Application of electrochemical luminescence method in food analysis

With the development of society, the change of environmental and the progress of human life, food safety issue has received more and more attention. Food is the paramount necessity of the people. The study of food detection method is closely related to the solution of food safety. There are many methods for food detection, such as high performance liquid chromatography, enzyme-linked immunosorbent assay, fluorescence polarimetric method, spectrophotometry and so on. Electrochemical luminescence analysis is a combination of electrochemical analysis and chemiluminescence, with low background noise, high sensitivity, good selectivity, controllability and simple equipment. It has been widely used in the detection of food nutrition, food additives and food contamination. This paper mainly introduced the application of electrochemical luminescence analysis in food detection, including the analysis of nutrients, organic pollutants, inorganic compounds, pathogens in food and other aspects of the application in food detection, and summarized the development trend and prospect of electrochemical luminescence analysis.
