A research on measuring and analyzing the fluorescence spectra of fluorescent whitening agent in soybean milk was explained in this paper. At the temperature of 30 °C, linear relationship was found good between fluorescence intensity and concentration of fluorescent whitening agent in the range of 0.015–0.25 mg/mL when the emission wavelength was 437 nm and excitation wavelength was 347 nm. Modeling analysis showed that the correlation coefficient was 0.996, the relative standard deviation (RSD) ranged from 0.45% to 0.73% and the recovery of standard addition ranged from 96.80% to 102.67%, which testified the validity of the method. This research provided a new way for detecting the unedible fluorescent whitening agent content in food production.
