Evaluation Of Seafood Freshness Quality

Durch den Anwuchs internationaler Märkte für Frischfisch und andere Meeresfrüchte und der einhergehenden Zunahme der verarbeitenden Industrie ist die Bestimmung und die Vorhersage der Qualität von Seefisch und anderen Meeresfrüchten ein ganz aktuelles Thema. Immer häufiger wird Fisch auf langen Transportwegen verfrachtet, bei denen die permanenten Qualitätskontrollen eine wichtige Rolle spielen. Der Autor des Buches hat fast zwei Jahrzehnte Erfahrung in der Qualitätsbestimmung und faßt in diesem Werk das wichtigste Wissen praxisorientiert zusammen. Das Buch ist für alle die nützlich, die in Verwaltung, Wissenschaft und Industrie mit den Qualitätsuntersuchungen von Meeresfrüchten konfrontiert sind.

The global market for seafood products continues to increase year by year. Food safety considerations are as crucial as ever in this sector, and higher standards of quality are demanded even as products are shipped greater distances around the world. The current global focus on the connection between diet and health drives growth in the industry and offers commercial opportunities on a number of fronts. There is great interest in the beneficial effects of marine functional compounds such as omega-3 polyunsaturated fatty acids. Seafoods are well-known as low calorie foods, and research continues into the nutritional effects on, for example, obesity and heart disease. In addition, by-products of marine food processing can be used in nutraceutical applications. This book is a resource for those interested in the latest advances in the science and technology of seafood quality and safety as well as new developments in the nutritional effects and applications of marine foods. It includes chapters on the practical evaluation of seafood quality; novel approaches in preservation techniques; flavour chemistry and analysis; textural quality and measurement; packaging; the control of food-borne pathogens and seafood toxins. New research on the health-related aspects of marine food intake are covered, as well as the use of seafoods as sources of bioactives and nutraceuticals. The book is directed at scientists and technologists in academia, government laboratories and the seafood industries, including quality managers, processors and sensory scientists.

New research and development in biotechnology, microbiology, computer modeling and advanced analytical techniques has led to improvements in processing and product safety. This new book provides extensive new information on these developments, as well as research directions and challenges for the future.

Seafoods covers selected but vital topics of fish processing with an emphasis on quality, technology and nutraceutical applications in an up-to-date survey. The aspects of seafood quality covered range from the impact of slaughter procedures, through protein functionality, texture, flavour, histamine toxicity to the practical evaluation of quality and measurement. Technological aspects concentrate on automation in processing, waste-water treatment and reuse of scraps. Marine nutraceuticals/functional foods are discussed in detail. This book is highly recommended for scientists and technologists in the seafood industries, plus fish processing professionals, quality managers, and nutritonists..

Seafood and seafood products represent some of the most important foods in almost all types of societies around the world. More intensive production of fish and shellfish to meet high demand has raised some concerns related to the nutritional and sensory qualities of these cultured fish in comparison to their wild-catch counterparts. In addition, the variety in processing, preservation, and storage methods from traditional to modern is contributing to an increase in variability in consumer products. This second edition of the Handbook of Seafood and Seafood Products Analysis brings together the work of 109 experts who focus on the most recent research and development trends in analytical techniques and methodologies for the analysis of captured fresh and preserved seafood, either cultivated or wild, as well as for derived products. After providing a general introduction, this handbook provides 48 chapters distributed in six sections: Chemistry and biochemistry focuses on the analysis of main chemical and biochemical compounds of seafood. Processing control describes the analysis of technological quality and the use of some non-destructive techniques as well as methods to check freshness, detection of species, and geographic origin and to evaluate smoke flavoring. Nutritional quality deals with the analysis of nutrients in seafood such as essential amino acids, bioactive peptides, antioxidants, vitamins, minerals and trace elements, and fatty acids. Sensory quality covers the sensory quality and main analytical tools to determine color, texture, flavor and off-flavor, quality index methods as well as sensory descriptors, sensory aspects of heat-treated seafood, and sensory perception. Biological Safety looks at tools for the detection of spoilage, pathogens, parasites, viruses, marine toxins, antibiotics, and GM ingredients. Chemical Safety focuses on the identification of fish species, detection of adulterations, veterinary drug residues, irradiation, food contact materials, and chemical toxic compounds from the environment, generated during processing or intentionally added. Key Features: This comprehensive handbook provides a full overview of the tools now available for the analysis of captured fresh and preserved seafood, either cultivated or wild, as well as for derived products. This is a comprehensive and informative book that presents both the merits and limitations of analytical techniques and also gives future developments for guaranteeing the quality of seafood and seafood products. This cutting-edge work covers processes used from all of the seven seas to ensure that consumers find safe, nutritionally beneficial, and appealing seafood products at their markets and restaurants. This handbook covers the main types of worldwide available analytical techniques and methodologies for the analysis of seafood and seafood products.

The best-selling first edition of this contributed book established itself as a highly practical and authoritative source of information on shelf-life evaluation. Every food manufacturer is concerned about shelf life, as are the major retailers and ingredient suppliers. Increasing consumer interest in food safety, quality and date marking, competitive pressures from retailers and extensive legislative changes have combined to give this subject new significance. A proper evaluation of shelf life must be grounded on sound scientific prinicles, supported by up-to-date techniques. This book begins with six chapters reviewing the principles of shelf-life evaluation, followed by ten chapters on a number of selected food products such as chilled yogurt and other dairy desserts, seafood, and meat. The latest edition has been expanded to include new chapters on HACCP, preservation technology and shelf life, and minimally processed, ready-to-eat ambient-stable meat products. Sufficient information on the principles and practice of shelf life evaluation has been included for the beginner as well as for those who are more experienced in this area.
