Optimization and Practical Evaluation of Multiplex PCR Technology for Toxin Detection in Food Science

The optimization of multiplex PCR technology involves factors such as primer specificity, annealing temperature, and buffer concentration. This paper discusses the optimization process of the technology and its performance evaluation in practical detection. The objective of the study is to enhance the sensitivity, specificity, and stability of multiplex PCR technology to more efficiently detect harmful substances in food. The research systematically evaluates the performance of the optimized PCR system by optimizing parameters such as primer design, annealing temperature, and buffer concentration. The sensitivity and specificity of the optimized technique are validated through experimental data, demonstrating advantages in stability and reproducibility. In practical applications, the optimized technology was tested on food samples, providing specific data analysis and comparing its performance with existing detection methods. A comprehensive evaluation of multiplex PCR's application value in terms of detection time, cost, and efficiency was conducted. The results show that the optimized multiplex PCR technology improves the detection sensitivity to 0.1 pg/L, with specificity exceeding 98%, along with lower background signals and higher stability. The widespread application of this technology is expected to provide a faster, more accurate, and cost-effective detection method for food safety testing.
