目的了解潍坊地区部分食品原料中铝本底含量状况及危险性,为指导安全消费及食品安全风险监测系统提供科学依据。方法 2014-2015年,开展潍坊地区部分食品原料中铝本底含量监测检验,方法采用电感耦合等离子体光谱法。结果 2014-2015年合计检测食品883份,铝检出587份,检出率为66.48%。其中植物性食品原料检出率为55.05%,动物性食品原料检出率为77.63%,差异有统计学意义(χ~2=16.235,P<0.05);2014年总检出率为66.34%,2015年为66.60%,年份间相比较差异无统计学意义(χ~2=0.172,P>0.05)。植物性食品原料中粮谷类检出率显著高于蔬菜类、水果类,差异有统计学意义(χ~2=17.576,P<0.05);动物性食品原料中畜肝、畜肾及水产品类食品原料检出率显著高于畜肉、禽肉、鲜蛋、生乳(χ~2=19.515,P<0.05)。不同的采样地点铝的检出率差异无统计学意义(χ~2=0.030,P>0.05)。结论某些食品原料铝本底含量较高,直接影响其加工产品中铝残留量,存在一定的食品安全风险。
Objective To understand the status and risk of aluminum background in some food ingredients in Weifang, and to provide a scientific basis for guiding safety consumption and food safety risk monitoring system. Methods From 2014 to 2015, we carried out the monitoring of aluminum content in some food ingredients in Weifang by inductively coupled plasma spectrometry. Results A total of 883 food samples were detected in 2014-2015, 587 aluminum samples were detected, with a detection rate of 66.48%. Among them, the detection rate of vegetable food raw materials was 55.05%, and the detection rate of animal food raw materials was 77.63% (χ ~ 2 = 16.235, P <0.05). The total detection rate in 2014 was 66.34% 66.60% in 2015, there was no significant difference between years (χ ~ 2 = 0.172, P> 0.05). The detection rate of grains and cereals in plant foodstuffs was significantly higher than that in vegetables and fruits (χ ~ 2 = 17.576, P <0.05); animal foodstuffs including livestock liver, livestock kidney and aquatic products The detection rate of raw materials was significantly higher than that of meat, poultry, fresh eggs and raw milk (χ ~ 2 = 19.515, P <0.05). There was no significant difference in the detection rate of aluminum in different sampling sites (χ ~ 2 = 0.030, P> 0.05). Conclusion Some aluminum raw materials with high background content directly affect the amount of aluminum residues in their processed products, which poses some food safety risks.
