摘　　要：在参照GB 5009.33—2010＂食品安全国家标准食品中亚硝酸盐和硝酸盐的测定＂基础上,选择流动注射仪测定乳粉中亚硝酸盐及硝酸盐含量。确定了亚硝酸盐检出限为0.05 mg/L,加标回收率95.3%~97.0%,硝酸盐加标回收率92.1%~98.9%,精密度良好,测定结果可靠。The nitrite and nitrate content in milk powder was determined based on the measurement of GB 5009.33--2010, which processed by flow injection analysis. It was confirmed that the detection limit of nitrite was 0.05 mg/L, and the standard recoveries ranged from 95.3% to 97.0%. The detection limit of nitrate was 0.06 mg/L, and the standard recoveries ranged from 92.1% to 98.9%. The results were reliable with good precision.
