摘要:

建立气相色谱-质谱联用法同时测定食醋中16种增塑剂和7种抗氧化剂的方法。方法以23种物质的特征离子进行定性定量,效果良好。23种物质标准曲线的R2均在0.99以上,方法的检出限在0.38~21.0μg/L之间,回收率和精密度分别在51.0%~123.6%和0.4%~28.3%之间。该方法简单快捷,灵敏度高,适用于食醋样品的检测,应用该方法对市售28种食醋样品进行了检测。

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.
