Abstract
In this study, rapid quantitative detection of histamine in beer was achieved by using nano extractive electrospray ionization mass spectrometry (nano EESI-MS) coupling with standard addition method. Based on the MS(2) experiment, histamine concentrations in three beer samples were determined to be 1.10 ± 0.12 µg/ml, 0.81 ± 0.09 µg/ml and 0.79 ± 0.09 µg/ml. The limit of detection for this method was calculated to be 0.02 µg/ml. These results show that this novel method can be used for direct, rapid and sensitive detection of histamine in beer without any tedious sample pretreatment.
