Abstract:In recent years, the quality of dairy products has become the core competitiveness of enterprises in the future promotion of consumption. Food additives and illegal additives, residues of pesticides, veterinary medicine, plasticizer and other exogenous risk substances have caused widespread public concern. Therefore, it is of great practical significance and application value to establish screening methods of unknown exogenous risk substances in milk and dairy products. Milk and dairy products have complex components, while exogenous hazardous materials are mostly small molecules and have low contents. Therefore, they require high selectivity and high quality accuracy. High-resolution mass spectrometry allows the qualitative and quantitative analysis of trace components (mg/kg, μg/kg) in complex backgrounds, and it can measure hundreds of compounds at the same time, which greatly improves the detection efficiency. So the high-resolution mass spectrometry meets the demand of instruments for the screening of exogenous risk substances in milk and dairy products. This paper reviews the advantages and applications of high-resolution mass spectrometry screening of exogenous risk substances in milk and dairy products, and the prospective of its future application.
