摘要
为探讨矿物元素指纹对羊肉产地溯源的有效性,找寻表征地域特性的元素指标,利用电感耦合等离子体质谱仪分析中国内蒙古自治区阿拉善盟、锡林郭勒盟和呼伦贝尔市3个牧区,及重庆市和山东省菏泽市2个农区脱脂羊肉和土壤样品中4种常量元素(K、Ca、Na、Mg)和13种微量元素(V、Mn、Fe、Cr、Ni、Cu、As、Be、Sb、Zn、Se、Ba、Tl)的含量,对其进行方差分析、相关分析和判别分析。结果表明,羊肉中矿物元素含量组成在地域间有明显差异,农区元素含量普遍高于牧区。脱脂羊肉中Ca、Zn、Be、Ni、Fe、Ba、Sb、Mn和Se9种元素含量的地域差异与土壤相关,它们对农牧区的正确判别率达90%以上,对5个地域的正确判别率在70%~100%之间。利用羊肉中矿物元素指纹分析技术可鉴别和追溯羊肉的产地来源,为羊肉及其他食品的产地溯源研究提供方法参考。
