Abstract: As the upgrade of consumption structure,the demand of meat products in our country is increasing by every year,as well as the safety and quality requirement of meat and meat processing products. However,most hazardous substances occurring during the processing like curing,frying,stewing,roasting may lead to carcinogenicity,which may severely impair consumers' health and inhibit the improvement of meat quality. This research focuses on the common hazardous substances such as biogenic amines,nitrosamines,trans-fatty acids,formaldehyde,hetercyclic aromatic amines and polycyclic aromatic hydrocarbons during meat processing,and analyzes their mechanism,condition and influence factors. By summarizing the research progress of the reduction and control technology of hazardous substances in meat product processing,this research provides the reference for the improvement of the high-quality meat products in our country.
