摘  要:
建立一种对不同食品中低含量甜蜜素的快速气相色谱-质谱(GC-MS)检测方法。不同样品(含蛋白、含脂肪等液、固体试样)经过除杂、超声波提取、衍生,然后经GC-MS定性、定量测定。实验表明,该方法检测限为40mg/kg(信噪比3.0),甜蜜素加标回收率范围为88.0%~108.0%,相对标准偏差(RSD)小于7.16%,说明该实验方法满足食品中低含量的甜蜜素检测要求。

摘  要:
A gas chromatograph-mass spectrometric (GC-MS) method was developed for the rapid determination of sodium cyclamate in foodstuffs. Samples were extracted with hexane in an ultrasonic field, and the extracts were analyzed by GC-MS after derivatization with a mixture of 50 g/L sodium nitrite solution and 100 g/L sulfuric acid (5:5, V/V). The detection limit was 40 mg/kg (signal/noise ratio = 3.0). The recoveries for cyclamate in six spiked samples ranged from 88.0 % to 108.0% and the relative standard deviations (RSDs) were less than 7.16%. This method has obvious advantages such as high sensitivity, specificity and simplicity versus other methods reported previously, therefore can be used to detect effectively low-level sodium cyclamate in foods
