Summary:

Seafood Authenticity and Traceability: A DNA-Based Perspective is a concise reference to understanding the latest developments in the field. It is written for those interested in food authenticity who may not necessarily have a technical molecular biology background. The book covers methods used for DNA analysis of fish and seafood and provides reviews of the technology and processes for each method. It offers a practical and succinct overview of the relationship between accurate identification, traceability, sustainability, and safety of seafood, including an overview of the supply chain and industry need for improved traceability. Key Features, Presents current and future perspectives in this rapidly emerging field of traceability, Provides solid coverage of DNA analysis for seafood species and origin detection, Includes discussion of implementation of molecular authentication tools throughout the seafood industry Book jacket.
