A method for the determination of banned additive,methenamine,in dried beancurd stick and bean vermicelli by ion chromatography was established.The extraction conditions and extraction solvents were optimized.Results showed a good linearity in the range of 0.10~4.0 μg/g for methenamine with the related coefficient of 0.99937.The detection limit of the proposed method for dried beancurd stick and bean vermicelli was 0.079 μg/g.Spiked recoveries were in the range of 86%~96% and the relative standard deviation was 1.9%.The proposed method is simple and rapid and can be applied to the analysis of methenamine in dried beancurd stick and bean vermicelli.
