Beads made from Egyptian faience have been excavated from grave deposits (c. 4000-3100 BC), together with beads of glazed steatite (a soft rock) and of se- precious stones such as turquoise, carnelian, quartz, and lapis lazuli. Information on these and many more ancient beads used for ornaments and jewelry, ritual ceremonies, as art artifacts and gifts for amorous women throughout history, and descriptions of the raw materials (e. g. , glass, bone, precious and other stones) and manufacturing technologies used for their production can be located in many references. Many books are devoted to the description of beads that are not of water-soluble polymer origin, techniques for their production, their art, value, and distribution, re?ecting the wealth of information existing in this ?eld of science and art. On the other hand, there are no books fully devoted to the fascinating topic of hydrocolloid (polymeric) beads and their unique applications. A few books c- tain scattered chapters and details on such topics, while emphasizing the possibility of locating fragments of information elsewhere; however, again, there is no book that is solely devoted to hydrocolloid beads and their versatile applications. In the meantime, the use of water-soluble hydrocolloid beads is on the rise in many ?elds, making a book that covers both past and novel applications of such beads, as well as their properties and ways in which to manipulate them, crucial.

It is a source of great satisfaction to us that a Second Edition of this treatise should be called for, especially because it has given us the opportunity to produce, we believe, a better book. Eighteen chapters, amounting to one-third of the whole, are new, and of these, 13 deal with subjects not covered at all in the First Edition. We have paid more attention to embryonic and fetal growth, with chapters on cell differentiation (Lehtonen and Saxen), embryonic growth (O'Rahilly and Muller), control of fetal size (Snow), regulation of fetal growth (D'Ercole and Underwood), and ultrasonic studies offetal growth (Meire). At last the data are available for a chapter on the evolution of the human growth curve, by Eliz- abeth Watts. Large parts of the endocrine section have been rewritten (by Michael Preece, and by William Crowley and Margaret Wierman), and the genetics section has been largely recast, with new contributions by William Mueller and Ronald Wilson. Reynaldo Marto- rell has contributed a new chapter on growth in developing countries, and Tanner discusses growth surveys and standards as well as catch-up growth. Finally, there are two new chap- ters dealing with growth as a monitor of the health of populations-one by Tadeusz Bie- licki, considering the contemporary scene, and the other by Robert Fogel, on the contri- bution that such studies are making to the economic history of the eighteenth and nineteenth centuries.

This comprehensive study of poultry meat safety offers readers the most up-to-date information on food safety concerns in poultry meat production. Chapters address recent topics of interest such as organic poultry production, antimicrobial resistant pathogens in poultry, antibiotic usage in poultry production, and pre- and post- harvest approaches to improving poultry meat safety. The last couple of decades have observed a significant increase in poultry meat production in the US. However, poultry meat is a potential source of foodborne pathogens such as Salmonella, Campylobacter spp. and pathogenic Escherichia coli (APEC linked to human infections), leading to economic losses to the poultry industry and impacting public health. Advances in knowledge in microbiology, molecular biology, immunology and "omics" fields have intensified efforts to improve the microbiological safety of poultry by targeting virulence mechanisms of the pathogens, developing vaccines and improving gut health in chickens. Moreover, due to the emergence of multidrug resistance in poultry-borne pathogens, and growth of organic poultry production, there exists significant interest for developing natural strategies for controlling pathogens in chickens. This edited volume provides insight into these strategies and covers other material of interest to food microbiologists, public health personnel, and poultry scientists. Readers of various backgrounds will appreciate its incorporation of recent developments not covered in other publications on the subject.

New and exciting biological functions are still being discovered for vitamin A derivatives, including the vast number of physiological activities of retinoids. In Retinoids: Methods and Protocols, expert researchers in the field present the most recent technical tools with diverse techniques for both in vitro and in vivo studies. Combining biochemical, biophysical, and cell biological techniques, the book addresses topics such as the detection and quantitation of retinoids using HPLC, mass spectrometry, and fluorescence, fluorescence anisotropy of retinol binding protein, cell culture models for studying retinoid transport and the role of retinol in embryonic stem cell culture, as well as many other detailed procedures. Written in the highly successful Methods in Molecular Biology(TM) series format, chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes highlighting tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Retinoids: Methods and Protocols seeks to aid beginning and experienced researchers from widely varied fields in the search to uncover even more vital aspects of vitamin A's impact on the human body.

