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.
In this book, some of the most qualified scientists review different food safety topics, ranging from emerging and reemerging foodborne pathogens, food regulations in the USA, food risk analysis and the most important foodborne pathogens based on food commodities. This book provides the reader with the necessary knowledge to understand some of the complexities of food safety. However, anybody with basic knowledge in microbiology will find in this book additional information related to a variety of food safety topics.

(Chapter 13). The final part covers the use of chemicals in sustainable agriculture and food/energy security with Leonard Gianessi and Ashley Williams communicating the role of herbicides and Harold Reetz emphasizing the importance of fertilizers both in maximizing crop yields to maintain a sustainable secure source for food production."
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.
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.
Bambara groundnut (Vigna subterranea) is a crop native to the Bambara tribe of Mali and is grown as a subsistence crop in Africa. Recent advances in research, however, have brought the crop to the forefront of the sustainable agriculture movement. The Bambara plant is highly drought tolerant and rich in protein and carbohydrates, including starch. These macromolecules have enormous industrial potentials. For example, the starch in Bambara grain has been found to exhibit higher (double) viscosity than conventional corn starch. Modified Bambara groundnut starch has been used to produce edible bioplastics that could be upgraded industrially to suit the fourth industrial revolution shift. Bambara plants are also a natural source of soluble fiber, which is gluten-, lactose- and cholesterol-free, with potential as a stabiliser, thickener and gelling agent as well as a cryoprotectant in frozen products. The health benefits include lowering of cholesterol levels, levelling of blood glucose and as a detoxing aid. Furthermore, several researchers have explored the grain either alone or as composite with cereal and tubers for the development of value-added products. Food and Potential Industrial Applications of Bambara Groundnut presents in a clear, coherent way the research findings on Bambara grain and its status as a promising food and industrial crop.
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.

This book is focused on the challenges to implement sustainability in diverse contexts such as agribusiness, natural resource systems and new technologies. The experiences made by the researchers of the School of Agricultural, Forestry, Food and Environmental Science (SAFE) of the University of Basilicata offer a wide and multidisciplinary approach to the identification and testing of different solutions tailored to the economic, social and environmental characteristics of the region and the surrounding areas. Basilicata's productive system is mainly based on activities related to the agricultural sector and exploitation of natural resources but it has seen, in recent years, an industrial development driven by the discovery of oil fields. SAFE research took up the challenge posed by market competition to create value through the sustainable use of renewable and non-renewable resources of the territory. Moreover, due to its unique geographical position in the middle of the Mediterranean basin, Basilicata is an excellent "open sky" laboratory for testing sustainable solutions adaptable to other Mediterranean areas. This collection of multidisciplinary case studies and research experiences from SAFE researchers and their scientific partners is a stimulating contribution to the debate on the development of sustainable techniques, methods and applications for the Mediterranean regions.
Food Physics deals with the physical properties of food, food ingredients and their measurement. Physical properties of food play a key role in all fields where modern technological processes are applied for the generation of food raw materials and the production of food. The determination of physical properties of food and related products are a pre-requisite for planning, production engineering and automation processes in today s food, pharmaceutical and cosmetics industries as well as in all related quality control activities. This book describes the principles of food physics starting with the very basics and focuses on the needs of practitioners without omitting important basic principles. It will be indispensable for future students of food technology and food chemistry as well as for engineers, technologists and technicians in the food industries. "
Familiar combinations of ingredients and processing make the structures that give food its properties. For example in ice cream, the emulsifiers and proteins stabilize partly crystalline milk fat as an emulsion, freezing (crystallization) of some of the water gives the product its hardness and polysaccharide stabilizers keep it smooth. Why different recipes work as they do is largely governed by the rules of physical chemistry. This textbook introduces the physical chemistry essential to understanding the behavior of foods. Starting with the simplest model of molecules attracting and repelling one another while being moved by the randomizing effect of heat, the laws of thermodynamics are used to derive important properties of foods such as flavor binding and water activity. Most foods contain multiple phases and the same molecular model is used to understand phase diagrams, phase separation and the properties of surfaces. The remaining chapters focus on the formation and properties of specific structures in foods - crystals, polymers, dispersions and gels. Only a basic understanding of food science is needed, and no mathematics or chemistry beyond the introductory college courses is required. At all stages, examples from the primary literature are used to illustrate the text and to highlight the practical applications of physical chemistry in food science.
"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.
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.
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. |
