees, and variation in structure and properties of wood. The text then examines lignans and condensed and hydrolyzable tannins. The manuscript takes a look at the alicyclic acid precursors of polyphenols, biosynthesis of polyphenols, and tropolones. Topics include tropolones occurring in wood, polymeric polyphenols, synthesis of pre-aromatic compounds, shikimic acid, and quinic acid. The book then ponders on the influence of extractives on the pulping of wood and the influence of extractives on the color of ground wood and newsprint. The publication is a valuable reference for researchers interested in the processes and methodologies involved in the manufacture of pulp and paper.

Book Description :

Plant polyphenols are specialized metabolites that constitute one of the most common and widespread groups of natural products. They are essential plant components for adaptation to the environment and possess a large and diverse range of biological functions that provide many benefits to both plants and humans. Polyphenols, from their structurally simplest forms to their oligo/polymeric versions (i.e. tannins and lignins), are phytoestrogens, plant pigments, antioxidants, and structural components of the plant cell wall. The interactions between tannins and proteins are involved in plant defense against predation, cause astringency in foods and beverages, and affect the nutritional and health properties of human and animal food plants. This eighth volume of the highly regarded Recent Advances in Polyphenol Research series is edited by Juha-Pekka Salminen, Kristiina Wähälä, Victor de Freitas, and Stéphane Quideau, and brings together chapters written by some of the leading experts working in the polyphenol sciences today. Topics covered include: Structure, reactivity and synthesis Bioactivity and bioavailability Metabolomics, targeted analysis and big data Quality control & standardization Biogenesis and functions in plants and ecosystems Biomaterials & applied sciences Distilling the most recent and illuminating data available, this new volume is an invaluable resource for chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, biologists, ecologists, food scientists and nutritionists.

Book Description :

This book was developed from the proceedings of the first North American Tannin Conference held in Port. Angeles, Washington, August 1988. The objective of the conference was to bring together people with a common interest in condensed tannins and to promote interdisciplinary interactions that will lead to a better understanding of these important substances. Anot. her objective was the publicat. ion of this book because there has not been a monograph devoted to the chemistry and significance of tannins for several decades. The book is organized into sections dealing with the biosynthesis, structure, re actions, complexation with other biopolymers, biological significance, and use of tannins as specialty chemicals. The authors made a special attempt to focus on what we don't know as well as to provide a summary of what we do know in an effort to assist in planning future research. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We also thank Rylee Geboski and the Conference Assist. ance Staff, College of Forestry, Oregon State University, for their assistance in planning and conducting t. he conference, and Julia Wilson, Debbie Wolfe, Helen Coletka, and Nancy Greene of the Southern Forest Experiment Station, Pineville, Louisiana, who typed the chapt. ers.
