I mainly work in food contact product testing and high-risk substances detection methods research. I work in the performance testing and research of packaging containers, and research on laws and regulations of food contact materials at home and abroad. I have studied rapid detection methods for residual environmental hormones in the interior coatings of food cans, determination of migration of nanoparticles in food packaging materials, and determination of high-risk substances in high-temperature coatings. As the main adult, I formulated 3 national standards and multiple industry standards. I have published more than ten scientific and technological papers and participated in more than ten authorized invention patents and utility model patents.
