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.

Sind Zeichen und Medien in der Lage, Wirkungen auszulösen, die sich mit denjenigen von Drogen und Arzneimitteln vergleichen lassen? Die Studie erschließt die Potenzen ›heilender Zeichen‹ und ›toxischer Texte‹ sowie die Bedeutungswirkungen von Placebo-Effekten. Im Gegensatz zu breit erforschten Effekten wie Gänsehaut oder Herzrasen wurden genuin pharmakologische körperliche Wirkungen in den Medien- und Kulturwissenschaften bislang allenfalls marginal beschrieben. Die Studie erschließt die umfangreiche Phänomenologie der erheblichen biophysiologischen Beeinflussung des Körpers durch semantisch-mediale Inputs, die im günstigen Fall organische Krankheiten heilen, aber auch schädliche Effekte verursachen können, bis hin zu ›Tod durch Zeichen‹. Dabei dienen die Bedeutungswirkungen von Placebo-Effekten als Paradigma der kultur- und medienwissenschaftlichen Untersuchung. Sie liefert damit aus einer neuen Perspektive auch eine umfangreiche Validierung der verschiedenen ›Körperdiskurse‹ bzw. ›Krankheitskulturen‹ aus den siebziger und achtziger Jahren.

This text provides both review and primary research articles for a broad audience of biologists, chemists, biochemists, pharmacologists, clinicians and nutrition experts, especially those interested in the biosynthesis, structure, function and/or bioactivity of plant natural products. Recurring themes include the evolution and ecology of specialized metabolites, the genetic and enzymatic mechanisms for their formation and metabolism, the systems biology study of their cell/tissue/organ context, the engineering of plant natural products, as well as various aspects of their application for human health. In addition to analysis of current research, new developments in the techniques used to study plant natural products are presented and discussed, taking a detailed look at structure elucidation and quantification, “omic” (genomic/ proteomic/ transcriptomic/ metabolomics) profiling or for microscopic localization. In short, this series combines chapters from researchers that explain and discuss current topics in the most exciting new research in phytochemistry.

The emergence of new infectious, chronic and drug resistant diseases have prompted scientists to look towards medicinal plants as agents for treatment and prevention. This book provides an interphase between ethnomedical and ethnobotanical approaches to new drug discovery and advances in biotechnology and molecular science that has made it increasingly feasible to transform traditional medicines into modern drugs. These novel approaches also raise new issues and the volume explores economic, ethical and policy considerations of drug development based on indigenous knowledge or traditional medicine. This work also features standardization and development of phytomedicines for major therapeutic indications, including emerging infectious diseases affecting developing and developed countries. The publication provides state-of-the-art information on the most innovative science, the research, the industry, the market, and the future of ethnomedicine and drug discovery.

Plant foods are rich in micronutrients, but they also contain an immense variety of biologically-active, non-nutritive compounds that contribute to colour, flavour and other characteristics. This book assesses the health benefits of phytochemicals, as well as the functional benefits of particular groups of phytochemicals such as phytoestogens, carotenoids and flavonoids. It covers key safety and quality issues in developing phytochemical products, instituting appropriate intake levels, testing for safety and establishing health claims through clinical trials. This book will establish itself as a standard reference on one of the most important sectors in the functional foods market.

Functional foods and bioactives of microbial, plant and animal origin, including probiotics, herbs, spices, vegetables, specialty fruits, seafood and milk components. Impact on the microbiome, emerging metabolic pathways and prevention of chronic and infectious diseases.Techniques for functional food development and evaluation.Regulatory and safety considerations. This volume presents basic and advanced technical information on the sources, mechanisms and safety of food bioactives in the etiology and prevention of chronic and infectious diseases. In this context, it offers details useful not only for understanding but also improving the functionality of foods. It reviews advances in multiple phytochemicals and food ingredients known for positive effects on human physiology, including interactions with the human microbiome. Metabolomic and proteomic techniques are explored as ways of improving the understanding of mechanisms of action, and increasing the therapeutic effectiveness of selected food ingredients. Special attention is given to chemistry, molecular structure and pharmacological effects of bioactive ingredients. Bioactives from a wide range of foods are investigated, including pro- and prebiotics, fungi, yeasts, herbs, spices, fruits, vegetables, seafood and many more. The text provides systematic information needed to develop and validate commercial products incorporating functional ingredients.

Consumers around the world have become better educated and more demanding in their identification and purchase of quality health-promoting foods; therefore the food industry requires innovative technologies to provide their clientele with safe and stable foods that meet safety regulations . Improving Food Quality with Novel Food Processing Technologies details novel processing technologies including high pressure processing (HPP) and pulsed electrical fields (PEFs) that can improve the quality of food from functionality, chemistry/microbiology, bioactive quantity, and shelf-life standpoints. The authors discuss how to improve food functionality with high hydrostatic pressure (HHP) and PEFs. They focus on improving the quality and retaining bioactive constituents of fruits and vegetables and improving the quality of dairy, egg, meat, and seafood products with HHP. Broad in scope, the book also reviews the modeling and simulations of HHP inactivation of microorganisms and the relative effects of HHP processing on food allergies and intolerances. It then discusses improving food functionality with PEF processes in dairy and egg products, fruit juices, and wine. A chapter attending to industrial applications of HHP and PEF systems and potential commercial quality and shelf life of food products concludes this discussion. During the past decade, novel processing technologies including HHP, ultrasound, PEF, and advanced heating technologies containing microwave, ohmic heating, and radio frequency have frequently been applied in the processing of foods and beverages. Successful research and identification of economic benefits, including energy and water conservation as well as demonstrated safety and fresh-like quality attributes will improve consumer perception of nonthermal technologies and result in further development by the food industry around the world. In an in-depth exploration of these novel technologies, the book gives you the skills for product development and improvement.
