Abstract Using amino silica modified with fluorescein isothiocyanate (FITC), a quick fluorescence analysis technique is used for the detection of 3-monochloropropane-1,2-diol (3-MCPD). At 100 °C and pH 8.5, FITC-modified amino silica exhibits the lowest fluorescence intensity in the presence of 3-MCPD. This can predominantly be explained mostly explained by 3-MCPD’s capacity to occupy the amino group that FITC normally binds to. The fluorescence intensity of FITC-modified amino silica was greatly quenched by 3-MCPD’s reaction with the amino group under alkaline conditions, and the fluorescence intensity is different at different reaction times, reaction pH, and reaction temperature. The effects of various 3-MCPD concentrations on the optical characteristics of FITC-modified amino silica were also investigated. Fluorescence analysis is used to obtain a linear range from 0.025 to 1.0 mg/L for 3-MCPD detection under optimal experimental conditions, with a detection limit of 0.025 mg/L and a correlation coefficient of 0.9915. The quantity of 3-MCPD in soy sauce was measured under ideal conditions. Using the optimized conditions, the contents of 3-MCPD in soy sauce were determined. These results suggest that this method is sensitive to 3-MCPD and may have a substantial application in the rapid detection of food contaminants particularly, where the quality and safety of food products are of paramount concern. |
