Abstract: 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.

Key words: methenamine, dried beancurd stick, bean vermicelli, ion chromatography
