Seafood Research From Fish To Dish

In this book, scientists from various disciplines address the advances in seafood research with respect to quality, safety, consumer’s demands and processing of wild and farmed fish. The nutritional properties of marine lipids and lipid oxidation from model systems to seafood are presented. Several contributions on the effects of natural anti-oxidants to prevent oxidation are also included. Effects of dietary factors on muscle tissue quality, pre-rigor processing and brining of farmed cod are covered. The development of rigor mortis and the quality of muscle in relation to commercial and experimental slaughter techniques are also discussed. Consumer’s knowledge, perception and need for information about seafood are discussed. Topics such as shelf life and microbial quality of seafood are covered in a range of contributions. Inactivation of micro organisms or biopreservation of seafood are included. Attention is paid to the development of the Quality Index Method for the evaluation of the quality of fresh fish and products. The characterisation and the quality of processed by-products are also presented. The presence of trace elements and organic contaminants in variety of seafood products is highlighted. Finally, several contributions regarding advanced methodologies to determine the quality of seafood are presented. This book will be of interest to anybody concerned with quality and safety of fish throughout the entire chain from catch to consumer.

Inactivation of micro organisms or biopreservation of seafood are included.

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, t

It is widely accepted that increased consumption of seafood is important in dealing with growing health problems such as cardiovascular disease. Based on a major EU Integrated Research Project, SEAFOODplus, this important book reviews the range of research into consumer attitudes towards seafood and the key issues in improving the safety, nutritional and sensory quality of seafood products to meet consumer expectations. After an introductory chapter the book is divided into six parts. The first part of the book reviews consumer attitudes to seafood, including regional differences, the impact of eating quality on product preferences, consumer information needs and attitudes to processed seafood products. Part two discusses research on the important health benefits of seafood consumption in such areas as gastrointestinal health, heart disease and the health of children and young adults. In Part three, the book reviews key seafood safety issues and how they can be managed, from virus contamination and pathogens to histamine and biogenic amines. The following two parts then discuss the range of technologies designed both to optimise the sensory and health benefits of seafood and ensure animal welfare in aquaculture operations. The final part of the book reviews traceability issues. Improving seafood products for the consumer is a valuable reference for the seafood processing industry, and all those concerned with improving the consumption of seafood products. Reviews the range of research into consumer attitudes towards seafood Discusses key issues in improving the safety, nutritional and sensory quality of seafood products Examines the range of technologies available to improve the quality and ensure animal welfare

Fish and seafood are highly perishable, and must be preserved immediately after being caught or harvested. It is very important both to preserving its quality and to ensure that it does not pose any risks to human health upon consumption. Chilling, refrigeration and freezing are the major preservation methods used with seafood and fish products, all three processes aiming to preserve the freshness and flavour of the fish. Consumer demand for fish remains high despite escalating prices in the last ten years which have seen the retail cost of the most popular breeds (cod, haddock, salmon) more than double for unfrozen fish. Many consumers appear to be willing to pay a premium for freshness and quality, both of which are closely linked in shoppers’ minds with the efficient chilling and refrigeration of the fish along the supply chain. At the same time, frozen fish and seafood has also grown more popular with shoppers, as a cheaper, more convenient alternative to refrigerated fresh fish and seafood. Seafood Chilling, Refrigeration and Freezing presents the science behind the chilling, refrigerating and freezing of fish and seafood, describing the chemical, microbiological and physical changes which take place during preservation, and considering the new technologies which can be used, highlighting their benefits and their economic implications. The book takes account of the different requirements for different breeds of fish and seafood, and includes both traditional and novel technologies, providing both current and future perspectives. It will be required reading for food scientists, fish processors and retailers as well as fish specialists, researchers and process designers.

Research and development of seafood continues to be productive in terms of new and improved products for both food and non-food purposes. The use of biotechnology, microbiology, computer modeling and advanced analytical techniques has led to improvements in processing and product safety. This recent book provides extensive new information on these developments. The 25 reports were prepared by food scientists specializing in seafood. The reports are well illustrated with numerous schematics and some micrographs. Extensive reference data is provided in tables and graphs.

An essential part of diverse marine ecosystems, seafood organisms are especially vulnerable to changes in their natural habitats that affect their reproductive abilities, growth rate, and mutual inter- and intra-species interactions. Environmental Effects on Seafood Availability, Safety, and Quality Issues discusses a variety of factors, both intrinsic and extrinsic to the marine environment, and their potential to influence the availability of finfish/shellfish, their nutritional value, quality attributes, and the safety issues at the time of capture. It also covers the handling of newly caught finfish/shellfish aboard the fishing vessel. Edited by experts, with contributions from scientists and practitioners in marine biology/ecology and seafood applied sciences, the book examines direct, short term or indirect, long-term implications on seafood safety and quality caused by seawater pollution/contamination destabilizing marine habitats. It also covers the cumulative effects of toxic compounds in finfish and shellfish tissues and the effects of overfishing such as dead zones, toxic algal blooms, and jellyfish explosions. In addition to the harmful effects of overfishing and environmental pollution/contamination to the productivity and well-being of seafood resources and marine ecosystems in general, the book details how the capture fisheries also suffer from climate change, affecting fish migrations and the stocks accessibility. Overexploitation, overpopulation, and improper human activities result in destruction, shrinkage, fragmentation, and pollution of the natural habitat of marine life, especially the spawning ground. Interdisciplinary in nature, this book elucidates the environmental limitations, the abiotic, biotic, and anthropogenic factors affecting the catch, and the influence of global warming. It offers a smart way to understand and properly use seafood resources in order to maintain sustainable availability of the capture and culture of seafood resources, especially under the contingency of global warming.

Part of the new IFST Advances in Food Science Series, Seafood Processing: Technology, Quality and Safety covers the whole range of current processes which are applied to seafood, as well as quality and safety aspects. The first part of the book (‘Processing Technologies’) covers primary processing, heating, chilling, freezing, irradiation, traditional preservation methods (salting, drying, smoking, fermentation, etc), frozen surimi and packaging. The subjects of waste management and sustainability issues of fish processing are also covered. In the second part (‘Quality and Safety Issues’), quality and safety analysis, fish and seafood authenticity and risk assessment are included.
