三甲胺是肉类及水产品中常见的挥发胺,它们可以转变成具有致癌作用的N-亚硝基氨基化合物,三甲胺标准检测法为分光光度法[1],较繁琐,我们采用三甲胺衍生气相色谱法,通过多次摸索,试验证明,分析效果好,尤其适用于样品的快速检测。1材料与方法1·1仪器与试剂美国Varian公司3400Cx? Trimethylamine, a common volatile amine in meat and aquatic products, can be converted into an N-nitrosoamino compound with carcinogenic effects. The standard trimethylamine test is spectrophotometry [1], which is trivial. We used trimethylamine Derivative gas chromatography, through multiple exploration, the test proved that the analysis of good results, especially for rapid sample testing. 1 Materials and Methods 1.1 instruments and reagents Varian 3400Cx?
