北京市场液体调味品中3-氯-1,2-丙二醇污染状况研究

:1999年英国等欧洲国家在中国及中国香港产的调味品中检测出较高含量的 3-氯 - 1,2 -丙二醇 3-monochloropropane- 1,2 - diol(简称 3- MCPD) ],根据英国 Food Advisory Com mittee (FAC)的建议 ,已停止这些产品在英国的销售。本研究提供了在中国市场销售的部分液体调味品中的 3- MCPD的污染状况 ,30种酱油、蚝油及类似产品于 2 0 0 0年 3～ 4月购自北京 6家超级市场 ,采用毛细管气相色谱 -质谱法 ,方法的检出限为 0 .0 1mg/kg。在 30种检测样品中 15种未检测出 3- MCPD;2种在比较低的水平 (0 .0 1～ 0 .0 2 mg/kg) ,5种在比较高的水平 (>1mg/kg)。

Survey of 3-monochloropropane-1,2-diol in soy sauce and similar products

A survey of 3-monochloropropane-1,2-diol (3-MCPD) in soy sauce and other similar products available in China has been completed. Thirty samples of soy, oyster sauce and other sauces were purchased from six supermarkets in Beijing during March and April 2000 and analysed using a validated method of analysis by capillary gas chromatography with mass spectrometric detection. The UK Food Advisory Committee (FAC) has advised a level of 0.01 mg/kg for 3-MCPD. Following reports that high levels had been detected in some brands of soy sauce in China. 3-MCPD was undetectable with a detection limit of 0.01 mg/kg in 15 of the 30 samples analyzed in the survey, with a further 4 samples (13.3%) containing very low levels of between 0.01 and 0.02 mg/kg. However, 5 samples (16.7%) contained 3-MCPD levels above 1 mg/kg.
