The sample to be tested was sonicated with methanol and a blank solution was made at the same time. A mixed standard working solution with a concentration gradient of 20-200 μg / mL was prepared with methanol. The concentration of benzyl acetone was in the range of 0.5-5 μg / m L, the use of gas chromatography - mass spectrometer for the standard working solution, blank solution and sample solution analysis and detection, the relevant chromatograms, sample
