Spectroscopy food functionality and safety

In the modern age of heightened food consumption, consumers are increasingly focused on the safety and quality of the products they consume. Consequently, food regulatory authorities are rigorously overseeing the industry to ensure compliance with established quality standards. Evaluating food properties involves a broad range of factors, including chemical and physical characteristics, sensory evaluation, authenticity verification, traceability, production processes, storage conditions, and the detection of microbes and contaminants. While traditional analytical methods have been the cornerstone of such evaluations, they are often destructive, resource-intensive, time-consuming, costly, and environmentally unfriendly. On the other hand, advanced spectroscopic techniques present a highly efficient and non-invasive alternative for food analysis. Spectroscopy, as a versatile analytical tool, plays a critical role in advancing the understanding of food functionality and ensuring food safety. This chapter explores the application of spectroscopic techniques in characterizing food components, monitoring quality, detecting contaminants, and assessing safety. By combining technical insights with practical applications, the chapter provides a roadmap for integrating spectroscopy into contemporary food science research and industry practices.
