| Abstract: | Objective:A gaschromatography method was developed for detecting the 3-monochloropropane-1,2-diol in food ingredient.Methods:Samples were eluted from extrelut chromatography column with diether and the mixture of hexane:diethyl ether(9:1,v/v) as eluant and detected by GC-ECD,derivatised by HFBI.Results:With experimental condition optimizing,3-monochloropropane-1,2-diol ccould be detected.Detection limit was 0.01 mg/kg,the recovery rates were 95.3%~104.4%.Conclusion:The method is reliable,fast and sensitive. |
