The field of antioxidant research has grown rapidly over the last 30 years and shows no sign of slowing down. In order to understand how antioxidants work, it is essential to understand how their activity is measured. However, antioxidant activity measurements are controversial and their value has been challenged. This book addresses a number of the controversies on antioxidant testing methods. Specifically, the book highlights the importance of context, helping the reader to decide what methods are most appropriate for different situations, how the results can be interpreted and what information may be inferred from the data. There are a multiplicity of methods for measuring activity, with no standardized method approved for in vitro or in vivo testing. In order to select an appropriate method, a thorough knowledge of the processes associated with reduction-oxidation is essential, leading to an improved understanding and use of activity measurements and the associated data. The book presents background information, in a unique style, which is designed to assist readers to grasp the fundamentals of redox processes, as well as thermodynamics and kinetics, which are essential to later chapters. Recovery and extraction of antioxidants from diverse matrices are presented in a clear and logical fashion along with methods used to determine antioxidant activity from a mechanistic perspective. Other chapters present current methodologies used for activity testing in different sample types ranging from foods and plants, to body fluids and even to packaging, but always with a strong emphasis on the nature of the sample and the underlying chemistry of the method. A number of emerging techniques for assessing antioxidant behaviour, namely, electrochemical methods, chip technology exploiting microfluidic devices, metabolomics plus studies of gene and protein expression, are examined. Ultimately, these techniques will be involved in generation of'big data'for which an understanding of chemometrics will be essential in drawing valid conclusions. The book is written to appeal to a wide audience, but will be particularly helpful for any researchers who are attempting to make sense of the vast literature and often conflicting messages on antioxidant activity.

Traditionally, dietary fat has been associated with negative effects on human health by consumers due to its high energy density. However, today it is well known that the quality of the fat ingested is more important than its quantity, and that there are natural lipophilic compounds that are essential for the correct maintenance of human physiological functions. For this reason, the negative image associated with dietary fat consumption is not fully justified. Dietary fat is a hot research area that has attracted increasing attention in the last decades. An adequate intake of dietary fats adapted to our age and physical activity, as well as an increase in the intake of beneficial fatty compounds and controlling the intake of those types of fats that have negative effects on our health, can be powerful allies in preventing the development of chronic non-communicable diseases. Through this book, the Editors have compiled the most up to date and well-documented information on many aspects of the development and application of novel dietary patterns related to fatty compounds, with special emphasis on beneficial effects. They have considered fatty nutritional requirements at different stages of life, the international guidelines and the application of new -omics techniques, such as epigenetics, nutrigenomics, metabolomics and metagenomics, related to human health. This book will be of interest to researchers in food technology and biomedicine, as well as the food industry and food distribution areas.

Trace element analysis plays a prominent role in various fields, from mineralogy and geology to semiconductor manufacture and foods. In geochemical exploration, the analysis of trace elements assumes high significance due to the multifaceted role played by them. The analyte is at the detection limit of many instrumental techniques. This makes their determination difficult This book covers a wide spectrum of destructive and non-destructive analytical techniques and recent developments in them used all over the world, including developing countries, for quantitation of trace elements. With revolutionary progress in the last three to four decades in analytical techniques, several ICP-based techniques like ICP-OES and ICP-MS and other nuclear analytical techniques have enabled determination of trace elements at the ppb level. However, these methods require expensive instrumentation and cannot be made available everywhere. The quality of analytical data is dependent on valid reference standards. The book contains detailed sample preparation in varying matrices and an important chapter on statistical treatment of analytical data for the purpose of quality control and quality assurance. Pulling together, the book, containing the work carried out by the author's group in India, will be useful to analysts involved in geochemical explorations.
