Abstract:
Objective A method for the determination of 4-methylimidazole in soy sauce by capillary gas chromatography was studies.Methods The method consisted of a methylene chloride to elution,followed by concentration of the eluate.N,N-Dimethylaniline(IS) was added in and GC analysis of the eluate,prior to GC analysis.The GC analysis was carried out by DB-FFAP capillary column and nitrogen phosphorus detector(NPD).Results The linear range was 4.9mg~1.5?102 mg/L and the limit of detection was 0.16 ug/L.The average recoveries were 97.25%and 99.44% by stand addition method in 0.0102mg and 0.0602mg 4-methylimidazole.Conclusion The method was simple,rapid and sensitive.A useful method for determining 4-methylimidazole in soy sauce was provided for forensic analysis.
