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.

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.
"Food Contaminants and Residue Analysis" treats different aspects
of the analysis of contaminants and residues in food and highlights
some current concerns facing this field. The content is initiated
by an overview on food safety, the objectives and importance of
determining contaminants and residues in food, and the problems and
challenges associated to these analyses. This is followed by full
details of relevant EU and USA regulations. Topics, such as
conventional chromatographic methods, accommodating cleanup, and
preparing substances for further instrumental analysis, are
encompassed with new analytical techniques that have been
developed, significantly, over the past few years, like solid phase
microextraction, liquid chromatography-mass spectrometry,
immunoassays, and biosensors. A wide range of toxic contaminants
and residues, from pesticides to mycotoxins or dioxins are
examined, including polychlorinated biphenyls, polycyclic aromatic
hydrocarbons, N-nitrosamines, heterocyclic amines, acrylamide,
semicarbazide, phthalates and food packing migrating substances.
This book can be a practical resource that offers ideas on how to
choose the most effective techniques for determining these
compounds as well as on how to solve problems or to provide
relevant information.
Fortified foods and food supplements remain popular with today s

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.
Consumer acceptance is the key to successful food products. It is
vital, therefore, that product development strategies are
consumer-led for food products to be well received. Consumer-led
food product development presents an up-to-date review of the
latest scientific research and methods in this important area.
This book seeks to unravel the mysteries of wolfberry, and systematically introduces its mechanisms in preventing aging-associated diseases, such as cardiovascular diseases, inflammation, liver and neurodegenerative diseases. Wolfberry, the dried fruit of Lycium barbarum, is an anti-aging herbal medicine. There have been numerous reports investigating the underlying mechanisms of its anti-aging effects and its role in preventing pathological changes in many aging-associated diseases. Its holistic effects on the body can attenuate liver toxicity and combat the spread of cancer; it also prevents degeneration in the central nervous system, and can even positively affect the skin. As such, wolfberry has become a very popular food supplement around the world. This book will serve as an excellent reference source for researchers and graduate students studying herbal medicine and aging-associated diseases, while also providing insights for the pharmaceutical industry with regard to developing potential drugs for these diseases.

yoghurt of consistently high quality. The book has been completely
revised and updated to produce this third edition, which combines
coverage of recent developments in scientific understanding with
information about established methods of best practice to achieve a
comprehensive treatment of the subject. General acceptance of a
more liberal definition by the dairy industry of the term yoghurt
has also warranted coverage in the new edition of a larger variety
of gelled or viscous fermented milk products, containing a wider
range of cultures.
This book is designed to integrate the basic concepts of food safety with current developments and challenges in food safety and authentication. The first part describes basics of food safety, classification of food toxins, regulation and risk assessment. The second part focuses on particular toxins like mycotoxins, aromatic amines, heavy metals, pesticides, and polycyclic hydrocarbons. Recent developments and improvements in the detection of these contaminants are described. The third part deals with the authenticity and adulteration of food and food products, a topic which affects food trade on a national and international level.
Food and beverages can be very aggressive chemical milieu and may
interact strongly with materials that they touch. Whenever food is
placed in contact with another substance, there is a risk that
chemicals from the contact material may migrate into the food.
These chemicals may be harmful if ingested in large quantities, or
impart a taint or odour to the food, negatively affecting food
quality. Food packaging is the most obvious example of a food
contact material. As the demand for pre-packaged foods increases,
so might the potential risk to consumers from the release of
chemicals into the food product. Chemical migration and food
contact materials reviews the latest controls and research in this
field and how they can be used to ensure that food is safe to eat.

Agrifood biotechnology - the genetic transformation of plants and animals through recombinant means - has created controversy in the food system for more than twenty years. This thoroughly revised and amended edition of Paul B. Thompson's path breaking study of ethical and philosophical issues raised by this technology up to date.The original 1997 edition was the first book length treatment by a philosopher to focus on food and agricultural biotechnology, covering ethical issues associated with risk assessment, labelling, animal transformation, patents, & the impact of biotechnology on traditional farming communities in both the developed & developing world. The new edition reflects lessons from the hotly contested debates over those issues in the intervening decade, and includes wholly new discussions on ethical issues associated with livestock cloning, the Precautionary Principle, and the transatlantic debate between United States and European perspectives on biotechnology.
An indispensable reference, this book provides an overview of the main mycotoxins in food. It is the first complete reference dedicated to toxin producing fungi in foodstuff. The book lists the degree of contamination, concentration of the toxins, and the country of origin and/or detection for each case of contamination presented in the book. Moreover, the book discusses whether a foodstuff is predisposed for mycotoxin contamination. It is written for professionals in the food industry, agriculture, control agencies, food processing, food chemistry, microbiology, and mycology.
"Microorganisms in Foods 8: Use of Data for Assessing Process Control and Product Acceptance" is written by the International Commission on Microbiological Specifications for Foods with assistance from a limited number of consultants. The purpose of this book is to provide guidance on appropriate testing of food processing environments, processing lines, and finished product to enhance the safety and microbiological quality of the food supply. Microorganisms in Foods 8 consists of two parts. Part I, Principles of Using Data in Microbial Control, builds on the principles of "Microorganisms in Foods 7: Microbiological Testing in Food Safety Management" (2002), which illustrates how HACCP and Good Hygienic Practices (GHP) provide greater assurance of safety than microbiological testing, but also identifies circumstances where microbiological testing may play a useful role. Part II, Specific Applications to Commodities, provides practical examples of criteria and other tests and is an updated and expanded version of Part II of "Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications" (2nd ed. 1986). Part II also builds on the 2nd edition of "Microorganisms in Foods 6: Microbial Ecology of Food Commodities" (2005) by identifying appropriate tests to evaluation the effectiveness of controls.
