Available in PDF, EPUB and Kindle. Book excerpt: Processing and Impact on Antioxidants in Beverages presents information key to understanding how antioxidants change during production of beverages, how production options can be used to enhance antioxidant benefit, and how to determine the production process that will result in the optimum antioxidant benefit while retaining consumer acceptability. In the food industry, antioxidants are added to preserve the shelf life of foods and to prevent off-flavors from developing. These production-added components also contribute to the overall availability of essential nutrients for intake. Moreover, some production processes reduce the amount of naturally occurring antioxidants. Thus, in terms of food science, it is important to understand not only the physiological importance of antioxidants, but what they are, how much are in the different food ingredients, and how they are damaged or enhanced through the processing and packaging phases. This book specifically addresses the composition and characterization of antioxidants in coffee, green tea, soft drinks, beer, and wine. Processing techniques considered here include fermentation and aging, high-pressure homogenization, enzymatic debittering, and more. Lastly, the book considers several selective antioxidant assays, such as Oxygen Radical Absorbance Capacity (ORAC) and Trolox Equivalent Antioxidant Capacity (TEAC) assays. Provides insights into processing options for enhanced antioxidant bioavailability Presents correlation potentials for increased total antioxidant capacity Includes methods for the in situ or in-line monitoring of antioxidants to reduce industrial loss of antioxidants in beverages Proposes processing of concentrated fractions of antioxidants that can be added to foods

Available in PDF, EPUB and Kindle. Book excerpt: From beef to baked goods, fish to flour, antioxidants are added to preserve the shelf life of foods and ensure consumer acceptability. These production-added components may also contribute to the overall availability of essential nutrients for intake as well as the prevention of the development of unwelcome product characteristics such as off-flavours or colours. However, there are processes that reduce the amount of naturally occurring antioxidants and awareness of that potential is just as important for those in product research and development. There is a practical need to understand not only the physiological importance of antioxidants in terms of consumer health benefit, but how they may be damaged or enhanced through the processing and packaging phases. This book presents information key to understanding how antioxidants change during production of a wide variety of food products, with a focus toward how this understanding may be translated effectively to other foods as well. Addresses how the composition of food is altered, the analytical techniques used, and the applications to other foods Presents in-chapter summary points and other translational insights into concepts, techniques, findings and approaches to processing of other foods Explores advances in analytical and methodological science within each chapter

Download or read book Effects of Thermal Processing on Antioxidant Phenolic and Anthocyanin Levels in Blackcurrant Juice written by Bridget A. Skahill and published by . This book was released on 2009 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Health and Wellness continues to be a major driver for consumers within the current marketplace. Given this climate, superfruits such as blackcurrant (Ribes nigrum) are gaining interest among beverage manufacturers due to their high content of antioxidants and anthocyanins. Blackcurrant juice, while very popular in Europe, is just beginning to gain acceptance in the domestic marketplace. Various thermal processes are required throughout the production of a shelf stable juice product at both the raw material and finished beverage stages. The goal of this research is to evaluate the effect of these thermal processes on the retention of heat sensitive compounds such as phenolics, anthocyanins and overall antioxidants in the final consumer beverage. To this end, bulk samples of 13 brix flash pasteurized and 65 brix concentrated blackcurrant juice were obtained and further processed at beverage scale. The beverage scale processing entailed the three key thermal processes utilized by retail manufacturers: aseptic, hotfill and tunnel pasteurization. The raw material juices and fully processed samples were then analyzed for anthocyanin content, total phenolic content and antioxidant capacity to understand retention of these nutrients in the post process beverage. The findings of this study show marked losses at the raw material level of all measured components with a reduction in Phenolic Content of approximately 35%, a reduction of Antioxidant Capacity by 48% and, most significantly, a reduction of Anthocyanin Content of approximately 80% in the concentrated juice as compared to the flash pasteurized Not From Concentrate (NFC) juice. The anthocyanin content was seen to undergo additional degradation (40-50%) by further processing the juice at beverage level, while little or no further change in either antioxidant capacity or phenolic content was seen. There was little to no difference in the impact of aseptic, hotfill or tunnel pasteurization as compared to each other. Understanding the relationship between process and retention will allow industry to leverage the proper processes required to deliver the desired health benefits to consumers.

This book was released on 2013-06-29 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.

Available in PDF, EPUB and Kindle. Book excerpt: Food antioxidants are of primary importance for the preservation of food quality during processing and storage. However, the status of food depends on a balance of antioxidants and prooxidants occurring in food. Food Oxidants and Antioxidants: Chemical, Biological, and Functional Properties provides a single-volume reference on the effects of naturally occurring and process-generated prooxidants and antioxidants on various aspects of food quality. The book begins with a general introduction to oxidation in food and then characterizes the main oxidants present in food, including enzymatic oxidants. Chapters cover oxidation potential, mechanisms of oxidation of the main food components (proteins and lipids), addition of exogenous oxidants during food processing, and the effects of physical agents such as irradiation, freeze-thawing, and high hydrostatic pressure during processing. The book also discusses the effects of oxidation on sensory characteristics of food components and analyzes how oxidation and antioxidants affect the nutritive and health-promoting features of food components. The text examines natural antioxidants in food, including lesser-known ones such as amino acids and polysaccharides, antioxidants generated in food as a result of processing, mechanisms of antioxidant activity, and measurement of antioxidant activity of food components. It explores the bioavailability of curcuminoid and carotenoids antioxidants and presents case studies on natural food antioxidants, presenting novel extraction methods for preservation of antioxidant activity. The final chapters address functional antioxidant foods and beverages as well as general ideas on the effects of food on the redox homeostasis of the organism.

Download or read book Antioxidants in Foods and Its Applications written by Emad Shalaby and published by BoD – Books on Demand. This book was released on 2018-07-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radicals are atoms or molecules containing unpaired electrons. Damage occurs when the free radical encounters another molecule and seeks to find another electron to pair its unpaired electron. Free radicals can cause mutation in different biological compounds such as protein, nucleic acids, and lipids, and the damage caused by the free radicals lead to various diseases (cancer, cardiovascular disease, aging, etc.). Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons, which neutralize the radical without forming another. Ascorbic acid, for example, can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule. Unfortunately, new data indicate that the synthetic antioxidants used in the industry could have carcinogenic effects on human cells, thus fueling an intense search for new, natural, and efficient antioxidants. Therefore, the current book discusses the role and source of antioxidant compounds in nutrition and diets. Also, the current book includes nine chapters contributed by experts around the world, and the chapters are categorized into two sections: "Antioxidant Compounds and Biological Activities" and "Natural Antioxidants and Applications."
