It is believed that the method described in this article may be useful for routine analysis of methylcarbamate and ethylcarbamate in numerous food samples.

Methylcarbamate (MC) and ethylcarbamate (EC) are toxic compounds that commonly exist in fermented food and beverages. In order to estimate the risk for their exposure, a sensitive simultaneous analytical method is required 

A simultaneous determination of MC and EC was described based on derivatization with 9-xanthydrol and consecutive detection using gas chromatography--massspectrometry. The derivatization of MC and EC was performed directly in food or beverages and the reaction conditions were established through changing various parameters. The detection and the quantification limits were 0.01-0.03 mug/kg and 0.03-0.1 mug/kg, respectively, and the interday relative standard deviation was less than 12 % at concentrations of 2.0 and 50 mug/kg. MC and EC were measured from 0.4 mug/kg to 85.8 mug/kg in sixteen Korean fermented foods and eleven beverages. 

A simple, sensitive method to detect MC and EC in several solid foods and liquid foods was developed based on derivatization with 9-xanthydrol for 10 min at an ambient temperature.

The article is published online in the Chemistry Central journal and is free to access.
