摘　　要：为实现南疆地区不同品种绵羊肉的产地溯源和鉴别,采用电感耦合等离子体-质谱比较南疆4个地方品种绵羊肉中25种矿物质元素含量差异,并基于方差分析、正交偏最小二乘判别分析、分层聚类分析及线性判别分析确定特征元素。结果表明,不同品种绵羊肉中Na、Mg、K、Ca、P、Fe、Zn、Rb、V、Cu、Cr、Se、Sr、Cd、Ag、Cs 16种矿物质元素含量在品种间存在显著差异,进一步筛选出Se、Mg、P、Sr、Ag作为不同品种绵羊肉产地溯源和鉴别的特征矿物质元素,其中Se、Mg、Sr、Ag元素可以作为和田羊肉的特征矿物质元素,P元素可以作为策勒黑羊肉的特征矿物质元素,Mg和Sr可以作为多浪羊肉的特征矿物质元素,Sr可以作为和田白羊肉的特征矿物质元素。据此建立判别函数模型,交叉检验和回代检验的整体判别正确率均为100%,表明所筛选出的5种矿物质元素能够用于鉴别南疆4个地方品种绵羊肉,所建立的判别模型有效。因此,基于矿物质元素差异的分析方法能够实现南疆4个地方品种绵羊肉的产地溯源和鉴别,对新疆地方特色品种绵羊肉保护具有重要意义。For geographical traceability and breed discrimination of lamb meat in Southern Xinjiang,inductively coupled plasma-mass spectrometry was used to analyze the differences in the contents of 25 mineral elements in lamb meat from four local breeds in this region.Characteristic elements were determined by analysis of variance,orthogonal partial least squares-discriminant analysis(OPLS-DA),hierarchical clustering analysis(HCA),and linear discriminant analysis(LDA).The results showed that there were significant differences in the contents of 16 mineral elements including Na,Mg,K,Ca,P,Fe,Zn,Rb,V,Cu,Cr,Se,Sr,Cd,Ag,Cs among lamb meat from different breeds.Furthermore,Se,Mg,P,Sr,and Ag were selected as the characteristic mineral elements for traceability and discrimination.Se,Mg,Sr,and Ag were determined as the characteristic mineral elements in Hetian lamb,P in Celle black lamb,Mg and Sr in Duolang lamb,and Sr in Hetian white lamb.Based on these characteristic elements,a discriminant model was established,and the overall accuracy rate was 100%in both cross-validation and back-validation tests,demonstrating that the five selected mineral elements are effective for distinguishing the lamb meat from four local breeds in Southern Xinjiang,confirming the validity of this model.Therefore,the analytical method based on mineral element differences allows traceability and identification of lamb meat from four local breeds in Southern Xinjiang,which is of great significance for the protection of local specialty sheep breeds in Xinjiang.
