[Determination of 3-monochloropropane-1,2-diol in foods by GC-MS using stable isotope dilution technology].
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.


CONCLUSIONS
AOAC2000.01 was adopted as the Chinese national standard GB/T 5009.191.
