Research progress on detection technology of trace polycyclic aromatic hydrocarbons in food

Polycyclic aromatic hydrocarbons (PAHs) are trace hazardous substances that cause food pollution. Accurate and rapid detection of trace PAHs in food is an important technical guarantee for food safety. In this paper, the types of food easily contaminated by PAHs were summarized, and the research progress of PAHs detection technology in food was reviewed. The detection technologies mainly include chromatographic detection, spectral detection and immunological detection. Chromatographic detection is the mainstream detection method of PAHs in food, spectral detection and immunological detection based on its fast and on-site characteristics show a strong application prospect, and the future research trend is prospected.
