Book Description
From the Introduction With regard to nitrate and nitrite, the perceived hazards are to the ecological balance in rivers and lakes, and to human health. Increased nitrate levels in river water lead to increased growth of algae and consequent decrease in the level of biologically available oxygen (BAO). In extreme forms, the algae form unsightly blooms on the water surface, and the BAO level falls below that necessary to support fish and other animal life. At this extreme, there is little dispute that efforts should be made to restore the ecological balance, and this is best achieved by reversing the increase in nitrate concentration that caused the problem. The health hazards are less clear, but include the risk of methaemoglobinaemia in young infants and the possible risk of gastric cancer, particularly in certain high-risk patient groups. These health risks have led to legislation to control the exposure of humans to nitrate from drinking water and as a food additive . . . What can be done about this and how can the problem be solved (if, indeed, there is a problem)? It is normal practice to add nitrate and nitrite to food as a cosmetic and as a preservative. Is this necessary? If so, how much do we need to add? Are there alternatives? What effect does added nitrate have on total nitrate exposure of humans? . . . In this book, we have attempted to answer, or at least to give the background to, some of the questions. . . .

Book Description
Nitrite and Nitrate in Human Health and Disease delivers a comprehensive review of nitrite and nitrate biology, from basic biochemistry to the complex physiology and metabolism of these two naturally occurring molecules in the human body. Well-organized and well referenced chapters cover the rich history of nitrite and nitrate, sources of exposure, and the physiological effects when consumed through foods containing nitrite and nitrate. The chapters are written by leading experts, all of whom share their research and perspectives in order to help define the context for benefits vs. any potential risks associated with nitrite and nitrate use, either through dietary ingestion or therapeutic dosing. This diverse collection of authors includes vascular biologists, physiologists, physicians, epidemiologists, cancer biologists, registered dieticians, chemists, and public health experts from five countries in both academia and government. Nitrite and Nitrate in Human Health and Disease provides a balanced view of nitric oxide biochemistry, and nitrite and nitrate biochemistry in physiology and in the food sciences.

Book Description
An internationally respected editorial team and array of chapter contributors has developed the Handbook of Fermented Meat and Poultry, an updated and comprehensive hands-on reference book on the science and technology of processing fermented meat and poultry products. Beginning with the principles of processing fermented meat and ending with discussions of product quality, safety, and consumer acceptance, the book takes three approaches: background and principles; product categories; and product quality and safety. The historical background on the fermentation of meat and poultry products is followed by a series of discussions on their science and technology: curing, fermentation, drying and smoking, basic ingredients (raw product, additives, spices, and casings), and starter cultures. Coverage of product categories details the science and technology of making various fermented meat and poultry products from different parts of the world, including: semidry-fermented sausages (summer sausage), dry-fermented sausages (salami), sausages from other meats, and ripened meat products (ham). Product quality and safety is probably the most important aspect of making fermented meat and poultry because it addresses the question of consumer acceptance and public health safety. While a processor may produce a wonderful sausage, the product must ultimately satisfy the consumer in terms of color, texture, taste, flavor, packaging, and so on. In the current political and social climate, food safety has a high priority. Coverage includes issues such as spoilage microorganisms, pathogens, amines, toxins, HACCP and disease outbreaks.

Book Description
Flavour is an important sensory aspect of the overall acceptability of meat products. Whether we accept or reject a food depends primarily on its flavour. Both desirable and undesirable flavour effects are contemplated. Furthermore, threshold values of different flavour-active compounds have an important effect on the cumulative sensory properties of all foods. Meat from different species constitutes a major source of protein for most people. Although raw meat has little flavour and only a blood-like taste, it is a rich reservoir of non-volatile compounds with taste-tactile properties as well as flavour enhancers and aroma precursors. Non-vola tile water-soluble precursors and lipids influence the flavour of meat from different species. In addition, mode of heat processing and the nature of additives used may have a profound effect on the flavour of prepared meats. This book reports the latest advancements in meat flavour research. Following a brief overview, chapters 2 to 5 discuss flavours from different species of meat, namely beef, pork, poultry and mutton. In chapters 6 to 12 the role of meat constituents and processing on flavour are described. The final section of the book (chapters 13 to 15) summarizes analytical methodologies for assessing the flavour quality of meats. I wish to thank all the authors for their cooperative efforts and com mendable contributions which have made this publication possible.

Book Description
Inherent toxicants and processing contaminants are bothnon-essential, bioactive substances whose levels in foods can bedifficult to control. This volume covers both types of compound forthe first time, examining their beneficial as well as theirundesirable effects in the human diet. Chapters have been writtenas individually comprehensive reviews, and topics have beenselected to illustrate recent scientific advances in understandingof the occurrence and mechanism of formation, exposure/riskassessment and developments in the underpinning analyticalmethodology. A wide range of contaminants are examined in detail,including pyrrolizidine alkaloids, glucosinolates, phycotoxins, andmycotoxins. Several process contaminants (eg acrylamide and furan),which are relatively new but which have a rapidly growingliterature, are also covered. The book provides a practical reference for a wide range ofexperts: specialist toxicologists (chemists and food chemists),hygienists, government officials and anyone who needs to be awareof the main issues concerning toxicants and process contaminants infood. It will also be a valuable introduction to the subject forpost-graduate students.

Book Description
Handbook of Molecular Gastronomy: Scientific Foundations and Culinary Applications presents a unique overview of molecular gastronomy, the scientific discipline dedicated to the study of phenomena that occur during the preparation and consumption of dishes. It deals with the chemistry, biology and physics of food preparation, along with the physiology of food consumption. As such, it represents the first attempt at a comprehensive reference in molecular gastronomy, along with a practical guide, through selected examples, to molecular cuisine and the more recent applications named note by note cuisine. While several books already exist for a general audience, either addressing food science in general in a "light" way and/or dealing with modern cooking techniques and recipes, no book exists so far that encompasses the whole molecular gastronomy field, providing a strong interdisciplinary background in the physics, biology and chemistry of food and food preparation, along with good discussions on creativity and the art of cooking. Features: Gives A–Z coverage to the underlying science (physics, chemistry and biology) and technology, as well as all the key cooking issues (ingredients, tools and methods). Encompasses the science and practice of molecular gastronomy in the most accessible and up-to-date reference available. Contains a final section with unique recipes by famous chefs. The book is organized in three parts. The first and main part is about the scientific discipline of molecular and physical gastronomy; it is organized as an encyclopedia, with entries in alphabetical order, gathering the contributions of more than 100 authors, all leading scientists in food sciences, providing a broad overview of the most recent research in molecular gastronomy. The second part addresses educational applications of molecular gastronomy, from primary schools to universities. The third part provides some innovative recipes by chefs from various parts of the world. The authors have made a particular pedagogical effort in proposing several educational levels, from elementary introduction to deep scientific formalism, in order to satisfy the broadest possible audience (scientists and non-scientists). This new resource should be very useful to food scientists and chefs, as well as food and culinary science students and all lay people interested in gastronomy.