Lipid peroxidation is an important cellular process which can lead to detrimental effects if it is not regulated efficiently. Lipid hydroperoxide is formed in an initial step of lipid peroxidation. Lipid hydroperoxide is also known as a potential source of singlet oxygen. Harmful aldehydes are formed when the lipid hydroperoxide is degraded. The formed aldehyde has high reactivity against thiol or amine moieties. Therefore, it could act as a signaling molecule, which might induce the changing of gears inside a cell. Recent studies have shown that lipid hydroperoxide or a slightly modified product of the lipid hydroperoxide reacts with biomolecules such as proteins and aminophospholipids, which leads to formation of amide-type adducts. Amide-type adducts could be one of markers for oxidative stress and could also be an important player in some diseases. In this book, the chemistry and biochemistry of lipid hydroperoxide along with their conjugates with biomolecules are described.

This book describes in detail those new and emerging food preservation techniques that are now, or soon will be, commerically exploited. The editor, a leading figure in this field, has assembled a team of well-known and respected contributors, who cover chemical, biological and physically based-approaches. Emphasis is placed both on the innovative exploitation of traditional procedures, including combination preservation methods, and on more radical approaches, such as the use of high hydrostatic pressures or voltage pulses to inactivate microorganisms in food, and the direct and synergistic application of ultrasonic radiation.

There is little doubt that today's food industry is faced with a rapidly changing market landscape. The obvious need to continue to provide consumers with nutritious, delectable, safe, and affordable food products which are also profitable for food manufacturers, as well as the ongoing challenge of ensuring the delivery of adequate nutrition to hundreds of millions of disadvantaged people around the world, appears - at least as much as, if not more than, ever - to be at odds with the challenges posed by soaring energy and food commodity prices; fast-paced changes in consumer demographics, habits, and preferences; and the continual need to stay ahead of current and emerging food safety issues. In addition to this, the present ubiquity in the industry of terms such as functional foods, nutraceuticals, low sodium, low fat, clean label, minimal processing, and natural - to name a few - underscores yet a different dimension of the challenges faced by food processors today. On the other hand, however, the solutions of many of these challenges may, concurrently, present the food industry with unique and exciting opportunities. The processed meat industry, despite its long history and tradition, is certainly not exempt from having to face these modern challenges, nor excluded from realizing the promises of the opportunities that may lie ahead.

Forecasts point out an exponential growth in the global population, which raises concerns over the ability of the current agri-food production systems to meet food demand in the long term. Such a prospect has led international organizations and the scientific community to raise awareness about, and call for, the need to identify additional sources of food to feed the world. From this perspective, insects qualify as a suitable and more environmentally friendly alternative to meat and other foods that are sourced from animal proteins. However, uptake of the production and commercialization of insects as food has been facing regulatory hurdles, consumer skepticism and rejection in many markets. This is particularly true in the context of western societies in which insects do not always constitute part of the local traditional diets.Production and Commercialization of Insects as Food and Feed: identification of the Main Constraints in the European Union analyses and discusses the regulatory state-of-the-art for the production and commercialization of insects as food and feed in the European Union. The EU has been taking concrete legislative steps with a view to opening up its market for insect foods, although some key regulatory constraints still exist today which ultimately prevent the industry sector from growing, consolidating and thriving. The main regulatory constraints in the EU for insects as food include the fragmentation of the EU market as a result of the adoption of different policy solutions by EU Member States for novel foods and the lengthy and complex authorization procedures. Also, ad hoc safety and quality requirements tailored to the needs and specificities of the insect food sector are currently missing. This work constitutes the first comprehensive overview of the evolution and current state-of-the-art of the regulatory framework for insect foods in the EU, based on a multidisciplinary approach that combines science, policy and law. It proposes a legislative roadmap which the EU should follow in order to make its regulatory framework fit for insect foods in the long term by providing a detailed comparison between the current EU legal framework and other regulatory systems of western countries with a view to singling out the markets which are better equipped to address the production and the commercialization of insect foods. The text provides an updated overview of the overall market and of European consumers' perspectives on the use of insect foods. With the proper legislative steps and consolidation, the EU can be a global leader for insects as food and feed both as a market and as a standard-setting body.

This book considers the rapid microbiological techniques that are now increasingly used in industry as alternatives to more conventional methods. Although many of the pioneering studies in this field have taken place in clinical laboratories, the materials listed and organisms sought for foods, beverages and pharmaceuticals are much more varied. In this volume, leading experts from research and industry review the wide variety of approaches that are needed in an industrial setting. The methods described include electrometric techniques, ATP assay, and immunological methods for a wide range of organisms from salmonellas to viruses, each chapter drawing on the authors direct experience in industry to give a highly practical guide. The book should prove invaluable to those in the food, beverage and pharmaceutical industries, or in research and training, who require an up-to-date survey of the use of rapid microbiological methods.

