The book discusses the present strategies towards antioxidant capacity evaluation including optical, chromatography, electrochemical methods as well as photoelectrochemical technique, where the advantages, limitations and different applications are analyzed and compared. Subsequently, the corresponding analysis instruments are introduced and interpreted combining with their technical characteristics, scope and performance indicators.
A comprehensive reference for assessing the antioxidant potential of foods and essential techniques for developing healthy food products
Measurement of Antioxidant Activity and Capacity offers a much-needed resource for assessing the antioxidant potential of food and includes proven approaches for creating healthy food products. With contributions from world-class experts in the field, the text presents the general mechanisms underlying the various assessments, the types of molecules detected, and the key advantages and disadvantages of each method. Both thermodynamic (i.e. efficiency of scavenging reactive species) and kinetic (i.e. rates of hydrogen atom or electron transfer reactions) aspects of available methods are discussed in detail.
A thorough description of all available methods provides a basis and rationale for developing standardized antioxidant capacity/activity methods for food and nutraceutical sciences and industries. This text also contains data on new antioxidant measurement techniques including nanotechnological methods in spectroscopy and electrochemistry, as well as on innovative assays combining several principles. Therefore, the comparison of conventional methods versus novel approaches is made possible. This important resource:
Offers suggestions for assessing the antioxidant potential of foods and their components
Includes strategies for the development of healthy functional food products
Contains information for identifying antioxidant activity in the body
Presents the pros and cons of the available antioxidant determination methods, and helps in the selection of the most appropriate method
Written for researchers and professionals in the nutraceutical and functional food industries, academia and government laboratories, this text includes the most current knowledge in order to form a common language between research groups and to contribute to the solution of critical problems existing for all researchers working in this field.
Описание: Oxidative rancidity is a major cause of food quality deterioration, leading to the formation of undesirable off-flavours as well as unhealthful compounds. Antioxidants are widely employed to inhibit oxidation, and with current consumer concerns about synthetic additives and natural antioxidants are of much interest. The two volumes of Oxidation in foods and beverages and antioxidant applications review food quality deterioration due to oxidation and methods for its control.The first volume focuses on oxidation mechanisms and antioxidant activity. Initial chapters in part one describe oxidation processes in foods, including the role of metals, heme proteins and lipoxygenase. The impact of oxidation on food flavour and the health aspects of oxidized fats are also covered. Final chapters in part one review the measurement of the extent of lipid oxidation and methods for food shelf-life determination. Part two discusses the ways in which antioxidants inhibit food oxidation, factors affecting antioxidant efficacy, methods to measure antioxidant activity and novel antioxidants.With its distinguished international team of editors and contributors, the two volumes of Oxidation in foods and beverages and antioxidant applications is standard references for R&D and QA professionals in the food industry, as well as academic researchers interested in food quality.
