中文摘要：

建立了干果中糖精钠的表面增强拉曼光谱（SERS）快速分析方法。干果样品经水提取、C18固相萃取柱净化除杂后进行表面增强拉曼光谱分析。该方法的线性范围为50．0—250mg／L，检出限为0．6g／kg，回收率为80．0％～125％，相对标准偏差（RSD，n=5）不大于8．4％。结果表明该方法灵敏度高、杂质干扰小、准确度高，满足干果类食品中糖精钠的快速检测要求，在干果类食品安全质量监控方面具有良好的应用潜力。

英文摘要：

A rapid analytical method was developed for the determination of saccharin sodium salt in dry fruits by surface-enhanced Raman spectroscopy （SERS）. The saccharin in real samples was extracted with water, followed being separated and cleaned up on the activated C18 solid phase extraction column before surface-enhanced Raman scattering measurement. The linear range of this method was from 50.0 mg/L to 250 mg/L, and the detection limit was 0.6 g/kg. The good recoveries were in range of 80.0% - 125% with relative standard deviations（RSD, n = 5） no more than 8.4% . The results suggested that this method, with good anti-interference capability, was sensitive and reliable in the rapid determinattion of saccharin sodium salt in dry fruits. It is expected that this SERS based rapid analytical method possesses a great potential in monitoring the quality of dry fruits.
