Book Description
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.

Bio-Farms for Nutraceuticals
Author: Maria Teresa Giardi
Publisher: Springer Science & Business Media
ISBN: 1441973478
Category : Medical
Languages : en
Pages : 360
Book Description
"Bio-Farms for Nutraceuticals" can be said to have been born of the NUTRA-SNACKS project within the Sixth Framework Programme Priority on Food Quality and Safety. One objective of NUTRA -SNACK S was to improve the nutritional and eating properties of ready-to-eat products and semi-prepared foodstuffs through better monitoring of the quality and safety of raw materials and the development of innovative processes along the production chain. Another main objective of the project was the production of ready-to-eat snacks with high nutraceutic activity. Seven research institutes and three companies in six European countries were involved in this effort. The co-operation resulted in the production of food having a high content of natural metabolites with the following beneficial health effects: anticancer, antilipidemic, anticholesterol, antimicrobial, antibacterial, antifungal, antiviral, antihypertensive, anti-inflamatory and antioxidant activities.

Handbook of Antioxidants for Food Preservation
Author: Fereidoon Shahidi
Publisher: Woodhead Publishing
ISBN: 1782420975
Category : Technology & Engineering
Languages : en
Pages : 515
Book Description
Lipid oxidation in food leads to rancidity, which compromises the sensory properties of food and makes it unappealing to consumers. The growing trend towards natural additives and preservatives means that new antioxidants are emerging for use in foods. This book provides an overview of the food antioxidants currently available and their applications in different food products. Part one provides background information on a comprehensive list of the main natural and synthetic antioxidants used in food. Part two looks at methodologies for using antioxidants in food, focusing on the efficacy of antioxidants. Part three covers the main food commodities in which antioxidants are used. - Reviews the various types of antioxidants used in food preservation, including chapters on tea extracts, natural plant extracts and synthetic phenolics - Analyses the performance of antixoxidants in different food systems - Compiles significant international research and advancements
