Abstract

Introduction

With the globalization of food supply chains, food safety has emerged as a critical global concern impacting public health, well-being, and economic stability. Chemical contaminants such as mycotoxins and heavy metals pose significant health risks, necessitating advanced detection and monitoring strategies to ensure food safety.

Methods

A literature search was conducted in PubMed, Scopus, Web of Science, and ScienceDirect (2010-2025) using keywords like and Relevant studies were screened and reviewed to evaluate recent advancements in analytical technologies and sample preparation methods. Techniques such as SERS, ICP-MS, AFS, and AAS were assessed for sensitivity and accuracy, while novel preparation methods (microwave-assisted digestion, ultrasonic extraction, slurry, and direct solid sampling) were analyzed for efficiency. Speciation analysis of arsenic and mercury was also included to address bioavailability and toxicity.

Results

Advanced analytical methods showed superior sensitivity and rapid detection of trace contaminants. Microwave-assisted digestion and ultrasonic extraction enhanced sample preparation by reducing analyte loss and improving recovery rates. Direct solid sampling (., graphite furnace AAS) and speciation analysis proved critical for assessing toxicological relevance.

Discussion

These findings highlight the potential of integrating cutting-edge analytical technologies and improved sample preparation methods into routine food analysis. They address challenges of trace-level detection and offer strategies for mitigating chemical hazards in the food chain.

Conclusion

Adopting advanced analytical and sample preparation techniques, supported by strengthened regulatory frameworks, is essential to ensuring food quality and safety and protecting public health globally.
