This book offers a state-of-the-art analysis on the main challenges facing the aquatic products processing industry. The topics explored are particularly relevant to the issues faced by European consumers and processors, but the information provided within this book can be widely extrapolated.
This book should be helpful for processors, fish traders, consumers, scientists and students. The first chapter is dedicated to the sociological definition of "fish" and consumers’ perceptions. The following chapters deal with the notions of quality sensu lato, biological risks and their control, as well as the risks linked to the pollution of oceans and ecosystems by microplastics. Two types of processes and processed products - smoked fish and surimi products - which are of great economic importance to the European market, are also presented. The process of adding value to co-products, including the "blue biorefinery" and the innovative pH-shift technology are also covered in this book.
