中文摘要：目的检测并分析市售奶粉中亚硝酸盐添加剂水平。方法选取6种不同品牌的市售奶粉,采用亚铁氰化钾-乙酸锌去蛋白预处理的方法,去除奶粉中蛋白质等干扰物质,运用荧光分光光度法对亚硝酸盐水平进行测定,并与奶粉中亚硝酸盐水平的国家标准(2mg/kg)进行比较评价。结果 6种奶粉的亚硝酸盐水平均低于国家标准,差异均有统计学意义(P<0.05)。结论所选6种市售奶粉的亚硝酸盐水平均未超标。

外文摘要：Objective To detect and analyse the levels of nitrite in marketed milk powder.Methods 6 brands of maketed milk powder were selected in this study.Interferents,such as protein,were removed from milk powder preliminarily by using potassium ferrocynide and zinc acetate.The levels of nitrite were detected by using fluorospectrophotometry method,and compared with na-tional standard（2 mg/kg）.Results The levels of nitrite in the 6 brands of maketed milk powder were lower than the national stand-ard limit,had statistically significant differences（P 〈0.05）.Conclusion The levels of nitrite of 6 brands of milk powders do not ex-ceed the national standard.
