Aflatoxin B1 and sterigmatocystin survey in beer sold in China

ABSTRACT

A total of 101 samples of beer from the Chinese market were analysed for the presence of aflatoxin B₁ (AFB₁) and sterigmatocystin (STC), using methods based on liquid chromatography–tandem mass spectrometry. The limit of quantification and the limit of detection in beer were 0.1 and 0.03 µg/kg, respectively. Recoveries of AFB₁ and STC from spiked beer samples were 97.8–103.6% and 92.7–102.1%, respectively. None of the beer purchased samples were contaminated with AFB₁ or STC.
