Book Description
This book, volume 28 in the Developments in Food Science Series, reviews the latest information and up-to-date concepts concerning a great number of aspects of flavor quality. Particular attention has been afforded to provide a balance between food and beverage chemistry, biochemistry, microbiology, nutritional, processing, packaging, storage, computer applications, and chemometrics. Twenty six specialists were invited to discuss the present state of knowledge in their particular fields. Together with their co-workers (totalling over sixty well known researchers) the authors were drawn from the international spectrum of academia, government institutes, and industry. Their presentations included original research results, background reviews, and comprehensive bibliographies. This informative and well documented book goes a long way to improving the current knowledge in a complex area and certainly increase understanding of taste and odor, flavors and off-flavors of high quality foods and beverages.

Book Description
The Analysis and Control of Less Desirable Flavors in Foods and Beverages contains the proceedings of a symposium held in August 1980 at the Second Chemical Congress of the North American Continent under the auspices of the Agricultural and Food Chemistry Division of American Chemical Society. The papers explore advances in the analysis and control or prevention of less desirable taste and aroma factors in foods and beverages such as fish and shellfish, meat, cheese, soy proteins, corn syrup, water, citrus juices, milk, and beer. This book is comprised of 15 chapters and begins with a review of advances in the separation of volatile components, particularly with respect to gas chromatography. The reader is then introduced to methods and procedures for analysis and control of less desirable flavors in fish and shellfish, meat, cheese, corn syrup, soy proteins, citrus juices, milk, beer, and wine. The analysis and control of taste and odor of public water supplies which are used commonly for food processing and manufacture are also considered. Furthermore, the techniques used to minimize, remove, or mask the bitter flavor that arises unintentionally during enzymatic hydrolysis of proteins are described. This monograph will be a useful resource for students, chemists, and food technologists, as well as growers, processors, fabricated food and beverage manufacturers, brewers, wine makers, distillers, and consumers.

Book Description
Headspace gas analysis is an analytical technique that has been successfully applied to food flavors for over 20 years but has experienced a resurgence of interest and innovation in recent years. In its truest form, headspace analysis represents the direct collection and analysis of the mixture of vapors in the space immediately above a food or beverage. The technique offers several advantages for workers interested in how a product smells and ultimately tastes. It offers the advantages of speed, simplicity, and, more importantly, represents the aroma profile a consumer is likely to experience just before consuming the product. Since only volatile components are collected, the sample is totally free of nonvolatile residues which commonly plague comparison liquid-liquid extracts of the same product. This is the first book devoted to headspace analysis in foods and beverages in more than 20 years. The publication contains chapters on the basic theory of headspace analysis, as well as the theory and application of newly developed headspace techniques, such as solid phase micro extraction, SPME and electronic noses. New concentrating and desorption techniques are described in addition to a raft of food applications including tomato and citrus juices, alcoholic beverages, baguettes, dairy products, lipids, grill flavoring, baked potato, and meat. Chapters on off-flavors as well as aroma-food matrix interactions are also included. "This is the bible of headspace analysis. If you are involved in, or planning on becoming involved, or want to learn more about, this incredible subject , then buy this book immediately!" – Aubrey Parsons, governing council member, International Union for Food Science and Technology

Book Description
Off-flavours and taints are defined as unpleasant odours or tastes, the first resulting from the natural deterioration of a food, the second from its contamination by some other chemical. Both are major problems for the food industry. With its distinguished editor and international team of contributors, this important collection describes some of the most important causes of taints and off-flavours, how they can be identified and dealt with. The book begins with chapters on sensory and instrumental methods for detecting and analysing taints and off-flavours in food. There are chapters on two of the most common causes of taints: packaging and residues from cleaning and disinfection. A number of chapters discuss the various causes of off-flavours, from those caused by microbial action and oxidation to those caused by the Maillard reaction and interactions between food components. With its authoritative coverage, Taints and off-flavours in food is a standard work for the food industry. Describes some of the most important causes of taints and off-flavours in food and outlines how they can be identified and dealt with Reviews the major causes of taints and off-flavours, from oxidative rancidity and microbiologically-derived off-flavours, to packaging materials as a source of taints Discusses the range of techniques for detecting taints and off-flavours, from sensory analysis to instrumental techniques, including the development of new rapid, on-line sensors

Book Description
Contamination of food with extremely low levels of certain compounds can cause an unpleasant taste. This can result in the destruction of vast stocks of product, and very substantial financial losses to food companies. The concentration of the alien compound in the food can be so low that very sophisticated equipment is needed to identify the components and to determine its source. It is vital that every company involved in the production, distribution and sale of foodstuffs are fully aware of the ways in which contamination can accrue, how it can be avoided, and what steps need to be taken in the event that a problem does arise. This book provides the background information needed to recognize how food can become tainted, to draw up guidelines to prevent this contamination, and to plan the steps that should be taken in the event of an outbreak. The new edition has been extensively revised and updated and includes substantial new material on the formation of off flavors due to microbiological and enzymic action, and on sensory evaluation of taints and off flavors A new chapter on off flavors in alcoholic beverages has been added. Written primarily for industrial food technologists, this volume is also an essential reference source for workers in research and government institutions.

Book Description
For a food product to be a success in the marketplace it must be stable throughout its shelf-life. Quality deterioration due to chemical changes and alterations in condition due to physical instability are not always recognised, yet can be just as problematic as microbial spoilage. This book provides an authoritative review of key topics in this area. Chapters in part one focus on the chemical reactions which can negatively affect food quality, such as oxidative rancidity, and their measurement. Part two reviews quality deterioration associated with physical changes, such as moisture loss, gain and migration, crystallization and emulsion breakdown. Contributions in the following section outline the likely effects on different foods and beverages, including bakery products, fruit and vegetables, ready-to-eat meals and wine. With contributions from leaders in their fields, Chemical deterioration and physical instability of food and beverages is an essential reference for R&D and QA staff in the food industry and researchers with an interested in this subject. Examines chemical reactions which can negatively affect food quality and measurement Reviews quality deterioration associated with physical changes such as moisture loss, gain and migration, and crystallization Documents deterioration in specific food and beverage products including bakery products, frozen foods and wine
