Book

In an era of increasingly complex global food systems, ensuring the authenticity of meat products has never been more critical. DNA-Based Methods for Meat Species Authentication in Complex Food Matrices offers a rigorous and comprehensive guide to one of the most powerful tools in modern food science—molecular identification through DNA analysis. This reference work addresses the growing challenges of food fraud, species substitution, and mislabeling, particularly in highly processed products where traditional identification methods fail. By leveraging the stability and specificity of DNA, scientists and regulators can detect even trace amounts of undeclared species, safeguarding public health, religious compliance, and consumer trust. The book systematically explores the scientific foundations of species identification, from genome organization and mitochondrial DNA to advanced target selection strategies. It provides detailed, practical guidance on DNA extraction from challenging food matrices, overcoming PCR inhibitors, and ensuring analytical reliability. Core molecular techniques—including conventional PCR, real-time PCR, DNA barcoding, next-generation sequencing, and emerging digital and biosensor technologies—are presented with both theoretical depth and protocol-level clarity. Each method is critically evaluated in terms of sensitivity, specificity, limitations, and real-world application. Special emphasis is placed on complex food systems such as processed meats, emulsified products, fermented foods, and multi-ingredient formulations, where degraded DNA and inhibitory compounds demand advanced methodological approaches. Bridging research and application, this book also addresses quality assurance, method validation, regulatory frameworks, and laboratory implementation strategies, making it an essential resource for food scientists, regulatory authorities, academic researchers, and industry professionals. By integrating scientific rigor with practical insight, this volume serves as a definitive reference for advancing transparency, integrity, and trust in the global food supply.
