Examines the interaction of lipid oxidation and Maillard reaction for the generation of flavor compounds. Features new isolation and analysis techniques, including dynamic headspace analysis, to evaluate flavors generated from lipid-containing foods. Discusses the effects of processing and storage on the flavors of processed foods. Examines the generation of flavors from lipoxygenase pathways and the production of flavors by biotechnology.
A much-anticipated revision of a benchmark resource, written by a renowned author, professor, and researcher in food flavors, Flavor Chemistry and Technology, Second Edition provides the latest information and newest research developments that have taken place in the field over the past 20 years. New or expanded coverage includes:Flavor and the Inf
Chemistry, Flavor, and Texture of Lipid-Containing Foods discusses the chemistry and functionality of fat in food sensory perception, and the underlying physicochemical and physiological properties and processes. Fats and oils profoundly affect our sensory perception and appreciation of foods. Fats and oils serve as a source of many flavor compounds, most of which result from oxidation of unsaturated fatty acids. The nose perceives these flavor molecules by chemoreception, and the texture of foods are related to their physicochemical characteristics and structure and thus are perceived by mechanoreception. However, the structural and physicochemical characteristics of fats and oils also strongly influence flavor release. Furthermore, recent studies suggest perception of fats and oils may also be mediated by chemoreception in the oral cavity. While fats and oils have beneficial ingredients because of their energy density, we should minimize their intake because obesity is a serious health risk. Additionally, some types of fat have been found to contribute to arteriosclerosis. Therefore, the food industry is particularly interested in developing foods that have the sensory and hedonic functionality with less fat.
Food may be nutritious, visually appealing and easy to prepare but if it does not possess desirable flavors, it will not be consumed. Food Flavors and Chemistry: Advances of the New Millennium primarily focuses on food flavors and their use in foods. Coverage also includes other important topics in food chemistry and production such as analytical methods, packaging, storage, safety and patents. Positive flavor notes are described, including ways of enhancing them in food. Conversely, methods for eliminating and reducing undesirable flavors are also proposed. Packaging aspects of foods, with respect to controlling sensory attributes, appearance and microbiological safety are discussed in detail. There is also a section concentrating on the most recent developments in dairy flavor chemistry. This book will be an important read for all postgraduate students, academics and industrial researchers wanting to keep abreast of food flavors and their chemistry.
Celebrating the founding of the Flavor Subdivision of the Agriculture and Food Chemistry Division of the American Chemical Society, this book provides an overview of progress made during the past 30-40 years in various aspects of flavor chemistry as seen by internationally renowned scientists in the forefront of their respective fields. In addition, it presents up-to-date findings in the areas of flavor chemistry, analytical methods, thermally produced flavors and precursors, enzymatically produced flavors and precursors, and sensory methods and results.
This is a basic reference/textbook for professionals and students involved with these important oils and fats. It is a valuable source of information for those preparing for or already professionally as sociated with the Food Processing and Foodservice industries. Chapters one through six deal with the technology of oils and fats, including sources, chemical structure, physical and chemical properties, and processing techniques. Chapters seven through twelve are devoted to the utilization of oils and fats in Food Manufacturing and Foodservice, including deep frying, griddling, baking of all types, salad dressings, margarines, hard butters, and dairy product re placements. The last four chapters contain a most complete and up to-date treatment of nutrition, as well as the latest developments in analytical methods, flavor, and product development as they relate to oils and fats. This book contains the necessary information for an understand ing of how oils and fats are used in the food industry and how this information is used to set standards and meet performance goals. In a thoroughly readable way it is a how-to-do, hands-on treatise on using oils and fats for every major food use. ix Acknowledgments I gratefully acknowledge many friends at Procter & Gamble who provided updated material, some currently employed and some re cently retired. Fred J. Baur, formerly of Procter & Gamble, wrote the updated chapters related to Analytical Methods, Flavor, Nutri tion, and Dietary Considerations.
Lipids in Foods: Chemistry, Biochemistry and Technology provides basic information on the biochemistry and technology of the fatty acids or lipids. This book notes that natural and processed fats and oils, whether of animal or vegetable origin, play a significant role in the economy of several countries including both oil-producers and oil-users. These materials are used extensively, but not exclusively, in the food industry. The first 10 chapters cover the basic chemistry and biochemistry of the fatty acids and their natural derivatives. These topics include an account of the chemical structure, separation, analysis, biochemistry, physical properties, chemical properties, and synthesis of these compounds. The remaining chapters include the recovery of fats and oils from their sources and the processes of refining, bleaching, hydrogenation, deodorization, fractionating, and interesterification. A segment is devoted to margarines and shortenings and to the problems of flavor stability and antioxidants. This text will be valuable to students wishing to know more about lipids and to those involved in this field of study.
