Magnetic Resonance has become an established technique to improve the understanding of food systems. Capturing contributions from a whole range of applications in food and representing the latest technical innovations, this will be a contemporary book on the topic. Based on a conference which has established an international reputation as the forum for advances in applications of magnetic resonance to food, the coverage will be dedicated to multiscale definition of food, quantitative NMR (qNMR), foodomics, on-line non-invasive NMR (dedicated to Brian P. Hills), quality and safety and new developments in the area. It is aimed at academics and industrialists who are committed to the utilisation of MR tools to improve our understanding of food.
Nuclear magnetic resonance imaging is one of several new experimental tech niques which have rec{ ,tly been applied to food systems. NMR in general and nuclear magnetic resonance imaging are powerful probes of the microscopic and macroscopic changes occurring in foods during processing, storage and utilization. The training that food scientists and food engineers have received in the past has often omitted specific courses in physical chemistry that form the theoretical and practical foundation necessary to fully utilized magnetic resonance experimental techniques. The goal of Magnetic Resonance Imaging in Foods is to introduce food scien tists and food engineers to magnetic resonance imaging and provide a basis for further study. As such the book begins with two chapters of an introductory nature. The first chapter introduces magnetic resonance phenomena, NMR in general, and MRI in detail. Particular emphasis is given to the limitations and typical ranges available for studying particular phenomena, for example, the range of diffusivities that can be studied using commercial grade NMR equipment. Chapter 2 gives a brief introduction to the classical physical model of NMR first introduced by Felix Bloch in 1946 and aspects important to the interpretation of MRI data. This chapter is provided for the researchers and students interested in more details of the basic theory. Chapter 2 can be skipped by those individuals not requiring more information on the basic theory of NMR. The next several chapters of the book are on applications of MRI to food systems.

Foreign bodies are the biggest single source of customer complaints for many food manufacturers, retailers and enforcement authorities. Foreign bodies are any undesirable solid objects in food and range from items entirely unconnected with the food such as glass or metal fragments to those related to the food such as bones or fruit stalks. Detecting foreign bodies in food discusses ways of preventing and managing incidents involving foreign bodies and reviews the range of current methods available for the detection and control of foreign bodies, together with a number of new and developing technologies.Part one addresses management issues, with chapters on identifying potential sources of foreign bodies, good manufacturing practice (GMP), the role of the hazard analysis and critical control point (HACCP) system and how best to manage incidents involving foreign bodies. The book also includes a chapter on the laboratory identification of foreign bodies. Part two examines methods for the detection and removal of foreign bodies. There are chapters on existing methods, including metal detection, magnets, optical sorting, X-ray systems and physical separation methods. Other chapters consider research on potential new technologies, including surface penetrating radar, microwave reflectance, nuclear magnetic resonance, electrical impedance and ultrasound.Detecting foreign bodies in food is a standard reference for all those concerned with ensuring the safety of food. - Discusses ways of preventing and managing incidents involving foreign bodies - Reviews the range of technologies available for effective detection and control of foreign bodies

In order to ensure a clear understanding of the processing methodologies, the text is enriched with descriptions of how digital images are formed, acquired, processed and how to extract information from them. A special emphasis is given to the application of imaging techniques in food and agriculture research.
This book is the first book on nuclear magnetic resonance study of water in food and biological materials. The authors present the methodology, research, and development results of qualitative and quantitative analysis of water in foods and biological materials using NMR and MRI. This book provides the latest NMR and MRI techniques for those researchers who have an interest in relationships between water and: * chemical reactivity * microbial activity * physiochemical properties and changes * structural properties and changes in foods and biological materials In addition, the authors emphasize experimental techniques and data interpretation skills for the study of mobility of water and its role in processing and storage of foods and biological materials. Authors Ruan and Chen explain how the "state of water" concept will greatly add to the reader's understanding of the role of water in chemical, physical and microbial changes occurring in foods and biological materials. Understanding the relationships between water and chemical reactivity, microbial activity, and physiochemical and structural properties and changes in foods is an important key to effective food R&D, as well as quality control in processing and storage. This book provides advanced information on these relationships using the tools of NMR and MRI. Emphasis is placed on experimental techniques and data interpretation skills for the study of mobility of water and its role in processing and storage of foods. Many new techniques and applications are examined. More than 140 schematics, images and graphs illustrate NMR/MRI principles, techniques, applications and results.
