Phytochemists are aware that their focus of interest is receiving attention from a wider segment of society and from a greater diversity of disciplines within the scientific community than ever before. Nonetheless, they were bemused to learn three years ago that "until recently scientists didn't even know phytochemi cals existed" (Newsweek, April 24, 1994). Changing public perception of the positive contributions of phytochemicals to human well-being has foundations in scientific advances. With popular reports emphasizing the important implica tions of phytochemicals in the daily lives of people, there is a pressing need for those working in this area to explain their diverse scientific activities to the public. Chemicals from plant foods are linked through epidemiological and ex perimental studies with reduced incidence of chronic degenerative diseases. Phytomedicines, standardized according to particular constituents, are making increasing contributions to health care. Naturally occurring constituents of plants are recognized as fundamental to the appeal, quality, and marketability of food products. In light of such developments, perceptions by phytochemists of their own discipline and its applications are expanding. Until recently, food phyto chemistry largely implied food toxicants. Food plants were familiar, but seldom the source of novel economically important compounds. Increasingly sophisti cated methods of analysis, however, have opened new opportunities for under standing the nature and functions offood constituents, and for manipulating them to improve the quality, acceptability, and value of food products.

Phytochemicals are plant derived chemicals which may bestow health benefits when consumed, whether medicinally or as part of a balanced diet. Given that plant foods are a major component of most diets worldwide, it is unsurprising that these foods represent the greatest source of phytochemicals for most people. Yet it is only relatively recently that due recognition has been given to the importance of phytochemicals in maintaining our health. New evidence for the role of specific plant food phytochemicals in protecting against the onset of diseases such as cancers and heart disease is continually being put forward. The increasing awareness of consumers of the link between diet and health has exponentially increased the number of scientific studies into the biological effects of these substances. The Handbook of Plant Food Phytochemicals provides a comprehensive overview of the occurrence, significance and factors effecting phytochemicals in plant foods. A key of objective of the book is to critically evaluate these aspects. Evaluation of the evidence for and against the quantifiable health benefits being imparted as expressed in terms of the reduction in the risk of disease conferred through the consumption of foods that are rich in phytochemicals. With world-leading editors and contributors, the Handbook of Plant Food Phytochemicals is an invaluable, cutting-edge resource for food scientists, nutritionists and plant biochemists. It covers the processing techniques aimed at the production of phytochemical-rich foods which can have a role in disease-prevention, making it ideal for both the food industry and those who are researching the health benefits of particular foods. Lecturers and advanced students will find it a helpful and readable guide to a constantly expanding subject area.

The book is devoted to expanding current views on the phenomena of protein functionality in food systems. Protein functionalities in foods have been the object ofextensive research over the last thirty to forty years and significant progress has been made in understanding the mechanism and factors influencing the functionality of proteins. The functionality of proteins is one of the fastest developing fields in the studies of protein utilization in foods. Currently, a broad spectrum of data related to protein functionality in food systems has been collected, however, much more needs to be known. In this volume, the most important functional properties offood proteins are presented: Protein solubility, water holding capacity and fat binding, emulsifying, foaming, and gelling properties as affected by protein source, environmental factors (pH, temperature, ionic strength) and protein concentration; Relationships between protein conformation, physicochemical properties, and functional properties; Protein functional properties as influenced by various food processing conditions, particularly heat treatment, dehydration, freezing and storage when frozen, extraction and other processes; Effects ofprotein modification on the enhancementofprotein functionality; Utilization ofvarious proteins in improving functional properties in food systems. Those aspects of protein functionality are presented which the author believes to be interesting and most important for protein utilization in food systems. The book is recommended to students and food scientists engaged in food protein research and food industry research, and development scientists.

From beef to baked goods, fish to flour, antioxidants are added to preserve the shelf life of foods and ensure consumer acceptability. These production-added components may also contribute to the overall availability of essential nutrients for intake as well as the prevention of the development of unwelcome product characteristics such as off-flavours or colours. However, there are processes that reduce the amount of naturally occurring antioxidants and awareness of that potential is just as important for those in product research and development. There is a practical need to understand not only the physiological importance of antioxidants in terms of consumer health benefit, but how they may be damaged or enhanced through the processing and packaging phases. This book presents information key to understanding how antioxidants change during production of a wide variety of food products, with a focus toward how this understanding may be translated effectively to other foods as well. Addresses how the composition of food is altered, the analytical techniques used, and the applications to other foods Presents in-chapter summary points and other translational insights into concepts, techniques, findings and approaches to processing of other foods Explores advances in analytical and methodological science within each chapter

Antioxidants are an increasingly important ingredient in food processing. Their traditional role is, as their name suggests, in inhibiting the development of oxidative rancidity in fat-based foods, particularly meat and dairy products and fried foods. However, more recent research has suggested a new role in inhibiting cardiovascular disease and cancer. Antioxidants in Food: Practical Applications provides a review of the functional role of antioxidants and discusses how they can be effectively exploited by the food industry. The first part of the book looks at antioxidants and food stability with chapters on the development of oxidative rancidity in foods, methods for inhibiting oxidation, and ways of measuring antioxidant activity. Part 2 looks at antioxidants and health, including chapters on antioxidants and cardiovascular disease, their antitumour properties, and bioavailability. A major trend in the food industry, driven by consumer concerns, has been the shift from the use of synthetic to natural ingredients in food products. Part 3 looks at the range of natural antioxidants available to the food manufacturer. The final section of the book looks at how these natural antioxidants can be effectively exploited, covering such issues as regulation, preparation, antixoxidant processing functionality and their use in a range of food products from meat and dairy products, frying oils and fried products, to fruit and vegetables and cereal products.

"Accuse not Nature! She has done her part; Do Thou but Thine!" Milton, Paradise Lost 1667 The concept that nature imparted to foods a health-giving and curative function is not new. Herbal teas and remedies have been used for centuries and continue in use in many parts of the world today. In modern society, we have turned to drugs to treat, miti gate, or prevent diseases. However, since the discovery of nutrients and our increasing analytical capabilities at the molecular level, we are beginning to become more knowledgeable of the biochemical structure-function relationship of the myriad of chemicals that occur naturally in foods and their effect on the human body. The holistic approach to medicine and diet that began in the 1970s has now seen a renewal as we realize that certain foods, because of the presence of specific biochemicals, can have a positive impact on an individual's health, physical well-being, and mental state. In fact, because of the negative image of drugs, and the grey area of s- xi Foreword xii plements, the use of foods that are "functional" is becoming a growth area for the food industry. In Japan this concept has led to one of the largest growing markets, where they have defined "functional foods" as regular foods derived only from naturally occurring in gredients. The Japanese further require that the functional foods be consumed as part of the diet and not in supplement form (i. e.
