The rapidly expanding field of food safety includes many new
developments in the understanding of the entire range of toxic
compounds found in foods -- whether naturally occurring or having
been introduced by industry or food processing methods. This 2e of
"Introduction to Food Toxicology" explores these developments while
continuing to provide a core understanding of the basic principles
of food toxicology.
In recent years, professionals have combined nutrition, health, and engineering sciences to develop new technologies within the food industry. As we are beginning to shift focus on how we view the health benefits of various food products, perseveration and processing techniques have become much more vital.

"Functional food or medicinal food is any fresh or processed food claimed to have a health-promoting and/or disease-preventing property beyond the basic nutritional function of supplying nutrients, although there is no consensus on an exact definition of the term. This is an emerging field in food science, in which such foods are usually accompanied by health claims for marketing purposes, such as a company's 'cereal is a significant source of fiber. Studies have shown that an increased amount of fiber in one's diet can decrease the risk of certain types of cancer in individuals.' Functional foods are sometimes called nutraceuticals, a portmanteau of nutrition and pharmaceutical, and can include food that has been genetically modified. The general category includes processed food made from functional food ingredients, or fortified with health-promoting additives, like "vitamin-enriched" products, and also fresh foods (e.g., "vegetables") that have specific claims attached. Fermented foods with live cultures are often also considered to be functional foods with probiotic benefits."
Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the "scientific methods". Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, It will focus on the secondary metabolic compounds which afford protection against diseases. Lastly, Volume 3 focuses on the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.
Enrobed and filled confectionery and bakery products, such as
praline-style chocolates, confectionery bars and chocolate-coated
biscuits and ice-creams, are popular with consumers. The coating
and filling can negatively affect product quality and shelf-life,
but with the correct product design and manufacturing technology,
the characteristics of the end-product can be much improved. This
book provides a comprehensive overview of quality issues affecting
enrobed and filled products and strategies to enhance product
quality.
More than just coincidence connects a Tate & Lyle lawsuit and artificial sweetener to Jamaican-born Chemist Bert Fraser-Reid. From his first experience of Chemistry through his diabetic father, to his determination and drive as a Chemistry student in Canada, Fraser-Reid weaves a remarkable tale integrating science, law and autobiographical anecdotes. This book arises from the lawsuit brought by Tate & Lyle against companies accused of infringing its patents for sucralose, the sweet ingredient in the artificial sweetener SPLENDA which is made by chlorinating sugar. From a 1958 undergraduate intern witnessing the pioneering experiments on sugar chlorination, to being the 1991 recipient of the world's premiere prize for carbohydrate chemistry, Fraser-Reid was groomed for his role as expert witness in the mentioned lawsuit. Nevertheless, it seems more than his career links Fraser-Reid to the case.
This book primarily covers the general description of foodborne pathogens and their mechanisms of pathogenesis, control and prevention, and detection strategies, with easy-to-comprehend illustrations. The book is an essential resource for food microbiology graduate or undergraduate students, microbiology professionals, and academicians involved in food microbiology, food safety, and food defense-related research or teaching. This new edition covers the significant progress that has been made since 2008 in understanding the pathogenic mechanism of some common foodborne pathogens, and the host-pathogen interaction. Foodborne and food-associated zoonotic pathogens, responsible for high rates of mortality and morbidity, are discussed in detail. Chapters on foodborne viruses, parasites, molds and mycotoxins, and fish and shellfish are expanded. Additionally, chapters on opportunistic and emerging foodborne pathogens including Nipah virus, Ebola virus, Aeromonas hydrophila, Brucella abortus, Clostridium difficile, Cronobacter sakazakii, and Plesiomonas shigelloides have been added. The second edition contains more line drawings, color photographs, and hand-drawn illustrations.
This volume covers novel technologies, including high pressure, antimicrobials, and electromagnetism, and their impact.
Statistical Methods in Food and Consumer Research continues to be
the only book to focus solely on the statistical techniques used in
sensory testing of foods, pharmaceuticals, cosmetics, and other
consumer products.
Food flavour technology is of key importance for the food industry. Increasingly, food products must comply with legal requirements and conform to consumer demands for "natural" products, but the simple fact is that, if foods do not taste good, they will not be consumed and any nutritional benefit will be lost. There is therefore keen interest throughout the world in the production, utilisation and analysis of flavours. The second edition of this successful book offers a broad introduction to the formulation, origins, analysis and performance of food flavours, updating the original chapters and adding valuable new material that introduces some of the newer methodologies and recent advances. The creation of flavourings is the starting point for the book, outlining the methodology and constraints faced by flavourists. Further constraints are considered in a chapter dealing with international legislation. The origins of flavours are described in three chapters covering thermal generation, biogeneration and natural sources, keeping in mind the adjustments that manufacturers have had to make to their raw materials and processes to meet the demand for natural products whilst complying with cost issues. Delivery of flavours using encapsulation or through an understanding of the properties of the food matrix is described in the next two chapters, and this section is followed by chapters describing the different ways to analyse flavours using instrumental, modelling and sensory techniques. The book is aimed at food scientists and technologists, ingredients suppliers, quality assurance personnel, analytical chemists and biotechnologists.
This book describes a robust, low-cost electrochemical sensing system that is able to detect hormones and phthalates - the most ubiquitous endocrine disruptor compounds - in beverages and is sufficiently flexible to be readily coupled with any existing chemical or biochemical sensing system. A novel type of silicon substrate-based smart interdigital transducer, developed using MEMS semiconductor fabrication technology, is employed in conjunction with electrochemical impedance spectroscopy to allow real-time detection and analysis. Furthermore, the presented interdigital capacitive sensor design offers a sufficient penetration depth of the fringing electric field to permit bulk sample testing. The authors address all aspects of the development of the system and fully explain its benefits. The book will be of wide interest to engineers, scientists, and researchers working in the fields of physical electrochemistry and biochemistry at the undergraduate, postgraduate, and research levels. It will also be highly relevant for practitioners and researchers involved in the development of electromagnetic sensors.
