Abstract:

A method for simultaneous determination of 16 plasticizers and 7 antioxidants in vinegar was established
by GC-MS. Desired results were achieved in quantitative and qualitative analysis of the 23 food additives based on their
characteristic ions. All the established standard curves were characterized by a correlation coefficient above 0.99. The limits
of detection of the method were 0.38－21.0 μg/L, and the recoveries and precision (RSD) were 51.0%－123.6% and 0.4%－
28.3%, respectively. This method proved to be simple, fast and sensitive, and was successfully applied to determine 28
marketed vinegar samples.

Key words: vinegar, plasticizers, antioxidants, gas chromatography-mass spectrometry (GC-MS)
