Comparative analysis of limit standards for contaminants in edible vegetable oils between domestic and international regulations

This paper conducts a comprehensive comparison and analysis of domestic and international standards pertaining to high-risk contaminants in edible vegetable oils， including solvent residues， polycyclic aromatic hydrocarbons， mycotoxins， heavy metals， 3-chloropropanol esters， and glycerol esters. The objective is to establish a scientific foundation for the revision of relevant standards in China. By conducting an in-depth investigation into the sources of these contaminants and systematically sorting and comparing domestic and international standards， the study uncovers inherent discrepancies between China’s standards and those at the international level. The research summarizes the strengths and weaknesses of China’s edible vegetable oil pollutant limit standards and proposes targeted revision suggestions. Ultimately， the findings aim to provide technical support for the enhancement of China’s edible vegetable oil pollutant limit standard system， thereby ensuring the healthy and stable development of the edible oil market.
