An ultra performance liquid chromatographic (UPLC) method was presented for the rapid determination of 16 kinds of food additives in beverages.The method was based on extraction with methanol mixed with water,separation on an ACQUITY UPLC~(R) BEll C_(18) column and detection with diode-array detector.All the sixteen kinds of food additives were well separated within 5.5 minutes.The limits of detection for them were more than 1.0 mg/kg,and the recoveries at three spike levels were 91.6%-100.3%,RSD was 0.66%-2.20%.
