The occurrence of N-nitroso compounds was investigated at different stages in the production of four different beer types and in 14 retail beer samples. Only two N-nitroso compounds, namely N-nitrosodimethylamine (0.17 +/- 0.18 microgram/kg; not detected to 0.60 microgram/kg) and N-nitrosoproline (1.51 +/- 1.01 micrograms/kg; range 0.5-3.60 micrograms/kg) were detected. For moderate beer drinkers, the N-nitrosodimethylamine exposure levels are unlikely to present a significant health risk while the presence of noncarcinogenic N-nitrosoproline does not pose any hazard to human health.
对四种不同类型啤酒生产的不同阶段以及14个零售啤酒样品中的N-亚硝基化合物的存在情况进行了调查。仅检测到两种N-亚硝基化合物,即N-亚硝基二甲胺(0.17±0.18微克/千克;未检出至0.60微克/千克)和N-亚硝基脯氨酸(1.51±1.01微克/千克;范围为0.5 - 3.60微克/千克)。对于适度饮用啤酒的人来说,N-亚硝基二甲胺的暴露水平不太可能带来重大健康风险,而非致癌性的N-亚硝基脯氨酸的存在对人类健康不构成任何危害。
