Determination of sodium picosulfate in enzyme products by high-performance liquid chromatography. tandem mass spectrometry
A method based on high-performance liquid chromatography-tandem mass spectrometry was developed for the determination of sodium picosulfate in enzyme products. Sodium picosulfate is a new slimming aid that is illegally added to food products. The existing analytical methods are not suitable for application to jellies and gel candies, thus triggering the need for developing a new method. The samples were extracted with water and passed through a poly- amide cartridge. The extracts were separated on a Thermo Accucore RP. MS column (100 mm x 2. 1 mm, 2. 6 mu m) using acetonitrile-10 mmol/L ammonium acetate solution (15 : 85, v/v) as the mobile phase. The flow rate of the mobile phase was 0.3 mL/min, and the column tempera. ture was 35 degrees C Detection was carried out in the multiple reaction monitoring (MRM) mode. Quantification analysis was performed by the external standard method. The results showed that sodium picosulfate had a good linear relationship in the range of 5- 500 mu g/L, and the correla. tion coefficient (r) was 0.. 999 9. The limit of detection (LOD) was 0.05 mg/kg. The average recoveries of sodium picosulfate in different matrices were in the range of 89.2% – 111.8%, with the relative standard deviations (RSDs) of 2.. 5% – 10.4%. The method was applied to the analy. sis of 152 samples, and 58 positive samples were detected. The positive rate was 38.2%. The developed method is accurate and sensitive, and it is suitable for detecting sodium picosulfate in enzyme products.
