The work aims to review the research status of the migration of potential hazardous substances in silicone rubber products for food contact to provide references for the revision of relevant regulations. The research progress of the migration of siloxane oligomers, N-nitrosamines and metal elements from food contact silicone rubber products to food simulants and real food were introduced, and the suggestions for reducing the potential hazardous substances in silicone rubber products were put forward. The siloxane oligomers in silicone rubber products for food contact tend to migrate to oil food simulants and high-fat food, and the siloxane oligomers with low molecular weight are more likely to migrate. N-nitrosamines in silicone rubber pacifiers migrate to artificial saliva, and metals in silicone rubber products migrate to acid food simulants. The migration of these substances into food may pose health risks. Therefore, the content of potential hazardous substances in silicone rubber products for food contact needs to be reduced and relevant regulations need to be further improved.
