OBJECTIVE
The AOAC 2000.01 method was validated in order to establish Chinese national standard for determination of 3-monochloropropane-1,2-diol (3-MCPD) in foods.
METHODS
Using gas chromatography with mass spectrometric detection and incorporating the using of a deuterated internal standard of 3-MCPD, the recovery test were carried out by fortified 3-MCPD standard in soy sauces, flour and salami.
RESULTS
Linearity, precision and recovery were complied with the method AOAC2000.01 that was adopted First Action by AOAC International. The limit of detection was 0.005 mg/kg.
CONCLUSION
AOAC2000.01 was adopted as the Chinese national standard GB/T 5009.191.
目的
对AOAC 2000.01方法进行验证，以建立食品中3-一氯丙二醇（3-MCPD）测定的中国国家标准。
方法
采用气相色谱-质谱联用法，加入3-MCPD氘代内标，通过向酱油、面粉和萨拉米香肠中添加3-MCPD标准品进行回收率试验。
结果
线性、精密度和回收率均符合AOAC国际组织首次采用的AOAC2000.01方法要求。检测限为0.005mg/kg。
结论
AOAC2000.01被采用为中国国家标准GB/T 5009.191。
