摘　　要：目的:运用表面增强拉曼光谱法快速测定保健食品中非法添加的西布曲明。方法:采用表面增强试剂对保健食品进行快速处理,然后使用手持式拉曼光谱仪对其进行快速定性分析。结果:金、银溶胶两种表面增强试剂均能检测出保健食品中的西布曲明,准确判断出阳性样品和阴性样品,其中金溶胶检测效果更佳,检出限为10μg·mL^(-1)。结论:SERS结合手持式拉曼光谱仪可以应用于保健食品中非法添加的西布曲明的快速筛查,提高执法效率。Objective:To use surface-enhanced Raman spectroscopy(SERS)to rapidly determine the illegal addition of sibutramine in health foods.Method:The health foods were rapidly treated using surface-enhanced reagents,followed by rapid qualitative analysis using a handheld Raman spectrometer.Result:Both gold and silver sol-based surface-enhancing reagents were capable of detecting sibutramine in health foods,accurately identifying positive and negative samples.Among them,the gold sol showed superior detection performance with a limit of detection at 10μg·mL^(-1).Conclusion:SERS combined with a handheld Raman spectrometer can be used for rapid screening of illegally added sibutramine in health food,improving law enforcement efficiency.
