摘要
建立优化的气相色谱法测定食品中甜蜜素的含量．通过对测定过程中的主要影响因素进行研究，改进国标法GB／T5009．97—2003．实验证明，甜蜜素在浓度范围为0-2．5mg／mL内具有良好的线性关系和较低的相对标准偏差，加标回收率在96-102％之间．本检测方法合理、适用、准确，操作便捷，测定结果令人满意．同时，本文对前处理中影响因素的影响提出了解决方法和质控条件．
An optimized determination method of sodium cyclamate in food was established with gas chromatography. By studying the main influencing factors of the test process, national standards method was improved. The results showed that this method has good linearity and low RSD （relative standard deviation）when the concentration of sodium cyclamate is in the range of 0 - 2.5 mg/mL ,with the recoveries of 96%-102%. The detection method is reasonable, ap- plicable and accurate, with easy operation and satisfactory results, which is suitable for the determination of sodium cyclamate in food. Analytical results are satisfactory. Meanwhile, solutions and quality controling condition were proposed for the influencing factors in pre-treatment.