The increased emphasis on food safety during the past two decades has decreased the emphasis on the loss of food through spoilage, particularly in developed co- tries where food is more abundant. In these countries spoilage is a commercial issue that affects the pro't or loss of producers and manufacturers. In lesser developed countries spoilage continues to be a major concern. The amount of food lost to spoilage is not known. As will be evident in this text, stability and the type of spoilage are in?uenced by the inherent properties of the food and many other factors. During the Second World War a major effort was given to developing the te- nologies needed to ship foods to different regions of the world without spoilage. The food was essential to the military and to populations in countries that could not provide for themselves. Since then, progress has been made in improved product formulations, processing, packaging, and distribution systems. New products have continued to evolve, but for many new perishable foods product stability continues to be a limiting factor. Many new products have failed to reach the marketplace because of spoilage issues.

This is a basic reference/textbook for professionals and students involved with these important oils and fats. It is a valuable source of information for those preparing for or already professionally as sociated with the Food Processing and Foodservice industries. Chapters one through six deal with the technology of oils and fats, including sources, chemical structure, physical and chemical properties, and processing techniques. Chapters seven through twelve are devoted to the utilization of oils and fats in Food Manufacturing and Foodservice, including deep frying, griddling, baking of all types, salad dressings, margarines, hard butters, and dairy product re placements. The last four chapters contain a most complete and up to-date treatment of nutrition, as well as the latest developments in analytical methods, flavor, and product development as they relate to oils and fats. This book contains the necessary information for an understand ing of how oils and fats are used in the food industry and how this information is used to set standards and meet performance goals. In a thoroughly readable way it is a how-to-do, hands-on treatise on using oils and fats for every major food use. ix Acknowledgments I gratefully acknowledge many friends at Procter & Gamble who provided updated material, some currently employed and some re cently retired. Fred J. Baur, formerly of Procter & Gamble, wrote the updated chapters related to Analytical Methods, Flavor, Nutri tion, and Dietary Considerations."

The subject of sterilization of food in cans has been studied both experimentally and theoretically, but limited work has been undertaken to study the sterilization of food in pouches. This book examines the interaction between fluid mechanics, heat transfer and microbial inactivation during sterilization of food in pouches. Such interaction is complex and if ignored would lead to incorrect information not only on food sterility but also on food quality.

Rather than containing for the most part fairly detailed food science and technology intended for daily use and reference by food scientists and technologists, this book is designed for use by a much wider range of readers concerned with a particular and rapidly expanding area of food production, promotion, marketing, and packaging. A certain amount of basic detail is provided to enable relatively rough estimates of the production methods and packaging facilities necessary to enable new or improved items to be made, but the overall emphasis is on the wide range of food products that can now quite legitimately be regarded as coming within the broad definition of foods used as snacks, as contrasted with main meals. Thus, we start with the basic requirements to be met in a snack food whatever its nature, and follow with the great variety of items nowadays used 3..'l snacks or as adjuvants to snacks, concluding with an assessment of nutritional consequences of the growth of "snacking" or "browsing," and with the special packaging requirements of snack foods.

Safety of Meat and Processed Meat provides the reader with the recent developments in the safety of meat and processed meat, from the abattoir along the processing chain to the final product. To achieve this goal, the editor uses five approaches. The first part deals with the main biological contaminants like pathogen microorganisms, specially E. coli and L. monocytogenes, toxins and biogenic amines that can be present either in meat or its derived products. The second part focuses on main technologies for meat decontamination as well as developments like active packaging or bioprotective cultures to extend the shelf life. The third part presents non-biological contaminants and residues in meat and meat products including nitrosamines, PAH, veterinary drugs and environmental compounds. The fourth part discusses current methodologies for the detection of microorganisms, its toxins, veterinary drugs, environmental contaminants and GMOs, and the final part deals with predictive models, risk assessment, regulations on meat safety, consumer perception, and other recent trends in the field. This book is written by distinguished international contributors with excellent experience and reputation. In addition, brings together advances in different safety approaches.

Advances in the flavonoid field have been nothing short of spectacular over the last 20 years. While the medical field has noticed flavonoids for their potential antioxidant, anticancer and cardioprotectant characteristics, growers and processors in plant sciences have utilized flavonoid biosynthesis and the genetic manipulation of the flavonoid pathway in plants to improve the nutritional and ornamental value of crops. Flavonoids: Chemistry, Biochemistry and Applications covers each class of flavonoid and presents the historic advances made in flavonoid research since the 1994 publication of an earlier text, Flavonoids Advances in Research Since 1986. This book details the analytical techniques scientists have used to achieve an improved understanding of flavonoid structures and functions as well as advances in the genetic manipulation of the flavonoid pathway, and the discovery of many new flavonoids. It indicates which techniques are best suited for the isolation and structure determination of flavonoids and whether the structures are novel. While explaining how to evaluate the flavonoid content in food and beverages, the book reveals the biotechnological advances that have allowed nutritionists and plant physiologists to assess the possible effects of flavonoids. As interest regarding the impact and health benefits of flavonoids continues to grow, Flavonoids: Chemistry, Biochemistry and Applications reflects the continuing commitment of flavonoid researchers to the improvement of human health and provides the most comprehensive, up-to-date source of information for all known flavonoids.

