Hydrocolloids are among the most widely used ingredients in the food industry. They function as thickening and gelling agents, texturizers, stabilisers and emulsifiers and in addition have application in areas such as edible coatings and flavour release. Products reformulated for fat reduction are particularly dependent on hydrocolloids for satisfactory sensory quality. They now also find increasing applications in the health area as dietary fibre of low calorific value.
The first edition of Handbook of Hydrocolloids provided professionals in the food industry with relevant practical information about the range of hydrocolloid ingredients readily and at the same time authoritatively. It was exceptionally well received and has subsequently been used as the substantive reference on these food ingredients. Extensively revised and expanded and containing eight new chapters, this major new edition strengthens that reputation.
Edited by two leading international authorities in the field, the second edition reviews over twenty-five hydrocolloids, covering structure and properties, processing, functionality, applications and regulatory status. Since there is now greater emphasis on the protein hydrocolloids, new chapters on vegetable proteins and egg protein have been added. Coverage of microbial polysaccharides has also been increased and the developing role of the exudate gums recognised, with a new chapter on Gum Ghatti. Protein-polysaccharide complexes are finding increased application in food products and a new chapter on this topic as been added. Two additional chapters reviewing the role of hydrocolloids in emulsification and their role as dietary fibre and subsequent health benefits are also included.
The second edition of Handbook of hydrocolloids is an essential reference for post-graduate students, research scientists and food manufacturers.

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.

This volume covers novel technologies, including high pressure, antimicrobials, and electromagnetism, and their impact.

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.

This book systematically covers immunoassays for food, presenting detailed approaches such as antigen design, food matrix pre-treatment and detection format optimization for 9 classes of food hazards and nutrition constituents.

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.

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.
Part one discusses the regulation and quality control of chemical migration into food. Part two reviews the latest developments in areas such as exposure estimation and analysis of food contact materials. The final part contains specific chapters on major food contact materials and packaging types, such as recycled plastics, metals, paper and board, multi-layer packaging and intelligent packaging.
With its distinguished editors and international team of authors, Chemical migration and food contact materials is an essential reference for scientists and professionals in food packaging manufacture and food processing, as well as all those concerned with assessing the safety of food.
