Application of Surface-Enhanced Raman Spectroscopy in Food Safety

Abstract

Food safety is the primary concern because people are the foundation of a nation's strength and food is their most basic necessity. The value of food security as a global issue today captures people's attention. Food testing technologies are therefore essential for guaranteeing food safety. Traditional procedures for identifying biological, chemical, and physical pollutants in food are time-consuming, costly, and labor-intensive, and frequently cause food samples to change. These restrictions have made it necessary for the food sector to create more useful food detection systems that can accurately identify all three main categories of contaminants. Raman spectroscopy can be used extensively in evaluating food safety since it is non-destructive, easy to use, sensitive, and efficient. The advancement of Raman spectroscopy in recent years has substantially boosted its use relating to food security, enhancing the identification of contaminants in food product as well. This article describes surface-enhanced Raman spectroscopy (SERS), Raman spectroscopy, and the fundamental imaging principles. It also discusses recent developments in the identification of different material in foods. Finally, a discussion of the limitations and further potential of approaches concerning Raman spectroscopy in food security monitoring follows.