The promotion of a high level of food safety and quality is of major importance world-wide. Aspects of food quality such as genetically modified organisms (GMOs), food allergens and food authentication have become increasingly important while food-borne diseases caused by bacteria, viruses and parasites continue to be a significant problem. The application of real-time PCR is one of the most promising advances in food safety and quality providing rapid, reliable and quantitative results. In recent years real-time PCR has become a valuable alternative to traditional detection methods in the agricultural and food industries. The advantages of quantitative real-time PCR include speed, an excellent detection limit, selectivity, specificity, sensitivity and the potential for automation.

Food processing is now the biggest industry in the UK and in many other countries. It is also rapidly changing from what was essentially a craft industry, batch processing relatively small amounts of product, to a very highly automated one with continuously operating high speed production lines. In addition, consumers have developed a greater expectation for consistently high standard products and coupled this with demands for such things as a more natural flavour, lower fat etc. The need for an increased knowledge of the scientific principles behind food processing has never been greater. Within the industry itself, increased automation, company diversification and amalgamations etc. have meant that those working in it have often to change their field of operation. Whereas twenty years ago, someone starting work in one branch of the food industry could expect, if he or she so desired, to work there all their working lives, this is now seldom the case. This means that a basic knowledge of the principles behind food processing is necessary both for the student at university or college, and for those already in the industry. It is hoped, therefore, that this book will appeal to both, and prove to be a useful reference over a wide range of food processing.

Traditionally, in the food industry, there has been a distinction made among meat, poultry, seafood, and game. Meat has historically been defined as the edible flesh of animals. This basically referred only to the red meats, namely, beef, lamb, pork, and veal, including both fresh and processed products as well as variety or glandular meats. It has been recognized more recently that all foods derived from muscle, or muscle foods, have basically the same or similar characteristics in physical and chemical properties. Tberefore, it is logical to exarnine and consider all muscle foods under one cover. Tbis book, therefore, is an attempt to address the various attributes of red meat, poultry, fish, and game under the single heading of muscle foods and to note any differences where they might OCCUT. It is of interest that of the 10 top V. S. meat companies in 1990, 8 of them were dealing with poultry as well as red meats and that 4 of the 10 were also involved with seafoods. Tbis lends impetus to the inclusion of all three in a book such as this. Furthermore, the rapid increase in consumption of poultry meat to approximately 30 kg (65 pounds) per capita and seafoods to 7 kg (16 pounds) per capita compared to beef at 34 kg (75 pounds) and pork at 30 kg (65 pounds), whereas veal and lamb/mutton represent only 0.

The machinery about which I am writing is found in the confectionery industry, but it is also generally used throughout the food industry and some other areas that produce items that need to be wrapped and packed for distribution. It just happens that much of my working life was spent in the confectionery industry. Similar machinery operates in the pharmaceutical industry, is used for wrapping and handling books, for wrapping blocks of fuel and for packing tea and other items. Some of the robots described are used in the glass industry, loading drinking glasses direct from hot moulding plants. They are used to load filled bottles into cases in the drinks business or shampoo for chemical manufacturers. Other industries, for example the textile industry, used machinery designed for other purposes (such as weaving), before the development of packaging machines, that worked on comparable principles. Some of the mechanisms in all of this machinery possibly have their ancestry in the great cathedral clock mechanisms from as early as the fifteenth century. Just because this book is mainly illustrated by reference to chocolate bars and sweets does not mean that that is the only application, nor does it lessen the ingenuity applied in the designs of these machines or their importance in the modem world.

In the food industry, controlling crystallization is a key factor in quality as it relates to texture, with some foods requiring the promotion of crystallization and others its prevention. In the first publication to focus specifically on this process as it applies to food, Crystallization in Foods covers fundamental principles in ice, sugar, and lipid crystallization, and their applications. Drawing on examples throughout of the practical use and impact of crystallization on food structure, texture, and quality; and enhanced with numerous equations and illustrations, Crystallization in Foods is a valuable resource for food engineers and other scientists working with crystallization in foods, particularly in the dairy, confectionery, frozen foods, and baked goods industries. In addition, this book may be of interest to scientists and other professionals in the personal care and cosmetics industry, which shares some of the same quality and texture concerns as the food industry.
