One of the challenges facing the world is feeding the ever-increasing population, with food security being a growing 21st century problem. This stresses the need for coordinated international systems to prevent and mitigate food fraud in global food supply chains. Food fraud, which is usually financially motivated, has significant consequences including unfair competition, major damage to markets and organizations, loss of consumer confidence, and it raises food safety issues.A shift toward a more plant-based diet can be endorsed to promote sustainability but also to improve public health and minimize animal suffering. The aim of this book is to deal with issues related to authenticity and chemometrics of the most important food products of plant origin, such as cereals, nuts, legumes, table olives and olive oil, coffee, tea, fruits and vegetables, fruit juices, spices, mushrooms, beers and wines, and honey, using state-of-the-art analytical techniques and instrumentation coupled with available chemometric tools.

Biosensors are poised to make a large impact in environmental, food, and biomedical applications, as they clearly offer advantages over standard analytical methods, including minimal sample preparation and handling, real-time detection, rapid detection of analytes, and the ability to be used by non-skilled personnel. Covering numerous applications of biosensors used in food and the environment, Portable Biosensing of Food Toxicants and Environmental Pollutants presents basic knowledge on biosensor technology at a postgraduate level and explores the latest advances in chemical sensor technology for researchers.By providing useful, state-of-the-art information on recent developments in biosensing devices, the book offers both newcomers and experts a roadmap to this technology. In the book, distinguished researchers from around the world show how portable and handheld nanosensors, such as dynamic DNA and protein arrays, enable rapid and accurate detection of environmental pollutants and pathogens.The book first introduces the basic principles of biosensing for newcomers to the technology. It then explains how the integration of a "receptor" can provide analytically useful information. It also describes trends in biosensing and examines how a small-sized device can have portability for the in situ determination of toxicants. The book concludes with several examples illustrating how to determine toxicants in food and environmental samples.
