Result of a survey of ethyl carbamate (EC) in beer was carried out by gas chromatography-mass spectrometry (GC/MS). 217 samples were purchased from supermarkets in five cities of China. The concentrations of EC ranged from n.d. to 19.6 μg/kg with an average level of 2.2 μg/kg, and positive rate was 95.4%. Mean in domestic beer (N = 142, incidence 97.3%) was 1.8 μg/kg, lower than the 2.9 μg/kg in imported...
This study aims to develop HPLC-FLD method and verify its applicability for Ethyl Carbamate (EC) determination in Chinese spirits, and to investigate the mechanism for EC generation and its influencing factors. HPLC-FLD with prior derivatization with 9-xanthydrol was used for the EC detection. Optimal reaction condition and the parameters usually tested in the method validation were identified and...
