Book Description
Methods in Polyphenol Chemistry documents the proceedings of the Plant Phenolics Group Symposium held at the University of Oxford, on 2-4 April 1963. The symposium focused on the methods and techniques which made advances in the chemistry and biochemistry of phenolic compounds possible. The development of paper chromatographic and ultraviolet spectroscopic techniques was particularly important and largely responsible for the rapid growth in knowledge of polyphenols which has occurred during the last 10-15 years. In addition to these two methods other spectroscopic techniques were dealt with at the symposium. Particular mention should perhaps be made of nuclear magnetic resonance spectroscopy which is becoming increasingly important in polyphenol chemistry. Modern chromatographic methods such as thin layer and gas-liquid techniques will probably be used extensively in the future. These will enable the analyses of polyphenol mixtures to be carried out more rapidly and with greater resolution. Polyamide chromatography also has high powers of resolution, although this technique has not been widely used owing to difficulties in obtaining supplies of polyamide powder. This situation has now improved, however.

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.

Plant Polyphenols

Languages : en
Pages : 1027
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 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

Book Description
Phenolic compounds as a large class of metabolites found in plants have attracted attention since long time ago due to their properties and the hope that they will show beneficial health effects when taken as dietary supplements. This book presents the state of the art of some of the natural sources of phenolic compounds, for example, medicinal plants, grapes or blue maize, as well as the modern methods of extraction, quantification, and identification, and there is a special section discussing the treatment, removal, and degradation of phenols, an important issue in those phenols derived from the pharmaceutical or petrochemical industries.

Chemistry and Significance of Condensed Tannins

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. Linda Chalker-Scott was especially helpful in assisting us wit. h editing. Dick Hemingway is indebted t. o the staff of the Alexandria Forest.

Methods of Analysis of Food Components and Additives
Author: Semih Otles
Publisher: CRC Press
ISBN: 0203503759
Category : Technology & Engineering
Languages : en
Pages : 451
Book Description
With diet and health news making headlines on a regular basis, the ability to separate, identify, and analyze the nutrients, additives, and toxicological compounds found in food and food compounds is more important than ever. This requires proper training in the application of the best methods, as well as knowledgeable efforts to improve existing methods to meet certain analytical needs. Methods of Analysis for Food Components and Additives is a concise guide to both new and established methods for the analysis of food components and additives. The book presents detailed explanations of modern methods of analysis by 32 leading scientists, many of whom personally developed or refined the techniques. They summarize key findings on novel methods of analysis of food components, additives, and contaminants, including the identification, speciation, and determination of components in raw materials and food products. Each chapter is structured to provide a description of the component or additive that can be analyzed, a simple method explanation of how it works, examples of applications, and references for more specific information. This comprehensive volume features all major classes of food components and contaminants, along with components of current interest to the nutraceutical and functional foods industries. It is an essential reference for food scientists and chemists, as well as food manufacturers and researchers interested in the many methods of food analysis.
