Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This well-known and highly successful book was first published in 1973 and has been completely re-written in subsequent editions (published in 1982 and 2003). This new Fourth Edition has become necessary because of the pace of developments in mass spectrometry of intact lipids, which has given recognition of lipid analysis and 'lipidomics' as a distinct science. To bring the book up to date with these developments, author William W. Christie is joined by co-author Xianlin Han. Although devoting considerable space to mass spectrometry and lipidomics, Lipid analysis remains a practical guide, in one volume, to the complexities of the analysis of lipids. As in past editions, it is designed to act as a primary source, of value at the laboratory bench rather than residing on a library shelf.Lipid analysis deals with the isolation, separation, identification and structural analysis of glycerolipids, including triacylglycerols, phospholipids, sphingolipids, and the various hydrolysis products of these. The chapters follow a logical sequence from the extraction of lipids to the isolation and characterization of particular lipid classes and of molecular species of each, and to the mass spectrometric analysis of lipids and lipidomics.The new influence of mass spectrometry is due mainly to the development of electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). Most emphasis in this book is placed on ESI, which is enabling structural characterization of different lipid classes and the identification of novel lipids and their molecular species. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Phospholipid technology and applications is an essential reference for technologists developing food and cosmetics products, scientists researching phospholipids in biological and food systems, technologists in fats and oils refining, and scientists developing drugs and drug delivery systems and carriers.The major source of phospholipids is the lecithin recovered during degumming of vegetable oils, particularly soybean oil. This crude material finds uses in its own right but can be purified through a series of processes which eventually lead to individual phospholipid classes such as phosphatidylcholines.It is widely accepted that oil and water do not mix but there are several areas in science and technology where these two distinct phases must coexist in stable emulsions. This is achieved by admixture of amphiphilic molecules of which the phospholipids are important natural examples. Today, phospholipids find many uses in the food industry and in other industries which exploit the amphiphilic nature of these compounds. Further, there are now important procedures by which their amphiphilicity can be optimized for different uses.The early chapters in this book are devoted to the more common glycerol-based phospholipids and cover their structure, source, composition, modification by chemical and enzymatic methods, their physical, chemical, and nutritional properties, and their major uses. The final chapter is devoted to another kind of phospholipid, the sphingolipids, in which there is a growing interest. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this completely rewritten Second Edition of Trans Fatty Acids in Human Nutrition authors who are recognised international authorities in their field have addressed the major areas of trans fatty acids (TFA) research such as consumption, analysis, biochemistry, synthesis and natural TFA biosynthesis, health effects, food formulation, and also regulation and consumer perception. Each chapter contains the latest references and major advances and breakthroughs in a specific area of trans fatty acids research. Furthermore, the book also includes a discussion of a major issue - the health effects of the natural trans isomers, comparing their effects to those observed for TFA produced during hydrogenation.The availability of so much information in a single volume will help to clarify the major effects of TFA in human nutrition that have been discovered over the last two decades. This book guides the next generation of scientists to the important opportunities for making further progress in this challenging field of research.The First Edition of Trans Fatty Acids in Human Nutrition carried out a very similar task for the state of our knowledge in the late 1990s but the rapid expansion and progress in the subject meant that it had to be completely re-written and expanded from the original nine to the present fifteen chapters of the Second Edition.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fat is the most expensive component in confectionery such as chocolate. It may comprise of cocoa butter, milk fat, palm oil, lauric oil, exotic fats, etc. This new handbook, with a large number of figures and tables, provides a comprehensive guide to all aspects of confectionery fats, with particular emphasis on the later. Unlike sugar confectionery, chocolate is a fat-continuous product and the sugar, like the other non-fat components, is merely mixed with the fat rather than melted/boiled. The properties of chocolate confectionery are thus determined mainly by the fat, which comprises about 26-35% in a typical chocolate formulation.The book describes the essential physical chemistry needed to understand the properties of confectionery fats, analytical methods, raw materials, the production and properties of confectionery fats, and their application in sugar and chocolate confectionery. It concludes with consideration of legislation and regulatory aspects of producing confectionery and of using milk fat, cocoa butter and alternative fats together with a chapter on analytical methods for detecting and quantifying confectionery fats. Finally, four appendixes provide: a glossary of terms and abbreviations used; details of confectionery fat manufacturers; details of confectionary fat products produced by these manufacturers; and a list of websites from other relevant organizations that the reader may find useful.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.
