摘 要:目的:了解某市部分市售水发产品中甲醛及Cd、Pb、Cr的污染现状。方法:用食品安全快速检测仪检测9类样品中甲醛的含量;用干灰化法进行前处理,使用火焰原子吸收分光光度法分别检测9类样品中Cd、Pb、Cr 3种重金属元素的含量。结果:9类市售水发产品样品中甲醛最低含量为2.122 mg/kg,最高含量为29.681 mg/kg;Cd元素最低含量为0.145 mg/kg,最高含量为0.628 mg/kg;Pb元素最高含量为6.106 mg/kg,部分样品未检出;Cr元素最低含量为0.168 mg/kg,最高含量为0.426 mg/kg。9类样品中甲醛、Cd、Pb和Cr含量各组差异具有统计学意义(P<0.01)。结论:某市市售部分水发产品中存在甲醛及重金属含量超标现象。Objective:To understand the current pollution of formaldehyde,cadmium,plumbum and chromium in some waterishlogged food products sold in one city.Methods:The contents of formaldehyde in 9 categories of samples were detected by the food safety rapid detector.The contents of cadmium,plumbum and chromium in 9 categories of samples were determined by flame atomic absorption spectrometry after pretreatment by dry-ashing.Results:The minimum content of formaldehyde in the 9 categories of samples was 2.122 mg/kg and the maximum was 29.681 mg/kg.The minimum content of cadmium was 0.145 mg/kg and the maximum was 0.628 mg/kg.The maximum content of plumbum was 6.106 mg/kg,while lead was undetected in some samples.The minimum content of chromium was 0.168 mg/kg and the maximum content was 0.426 mg/kg.The differences of formaldehyde contents,cadmium contents,plumbum contents and chromium contents were statistically significant(P<0.01).Conclusion:Formaldehyde and heavy metals contents in some waterishlogged food products sold in one city exceed the standards.
