This concisely written book presents information on types of plant phenolics. The sole focus of this volume is on dietary tannins. It reviews the fact that tannins interact with dietary proteins, carbohydrates, minerals, vitamins, digestive enzymes, and lower nutrient availability. This work reveals that in certain parts of the world, tannins also have been reported as carcinogenic. This literature comprehensively reviews chemistry and plant biochemistry, and methods of extraction. It also explains the harmful and toxic effects and remedies to alleviate dietary tannins. This useful resource is a must for all food scientists, nutritionists, biochemists, and animal scientists throughout the world.

From health and economic consequences to exposure assessment and detoxification, this reference comprehensively covers the formation, characteristics, and control of various toxins that occur in the production, storage, handling, and preparation of food. The author discusses toxin sources, mechanisms, routes of exposure and absorption, and their chemical and biochemical components to prevent contamination of food products and reduce epidemics of foodborne disease. The book contains more than 3000 references to facilitate further research, as well as recent guidelines from the FDA and World Health Organization regarding food hygiene and safety.

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.

Sustainable Swine Nutrition As climate change continues to have a significant impact on the modern world, it is crucial to find alternative sources of energy and nutrients for swine production. The development of optimal feeding revolves around a multitude of considerations—genetic variations in the pig, variability, availability, and stability of nutrients in feed ingredients, interactions among nutrients and non-nutritive factors, voluntary feed intake, physical (& social) environment of pigs, and more. Establishing the ideal network of factors will only grow in importance as humans assess the methods for our own food networks. Sustainable Swine Nutrition is a comprehensive book on swine nutrition, covering some fundamental aspects of nutrition—namely digestive physiology, water, protein or amino acids, lipids, carbohydrates, energy metabolism, vitamins, minerals, and nutrition and immunology. Providing the most up-to-date information on each of these areas, a major emphasis of this second edition is on recent developments and current advances in the field, with a focus on pertinent issues linked with energy and nutrients. In doing so, the book highlights topics and issues that can contribute to the ultimate goal of successful and sustainable swine production. Sustainable Swine Nutrition readers will also find: Environmentally friendly, optimal feeding strategies for successful and sustainable swine production Recent developments, such as alternative feedstuffs, feed additives, and bioavailability Expanded treatment and new chapters on swine physiology, energy and protein, technology, and more Sustainable Swine Nutrition, Second Edition, is an ideal resource for livestock scientists and industry professionals involved in all aspects of pork production.

Humans have utilized the bioactive principles of different plants for various beneficial physiological properties including antimicrobial properties for many centuries. However, interests of using medicinal plants declined in the 20th century with the availability of effective synthetic antimicrobial drugs. The development of microbial resistance to various drugs has accelerated research interests towards the use of phytochemicals as alternatives to synthetic drugs in the recent years. This book presents an comprehensive reviews on the antimicrobial and antiviral properties of numerous recently reported phytochemicals, and their mechanisms of antimicrobial actions. Some of the chapters have critically discussed the beneficial and adverse effects of antibacterial, and stimulatory activities of dietary phytochemicals on rumen microbial populations, and gut microbial populations of humans and animals. Microbial adaptation and resistance of microbes to phytochemicals has also been highlighted. On the applied apects, the use of phytochemicals against drug resistance microbes, to treat microbial diseases, for food preservation, to inhibit methanogenic archaea in the rumen, and to modulate lipid biohydrogenating microbial populations to increase conjugated linoleic acids in animal-derived foods have been presented in different chapters.

It has been more than ten years since the first edition of this book was published. During this time, our understanding of the interactions between plants and the animals that consume them, as mediated by secondary compounds (allelochemicals) of plants, has grown dramatically.In the Herbivores: Their Interactions with Secondary Plant Metabolites, Second Edition, only those areas of research where significant progress has been made since 1979 are included, and most of the contributing authors are new. This edition has been split into two volumes due to the vast amount of new material that has been generated on this subject.Both volumes will be of interest to evolutionary biologists, agriculturists, chemists, biochemists, physiologists, and ecologists.Volume 1, provides an exhaustive update and review of the chemical and biochemical bases for the role and function of allelochemicals in their defense against herbivores.Volume 2, scheduled for publication in April 1992, provides a current update of the research on the ecological roles and evolutionary nature of secondary plant metabolites in their interactions among plants and as protective agents against environmental stresses such as consumption by herbivores.

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.