Low water activity (aw) and dried foods such as dried dairy and meat products, grain-based and dried ready-to-eat cereal products, powdered infant formula, peanut and nut pastes, as well as flours and meals have increasingly been associated with product recalls and foodborne outbreaks due to contamination by pathogens such as Salmonella spp. and enterohemorrhagic E. coli. In particular, recent foodborne outbreaks and product recalls related to Salmonella-contaminated spices have raised the level of public health concern for spices as agents of foodborne illnesses. Presently, most spices are grown outside the U.S., mainly in 8 countries: India, Indonesia, China, Brazil, Peru, Madagascar, Mexico and Vietnam. Many of these countries are under-developed and spices are harvested and stored with little heed to sanitation. The FDA has regulatory oversight of spices in the United States; however, the agency's control is largely limited to enforcing regulatory compliance through sampling and testing only after imported foodstuffs have crossed the U.S. border. Unfortunately, statistical sampling plans are inefficient tools for ensuring total food safety. As a result, the development and use of decontamination treatments is key. This book provides an understanding of the microbial challenges to the safety of low aw foods, and a historic backdrop to the paradigm shift now highlighting low aw foods as vehicles for foodborne pathogens. Up-to-date facts and figures of foodborne illness outbreaks and product recalls are included. Special attention is given to the uncanny ability of Salmonella to persist under dry conditions in food processing plants and foods. A section is dedicated specifically to processing plant investigations, providing practical approaches to determining sources of persistent bacterial strains in the industrial food processing environment. Readers are guided through dry cleaning, wet cleaning and alternatives to processing plant hygiene and sanitation. Separate chapters are devoted to low aw food commodities of interest including spices, dried dairy-based products, low aw meat products, dried ready-to-eat cereal products, powdered infant formula, nuts and nut pastes, flours and meals, chocolate and confectionary, dried teas and herbs, and pet foods. The book provides regulatory testing guidelines and recommendations as well as guidance through methodological and sampling challenges to testing spices and low aw foods for the presence of foodborne pathogens. Chapters also address decontamination processes for low aw foods, including heat, steam, irradiation, microwave, and alternative energy-based treatments.
Fortified foods and food supplements remain popular with today s
health-conscious consumers and the range of bioactives added to
food is increasing. This collection provides a comprehensive
summary of the technology of food fortification and supplementation
and associated safety and regulatory aspects.
With the world s growing population, the provision of a safe,
nutritious and wholesome food supply for all has become a major
challenge. To achieve this, effective risk management based on
sound science and unbiased information is required by all
stakeholders, including the food industry, governments and
consumers themselves. In addition, the globalization of the food
supply requires the harmonization of policies and standards based
on a common understanding of food safety among authorities in
countries around the world. With some 280 chapters, the
Encyclopedia of Food Safety provides unbiased and concise overviews
which form in total a comprehensive coverage of a broad range of
food safety topics, which may be grouped under the following
general categories: History and basic sciences that support food
safety; Foodborne diseases, including surveillance and
investigation; Foodborne hazards, including microbiological and
chemical agents; Substances added to food, both directly and
indirectly; Food technologies, including the latest developments;
Food commodities, including their potential hazards and controls;
Food safety management systems, including their elements and the
roles of stakeholders. The Encyclopedia provides a platform for
experts from the field of food safety and related fields, such as
nutrition, food science and technology and environment to share and
learn from state-of-the art expertise with the rest of the food
safety community. Assembled with the objective of facilitating the work of those working in the field of food safety and related fields, such as nutrition, food science and technology and environment-this work covers the entire spectrum of food safety topics into one comprehensive reference work. The Editors have made every effort to ensure that this workmeets strict quality and pedagogical thresholds such as: contributions by the foremost authorities in their fields; unbiased and concise overviews on a multitude of food safety subjects; references for further information, and specialized and general definitions for food safety terminology. In maintaining confidence in the safety of the food supply, sound scientific information is key to effectively and efficiently assessing, managing and communicating on food safety risks. Yet, professionals and other specialists working in this multidisciplinary field are finding it increasingly difficult to keep up with developments outside their immediate areas of expertise. This single source of concise, reliable and authoritative information on food safety has, more than ever, become a necessity. "

It is intended for a broad range of areas, including biologists and food chemists, and is sure to become a key reference resource for students and professionals alike.
Grapevine is a crop of major economical interest, and wine represents a multicultural heritage which has been growing since several milleniums. Yet, modern viticulture must face several challenges. Global climate has increased berry sugar content (and alcohol in the wine) whereas phenolic and aromatic ripeness are not always achieved. Water supply is becoming shorter. New varieties better adapted to new climatic conditions might have to be planted, which may affect wine typicity. Phytochemical treatments are more controlled, and the consumer pays increasing attention to environmentally safe practices. New methods reducing pesticide use, but maintaining yield and typicity, must be designed. The present book illustrates the recent progress made in ecophysiology, molecular and cell biology, and pathology of grapevine, as well as in precision viticulture and berry composition. Combination of these new tools with field observations will undoubtly make it easier to face the challenges described above. These multidisciplinary contributions will be of interest to anyone involved in grapevine and wine activities.
One of the recent developments in regard to food safety is the legal change that consumers have a right to be sold safe food, and that the primary producer is now part of the process, which must guarantee the delivery of safe products.
