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.
