Determination of Maleic acid in solution and food additives by fluorescence

Abstract:

In the face of ever-increasing food safety issues, the detection of bad additives is critical. In order to achieve the effective detection of maleic acid in food additives, we propose to use compound 1 (2,2’-diformyl-1,1’-binaphthyl) to indentify maleic acid by fluorescent. The conditions of fluorescence detection are explored in detail in detail, and the results show that the best fluorescence enhancement effect is obtained in methanol. The calculations predict the low detection limit (1.3×10-7 mol/L), which indicates that it has potential application prospect. Finally, maleic acid in starchy foods was successfully detected by using this probe.
