Fish and marine invertebrates are important sources of nutrients for the world's population, and many species have exceptionally high market value because of their exquisite sensory properties. Both the utilization of the available catch in different forms and the market price are affected by the quality of the fish. Proteins and nonprotein nitroge nous compounds playa crucial role in the nutritional value and sensory quality of seafoods as well as in the suitability of different species to various forms of processing, preservation, and use in other branches of the food industry. This role of proteins results from their basic chemical and biochemical properties and functions in different tissues. A presenta tion of the actual state of knowledge on seafood nitrogenous compounds in one volume may contribute to a better understanding of the involve ment of these components in all stages of handling and processing fish. It has been possible to prepare this text thanks to the cooperative effort of an international group of specialists. The editors of the book are greatly indebted to all colleagues who have willingly contributed to this volume, sharing their knowledge and experience, as well as to all persons who have granted permission to use their previously published materials. viii Preface ix A large part of the book has been prepared during my sabbatical in the Department of Marine Food Science, National Taiwan Ocean University (NTOU) in Keelung, Taiwan.
Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.

This must-have resource focuses on marine food composition as it relates to nutrition. Filled with illustrations and graphs, it describes the biological and technical factors which effect the availability and quality of seafood resources and provides information on the biochemical changes, functional properties, contents, and biological value of the main components of the major marine food organisms. It presents the yield of edible parts for the different species and the applied procedures of processing and culinary preparation. This volume is intended for the general reader who is interested in food production, marketing, and nutrition, and is also an ideal text for students of food science as well as professionals in the food trade and fish industry.
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.
Traditionally a source of nutrition, proteins are also added to foods for their ability to form gels and stabilise emulsions, among other properties. The range of specialised protein ingredients used in foods is increasing. Handbook of food proteins provides an authoritative overview of the characteristics, functionalities and applications of different proteins of importance to the food industry in one convenient volume.The introductory chapter provides an overview of proteins and their uses in foods. The following chapters each focus on a particular protein ingredient or group of ingredients covering their origins, production, properties and applications. The proteins discussed are caseins, whey proteins, gelatin and other meat-derived protein ingredients, seafood proteins, egg proteins, soy proteins, pea and other legume proteins, mycoprotein, wheat gluten, canola and other oilseed proteins, algal proteins and potato protein. A chapter on texturised vegetable proteins completes the volume. Innovative products and potential methods for improving nutrition and diet using these proteins are described.With its distinguished editors and international team of expert contributors Handbook of food proteins is an invaluable reference tool for professionals using food protein ingredients for both food and other applications. - An authoritative overview of the characteristics, functionalities and applications of different proteins of importance to the food industry - Chapters each focus on a particular protein ingredient or group of ingredients - Innovative products and potential methods for improving nutrition and diet using proteins is also described
This book explores current trends in seafood science and examines various related topics including isolation aspects and different methodologies involved in seafood production. It provides detailed explanations about marine species such as fish, seaweed, and crustaceans and discusses their health benefits as well as the health risk for consumption. These topics provide a platform to develop various aquaculture/biotechnology studies. The book is essential reading for the novice and expert in marine-related fields such as aquaculture, as well as those in biotechnology, chemical sciences, natural products, materials science, pharmaceutical science, and nutraceutical science.
The seafood processing industry produces a large amount of by-products that usually consist of bioactive materials such as proteins, enzymes, fatty acids, and biopolymers. These by-products are often underutilized or wasted, even though they have been shown to have biotechnological, nutritional, pharmaceutical, and biomedical applications. For example, by-products derived from crustaceans and algae have been successfully applied in place of collagen and gelatin in food, cosmetics, drug delivery, and tissue engineering. Divided into four parts and consisting of twenty-seven chapters, this book discusses seafood by-product development, isolation, and characterization, and demonstrates the importance of seafood by-products for the pharmaceutical, nutraceutical, and biomedical industries.
Considered Mother Nature's medicine cabinet in many areas of the world, marine organisms have been known from time immemorial to possess curative powers. But until recently, their bioactive compounds, nutraceutical properties, and commercial potential remained undiscovered. Bringing together widely scattered literature, Marine Products for Healthca
