摘要/Abstract

摘要： 建立了腐竹和粉丝中违禁添加剂乌洛托品的离子色谱检测法。实验优化了萃取溶剂和萃取条件。结果表明，乌洛托品在0.10~4.0 μg/g范围内线性关系良好，相关系数为0.99937。方法对腐竹和粉丝的检出限为0.079 μg/g。腐竹和粉丝的加标回收率为86%~96%，相对标准偏差为1.9%。该方法简便，快速，可用于腐竹和粉丝中乌洛托品的检测。

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
