摘  要:
利用气相色谱法分析牛肉辐照前后碳氢化合物的类型与浓度差异,建立了一种能判别辐照牛肉的鉴定方法。本试验通过正己烷溶剂萃取,Florisil柱分离和气相色谱分析,对辐照牛肉产生的6种碳氢化合物进行了定性和定量分析。研究结果表明,牛肉经辐照处理后,显著产生1,7-C16:2(1,7-十六二烯),而在未辐照的牛肉中没有检测到,因而1,7-C16:2是鉴定牛肉是否经过辐照处理的最适合标志物。

摘  要:
A method has been developed to detect irradiated beef by GC analysis of differences of the types and contents of hydrocarbons between unirradiated and irradiated beef.Six hydrocarbons in irradiated beef were qualitatively and quantitively determined by procedures of extraction by hexane,separation by Florisil cloumn and GC analysis.The results shows that no 1,7-C16:2(1,7-hexadecadiene) has been found in unirradiated beef,while it is significantly detectable in the irradiated sample.Therefore,1,7-C16:2 is the best probe to determin whether beef is treated by irradiation or not.
