Nutritional and Toxicological Consequences of Food Processing


Book Description

A variety of processing methods are used to make foods edible; to pennit storage; to alter texture and flavor; to sterilize and pasteurize food; and to destroy microorganisms and other toxins. These methods include baking, broiling, cooking, freezing, frying, and roasting. Many such efforts have both beneficial and harmful effects. It is a paradox of nature that the processing of foods can improve nutrition, quality, safety, and taste, and yet occasionally lead to the formation of anti-nutritional and toxic compounds. These multifaceted consequences of food processing arise from molecular interactions among nutrients with each other and with other food ingredients. Since beneficial and adverse effects of food processing are of increasing importance to food science, nutrition, and human health, and since many of the compounds formed have been shown to be potent carcinogens and growth inhibitors in animals, I organized a symposium broadly concerned with the nutritional and toxicological consequences of food processing. The symposium was sponsored by the American Institute of Nutrition (AIN) -Federation of American Societies for Experimental Biology (FASEB) for its annual meeting in Washington, D.C., April 1-5, 1990. Invited speakers were asked to develop at least one of the following topics: 1. Nutrient-nonnutrient interactions between amino acids, proteins, carbohydrates, lipids, minerals, vitamins, tannins, fiber, natural toxicants, etc. 2. Effects of radiation. 3. Thermally induced formation of dietary mutagens, antimutagens, carcinogens, anticarcinogens, antioxidants, and growth inhibitors. 4. Effects of pH on nutritional value and safety.




Food Irradiation


Book Description

Bestrahlung von Lebensmitteln - dieser Band beschreibt Wirkungen, Anwendungsgebiete und Grenzen. International renommierte Fachleute konzentrieren sich in ihren Beiträgen auf wissenschaftliche und technologische Details, weniger auf die Streitfrage, ob Lebensmittel überhaupt bestrahlt werden sollten. Die Diskussion ist eingebettet in die Bestimmungen des Kontrollsystems HACCP, das in der fleisch- und fischverarbeitenden Industrie der USA und Europas mittlerweile Pflicht ist.




Food Irradiation


Book Description

Food Irradiation focuses on the fundamental aspects and applications of food irradiation. It summarizes efforts to establish the wholesomeness of irradiated foods, and it discusses the nature of ionizing radiation, as well as its interaction with matter, the biological effects it induces in living organisms associated with food such as raw fruits and vegetables, and the application of these effects in treating foods. The book also highlights some aspects of food irradiation that have potential significance in commercial usage, including consumer attitudes, costs, facilities, and safety. Organized into 15 chapters, this volume begins with an overview of ionizing radiation and its biological effects, the basics of radiation chemistry, and radiation chemistry of foods and food components. It then discusses the general effects of ionizing radiation on foods; irradiation of foods, such as meats and poultry, marine and freshwater animal foods, beverages, and dairy products; government regulation of irradiated foods; and consumer acceptance of irradiated foods. This book is a valuable source of information for food technologists, nutritionists, and suppliers of irradiation facilities and equipment.




Irradiation of Food and Packaging


Book Description

This book presents extensive coverage of irradiated foods and food products contaminated with food borne pathogens, and the effects on irradiation and packaging materials and additives. It also shows the effects ionizing radiation has on improved functional components in fresh fruits and vegetables.




Food Irradiation Technologies


Book Description

Food preservation by irradiation is gaining recognition as a technology that is more environmentally benign than other current processes such as post-harvest chemical fumigation, it has less impact on thermally sensitive compounds than thermal decontamination technologies such as hot water or steam, and the technology is more accessible and cheaper. As the technical and economic feasibility, as well as the level of consumer acceptance, have increased its use has been growing fast. International organizations including the Food and Agriculture Organization of the United Nations (FAO), the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) have coordinated and worked with others to develop norms and review the safety and efficacy of irradiated foods. Commended in the Foreword by Carl Blackburn, Food Irradiation Specialist, Joint FAO / IAEA Division of Nuclear Techniques in Food and Agriculture, this book makes a strong case for the use of this overwhelmingly safe food processing technique. This comprehensive book is a useful reference for food technologists, analytical chemists and food processing professionals, covering all aspects of gamma, electron beam and X-ray food irradiation, its impact on food matrices and microorganisms, legislation and market aspects. It is the first book to cover control and structural analysis in food irradiation and, being written by leading experts in the field, addresses the current global best practices. It contains updated information about the commercial application of food irradiation technology, especially regarding the type of radiation based on food classes and covers dosimetry, radiation chemistry, food decontamination, food quarantine, food processing and food sterilization.

Food Irradiation Research and Technology


Book Description

The benefits of food irradiation to the public health have been described extensively by organizations such as the Centers for Disease Control and Prevention in the U.S. and the World Health Organization. The American Medical Association and the American Dietetic Association have both endorsed the irradiation process. Yet the potential health benefits of irradiation are unknown to many consumers and food industry representatives who are wary of irradiated foods due to myth-information from “consumer-advocate” groups. Food Irradiation Research and Technology presents the latest scientific findings of researchers at the leading edge of food irradiation. In this book, experts from industry, government, and academia: define the basic principles of irradiation and the public health benefits of irradiation describe advances in irradiation technology, detection technology, and radiation dosimetry review the regulations pertaining to food irradiation and the toxicological safety data provide food industry representatives and public health officials with effective methodologies to educate consumers and counteract misinformation review recent advances in the irradiation of meat and poultry, fruits and vegetables, seafood, and the use of irradiation as a phytosanitary treatment Food Irradiation Research and Technology appeals to a broad readership: industry food scientists involved in the processing of meat and fish, fruits and vegetables; food microbiologists and radiation processing specialists; government and industry representatives involved in the import and export of food commodities; and industry, local, and state officials involved in educational efforts regarding food irradiation. Food scientists and technologists share a responsibility to ensure that educational materials provided to the public regarding food safety and processing technologies are based on sound science and fact, not on misconceptions. Food Irradiation Research and Technology meets that goal.




Electromagnetic Radiations in Food Science


Book Description

This book has been written for those whose interests bridge food processing and physicochemical aspects of radiation. It is not intended to be a comprehensive review of publications concerning foods and radiations. Instead, it is an attempt to familiarize the reader with pertinent knowledge of a unified, interdisciplinary concept of various electromagnetic radiations and corresponding effects on foods. Consideration was given to similarities and differ ences between various segments of the electromagnetic spectrum. The broad approach of this book was considered to be crucial for cross-discipline comparisons. The reader is introduced to the electromagnetic spectrum in the Prologue and then the book follows the wavelengths, from short to long values. Chapter 1 deals with ionizing radiation: historical background, sources of radiation employed in food treatment, units of measurement, and fundamentals of radiation chemistry. A survey of potential applications of ionizing radiation in food technology is followed by a description of methods for radiation dosimetry. Safety and wholesomeness of irradiated foods, analytical methods for postirradiation dosimetry in foods, and consumer acceptance of food irradiation conclude this section. Chapter 2 intrudes into the next segment of the spectrum: ultra violet-visible radiation. The general presentation of this electro magnetic emission and illumination source enables the discussion of its effects on foods, including applications in food analysis.
