目的 通过对2013年昆明市市售乳制品中总砷含量进行分析, 进而了解昆明市市售乳制品中总砷污染情况。方法 按照GB/T 5009.11-2014《食品安全国家标准 食品中总砷及无机砷含量测定》中所述的湿法消解-原子荧光光谱法进行检测分析, 根据GB 2762-2012《食品安全国家标准 食品中污染物限量》对乳制品中总砷含量标准进行评价。结果 2013年共抽检样品120份, 其中巴氏消毒乳20份, 灭菌乳36份, 发酵乳64份。共有8份样品检出总砷, 检出率6.7%; 1份样品含量超标, 超标率0.8%。其中巴氏消毒乳、灭菌乳、发酵乳的检出率分别为: 0%、2.8%、10.9%, 超标率分别为0%、0%、1.6%。结论 2013年昆明市市售乳制品中总砷含量检出率较低, 砷的污染程度不严重, 处于安全水平。
Objective To analyze the total arsenic content in dairy products sold in Kunming city in 2013, in order to investigate the total arsenic contamination in dairy products sold in Kunming city. Methods Samples were determined by wet digestion-atomic fluorescence spectrometry according to GB/T 5009.11-2014 National food safety standard-Determination of total arsenic and inorganic arsenic in foods, and the standard of total arsenic in dairy products was evaluated according to GB 2762-2012 National food safety standard-Limit of pollutants in foods. Results In 2013, a total of 120 samples were sampled, including 20 cases of pasteurized milk, 36 cases of sterilized milk, and 64 cases of fermented milk. Total arsenic was detected in 8 samples, with the detection rate of 6.7%, and 1 samples exceeded the standard, with the exceeding standard rate of 0.8%. The detection rates of pasteurized milk, sterilized milk and fermented milk were 0%, 2.8% and 10.9%, respectively, and the exceeding standard rates were 0%, 0% and 1.6%, respectively. Conclusion The detection rate of total arsenic in dairy products sold in Kunming was lower in 2013.
