摘要：

为了解我国市售超高温灭菌（UHT）牛奶中微量元素含量及不同品牌间差异，从我国17个城市超市采集了29个国产品牌的96批次UHT牛奶及28个进口品牌的53批次UHT牛奶，分析了17种微量元素的含量，并比较了国产品牌与进口品牌UHT牛奶中微量元素含量差异。实验采用微波消解前处理和电感耦合等离子体质谱（ICP-MS）法测定牛奶中17种微量元素含量，加标回收率为90.9%~109.6%。分析结果表明，国产品牌和进口品牌UHT牛奶中元素钒（V）、铬（Cr）、钴（Co）、镍（Ni）、镓（Ga）、银（Ag）、铊（Tl）、铀（U）检出率分别为2.08%~88.54%和1.89%~92.45%，锰（Mn）、铁（Fe）、铜（Cu）、锌（Zn）、硒（Se）、铷（Rb）、锶（Sr）、铯（Cs）、钡（Ba）检出率均为100.00%；国产品牌与进口品牌UHT牛奶中元素Cu、 Zn、Se、Ni和Sr含量差异显著（P<0.05），V、Cr、Mn、 Fe、Co、Ga、Rb、Ag、Cs、Ba、 Tl和U含量差异不显著（P>0.05）。

Abstract:

In order to understand the trace elements content in UHT milk sold in domestic market, and differences among different brands, UHT milk samples of 29 domestic brands, 96 batchs from 17 cities were analyzed. 17 trace elements contents in 28 import brands and 53 batch UHT milk were also analyzed, and the differences in trace element between domestic brand and import brand were compared. By microwave pretreatment and ICP-MS method, the contents of 17 trace element in UHT milk were tested. The spiked recovery was 90.9%~1096%. The results indicated that positive rate of Mn, Fe, Cu, Zn, Se, Rb, Sr, Cs and Ba were all 100.00%, while that of V, Cr, Co, Ni, Ga, Ag, Tl and U were 2.08%~88.54% and 1.89%~92.45% in domestic brands and import brands, respectively. The differences in concentration of Cu, Zn, Se, Ni and Sr between domestic and import brand were significant (P<0.05), while that in concentration of V、Cr、Mn、 Fe、Co、Ga、Rb、Ag、Cs、Ba、 Tl and U were not significant(P>0.05).

Key words: UHT milk, ICP-MS, trace element
