Fingerprinting Techniques in Food Authentication and Traceability of Marine Species

ByAbdul Moheman, Showkat Ahmad Bhawani, Ahmad Husaini, Mohammad Sarwar Alam, Abu Tariq

This chapter provides a comprehensive and critical overview of the application of the different fingerprinting techniques such as electrophoretic fingerprinting, spectral fingerprinting, chromatographic fingerprinting and sensor fingerprinting to determine freshness, authenticity, quality, and safety parameters of fish and other marine species. It explains polymerase chain reaction (PCR)-based fingerprinting method is reliable, effective and therefore, could be employed for routine marine species analysis. PCR-based fingerprinting methods are fast, extremely sensitive, and are widely used in marine food authentication. The chapter deals with fingerprinting including spectroscopic and instrumental sensory techniques combined with chemometric tools provides new possibilities of analysis data without any prior information. It presents a picture of the fingerprinting techniques and comprehensive knowledge used for marine food species authentication and traceability, consequently facilitating to support future developments in the marine food industry. DNA-based fingerprinting methods are generally more advantageous and are widespread in species authentication and traceability of marine food products.
